E85/eflex And Oil Choice

[AngryRB]

only time my oil turns to a dark colour is after a flogging on the dyno

[ironpaw]

Just abit of my finding for anyone interested during the cold this winter, car basically spent two months in the garage with being started once a week up to operating temp and when I went to drop the oil today before the next track day this is what I found.

Oil had completly absored the e85 wasnt even oily anymore ended up like water. This is motul 4100 power, it was fine for 3 months in summer but winter guess its not up to the task for being stationary.

Oh shit...my car's been sitting around for months and hasn't been started weekly...now I have water as engine oil...great..........

I actually think that mine ended up how it was due to starting it every week and since I have an oil cooler the oil did not get up to operating temp to burn off the moisture it kept getting worse. I rekon if it sits there not being started it will probably absorb less moisture, well this is what Im trying this time.

You are thinking into it too much, just get in , warm the car up and take it for a hard drive through the hills for as long as possible. The majority of the water/ethanol will evaporate especially as you don't have an oil cooler.

As it has been sitting so long you could just drop the oil, not a hard job buddy. Go the Synx6000 this time, let me know what it's like.

Might do that tomorrow night...fancy a visit from me? LOL

I've still got 6L of Motul 300v to use...maybe I should flog that off and use some Synx6k instead?

[scotty nm35]

I was able to run 300v with no issues, perhaps because the oil temp in the VQ is up around 90 degrees... Is it SN rated though? That is what you need to look for in an oil now.

[ARTZ]

So is my 40$ penrite Scott.

The Gulf you have is SN isn't it...Really looks like edge is the go though..might have to change just so all the tuners don't laugh and say I told you so when I spin a bearing..

[scotty nm35]

I tried edge, it was way too thick for the VQ. I will be sticking with the Synx6000 ($37.50 per5L) when the Sougi 6000 runs out.

I'm not sure if you're reading his comment correctly. I'm pretty sure he said it got started and run to op temp weekly.

agreed, i have water literally spewing out of my breathers

Motul told me the 8100 was ok with E85, but 300v would only work if you did frequent changes.

See if you can flog it off on someone and switch to the Syn X?

I've been using Castrol Edge 10w60 with Ethanol for over a year now, oil comes out fine every time it's dumped with no issues. My motor probably gets leant on a lot harder than most

How long between changes? that is probably more the issue if people are leaving it 6-8 months etc.

[SiR_RB]

so a car getting used every 2nd day for atleast 40min each way trips, shouldnt realy have any issues with water condensation in the oil as it would just evaporate?

[scotty nm35]

Yep, you won't have a problem. The water/ethanol evaporates fairly quickly once it's up to operating temp.

Summer won't be bad but short drives in winter may cause issues with catch cans filling quickly, and oil going milky, depending on your oil temps.

[AngryRB]

been using mobil 1 oil for last 4000km's, still gold honey colour , i doubt my oil gets that hot either so must be good stuff..

[SiR_RB]

Great to know, I'm using a fully synthetic ester oil now so il keep an eye on it when the e85 setup is up and running

Otherwise just change to the castrol edge/ motul 6100 variety

[SiR_RB]

on a side note, what seems to be the safe power limit of 1000cc injectors on e85?

[discopotato03]

Something that could possibly be thought about is running higher temperature coolant thermostats like the R34 GTts use . From memory they are 82 instead of 76 and that could have an effect on oil temp and warm up times .

I certainly would not be using lower temp ones eg Nismos in a street car let alone an E70-E85 fueled one .

A .

[SiR_RB]

My water temp is always around 80degrees, oil temps 85-90degrees

Normal street driving and drag racing

[boxheadmr]

My understanding is the water is one issue however the main concern is greater fuel and oil mix over time?
