Re: Inconsistent oil pressure 98 Silverado
The construction company I work for uses straight 30w in their Chevy trucks and change the oil every 3000 miles. They consistently get 300,000+ miles out of them with the original motor. If you make a lot of short trips from a cold start you may be better off with the 10w30.
I wouldn't worry about the 32 psi, but that's just my opinion.
