not trying to stir the :stirthepot: pot i use M1 and M1 filter....

i could be wrong but i think GM was one of the first manufactures to use m1
in the corvette motors. so good enough for me.

yes but ferarri use Pennzoil!! bwahahahaahha :stirthepot:

Pot has been sufficiently stirred.

I just would not run to 8K OP, 5k max

Think so? You might want to read this: Don't use Nissan OEM oil filters

BTW, where are you getting your M1?

What about Rotella T Synthetic? I used to run that in all my cars when I found out about it. The price is decent (Walmart) and its mainly designed to be cleaner for use in Diesel trucks. Lots of tq and boost out of those engines...

I have not used it in years, for no good reason though.

A great oil! Very tough, and meets just about every specification possible for auto manufacturers. I run it in my WRX. High specific output engines love this oil.

Negative. In oils, the "x" in xw-y, is the weight of the oil when cold. There is some variation in this category, but for the most part, a 5w-30 oil is as thick when cold as a 5w-40. If your talking about viscosity when hot, then yes, the 5w-40 will be a bit thicker than the 5w-30.

Ferrari uses Pennzoil Ultra European, there is a difference.

On the contrary isn't Rotella one of the oils that specifically does Not meet the new standards calling for less zinc in the oil to meet reduced emissions regulations.

That is of course why people like it since the zinc is what protects your motor, but it's also supposedly rotting out your cat's and killing us all :rofl2:

I wish Rotella T Synth was part of the above oil testings. Im sure I could find a wear test for it though.

Yea it doesnt meet emissions reqs for standard passenger vehicles with emmissions controls. Diesel engines have much different standards, and much different stress/tollerances. its not easy making ~1000 lb/tq at the wheels.

That test, as any other test, could be easily challenged... This said, it is self-explanatory!

Also, and i speak with experience using RP oils, i never had any issues or bad oil analysis reports using RP for the 370.

The only suggestion would be to wait for at least 5k of breaking before starting using Royal Purple.

ps. I "love" theese oil threads...

I Know, i know...lol

Personal Favorite is Eneos Oil
