octane booster?

You guys making a big deal about this...your ECU will make up for the poor quality of fuel.

Also i'm not sure that 91 octane E10 is any worse than 93. If they're selling 91 that has 10% ethanol added you've effectively got 93.5 octane because ethanol acts as an octane boost. If they use the ethanol to bump up the octane to 91 then that's crappy.

Either way i don't think any of you guys have cars tuned to the max that will blow up with 2 less octane points. The gas stations selling mis-labeled gas though are pretty crummy, false advertising is lame. But I'd think more of you would have done your research on this when it changed like last year:idk:

 
I used to make runs to NH to fill up my tank, now I cant even do that anymore. Kind of wish I had a 6 gallon can of 93 still sitting around, who knows how much someone would pay for stale gas lol

He is making a big deal about it because it is a big deal. 2 oct is huge when you have a protune that is pushing it for you octane level.

I have knocked before and it is something you don't want to do twice. I lost like 30 whp from being tuned on 93 then getting tuned on 91 that is huge. Plus, the ethanol they put in is not helping. I was tuned on full 93 then had a tune for Maines 91 with the E10. That is when I lost all my power. I had to carry a 10 gallon jug with me to get the gas down to CT to be tuned.

I have to agree to a certain extent. My car is tuned to 93 octane and it is a glaring difference when I do not get it or have pewpy 93.

I think additives are a gaff to a certain extent; there is only so far U can improve an already bad base with additves.... It's like adding koolaid to third world water and expecting the end results to be different..

If U have 100 barrels of gas persay and add ten percent whatever this years additive is... all of a sudden U have 110 barrels of fuels and I bet U the additive doesn't make U loose $$$ on said barrels of fuel but rather widen the profit margin for the bottom line.

ps: Just using barrels of fuel as an example, I know it is how crude is measured but I am unsure of it's refined cousin and the number is erronueous, just easier to use a round number for the sake of math & watch out for the MLB satelites... bart simpson had it right all along.

Ethanol's octane rating is 116 and you guys are complaining about them adding it to our gas

Although if it's 91 WITH the ethanol in it..that's super lame.

If you have that level of tune in which your car is that sensitive to fuel changes you should also have appropriate means of monitoring it's health. I've had knock events occur in cars, i've had it happen many more times than once, and it's not something you want to make a habit out of, but it didnt feel like the end of the world to me.

And I can say the same thing your protune reacted that way, my tune was fine with both 91 e10 and 93.

If you were to take 91 and then mix the E10 yes you would yield a higher octane rating. But what the gas market is doing is taking 87 or 89 oct then mixing the E10 and that is there new 91.

It all depends on how your car is tuned. If you run a protune that is conserative then you shouldnt have to much of a problem. But, if you take a protune that was pushing it a bit more you are going to notice.

Not to mention ehtanol can make more power but it takes more of it to do that.

You gave a good expample of what they are doing. I like the koolaid thing by the way.

LOL, you cant take sh?t and dress it up nice. It will always be sh?t.

when you are boosting at 23 psi it is a big deal.

 
tyvm... I used to own property in Cabo San Lucas Mexico and have lived the entire water thing more than once.

Although old and written by a into Vette's I thought this was at the very least educational; at least from my standpoint: http://www.idavette.net/hib/fuel/index.htm

My car is set to 27 psi so I feel the pain...hahaha.... Up until several months ago U could have talked to Deadbolt and they could have told U about my pain...

Your average over the counter octane booster is a certified rip-off.

Usually you get 1/10 of a point from those cheesey $4.00 bottles.

The answer?

"Cut" your crap gas with race fuel.

Also, living in Maine, do yourself a favor & have your car tuned for 91oc-that way there's no "I lost power" issues when running crapGas.

DSG tuned mine for 91oc, and I run 93oc most of the time, anyhow, as I found some in Casco at the Shamrock on rt. 302 (at the top of the hill)...

VP Race Fuel is available at NEAD in e-z-to-use barrels, it runs about $8.00 a gallon, if I recall correctly.

YUP! this is why I went back to EFI logics and got tuned on the 91 oct. Like I said it was a long trip so had to carry 10 gallons of gas down with me. Till I got the tune done I was buying VP Red which is the highest non leaded oct racing fuel you can buy. I was mixing about 2 1/2 gallons to a full tank of 91. I was paying about $55 for 5 gallons.

 
Meth injection is the answer to all this. It sucks though because meth+93 makes more power then meth+91.

Greg,are you SURE the shamrock isn't just mislabled.If they have 93 octane THEY are the only ones[and ill there to fill up tomorrow].For my peice of mind can you ask the owner for us if this is for real??My friend who has a gas station says there is no 93 being delivered in the state o maine.

Your friend is right. There is no 93. Hasn't been for some time. The funny part is a lot of you guys that think your cars can only run on it have been using 91 for some time without noticing!

Are you SUUURE? Ethanol is added after the refining process much like MTBE was. When they measure it and when the add the 10% to all grades makes all the difference. I'm pretty sure the lowest grade they make here is 87, if you cut that with 10% ethanol you get mid 89. So the 87 folks are getting quite the deal if they do it your way.

I dont know how they're doing it, nor will i pretend that I do. Seems like something that a few connections could find out though

You have to look at it like this. If it was 91 and they added the E10 it wouldn't be 91 anymore it would be like 93. So now it would be called 93 oct with E10.

Ask your source and see what he says. I am not saying I am right I am just choosing the common sense route and assume (which will sometimes make you look like a jackass and it has to me:))

I have tried to google this and found out but I really cann't find anything useful. I just know with 91 e10 my car made less power than with 93 oct.
