What oil?

Not recommended for stock obviously, but Valvoline VR1 Racing 20w50 full synthetic.

Here's a JPEG conversion of my 10W-60 synthetic oil Excel spreadsheet with manufacturer published test numbers for as many synthetic oils as I could track down. I hope this helps. I'm happy to e-mail the Excel sheet to anyone.

Many engines have spun bearings while using Castrol so I'm not sure what your point is.

I stated my point clearly and you quoted it.

It's kinda stupid to design oil around additives but hey, people like adding additives for piece of mind when they can just buy good oil.
I should've said "better" to be less absolute. It's all trash we must sift through. What makes an oil better would be the MOS2 included in the base oil without the additives. Everything else is pretty much the same. I believe it makes it more shear resistant and is just a lubricant that sticks to the metal surfaces. I don't claim to be an expert, I'm just a oil keyboard warrior with an opinion.
Seriously though, I'm done with Liquimoly. It wasn't all the oil's fault I had a piston exploded into at least 100 pieces, but it just left a bad taste in my mouth. I also used Ceratec. Still went boom. I'm sure my car will be fine without it. I didn't notice any smooth coating on anything and it was in there for 5,000 miles. I'm just not a believer. They have really good marketing. They have a potent engine flush.

Liquimoly is just trash oil. My engine DID spin a bearing while using it. Ceratec probably doesn't work very well either. It's kinda stupid to design oil around additves but hey, people like adding additives for piece of mind when they can just buy good oil.

Amsoil wins? Who da thunk it... Penzoil/Twin Power had a respectable showing. Motul and Liqui Moly, not such a good showing, at least when it comes to 5w-30 weight oil specifically. Though 5w-30 is not 10w-60 oil, I would say this is at the very least, it’s a window, or indicator on how a manufacturer’s oil will perform on a different grade oil. For me, I’ll stick with what the BMW Parts Dept. sells over the counter.

And Pennzoil = Shell

Well I wouldn't use shell so I'm good there.

I'm under the impression this Ravenol is more of a track oriented oil. That's kind of how it's marketed.

Found this guy on who tests pretty much every oil ever made. Ravenol 10w-60 performed exceptionally well. His spreadsheets listed under the video are pretty interesting.

There ya guys go. Ravenol 10w-60 spec. I couldn't type anything else in the post because of the way it transferred.

Currently using Ravenol 10W-60, so far its been great. Oil temps at the track are very reasonable!
