My wife now drives round trip for two miles in her commute. Average speed 30 mph.
On a 1996 GMC with 215k miles and 5.7 350 engine. New water pump and radiator.
My question: do I change from the usual Smittys 5w30 HM and occasional Pennz HM?
Or switch back to Mobil that I first used a few years ago?
I should also mention that she generally warms up the truck only for 10 seconds in the morning...although I tell her to warm it up at least 30-60 seconds.
Also, she does not speed to work.
