I have noticed that sometimes when I go 4 wheeling that my Blazer uses about 1/2 court of oil sometimes more. I only have 40k on a new motor from the factory. Is this common??? If not what could be wrong??
no markings, the plugs are kinda sooty but I had a problem with the cat and 02 sencer and the shop said that that the plugs would get some build up on them from the computer messing up the mixture. There is no sloke comming out the exhaust either! I lost!!!! Time for me to go tto school for this crap!
