Mobil 1 EP, change it in all my vehicles once a year, winds up being every 10-15k miles.

Good UOAs. 5 quart jugs are cheap, and easy to get anywhere.

Never give a second though to it.

That's a rather strong statement, have anything to back it up?

I get my analysis done at Blackstone labs, look them up online.

I run mobil 1, but I am contemplating a switch to amsoil or royal purple.

Not because mobil 1 has failed me or came back with bad oil figures, but because everyone in teh performance world loves them, and I want to test the hype...

Definitely not RP. If not GC, then Amsoil. Amsoil is great. Royal Purple is severely overrated. http://www.google.com/search?hl=en&c...&aq=f&oq=&aqi=
