Message:
I just bought a 1999 dakota sport yellow ex cab v8 with 24k
miles (from from a female). never off road,never
pulled a trailer,it looks new. Question is her boyfriend works on cars,trucks, ect. for a living
and has since 1980, he has been to many lube schools and has run 20/50 valveoline in all his
wheels, he has this in the dakota, the book says
10/30 weight,he says the 20/50 is a better grade of oil. what do ya think....????

|  Viscosity 10w-30 or 20w-50 = Amsoil Synthetic Oil

Absolutely the 10w-30.
All you will accomplish running the 20w-50
... is more visits to the gasoline pump.
Also, use something besides Valvoline.
Valvoline is Group III Hydrocracked Conventional Petroleum (Dino) and is not a true synthetic oil. Plus, Valvoline's additive package is pretty weak.

Viscosity
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.
--------------------------------------------------
Viscosity:
" 0w- " 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.
--------------------------------------------------
In closing:
The API rating of an oil is actually a translation of the technical jargon of the American Society of Testing and Materials (ASTM) and the Society of Automotive Engineers (SAE). The SAE rating reflects how the oil will flow at particular temperature. A 5W-30 protects like a 5 weight oil when cold and protects like a 30 weight oil when hot. A straight 30 weight oil is not supposed to change viscosity so it will protect and flow like a 30 weight cold or hot. With the test results from the ASTM and the SAE rating, the API then rates the oil.
We should use an oil that protects us between the temperature range we live in. Using a 5w-30 or 10w-30 oil will generally give you 1-3% better gas mileage than a 30 weight or 20-50 weight oil. Thinner is better, both for your engine and your pocketbook.
I know that putting a thinner oil in your car goes against everything you have been taught. Most of us cringe at the thought of putting a 5w-30 in our engine. First, you must understand what motor oil is supposed to do.
What a Motor Oil is Supposed to do:
1. Oil is used to provide lubrication between two moving parts to reduce wear. Most internal engine tolerances are measured in thousandths of an inch and many tolerances are no thicker than a human hair.
2. Oil is used to gather or absorb heat from the internal engine parts and carry it away. If we want to flush this joint (tiny tolerance) with oil and keep a continuous stream of oil running through and over it to gather the heat generated and carry it away, would you use thick oil or thin oil?
3. Oil is also used to flush the metal particles from the bearings of your engine.
4. 90-95% of all mechanical engine wear occurs in the first 10 seconds of a cold engine start up. That initial cold start wear can equal hundreds of miles of warm engine wear. Therefore, pick a Xw- oil that corresponds with where you live and drive.
Disclaimer: There are situations that call for a thicker oil. In the event your car consumes an abnormal amount of oil between oil changes, using a thicker oil might be beneficial. A thicker oil might help you control the oil consumption ... but it is really just masking a more serious problem.
Keep in mind that almost every car manufactured since 1993 recommends a 5w-30 or a 10w-30. We must work to overcome the idea that thicker is better unless of course there is a reason.

Many have asked: Is Amsoil approved by Dodge?
DODGE DEALERSHIPS NOW CARRY AMSOIL !!!
This was posted by Sephiroth 3/20/2004
V8 Forum --- Subject: New Chrysler Product?!
Message posted by Sephiroth:
"I went in to have my brakes checked today, and when I walked into the garage the first thing I saw made my jaw hit the floor. My local dealership now uses and sells AMSOIL products!! They've got it posted on a big banner over the service-desks. GM may not have been able to get it for their 'vettes, but obviously Dodge was able to, or they found out how awesome it is and started buying at regular price! When I go in for a tranny-filter, fluid, and gasket change next week, it's getting filled with AMS."
Sephiroth went on to state:
"This is at the Raleigh, NC dealership, Al Smith Buick, Dodge, Mazda. I told the guy at the desk I was astounded to see them using AMS and that I had been using it for a while now. After he rode in the truck he said he'd be switching next oil-change in his Ram.
As for me, I've got it in the engine, and I'll have it in the tranny soon! Next up are the differentials. After that I need to get a dyno just for curiosity's sake. IF I get 3-5hp form the differential, and God knows how much from the engine and tranny, that'll be enough without any heavy mods. Well, for all I do anyway. If it is a significant gain, I'll post the results."

"Norwood (MA) Dodge sells Amsoil too."
__________________________________________________
Dodge Dealerships are beginning to realize that Amsoil offers a FULL LINE of Premium Synthetic Lubricants and Dodge Dealerships are beginning to offer Amsoil.
Why ...
1) Dodge knows Amsoil meets AND exceeds Dodge's requirements.
2) Because their customers are asking for Amsoil.
3) Amsoil = 30 Year History of Research and Development
4) Amsoil offers the best Synthetic Lubricants

Steve tends to get a bit windy sometimes, but you have to forgive him, oil is his passion and he knows his stuff. To translate his post, a thicker oil will just decrease mileage and waste money. Especially on a truck with that low mileage. If you had 124k, the thicker oil may help reduce burning oil due to worn rings. 10W30 all the way, and do your engine a favor make it synthetic 10W30.
