API Comparative Motor Oil Testing
AMSOIL Synthetic 10W-30 Motor Oil (ATM) and 10 competing conventional and synthetic10W-30 motor oils were subjected to a series of API motor oil tests. The competing oils included petroleum-based Castro GTX Drive Hard, Mobil Drive Clean, Pennzoil with Purebase, Quaker State Peak Performance and Valvoline, as well as synthetic-based Valvoline Synpower, Quaker State, Castrol Syntec, Pennzoil and Mobil SuperSyn Multi-Vehicle.
Seven API tests were run on the motor oils. The Thin-Film Oxygen Uptake Test (TFOUT) measures the oxidation stability of engine oils. The High Temperature/High Shear Test (HTHS) measures a lubricant's viscosity under severe operating conditions. The NOACK Volatility Test measures the evaporation loss of oils in high temperature service. Pour Point indicates the lowest temperature at which a fluid will flow. Total Base Number (TBN) is the measurement of a lubricant's reserve alkalinity for combating acids. The Cold Cranking Simulator Test (CCS) measures a lubricant's viscosity at low temperatures and high shear rates. The Four-Ball Wear Test measures a lubricant's wear protection properties. The impressive test results show AMSOIL Synthetic 10W-30 Motor Oil outperformed the competitors in each test.
Thin-Film Oxygen Uptake (ASTMD-4742)
The Thin-Film Oxygen Uptake Test evaluates the oxidation stability of lubricating oils. A mixture of the test oil and chemistries found in gasoline engine operation (oxidized/nitrated fuel, soluble metals and distilled water) are placed in a test vessel, which is pressurized with oxygen and placed in a heated bath. Anti-oxidant breakdown is evident when the oxygen pressure in the vessel rapidly decreases. At this point, the induction time (break point) of the oil is recorded. As shown in the graph, AMSOIL Synthetic 10W-30 Motor Oil had the highest induction time of all the tested oils. In fact, it didn't reach its break point in over 500 minutes of testing.
The superior oxidation stability of AMSOIL Synthetic 10W-30 Motor Oil allows it to effectively resist the formation of engine deposits and sludge, keeping engines running clean and efficient and extending oil life. It also resists thickening, maintaining its superior wear protection and lubricating properties and maximizing fuel efficiency.
High Temperature/High Shear (ASTM D-4683)
The High Temperature/High Shear Test measures a lubricant's viscosity under severe hightemperature and shear conditions that resemble highly-loaded journal bearings in fired internal combustion engines. In order to prevent bearing wear, it is important for a lubricant to maintain its protective viscosity under severe operating conditions. The minimum High Temperature/High Shear viscosity for a 30 weight oil is 2.9 cP. As shown in the graph, AMSOIL Synthetic 10W-30 Motor Oil surpasses this minimum standard and displayed the highest High Temperature/High Shear viscosity in the group.
The superior viscosity retention of AMSOIL Synthetic 10W-30 Motor Oil in the face of severe temperature and shear conditions allows it to provide continuous, unsurpassed protection for engine bearings, extending equipment life and preventing wear.
NOACK Volatility (ASTM D-5800)
The NOACK Volatility Test determines the evaporation loss of lubricants in high temperature service. The more motor oils vaporize, the thicker and heavier they become, contributing to poor circulation, reduced fuel economy and increased oil consumption, wear and emissions. A maximum of 15 percent evaporation loss is allowable to meet API SL and ILSAC GF-3 specifications. As shown in the graph, AMSOIL 10W-30 Synthetic Motor Oil outperformed its nearest competitor by over 30 percent.
The extremely low volatility of AMSOIL Synthetic 10W-30 Motor Oil allows it to maintain its superior protective and performance qualities throughout extended drain intervals, even when faced with severe operating temperatures. In addition, oil consumption and emissions are minimized and fuel efficiency is maximized.
