#1 = Synthetic as I am sure Mr. " Amsoil " will
verify..
#2 10w30 Pennzoil or equivalent..
Do NOT use 20 w 50 - this is for badly worn
or at least engines exposed to heavy hauling
high heat

I use Castrol GTX 10W30 dino, chage it every 3,000 miles, which for my vehicle is about 3 months. As mentioned above, 20W50 is much too heavy for the 3.9, unless its burning a lot of oil, then the heavier oil will not burn as fast. The synthetic is supposedly better, may be but more than $1.75 per quart is too much for me. I feel confident that the above mentioned oil and oil change schedule will and has taken my vehicles over 200,000+ miles w/ no engine problems or excessive wear. I'm sure that there are many opinions on this subject, just do a search on this topic on this webpage.

i recently stopped letting the dealer do my oil changes, and put in some Castrol GTX 10w30 oil with a Purolator PureOne filter. The truck feels a lot smoother running now, not sure if its because of the oil, the filter, or both. But its better than the bulk dealer/mopar crap.

With respect to the above posts here is my 2 cents.
I used other motor oils and recently changed to AMSOIL. In my opinion AMSOIL is the best oil I have used. No i have not used all these different oils, but from my experience AMSOIL is the best. Yes $4.40 for a quart is expensive, but when I only have to change it once a year or every 25K, that in itself out weights these other oils, in regard to prive. 1.75 a quart for 3k or 4.40 for 25K. It's up to you, but it has also been proven that Synthetics are the best oil, and AMSOILS makes the best synthetics. Not to mention the more than 1 MPG increase in my milage since the change. Just my opinion, but Im sure that all of these other oils are very superior.

this motor oil or that motor oil is "the best I have ever used" none of you have the lab equipement to test this stuff out your self, not even you Steve, the best any of you can do is "Parrot" what someone else, be it a distributer like Steve that has a vested interest or a paid mouthpiece, as in the guy in the last comercial for your "favorite oil product" Until I see independent lab test results, as from Consumer's Union or Consumer's Digest, (even those are sometimes very biased) could I ever endorse a lubrication product as being better then another.
The comment about a single viscosity oil being more stable then a multi-viscosity oil is based on lack of knowledge as just the opposite is true, as the single viscosity oil heats up it becomes thinner and thinner untill reaching water like consistancy, a multi-vis oil takes a lot more heat before thinning out. I am very glad I have never bought a used vehicle from you Vin as I could bet a teardown of that engine would reveal much more damage then you imagine.

Why do people come on here trying to start stuff? To quote myself, "In my opinion AMSOIL is the best oil I have used." Now "uh" might not be talking to me, but i take it that he is. If you read closely to what I wrote, i said "In my opinion." I also said that "No i have not used all these different oils, but from my experience AMSOIL is the best." Someone asked for opinions and I give mine. What makes Castrol GTX, or Mobil 1 better? I have used, Valvoline, Havoline, etc... and have found AMSOIL to be the best for me. I also posted some other facts that I have come across. $1.40 a quart for 3k changes or $4.40 for 1 year 25k changes. Do the math and it's better right there. I am also getting better mileage with AMSOIL over the other oils i have used. I don't need to have all this tested to prove my Opinion. Now for the other things stated, that is a different story, just backing myself up, and providing my opinion and my own results so far. Try to duplicate test results in a street car and it's hard, but listening to stories about those that use the product, that might be a little more helpful.

