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.

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?

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.

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.

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.

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 .

      Why am I hitting a power wall with my stroked RB25?

      By TurboTapin · Posted

      I couldn't agree more. I should have started from the get-go with a NEO or solid bucket conversion. I started looking into converting over to solid lifters yesterday. Now for some reason I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  But I see no mention of this on any of the Tomei documentation. It just states I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!? There's no way it's that simple, I must me missing something?

      "Cheap" bolt on turbo on RB25DET NEO

      By Kapr · Posted

      @Murray_Calavera iam just considering options 🙂 of course it is very expensive so that why i ask here 🙂  @joshuaho96 I looked at that GCG hybrid(i remember looking at it few weeks before) So this is "that" hybrid where i send them my turbo and they upgrade the inside to Garrett stuff and then they send it back. It cost around 1200-1300 USD which is FAR cheaper than the HKS and it is what iam looking for(i just do not have experience like this...to send something off to "upgrade" ) @tylink720 that is like 150 USD turbo no? 😄 I dont think i have the "ease on my mind" with this kind of turbo. I just put over 7000k USD to "LINK" up my engine...dont want to blow it up with cheap turbo 😄     EDIT: https://www.cj-motor.com/gcg-turbo-charger-for-nissan-rb20det-rb25det-high?srsltid=AfmBOooVeOZ6CZ6r1AIv5m-KPaa6BvudIPJTY8LW78khkd-gQlsaCht9 I looked at this and it seems ok? It is that CGC hybrid and it costs around 1250 USD (with back shipping). Do any of you have experience with this hybrid on NEO turbo? I quickly look thru the forum/web and it seems very good.
