Thanks I'll look into it.. I'll watch the ses. Plus I'll dilute it more tomorrow with the rest 7 gallons of 93 unleaded. But I'm going to call them first and ask them. I seen the turbo blue 115 octane on there website. Thay sell it in unleaded 115. I believe it's called 115 turbo blue octane advantage which is a unleaded. So I'll find out. Thanks for the tip.

Never heard of 115 octane UNLEADED race gas before...


The highest verified octane UNLEADED race fuels I've ever seen offered, are VP MOTORSPORT 109 and SUNOCO 260 GT PLUS UNLEADED (109)

It will be interesting to see if this 'Turbo Blue' company knows something about formulating race fuel, that the VP and SUNOCO engineers don't...

Checked today. I messed up. What was I thinking? It was 115 leaded... I mixed it 50/50 with 93 unleaded. 10 gallons total. I got 4 gallons left. I'm going to fill the rest with 93. So did i damage anything? Should I buy injector cleaner or anything?

I suspect that you'll be ok since you didn't use 100% and you've been quickly diluting. If you have trouble it'll probably show up soon. Get to 100% as quickly as possible and stay away from the lead thereafter.

So if I don't see a ses light in the next 2-3 days I'm good. I go through a tank of gas a week.

If you don't see a SES light by now, you probably dodged a bullet this time.

Just to give you a much needed wake up call...

Here is a breakdown of the parts that would have been ruined if you continued to use LEADED race fuel in your car:


Left+Right primary catalyst pipe /w/ secondary cats and resonators: $4500

PRE-CAT 02 (LAMBDA) sensors: $540 pair

POST-CAT 02 (LAMBDA) sensors: $540 pair

Total price for just these parts...

$5580


These are just some of the parts that would have required replacement.

I left a number of other parts out, and I didn't even factor in LABOR charges yet...

Hopefully you have learned a valuable lesson here, and you'll be more careful in the future. Treat this close call as a learning experience, and take your time before jumping into another situation like this one again.

I guess a better question is what do most m3 dyno at at sea level on a dynojet.

I saw your other thread and see that you got a precise answer.

You should consider doing your own dyno runs there in Utah. I think that you could use my blending ratio as a rough guide as to what might maximize your power.

Also, your own dyno runs could validate the formulas. The runs will show "unadjusted" and "adjusted" for altitude. The altitude loss makes you sick.
