Engine Performance problem
2002 GMC Sierra V8 Four Wheel Drive Automatic 166000 miles
Forgive my ignorance on this, having trouble with my maintenance. All of a sudden, the oil in my oilpan is "milky" or rather like cottage cheese. I have no idea what causes this and would like to have a little "intelligence" before I have to deal with someone to fix this. I have a Z71 GMC '02 with 166,000 miles. The truck runs absolutely perfect other than I have lost mileage on a full tank, roughly about 50 miles per full tank(used to get 400 miles on a fulltank, now 350 or less) No loss of power or anything. Can someone offer me any suggestions as to what might cause this?
have the same problem?