Pour Point (ASTM D-97)
The Pour Point Test determines the lowest temperature at which a lubricant will flow when cooled under prescribed conditions. The lower a lubricant's pour point, the better protection it provides in low temperature service. As shown in the graph, AMSOIL Synthetic 10W-30 Motor Oil has the lowest pour point of the tested oils.
The low pour point of AMSOIL 10W-30 Synthetic Motor Oil allows it to maintain its fluidity in extremely low temperatures, reducing drag on moving vehicle parts, providing critical engine components with quick, essential lubrication and easing startup in cold temperatures. Wear is greatly reduced and equipment life is extended.
Total Base Number (ASTM D-2896)
Total Base Number (TBN) is the measurement of a lubricant's reserve alkalinity, which aids in the control of acids formed during the combustion process. The higher a motor oil's TBN, the more effective it is in suspending wear-causing contaminants and reducing the corrosive effects of acids over an extended period of time. As shown in the graph, AMSOIL Synthetic 10W-30 Motor Oil has the highest TBN of the tested oils.
The high TBN of AMSOIL Synthetic 10W-30 Motor Oil allows it to effectively combat wear-causing contaminants and acids, providing superior protection and performance over extended drain intervals.
Cold Crank Simulator (ASTM D-5293)
The Cold Crank Simulator Test determines the apparent viscosity of lubricants at low temperatures and high shear rates. Viscosity of lubricants under these conditions is directly related to engine cranking and startability. The lower a lubricant's cold crank viscosity, the easier an engine will turn over in cold temperatures. 10W motor oils are tested at -25°C and must have a viscosity below 7000 cP to pass. As shown in the graph, AMSOIL Synthetic 10W-30 Motor Oil is well below the maximum requirement, while many of the competing oils barely pass.
The low cold crank viscosity of AMSOIL Synthetic 10W-30 Motor Oil reduces drag on moving engine parts and allows engines to achieve critical cranking speed in extremely frigid temperatures. Engines turn over quickly and dependably in the coldest winter temperatures.
Four Ball Wear (ASTM D-4172)
The Four Ball Wear Test determines the wear protection properties of a lubricant. Three metal balls are clamped together and covered with the test lubricant, while a rotating fourth ball is pressed against them in sliding contact. This contact typically produces a wear scar, which is measured and recorded. The smaller the average wear scar, the better the wear protection provided by the lubricant. As shown in the graph, AMSOIL Synthetic 10W-30 Motor Oil produced the smallest wear scar of the tested lubricants.
AMSOIL Synthetic 10W-30 Motor Oil provides unsurpassed protection against engine wear. Equipment life is extended, and repairs, downtime and expenses are reduced.
AMSOIL INC.has been the leader in synthetic motor oil formulationsince its introduction of the world's first API rated synthetic motor oil in 1972. By specializing exclusively in the synthetic lubricant technology, AMSOIL is able to optimize the most advanced chemistries available. The "Genuine Synthetic PAO Formulated" designation displayed on AMSOIL packaging indicates that the oils are formulated with Polyalphaolefin (PAO) synthetic base stocks. This chemistry is the industry's premier base stock technology. Unlike conventional mineral-based chemistries, AMSOIL PAO base stocks contain fullysaturated, hydrogenated molecules and are free of wax and other impurities. Combined with an exact balance of premium additives, itdelivers superior hot and cold temperature performance, resists oxidation and acid formation and provides long-term wear protection. AMSOIL "General Synthetic PAO Formulated" oils have shattered the parameters of the most rigorous industry testing and set the standard for all other motor oils.