| Motor Oil Viscosity = Amsoil - Amzoil Dodge Dakota
IP: Logged
Message:
All metal engine parts need to be separated from each other while moving in order to prevent friction and wear on the parts. This in done in modern production engines using a thin film of oil (usually less than 1/10,000 of an inch thick). Oil’s viscosity, in part, determines how thick a film the oil will form between moving parts, and how much friction there will be between those parts when separated by the oil.
Higher viscosity means thicker oil films and more friction within the oil. Obviously, one wants a viscosity high enough to prevent parts from grinding against each other, but no higher than that, because any more results in excessive friction within the oil, leading to excess heat and power loss. The ideal oil would provide the minimum required viscosity under all conditions.
Unfortunately, an oil’s viscosity diminishes with increasing temperature, necessitating the use of an oil which will have the minimum required viscosity at the highest expected temperature, and greater than optimal viscosity at lower temperatures.
__________________________________________________
VISCOSITY ... in the general term is defined as " a fluids resistance to flow". it's a measure of the internal friction of the fluid or the resistance to the movement of one layer of molecules relative to an adjacent layer.
THE LOWER (SMALLER or FIRST #, as in "10w-_) NUMBER.. is the Cold Cranking measurement, made at low temperatures, using a concentric cylinder viscometer to predict the oils cranking resistance in an engine during cold starting.
The measuring devices, or viscosmeters, most often used are in the form of close-fitting concentric cylinders. The fluid being evaluated is placed between the cylinder walls, the outer cylinder is held stationary and the inner cylinder is rotated. The speed of rotation is measured for a given force to calculate the viscosity, most commonly reported in cp or centipoise units. Also known as Absolute Viscosity.
THE HIGHER (BIGGER or SECOND #, as in "-30") NUMBER...is commonly measured in capilary tubes, in which the time for a fixed volume of fluid to flow through the tube under gravity at operating temp (100c)is measured and reported as cSt or centistokes. This is used most commonly to report the normal operating viscosity of motor oils or the higher number.
The second number represents the oil’s high-temperature viscosity, but higher is not always better! One wants to choose the minimum viscosity that results in an oil film thick enough to prevent wear at the temperatures one expects to encounter. Only the engineers that designed the engine know what viscosity is required to provide adequate film thickness without unnecessary friction, so you should certainly try to remain within manufacturers guidelines. For what it’s worth, I trust the engineers.
It is almost certain that higher viscosity oils, such as Xw-40 and Xw-50, are complete wastes of energy, placing undue strain on your engine, and raising operating temperatures for no real benefit.
__________________________________________________
" _x_W- " is a viscosity GRADE, not a viscosity MEASUREMENT.
When testing for cold fluidity, the temperature is lowered approximately 5 degrees centigrade between each test.
The Cold Crank Simulator Apparent Viscosity is tested at:
-20 C for 10W-
-25 C fpr 5W-
-30 C for 0W-
It is my understanding that the oil has to be labelled at the lowest temperature it meets the specifications.
It may not be long before someone comes out with a " -5W-30 " which would correspond with -35 C.

| Amsoil - Castrol - PureOne - Amzoil Synthetic Oil
IP: Logged
Message:
mhall02, FYI ...
If you are looking for a GOOD on-the-shelf motor oil use Mobil1 and not Castrol. Castrol is NOT a true 100% synthetic oil. Castrol Syntec is NOT a REAL synthetic ... it is a Group III hydrocracked (dino) crude oil with some Group IV synthetic blended in. The Castrol is a "PRETEND" synthetic. Conversely, Mobil1 IS a TRUE synthetic. Only oils manufactured with Group IV and Group V base oils are TRUE Synthetics.
Now let me state that Amsoil is a better oil --- with better base oils and additive packages.
Amsoil is formulated for extended drain. You can extend your drain intervals up to 2 - 3 times manufacturers recommendations. NO ... I am not crazy. Redline recently published a report acknowledging that "some" synthetic oils are capable of 25,000 mile oil change intervals, but they do not recommend it with their oils. Too bad they did not mention that Amsoil is capable of 25,000 mile oil changes (with oil analysis), but of course they did not want to mention the name of their competition.

Oil Filters and your choice of PureOne
Your filter choice? I've got issues with restricted flow in the PureOne because of the densely packed media (keep reading for further information).
YOU NEED A BALANCE BETWEEN --- FILTRATION and FLOW
FILTRATION
It seems that engine wear gets worse when there are particles above 5 micron particles not being filtered out of the system. GM has done studies where the wear became very great at around 30 microns. On the flip-side, Mobil did tests in 1995 where they ran a number of vehicles at 7.5K oil changes and 15K oil changes on filters that would have been in the 25 micron range. The vehicles went 200K with very little wear. So it would seem that filters that grab most of the 15-20 micron particles whould be OK. I know this is not very scientific.
It really depends on the clearances in your engine. An engine such as my neighbors LT1, which is a small block Chevy as far as the bottom end is concerned, has large clearances so a 20 micron particle won't harm it as much as it would on a much tighter engine such as many DOHC 4 cylinder imports. So in other words, it's different in every case.
--------------------------------------------------
In theory, reducing wear particles to 0 is optimum but in the real world of automobile engines it doesn't work.
What good does filtering out for instance .5 (1/2) microns ... 100% of the time ... but causing wear by interupting oil flow to the bearings.
--------------------------------------------------
If you are concerned, perform a Used Oil Analysis and see for yourself what is the PPM range in your engine ... for all the major metals (iron, lead, alumn, copper).
--------------------------------------------------
FLOW
FLOW IS ... AS IMPORTANT, maybe ... MORE IMPORTANT ... than FILTRATION. Many filters have good filtration and terrible flow.
__________________________________________________
Now, Let's talk about the different manufacturers:
Here is what is out there:
Honeywell - makes Fram (In Canada the Quaker State filters are Fram filters / In the USA, QS is Purolator), Pennzoil, Quaker State
Arvin Meritor - makes Purolator Premium Plus, PureONE, Ford OEM, V-1 & SureFlow (Superflow?)
Dana - makes Wix and Napa Gold/Silver, AC Delco DuraGuards for Canada
Baldwin (Parent of Hastings) - Baldwin, Hastings, Amsoil, Casite, maybe others
Champion Labs - Mobil 1, K&N, Supertech, AC Delco DuraGuards (two different types) for USA, Bosch Premium, STP, Ultraguard Gold, Deutch & Luberfiner
Cummins Engine - owns Fleetguard
Mann - a top quality German filter maker (for our many German Friends on this site).
__________________________________________________
Considering a combination of FILTRATION and FLOW ...
Perhaps the best $5 filter, Bosch Super Premium or Wix. Reasons: Top notch construction, good filtering, and good flow. (The PureOne is in this price range too, but I've got issues with restricted flow in the PureOne because of the densely packed media.)
And if your budget is $7, Amsoil SDF oil filters.

