I've switched away from Mobil1 as well and am now running Pennzoil Platinum as I've seen quite a few blackstone sheets like yours after running Mobil1.
Not all group III base stock oil's are bad. There are quite a few that are great, it just really depends on how they're refined and what additives are added to the oil.I don't use it anymore. That's what you'll get for using a group III oil.
U use synthetic? what weight?I love rotella t in all my turbo cars. It holds up a lot better than other oils in its price range.
What weight and do you run? synthetic or conv? People please include that info, thanks a lot!That's awesome, Rotella T is what I run. I've had some guys laugh, "That's truck oil".
Nice Moly number on the Shell. Good shit.
RP for the win!This interesting I will need to start looking at more info and possibly a new oil brand.... Royal purple maybe?? I was thinking of throwing in some 10w40 RP.... should be better than Mobil1 I am going to stop wasting money, They need to get their shit together!
I dont even see that the have synthetic? in 15w40???I run the 15-40 non-synthetic.
I use Castrol Edge 10W60 in my stockish vr4.
Anybody knows bad things bout castrol?
The rest of your post was decent so I'll just focus on the last bit. I sure hope you have more info than those little marketing graphs (and maybe the bogus Timken bearing test some Aussie magazine performed which they later retracted) to justify that statement. If you do, I'd be very interested to see it. I'm always curious about the available oils in the market.From the research I have done pretty much nothing out there beats RP related to "Film Strenght" and "Extended Life" It costs more for sure but I believe it is worth it....my 2 cents on this subject only...
