^^ that's fine but for those of you that often daily theirs & do repeated short trips is why the oil quickly grenades itself.

I wouldn't run my oil more than one weekend if my temps were getting that high. I have a Setrab 619 oil cooler and my temps max out around 230, so I feel more comfortable using the oil for multiple events.

That seems a little high to me, your car could benefit from an oil cooler.

I've used E85 heavily around 40k miles on my 86, with a similar setup to someone else having a CNT UEL and OFT. I used it locally and it was very fun, the extra power boost is intoxicating

I also calculated it was close to .90 cents cheaper than 93 most of the time so the mpg hit was slightly countered by cost.

If I ever plan to do a long distance trip thats more than 210 miles round trip, I fill with 93 and swap the tunes, that's assuming an over 35 percent range hit on the vehicle and that's a little on the high side estimate for me to be safe.

Also rather than than the 7500 miles change intervals I cut mine down to 4500, only because the oil consistency and smell had changed and I wanted to be safe. I haven't done an oil analysis but it doesn't hurt anything but my wallet to play it safe and shorten the intervals. I suggest you look into doing the same

i went back to 98 or as close as i could bear.. i got it down to E13... god 98 is SLOW! back to E85 for me!

I've been on E85 since 2014 . . . it's cleaner for the environment

. . . our 98 is crap.

Actually I got to e85 recently. Cuz I started running out of things to mod....lol

I noticed my oil is a lot more watery when cold. *it drips faster, but seems the same when hot.

Will report everything I notice long term wise + maybe oil report.

When I did the math I found E85 cost 11 cents per mile and 92 was 12 cents so it basically evens out.

That's interesting, I had much better cost differences, 93-91 prices change so much more than e85 so I guess that helped. Also in my area there was only one racing fuel station with e85 so he would always competitively change prices.

Here is my blackstone with 4 autocrosses on flex fuel. 2750 miles on 0w20 synpower

With the supercharger, I tend to go thru tires much quicker and have more wrinkles on my face from smiling when I run e85.

Lantanafrs2 · 10-20-2018, 10:45 AM

The only long term problem for me is the desire for more power. Header made it better but will a snail make it wail?

Sorry to revive an old thread, just saw this and that Black Stone report looks great. Mind giving an update now? Also what kit/tune are you using?

I'm running 0w40, do you think that would change how it reacts with E85?

Oil weight should make no difference w/r/t E85. I was using the moto-east kit with the evap harness, tuned on ecutek.

Sadly, I moved up to the PNW where E85 is hard to come by, and I stopped using it. But E85 never caused me any problems.