Consumers Reports ran a test several years ago, using about a dozen New York City cabs.
They tested synthetics and several of the popular additives along with most of the off the shelf oils for 100,000 miles.
They tore the engines down at the end of the test and measured various parts for wear and came to the conclusion that any good brand name oil was as good as any synthetic and that the additives were worthless.

| Amsoil Micron vs. Beta Testing = Amzoil
IP: Logged
Message:
First let me address Relf,
Micron Rating vs. Beta Rating
Q. What is the difference between a "micron rating" and a "beta ratio test" when referring to filters?
A. Micron Ratings are arbitrary values assigned to filters or media. Although a "micron" is a length (1 millionth of a meter), a "micron rating" is not actually a measured value. The micron rating for a filter quotes a particle size without establishing the filter's efficiency at removing that size of particles. A window screen will remove some 1 micron particles, but it will not be very efficient. Since a micron rating cannot be verified, filter manufacturers are safe in assigning any number that they want. AMSOIL does not recommend comparing filters based on micron ratings.
To compare filters, the filter industry has established standardized tests for measuring performance. These tests include Life and Efficiency Tests (SAE J726, J806, and J905) and Beta Ratio Tests (SAE J1858). These SAE standardized test methods, along with the meticulous recording of test conditions, ensure that filter comparisons are "apples to apples."
Life and Efficiency Tests measure the filter's ability to remove a standardized contaminant from a standardized fluid that is flowing at a constant rate and a constant temperature. The test continues until the contamination trapped in the media raises the differential pressure drop across the filter to a specific, predetermined level. Life and Efficiency Test results will include a Time Weighted Efficiency (%) and a Capacity (grams).
Beta Ratio Tests are by far the most accurate and objective way to compare the performance of filters. A Beta Ratio Test measures a filter's ability to remove particles of given sizes. In other words, the test measures the filter's efficiencies at specific particle sizes. The beta ratio test equipment actually counts the particles in the fluid before the filter and after the filter.

| Amsoil Consumer Reports NYC Taxi Oil Test
IP: Logged
Message:
boomer47,
1) Do not forget that I live in Manhattan (NYC)
2) Therefore, I have read that CR Report
3) That test was is at least 10-15 years old
4) The test stopped at only 60k miles
5) The test did not include any synthetic oils
6) It was an "eye-ball" test, none of it with lab analysis
5) Driving habits of cabbies do not represent all types of driving habits
NYC Taxi Cabs may be driven under fairly harsh conditions, but the worst conditions of all is a vehicle driven only a few miles to and from work, often in cold weather, with the engine not warmed up. Cold starts are one of the major causes of engine wear. The CR test almost eliminated cold starts --- they kept those taxis in service constantly. So, they eliminated the major cause of wear.
A real world test would be more informative. You would need to test a fleet of different vehicles (cars, trucks, vans, SUVs) under different driving conditions. Taxi's are built to the same specifications as Police cars and Taxi's are purpose built = larger radiators, engine oil coolers, and transmission coolers that give them inherent advantages. A better test would have been to use cars regularly available to the public withouth these enhancements.
Maybe if you trade your Dakota at 60k miles of service you wouldn't care much. Problem is the truck would sure run better and use less fuel in that 60K interval if using a better quality oil and filter, and how were those same taxi's holding up after 100k, 200k, or 300k miles?