disregard the previous post i found the results myself.I found the information very informative.I was very surprised that amsoil was far superior in all the tests.although i wish havoline conventional and havoline synthetic had been included .Steve do you know why they weren't included?It is cold outside and i didn't have anything better to do so i went through each catergory and ranked each oil in each catergory and then did an overall average.according to my system amsoil stomped the competition.what shocked me though was mobil-1 finished #3 according to my overall average valvoline synthetic is a better choice than mobil-1 I bet most people thought mobil-1 to be better.also I didn't like mobil 1 results in four ball wear test either.does that mean it has a weak anti wear additive?also steve do you have any test data on the havoline products?

andys1960,
Why you ask? Better to compare apples to apples.
__________________________________________________
I answered your concern on another thread, I will repeat it here.
Havoline does not know what type of oil they want to be. The oil has different additives and/or characteristics depending upon where it is mixed.
Havoline is a Hydrocracked "Pretend" Synthetic Oil (a Group III base oil --- vs. a Group IV or Group V which are the base oils used in 100% TRUE Synthetics). Thanks to Castrol (for screwing up the labeling in the Lubricants Industry), any Dino that has been refined an additional time can be referred to as Hydrocracked "Synthetic". Layman's terms: It's like an ugly girl wearing 1/2 inch of makeup to be beautiful.
However, just as all oils are not alike, ... not all hydrocracked oils are bad. Some are quite good, and there are some exceptional hydrocracked oils in the marketplace. The quality of any oil is not just the "base" oil ... but also the additive package. That is why the better quality oils cost more. Simple isn't it --- and that is why Royal Purple, Redline, Schaeffers, and Amsoil all cost more than Mobil1.
The oils with "Equilon" on the bottle don't get much respect (Not the best for "cold Crank" capabilities and Viscosity Stability protection. Me thinks they used a weak additives package to cut costs. Note If you live in the "Sunbelt" where you will have mild winters you will be alright. If you live in the North with harsh winters --- save the Havoline for the Summer. Use it in everything that you own (especially your lawn and garden equipment, where it is better suited) and use it as fast as possible (this is an oil that should not be run more than 3,000 miles), then switch to something better --- even if it's Mobil1 --- your engine deserves it.

The way to differentiate Chevron Oils (since they market so many different oils under different labels, --- in order of quality:
Chevron Delo 400
Texaco Ursa Premium
Chevron Supreme
Chevron/Texaco Havoline
Chevron RPM
Texaco Ursa Super Plus, etc.
Plus the Gulf Lubricants that Chevron makes.
... and marketed by Amoco are the Amoco lubricants that are made by Chevron.
__________________________________________________
For those that did not see the post Andy was referring to, here is is reprinted for your convenience:
I always thought Havoline to be a good "dino" oil, until lately when it started getting bashed because of Equilon (read below). You can blame the oil companies for the confusion. With so many changes, mergers, and acquisitions in the oil industry, it's almost impossible to keep up with who is making what and who is selling what, and very difficult to have any brand loyalty. Up until just a few years ago, you knew who you were dealing with, --- now you have no idea at all.
There are three very different Havoline 5w-40's in the market place currently. One is produced by Shell and the other by Equilon --- Equilon is no longer producing (they were - pardon my French - CRAP), but some of their supply is still around (and will be for many months) --- AND THE "NEW" Havoline is (I believe) a "relabeled" Shevron Supreme. VERY CONFUSING FOR CONSUMERS.
(If you recall --- as part of "the deal", the Havoline Lubricants Division was handed from Shell to Chevron/Texaco). Some of the Havoline oil at the "big box" stores is not made by Chevron/Texaco but is the old stock made by Equilon (Shell). The Flash Points, Pour Points, and Viscosity Index numbers for all the products are quite different. The $1.99 qt. is the "old stuff" (Group III dino). I have seen it in some of the "big box" stores in my area.
The "NEW" Havoline reaching the stores (as stated earlier) may be a "re-labeled" Chevron Supreme product. The data sheets for both Chevron Supreme and the "latest" Havoline synthetic 5w-40 read absolutely identically ---number for number. Of at least equal interest are the respective Material Safety Data Sheets (MSDS). The sheets read identically except for identifying names and catalog numbers.
--------------------------------------------------
I'm still holding out (and holding my nose) on giving an opinion regarding Havoline until they figure out who is manufacturing and blending, and I see the final spec sheet and MSDS.
Who knows --- by the time you read this they might have changed again.
__________________________________________________
To add to my above comment I posted:
"Up until just a few years ago, you knew who you were dealing with, --- now you have no idea at all." Maybe this addition helps:
TEXACO was "Texaco" until they murged with Shell to form Equilon. Shell sold the Texaco fuels division to Chevron but kept all the lubricant formulas and divisions. If you see Havoline with Equilon on the bottle, it is made by Shell. If you see Havoline with Chevron/Texaco on the bottle, it is made by Chevron. I believe Shell has the right to make Havoline for the next nine (9) months. What brand or name will it be a year from now? Your guess is as good as mine.
Shell kept the formulas for all Texaco lubricants. They are producing the industrial oils but they are using the Shell name. They are only using the Texaco name on the Havoline products.
AMOCO fuels was purchaed by BP and the lubricants division of AMOCO was purchaed by Chevron and BP/AMOCO purchaed Castrol Lubricants.
Pennzoil purchased Quaker State which is soon to be purchased by Shell.
--------------------------------------------------
I have also spoken with a Chevron Technician via their website and asked them if the Chevron Supreme is a 100% FULL Synthetic and if their Havoline counterpart was PAO or Group III base. Due to the confusion on the spec sheet (read below) I picked up the phone. I confirmed via telephone that Chevron/Texaco is a group III and they have no immediate plans for a 100% PAO oil. The confusion in their spec sheet states that they use 55% PAO and a 15% ester, and some Group III (hydorcracked) --- and they use the funny use of the word "or", as in stating that at any givin time they can use MORE Group III base and LESS PAO.
Bottom Line --- The response was (except for the arctic grade 0w-30 oil --- ALL of the Chevron synthetic oils are Group III based (hydrocracked dino) oils, and not Group IV / Group V Full Synthetics. Therefore the "NEW" Havoline 5w-40 is a hydrocracked dino oil.
--------------------------------------------------
Hope this clears the air.

