I went to GMdieseltech.com and found two oils....I just don't know the difference between the two....one is Schaeffers 15w-40 Supreme ..... and the other is Full Synthetic 5W-40 from Schaeffers. Which one do I want?? There is only a 2.00 price difference.

Last time I got everything from a Auto Parts Store around here...I ended up paying 98.00 to change my oil. And that was just oil and oil filter. Diesel parts are expensive around here....and noone knows anything about them.
