Been using Penrite 10tenths 15W-50 in my 340,000km RB30 pushing 350+ kw for the last 2 years on E85. Its used for daily/drifting and i don't have an oil cooler and at places like QR it cops 2 full day

Guy's. I have worked in the oil industry for many years, specialising in Automotive, Earthmoving, Transport, Mining and industrial. Also I have been lucky enough to be racing cars since the 1990's C

like mensioned a while ago, when i was with the ute team, we had 7 utes to maintain at one point. back then penrite was a major sponsor so we ran penrite everyhting. engine ware was very good. eng

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.

looks like the blow bye that accumulates in my catch lol. does your pcv vent to atmosphere.. i think with an unsealed breather system water absorption is much worse,

just wondering here, is the heavier oil eg castrol edge more likely to prevent a spun bearing than a lighter oil of say 40w?

would the 40w become to thin with the moisture absorption and power/heat and lead to more failures with ethanol

i forgot to post back again in this thread..

i'm on Castrol Edge 10w60 now - The oil has been updated and now meets the latest API SN / ILSAC GF-5, so you guys can go nuts with Edge. It's not that expensive either. For a track 26, i'd say it's the oil of choice as it's not that $$, and it's E85 friendly.

Motul 300V range has also been updated to be E85 friendly (officially now) but i think they want you to change it a lot more frequently if you're using it with E85

nisskid - the viscosity spread was a bit of a concern to me as well, but track 26's need a thicker oil, 50w at least and all of Racepace engines run Edge 10w60 and would probably see the most track time of any down here in Vic. They've been using it for years, so we definitely would have seen issues if there was a problem with it. I'll also be doing UOA testing on Edge in my car with E85, so we'll see how it holds up.

I think that with more regular oil changes if you're partaking in motorsport, you won't have to worry about the additive package as much. You'd probably find with oil testing you could get a lot more track days out of an oil change than you would normally think.

fair enough, yeh the w60 is understandable, i run the 20w60 ten tenths penrite "racing" which is designed for racing conditions, minimal additives and is 100% sheer free, penrite also have the "premium" range in the ten tenths, which is the brother range that is designed more for high performance street applications, it has similar viscosity's to edge, with high differences made with the introduction of additives like edge, good for street where the loads aren't too demanding, and cold start up is very important, however on the track, since there is no need for much start up protection, as it see's maybe a few cold starts a month, there is also no need for the additives which introduce complications at high load/temps.

i can't for the life of me find the 300V promo pic, i saw it on Athid's fb but can't find it! >:( can't find it on Motul OZ fb either, i'm sure it's there, might just have to look again...

it was like this..

Yeah i'm using Edge for the cold start as well as my car doesn't see the track much, so i think the Edge is a real good fit for a lot of us. E85 friendly, latest specs, not that expensive, 10w for cold start and thick enough for motorsport use.

i swear there was a 300V one... even had a brief chat to Trent about it the other day.... - maybe they got their promo pics mixed up and it wasn't meant to be for the 300V range? maybe that's why i can't find it...

the other thing to remember with additives, is that even if you're not getting high oil temp readings, doesn't mean you don't have hot spots, especially with turbo's as their bearings get stupid hot, and some additives used in some of the street oils around, do actually go off from the heat in these heat spots and create build up etc which can cause turbo failure etc. once again, for the street, probably not a problem, but for the track with turbo's getting to crazy temps, even if your oil temp gauge isn't reading real high, doesn't mean you're in the clear.

Ive been running this but in the 10w40 for around 2000km in my car and it still looks and smells like new my car isnt a daily either so it sits around all week :yes:

See this is something I'm not sure about, if your oil is still clean after 2000km then is it really doing it's job?

An oils job is just not to lubricate/remove heat from components etc, but also to remove carbon build up and clean the engine thus making it dark in appearance...

If it's still clear then I suspect it isn't cleaning very well, either that or you have a very clean burning efficient engine..

Thoughts???

      I know mentally you're set on the ATS clutch but honestly I'm a big fan of the Nismo Super Coppermix Twin. It's much cheaper and in some ways I think it's a better design for a street/circuit car.

      Just checked in first post and you should be able to bring it home November this year, right? I'm amazed you made it through four years of this. As hard as it feels now the rest will go by in a breeze in hindsight, I'm sure.

      Realized I haven't been back here in a while. Still here, still alive, still waiting for the car.  I went back again the only time last year from Oct-Nov for R's Meeting and drove it around some more, including a few laps on Fuji Speedway(in the wet, sadly). The car still feels good, but have a couple small things to address. I've been getting more parts but have slowed down still, and most of the bigger purchases are now out of the way. I find myself getting impatient more and more when it comes to getting started on this project; it's quite hard for me not being able to really dive in and start making this car my own because it's halfway across the world. At times it doesn't even really feel like I own one of these. Haven't really been motivated or had the desire to document the last trip on here or social media for, well, reasons... but here's some pics...it's also still alive and well as you can see: I've narrowed down to the last large part purchases(anything over $2k) before the engine build to be: 1) Ohlins Road & Tracks 2) ATS Twin Carbon clutch 3) Endless BBK with some custom options and 4) Kansai Service carbon driveshaft I don't think the budget exists for all of these this year, but I'll try for one or two items I think. Though, every time I look at my spreadsheet I sigh, shake my head, and get depressed just that little bit more.  'til later.

      It's a stunning location!  I've been to NZ twice but haven't made it to the North Island yet.  Definitely on the cards but the South Island is hard to tear yourself away from too... Looking forward to see what you can wring out of it once you can get it to hold together!  Be awesome to get a low 11 or even sneaking into the high 10's pass out of it.  That's a bloody quick car that most people will never experience in their life.  Enjoy!

      Nominally yes but I’m not really at that stage yet. Outsourcing to Japan is also a relatively good deal at the moment because their currency has devalued much more against the USD.  You would assume this but a lot has changed from the pandemic. Mechanics are in short supply and demand for fixing old cars has gone up from the cost of new cars. 250-300 USD/hr is not an unusual shop labor rate in California and you’re paying that regardless of whether the guy is competent or not. Coworkers have been quoted 3000 USD for a water pump and thermostat at a dealer on an N54. Oil changes went from ~75 USD to 150 on fairly normal cars like Civics. The cost of the oil and filter hasn’t even kept up with inflation.