Here is a ZINGER: A lot of Group III oils are now adding small amounts of PAO and Esters (in the formula and on the label) to fool consumers into believing they are 100% TRUE Synthetics. Don't be fooled.I don't think much of Group III oils masquerading as TRUE synthetics.
--------------------------------------------------
A short list of oils beginning to masquerade
as 100% TRUE Synthetic Oils:
Valvoline Synpower, Pennzoil Synthetic, Castrol Syntec, Havoline Synthetic, SuperTech Synthetic, QuakerState Synthetic, Exxon Superflo Synthetic

FAKE synthetics: Valvoline (Pathetic) Synthetic, Havoline (Pathetic) Synthetic, Pennzoil (Pathetic) Synthetic, OuakerState (Pathetic)Synthetic, and Castrol (Pathetic) Syntec are all FAKE. Is this the equivalant of a non-alcoholic beer?

Andys1960,
Valvoline is NOT better than Mobil1.
Dex,
Thanks for your addition and helping to point out that a lot of oils that advertise themselves as synthetic ... really aren't synthetic at all. A TRUE Synthetic Oil uses Group IV or Group V base oils (Group IV is PAOs (Polyalfaolefins) while Group IV is the esters), and pretend synthetics use hydrocracked Group III (Dino). Also, what a lot of the pretend synthetics are doing is adding a small amount of Group IV or Group V to their Group III so they can mis-advertise.
__________________________________________________
Andys1960,
First, when anyone has ever asked me to compare Amsoil vs. "______", or "_____" vs. Mobil1, I make every attempt to be fair and unbiased. I have recommended Mobil1 to those that still believe they should change their oil every 3k miles. I have recommended Castrol Syntec (hydrocracked dino - and NOT a true synthetic) to those that still believe that synthetics are bad.
__________________________________________________
Valvoline
Valvoline Synthetic uses a Group III base oil, so it's not technically a synthetic, but hydrocracked dino ... a PRETEND SYNTHETIC.
Valvoline's additive package is pretty weak. I used to recommend their MaxLife ... but not any more. They weakened the additives package so that they could offer a cheaper oil on the Walmart shelves.
If you are choosing between Havoline, Valvoline, or Mobil1 ... choose Mobil1.
__________________________________________________
Mobil1
Mobil1 is a very good oil, however in some engines it does not do very well because of it's thinner nature. In those engines a different synthetic would show better wear numbers. While I do think Mobil1 is too thin for some engines, it can be thickend up by adding a qt. of 15w-50.

If you would like information as to how various oils do in various engines, visit this site http://www.bobistheoilguy.com/ or specifically the usued oil analysis (UAO) forum at http://theoildrop.server101.com/ubb/ultimatebb.php?ubb=forum;f=3. The AmsoilSponsor frequents this site and should have mentioned it as well. He also happened to present one of the best UAO for Amsoil on the site. Many are less impressive. You will find that Amsoil is one of the best performing oils, but certainly not superior as the above charts would suggest. You will also find a few UAOs from 4.7L 4x4 QC Dakotas including mine.
For a discussion on this board regarding the usefulness of UAOs, see http://www.dodgedakota.net/boards/gen/14738.html.For many reasons, I think the information you'll find on Bob's site will be much more informative and pertinent than the above charts.
