Piggaz Posted March 6, 2012 Share Posted March 6, 2012 Top bearing. Ignore the scratches on that photo. It's where we pused the piston and rod out. Bottom bearing. 15 months (10,000 kms approx) of running E85 using 300V 15W-50 oil. Engine was alive for 32,000 kms and used the same oil the whole time. 8000 RPM generally was the shift point but it did see 9000 a few times. They don't look half bad considering the oil pump died and the head is as useless as tits on a bull.

Piggaz Posted March 6, 2012 Share Posted March 6, 2012 and didnt burn a drop of oil its entire life I'd say that would have to do with the super tight clearances and the run in . Spoke to Mik about the run in and it was long hard pulls in 3rd and 4th up to 6500 within 10 kms of being screwed together. He did that every night for a few weeks on Old Pac.

Piggaz Posted March 6, 2012 Share Posted March 6, 2012 What happened to the head to make it useless ? Oil pump smashed. Ex cam welded itself to a few cam caps, belt jumped a few teeth and every ex valve got a little frisky with pistons (bent every valve and scored the chambers) . Intake cam is ratto.

bigmikespec Posted March 6, 2012 Share Posted March 6, 2012 So RB30 time yeah? I would look at the condition of the valve guides (if they are not all ruined from failure) to see how they went with E85 Link to comment https://www.sau.com.au/forums/topic/386659-e85eflex-and-oil-choice/page/9/#findComment-6264345 Share on other sites More sharing options...
SS8_Gohan Posted March 7, 2012 Author Share Posted March 7, 2012 maybe the 15w50 was the key then. I know Midori built my 26 on 10w40 300V and i would think that is a standard weight/viscocity for a street R, and if there are indeed issues of thinning etc, perhaps the 15w50 covers that off and it's ok to run the 300V. Be interesting to see what Motul themselves think after sending them this info.

Be interesting to see what Motul themselves think after sending them this info. I would still like to have a sample taken and sent away although after it went bang I wasn't really in the mood! I don't think the amount of metal (or should I say bits of oil pump gear) would give a good and accurate analysis. A susmmary saying "Too much oil pump shavings in oil. May need to check engine" wont tell us much Maybe chemically the Ester base oil's with alcohol fuels dont mix but changed enough it doesn't become an issue. The longest mine ever went without an oil change was 2000 kms. Track days and dyno tuning it always got new oil.

nisskid Posted March 8, 2012 Share Posted March 8, 2012 with a drift car you'd be very lucky to see more than a few hundred k's between oil changes, i know some that wouldn't see 100k's. would hate to see how many a drag car gets, if it even gets 1 lol Link to comment https://www.sau.com.au/forums/topic/386659-e85eflex-and-oil-choice/page/9/#findComment-6267313 Share on other sites More sharing options...
Piggaz Posted March 8, 2012 Share Posted March 8, 2012 ^^ Does that mean an ester based oil is fine to use with an alcohol based fuel?

nisskid Posted March 9, 2012 Share Posted March 9, 2012 ^^ Does that mean an ester based oil is fine to use with an alcohol based fuel? (getting back on topic) it's actually more time that's important than k's. if you take your car for a thrash, have a bunch of contamination sitting in the oil, it has time to react with the ester even if it's not being driven. obviously the more k's and the more blow by = more contamination, so it's a mixture of a few elements really. but yeh, from what penrite say, they believe that you will generally need to change oil for other reasons before the ester begins to break down, so with regular changes it is ok. i'm gonna aim to change every few months which will be about 4-6 track days, so should be fine.

mmmE85 Posted March 10, 2012 Share Posted March 10, 2012 Iam going to try next oil change Shell Rotella 10w 40. Supposed to have good neturalisers in it. Seems to be all the rage with E85 users in the states. Its not bad priced either.
