Red Line 0W-XX MRV spec's

[CATERHAM]

Since we're in the middle of a heat wave right now I thought it would be a good time to get Red Line MRV spec's @-40 degrees:

0W-20 .....27,000cP
0W-30 .....28,000cP
0W-40 .....30,000cP

Hey Caterham, what's MRV? Why should I care?

 

[CATERHAM]

No you shouldn't care, not even in a Chicago winter.

They are quite high, especially for 0W-xx oil.

Every oil data I had gathered are below 20.000.

Do you know why they are so high? Is it because they are ester based?

 

[Samilcar]

I've seen a lot of MRV specs given at -30 and -35°C, but I don't think I've ever seen values given for -40°C.

Was thinking the same thing, they aren't actually that good at all.

Not that you will ever REALLY need them, but still, for and all-ester 0W, I'd expect better - Petro-Canada, Pennzoil, and Kendall all best these with the use of group-III base oils.

0W oils MRV test is done at -40C, as the cranking test is done at -35C.

In comparison:

M1 0W40 has MRV of 31,000 at -40C, slightly higher than Redline

M1 0W30 AFE has MRV of 13,250 at -40C, a lot lower than Redline

M1 0W20 AFE has MRV of 9200 at -40C, a lot lower than Redline

The M1 0W-20 MRV is amazing.

Interesting, I don't think I've ever seen any MRV numbers for Red Line oil, only CCS. Did you get them from Dave?

 

[CATERHAM]

I don't think anybody buys RL for it's extreme cold performance. The main advantage of it's POE based formulation is high temp' stability.

What I find interesting is the limited difference between the three grades comparied to most oils like M1 for example. I suspect the only difference between the three oils is their VII content, which is none for the 0W-20, very little for the 0W-30 and the most in the 0W-40.

Yep from Dave.
As a point of interest, 21Rouge got the MRV spec' for the 0W-30 last fall and was told it was 30,000cP, consiquently I was expecting the 0W-40 to be much higher.

 

[JeremyInMT]

Interesting. I'd been very curious about these. M1, like you have told me earlier, really spanks them here. I'm curious of the curve as it goes from -40 to 0 to +40.

 

[SubLGT]

Anybody have the MRV specs for the Pennzoil Platinum lineup? Pennzoil still does not have PDSs available at their website.

 

[addyguy]

I think the 0W-20 is 14,800.

IMO, Redline 0W-xx is meant for car that need less HTHS to run optimally but not really to take care of cold weather.
