I use Havoline 10W-30 with best results! I use to use Bosch oil filters, then once or twice used AC Delco and STP - had horrible ticking sound with first couple initial starts after an oil change with both AC Delco and STP.
Gave me a bad vibe, so I switched back to Isuzu OEM filters, wish I had used them all along - truck seems to run MUCH better with higher consistent pressure.
