Engine Oil

Marketing at its finest, yet you are comparing two companies that basically live off their name, one of which wasn't even able to get the proper certifications for half of its product line. Just saying.

Coming from the guy who works at a competing oil change shop?

Say what you want. But any company that fakes an API seal because they can't actually get one shouldn't be given a seat at the table in this discussion. GTFO Amsoil.

Also, yes I do realize I am coming from a competitor stand point, however on the quick lube side we are not in any real competition with Mobil 1 up here. We are more worried about making Jiffy Lube and Pennzoil look like shit bags.

Where the F did this 3000 mile mark come from? i remember seeing multiple places that the oil doesnt reach its full potential until around 4000 miles. then it starts to drop. Hence why most car manufactureres now recommend 5000 mile changes.

Majority of what I've heard over on BITOG about Pennzoil Platinum Synthetic oils is that it's supposidely pretty decent.

If someones bored, It would be fun to see what those blackwater tests show for different oils.

Stop thinking about war/politics.

I get my oil tested at watergate every 6 months.

I wish they had zinc/phos specs listed for Castrol Syntec 10w-40 since that's what I put in last May on the dyno. I've only driven the car a couple thousand miles since then, I'll probably change it again in spring just for giggles. I think 20w-50 might be a bit much for my car, though according to FP I have a race engine since I make 100bhp/liter lol.

They actually said anything that makes 100hp per piston is in race engine territory.
