[87BOSS351C]

I use Quaker State in everything. That's what the 302 in my Torino has used since it was new. When I put in new lifters and gaskets at about 78,000 miles the bearings still looked like new and you coudn't even feel any sign of a ring ridge in the cylinders. I was really impressed with the lack of any sludge build up in the engine. In that car it's straight 30w. That is also what I have in the 351C for break in, but that will change to Mobil 1 5w30 synthetic afterwards. On both I run the Motorcraft filter, but the Cleveland will get the HP version after break in. I ran QS 10w30 in an old s-10 blazer I had with 100,000 miles on it. With 3000 miles on an oil change, the oil still looked like you had just poured it out of the bottle.

Honestly though, I really doubt a specific brand of oil is any better than another. All non-syns start from the same place - in the ground.

Why is everyone so Anti-Fram filters? I've run them now and then (when on sale) on non Fords and never had any problems. On my Fords I always run the Motorcraft cause it looks better. Just wondering.
