Review of Schaeffer Oil
I must say that I am impressed with the results of changing the oil to the Schaeffer Supreme 7000 series.
First off,
The cold start knock in the top end of the engine is gone.....(common w/5.4 3v engine.)
2nd,
After two tanks,gas mileage has gone up 1.467 mpg,I am not changing the way I drive at all.
3rd,
This might be the placebo effect,but it seems to be idling smoother.
I will post a UOA up after I get about 4k for miles racked up on it.

At the rate I am driving I am going to do a UOA in June.
So far I have been very happy with it.The cold start knock that comes from the cam phasers has not been apparent since the switch to this oil as well.

I used 5w20,the same viscosity that came in the truck from the factory.
