More PAO, less POE. ?

Most oils use very little ester. Maybe 10% max in most major top tier oils. I'd guess RL is using significantly higher POE content.
 
Do you guys have any ideas what this means? Just curious. It's still my primary oil regardless.

I only use the 5W20 and 5W30. Im about to stock up on those.

If I was gonna buy Red Line....these are the two oils I'd stay away from.

I'd mix the 0w20, 0w30, and especially the 0w40 to meet the viscosities that I would require. The 5w20 is YUCKY!! At least compared to the rest. Blahhhh....oh, I think I just puked a little bit. LOL!!
 
These are new values posted on their website.
In general the KV's are higher, and the HTHS's are lower. This makes RedLine oils look more like everybody else's.

I will be curious to see if they perform any better. For the $, RL has not been that impressive of an oil compared to the competition.
 
Yes thanks for the RL updates.
It's just recent as I checked the spec's on some of their oils last week and hey we're up-dated yet.

This is the first major up-date in years although a member had the HTHSV of their 0W-20 independently tested a couple of years ago and it came in at 3.0cP. Anyway with a revised HTHSV of 2.9cP and a KV100 of 9.1cSt, this oil is as close to being a 30wt as you can get and since it is VII free and therefore shear proof it's better thought of as a 30wt oil.

Yes there is something wrong with the 0W-30 spec's, I suspect the KV40 value should be 63.5cSt not 69cSt.

Too bad their 0W-40 VI has dropped from 197 to 190.

We could email Dave at RL but I doubt their formulations have changed all that much, it just a normal variation you get from batch to batch particularly from a small formulator.
 
I already got an e-mail from them and they say they did some chemistry tweaks and it results in small variances in HTHS, flash, etc

I for one like the mainstream move.
Something had to be done for the 0W20, 5W20, 10W30, 10W60 as they were too off for their grade and don't think they sold too well. I also like the more human HTHS on the 5W40 along with the better flash point on 0W40- good trade there since that turned off many people that din't read Noack. Very interesting the 10W30 new approach since it should be very close to the 5W30 at operating temps.

I don't think this is a move to PAO. More VI maybe.
I see it as a different base...thinner, better flash, still ester... may be diester since that usually runs a better flash and a lower HTHS.
Seems they are switching to it for all grades. I suspect they'll make more changes to the numbers in the near future.

Good points and thanks for sharing that. I called Dave as well and he said what you did.

This isn't some batch variation. They clearly made formulation changes. Let's see what it looks like on paper. Maybe some additive treat rate differences?

Still more RL bashing?
RL is more impressive than most oils.
In particular their 0W range is top notch - shear stable, high VIs with the usual high AW additive levels; what's not to like.
 
Looks like 0W30's VI is 166, at least that is what is on the site now. Sad, that seems significantly lower than the 183 it was before, which made that a pretty cool oil IMHO.
