10w40 with 20% to 50% POE

[Wolf_Tm250]

Hello,

is there a 100% sint 10w40 oil, high HTHS ( more than 4 ) with a % of POE between 20 and 50 ?

If it's not on the market, which oils could I mix to make it ?

Thank you.

I would expect Red Line 10W-40 to fit the bill.

May I ask in what engine this oil will be used?


Red Line 10W-40

PE polyol ester base stock

Vis @ 100 degree C, cSt: 14.8
Vis @ 40 degree C, cSt: 98
Viscosity Index: 154
HTHS: 4.7
Pour Point in degree C: -45
Flash point in degree C: 248
NOACK evap loss after 1 hour @ 250 degree C: 6%

I remember, this is the Italian guy that had oil on top of his pistons. Did you get that problem solved?

 

[Wolf_Tm250]

Toyota 3SGTE ( Wolf's edition

) 2000cc. turbocharged - deeply modded - 430/435 4w hp.

Mountain roads - track use.

Italian ambient temps.

Reading other threads, it seems that Red Line has an higher percentage of POE... isn't it ?

Thank you.

According to the resident oil gurus it's essentially impossible that Red Line oil contains more than 50% ester oil.

I got Red Line 5w30 in my Audi, and so far the seals are holding.

Hi GoldenRod,

you remember correctly.

I hadn't use it again because I had to modify the oil cooler...

I'll finish it next week.

I still have to understand if it was oil ( and it seems to me that smell like oil... ) or fuel/carbon.

I removed the throttle, and I found the intake manifold to be blackish and to smell very much of fuel... it seems that I have to look at cams timing.... some reversion during the overlap ( turbine is "small" and I have some backpressure... )

Talking about oil on top of pistons, I have to say that the engine stayed at idle for 10 minutes before I removed the plugs... so that could be the cause for the oil to pass through the rings ?
It's only strange that compression values are all perfect !

Bye.

It's not uncommon for some engines to show perfect compression even with a defective oil control ring.

You're talking about Red Line 10W40 sinthetic engine oil, not of Racing Red Line oil... correct ?

Only problem for me would be to find it in Italy...
I can find easily Motul... but I asked them the PAO/POE% but I hadn't yet a reply...


Bye...

Ahhh....

do you have then any advice ?

Try 1000 miles more witha semi-synth oil to help the rings' seating ?

 

[GoldenRod]

Mori's right. You could have good compression ring tension, but not enough tension on the oil control ring. Some engines will use a back up ring that goes on to the ring groove before the oil control ring. This gives the oil control ring more tension and oil scraping ability.

I don't mean to sound like I'm hoping this is the case, but just wanted to mention it in case you have exausted all other possibilities.

I'm talking about their street oils. Red Line race oils are all straight weight:

2 WT
5 WT
10 WT
all the way up to 70 WT.

I have no idea about the oil that gets on your pistons. Your rings are probably seated just fine. I mean, with over 400 hp, how could they not be seated?

Does your oil temperature get up really high?

 

[Wolf_Tm250]

After mapping and rolling it at 700 miles, I used it in track in Varano when I had 1000 miles.

Ambient temp was of 6 deg C., and after 6 laps I reached easily 125 deg. C....

That's why I'm putting a bigger oil cooler.... italian summer is hotter... ambient temp around 40 deg C.

BTW I made only 6 laps because I cracked a weld on the ext wastegate feed runner...

motul chrono 300v double ester 100%

 

[boxcartommie22]

wolf , you aren't going to find out here it is all speculation all i can tell you is what redline and motul engineering tells you..dave said all redline is 100% poe they found away to protect seals no pao nor dino carrier oils 100% synthetic etc...motul says there motul chrono 300v is double ester 100% with nooo pao..i love both of these oils

 

[boxcartommie22]

redline's racing oils and car oils are exactly the same except car oils have detergents and the racing oils don't thats it!! they all have the same additives..zinc 1400ppm and phos 1400ppm and moly 982ppm/ per dave at redline..i believe him !!

Your posts prove that. They contain more hearsay and opinions.

 

[TallPaul]

Since Redline says they use a majority of POE in their base oil, I think it is a sure thing that Redline is at least 20% POE, and I doubt it is more than 50% for the total package (base oil and additives).

BTW, I have heard that only Redline 5w40 has VII, so though they meet the multigrade criteria, they are also, in effect, straight weights in that they have no VII.

 

[moribundman]

boxfarttommie, we agree on one thing!

ekpolk received an email from Dave at Redline stating they are 50% PAO.

I recieved an email from Dave saying they use POE as the "primary" basestock but do use some PAO. What more do you want?

The guy at Elf, Laurent Siret, said Elf's F1 oils are 80% PAO and that you can't have a 100% ester based oil nor is it desirable.

 

[boxcartommie22]

moributtman, one can post anything on here and call it proof....i find my proof for me ...not here on line..sort all that out why don't ya?..one can believe stuff on here but not actually know..alot more research is envolved but this site is awesome!!!
