"I've found a good source of information:
www.bobistheoilguy.com"
Yep. Good site. I've been a member since 2002 ... I'm #20 and they are now well over 5,000 registered members.
"Great information about what oils to use and what to avoid. Summary:
Amsoil is good, but seems to break down over time."
Um, I don't think so. Amsoil is one of the most stable of passenger car motor oils ... and seems to be the best suited for extended drains ... but I don't use it personally.
"Red Line and Royal Purple are excellent synthetics"
Both have their issues that bother many of us BITOGers: Red Line's chemisrty seems a bit 'aggressive' for a lot of engines and it appears to chemically scoure the motor and pick up a lot of metal which shows up on UOAs.
Royal Purple's street grades thin out like no other oil I've seen, conventional or synthetic.
"Mobil One is a good oil, but not up to par with other synthetics like those listed."
Well, their 0W-30 and 0W-40 shear down quickly, and they tend to start off a little on the thin side, but I'd say the current formulation is very good. Past formulations (SJ TriSynthetic, for example) were poor choices.
"Castrol Syntec = crap"
Actually, a decent oil ... but not worth the $4+ per quart retail. It's a Group III oil and not a 'true' synthetic like Mobil 1, Red Line, Amsoil and a few others. A lot of us are pretty miffed at Castrol for starting this whole "Group III mineral oil = synthetic sham" back in 1997.
Actually, there are a handful of really good motor oil threads on this forum. I've participated in many. Try searching using brand names of oil like "Pennzoil," "Castrol," "Chevron" or the word "synthetic" to bring them up.
