Asked by Feb 09, 2017 at 09:33 AM about the 1996 GMC Sierra 1500 K1500 SLT 4WD Extended Cab LB

Question type: Maintenance & Repair

My 350 engine has got gas in the oil I
think. Could it be from a low viscosity oil or
bad injector?

It could be by the way it is running, but the check engine light would come on indicating a problem.

The light isn't on but the oil on my dipstick is getting higher up

Then you have a blown head gasket.

By chance do you live in Washington State? I knew a John Roberts out there...

If the oil smells of gasoline and the level is increasing a fuel injector that is leaking is the likely cause. This will not cause the oil in the engine to look any different. A blown head gasket that is leaking coolant into the oil will make the oil look much like chocolate milk.
