..my mechanic said, "engine was spotless and not one tiny bit of sludge whatsoever".

Wish I had a picture I could share...nothing but Pennzoile, Valvoline and Valvoline Maxlife.

1995 Chev Lumina 3.1L w/144k

Thats not surprising, cause Pennzoil and Valvoline are both great oils.

Not a surprise at all....

Once you get the intake gasket problem solved, 3.1s are great engines. Its my understanding they are easy on oil, too.

Keep using whatever oil brand you prefer, Ill see you on the road....

My '97 GPGT had 308,000 miles on it,all on Havoline 10W30, when I did the upper and lower intake gasket job. Mine looked great and now has 352,000 miles on it and it still runs great, gets 25-28 mpg on the road, and uses no appreciable amount of oil.
