GM To Spec 20 weight motor oil

[Sarge]

for its cars in 2009. CAFE sucks that ass! So you got a firebreathing 09 Camaro with a LS2. Gonna run 0-20 weight oil in it?
Let the battle begin!!!!!!!

[SeVeReDiStOrTiOn]

Is it because of the cylinder deactivation thing?

[Sarge]

No...because of CAFE and fuel mileage.

[pecha]

what's CAFE?

[JonB]

what's CAFE?

What is CAFE?
Corporate Average Fuel Economy (CAFE) is the sales weighted average fuel economy, expressed in miles per gallon (mpg), of a manufacturer’s fleet of passenger cars or light trucks with a gross vehicle weight rating (GVWR) of 8,500 lbs. or less, manufactured for sale in the United States, for any given model year. Fuel economy is defined as the average mileage traveled by an automobile per gallon of gasoline (or equivalent amount of other fuel) consumed as measured in accordance with the testing and evaluation protocol set forth by the Environmental Protection Agency (EPA).

So do you think this will affect the life of the motor? not to sound stupid, But I know your the OIL GURU around here

[Sarge]

Yup. Ford sold out.All the manufacturer wants is CAFE MPG and you to get through the warranty period.

so i'm confused as to what all this means

[INMY01TA]

I'd run a 30 weight anyway.

20W is a thinner oil... makes things spin eaiser, so there is less parasitic loss, so, better MPG. Like...... VERY VERY slightly better... however, there is a drawback... going that low will likely promote wear inside the engine, and increase oil consumption.

So, basicly, the automakers are scrambling for every MPG advantage they can, because the government are overcontrolling assholes.



that about sum it up for ya?

yeah...that's kinda what i was thinkin was goin on but i was sure. so what are they going to do about decreased engine life expectancy? nothing?

Sarge, my dads hemi ram calls for 5-20. Should he continue to use that or switch? If so what?

[blackhawk01]

i dont me to be a dumbass but..its about time for an oil change and this is my first LS1...what oil do I need to put in it im at 72k miles

I'd tell my Dad to run a UOA and look at the wear metals. Track his MPG. Then switch to a 5-30 and do the same thing. That will cut through the shit so to speak. Here UOA's are cheap as hell.....

With knowing absolutely nothing about your modifications nor driving habits...Pennzoil Platinum 10-30 is good for most LS1 applications.

well..the only time I race is street race sometimes..and thats not that often unless i get a good open stretch of road with no cars. I get in it ocassionally.

im not certain if the hemi in the trucks has it, but on the 300c/charger platform the hemi has cylinder deactivation, and the engine has to use the 5w20 to operate right. When I worked at the Ford/Chrysler shop, they were actually getting hemi engines with problems because of people using the wrong oil. I dont know all the technical specifics of the situation to tell you guys but I do know that that particular engine calls for specifically 5w20. As far as these new gm engines or the ford engines etc. Jus put in what you want basically.

well its always running on all 8 so im pretty sure it doesnt have cylinder deactivation. So I dunno...i just dont want him to run 5-20 because dodge says so just so they can claim a few more mpg and have the engine die on him down the road.

understandable. dont rely on EVERYTHING the manufacturer always says.
