While I realize this Isn't a major issue, I was told by several people that running 15w40 diesel oil may solve the problem, some having done so themselves. Will this thicker oil hurt my engine? I wasn't planning on running that oil during the winters due to the very cold conditions I sometimes need to run the truck in (about -10 below) , but would it be that bad of an idea to try during the summer? Just looking for some input. Thanks, NHD
First of all
3000 miles you burn
UNDER a quart of oil for a TRUCK engine with 180,000 miles?
What was the problem? Answer NOTHING.
Continue with what you've been doing.
No NEED to change a THING.
Winter time I'd use Pennzoil conventional 5w-30 and 10w-30 the rest of the time.
Take care, bill
Leave it to Bill to put this all into a nutshell. He's right. I'd be pretty thrilled to have an engine with almost 200K miles that used "only" a quart in 3000 miles.
