Q: Do CITGO products contain ethanol or methanol?
A: CITGO does not use methanol in its gasoline. CITGO gasoline may contain ethanol, but primarily only in select areas where it's the oxygenate of choice to meet federal regulations for reformulated gasoline. Regulations require that if a gasoline contains ethanol, that fact must be posted clearly on the retail dispenser. If you don't see this or a similar posting, the gasoline shouldn't contain ethanol.

i got this from the citgo website...  don't know if it helps.

Walmart SuperTech Carb/Injector cleaner is all I can remember using in my vehicles for years.  I haven't noticed any problems with it eating up the rubber either.  I replaced the hoses when I had the tank off for repainting last year and the old ones looked OK (I think they were original and over 20 years old!).  Replaced all of them anyway though.

My 07 calls for 87, so that's what I run in it...

The way I understand it, we're talking apples and oranges here. Or to be more precise, miles and kilometers  

RON is a way of measuring octane and most(?) European and Japanese motor manufacturers use it in their technical specs. However, it's not the method used at most American pumps - if you look at the little yellow sticker on the side, you'll see that it's measured as "(R+M)/2".

In that formula, R = RON (which actually means Research Octane Number), and M=MON, which means Motor Octane Number. Both are measures of the performance of a fuel - MON typically refers to performance under a higher severity load than RON (like racing or aviation applications), so for a given fuel, MON is typically a lower number than RON. Anyway, the reason this is important is that the "pump octane" is an average of the two numbers. So, if you have a fuel with say a MON of 83 and a RON of 91....

(91+83)/ 2.... dang, I have to take my socks and shoes off for that one.

So what this means is that if Suzuki says "91 or higher RON".... the 87 gas at an American pump may already meet that spec.

Y'all have fun with the cheap gas, now! (Just broke $4/gallon here at the cheap places today.  Urg!)

You think I'm gonna hang around & ask the guy after I syphoned his gas?

"Hey, Buddy, what kinda gas ya put in this pickup?"

I am no expert but I always thought that higher octane fuel burns a bit cooler due to more efficient combustion. Remember some biker saying he used high octane stuff in the summer heat in his aircooled bike. Does this make any sense?

When I bought my 1987, the previous owner said that he always ran premium, so that's what I was running until I read that it was overkill. I switched to low octane and after a few weeks noticed that my header turned a God awful yellow/blue. It wasn't like that before I switched down. I'm back to using premium gas. It's only a few cents more to fill up with regular being $4.00 and premium being $4.20 in my area. This can easily be debated, but for now it's high octane for me.
