i am having issues trying to locate C16 fuel for the YSi camaro. is there any issues with running sunoco 117? i have a local distributor pretty close to me and has it ready.

Just from personal daily driver experience, I'd say that SUNOCO has the best quality unleaded here in the Northeast/Mid-Atlantic. Doesn't matter what else I fill up on, I ALWAYS notice a drop in mpg by about 2~3 off of it. C16 is rated at what 116+ vs. Sunoco's 117 minimum? Both are leaded? I don't see why you'd have much problems with it, Sunoco makes good fuels, other wise I doubt NASCAR teams would have agreed to run that.

gas milage isnt an issue. lol. VP C16= 117 minimum octane rating

I know that gator, just making an observation as to Sunoco's street fuel quality. Just IMHO. Let me put it this way, my personal knowledge of Sunoco's fuel reputation is probably on par with VPs, and both are thought to be good quality fuels. Just my $.10 in this case.

You have to look at motor octane rating. I believe VP's motor octane and research octane are both at 117. I think you're reffering to Sunoco Maximal, which has a motor octane rating of 114 only. It would require a different tune than C 16. Definately less timing. I experienced knock with Maximal when I tried it with my C 16 tune. Be careful. I also took out a piston( doing 80-180mph blasts) on I-90 near O'Hare airport at 4 am on a Saturday and had to convince the state troopers that I hadn't been drinking or driving fast. So I might be biased against Sunoco Maximal also has a lower specific gravity which means you might have to add fuel also. I don't know how safe your tune is on C16, but it has to be pretty damn safe for it to be acceptable on Maximal. I would try to attain C 16 if I was in your place. I run that same tune in my Supra today and street drive it with C16 ( I am addicted to 40 psi for the street) and have not had an incident. Thanks VP!!

There ya go. Looks like Marko saves the day again. As far as the quality of both fuels, I don't think you'd run into any problems. That and I learned something new about octane ratings and what not.

marko, i dont understand. you said that you experienced knock on the Sunoco Maximal but you are still biased towards Sunoco? it sounds like the C16 was a better match for you.

Does anyone mix their own gas anymore?

How much is that race gas going per gallon now days?

Oh and yeah, what do you mean by add fuel, when you were referring to the fuel's specific gravity?

Add fuel to the tune because of the fuel's lower specific gravity. Both octane and the density of the fuel come into play so it's always best to tune on the same exact gas that you will be racing on.

I worded that wrong. I was typing that reply while on the phone...oops. Bottom line, in my case VP worked better and that's why I'm still using it.

Gator, are you looking for a specific octane? Are you looking for the most stable, repeatible, best quality octane or just a quality fuel to tune it in on and then run repeatibly? Perhaps that is a question that we should all ask since you're question as to "any issues with Sunoco 117" is kinda vega without context.

actually the more i think about it, the more it makes sense to stick with VP C16 since that is what teh car is tuned on and is running very well IMO. i will just look harder for a local source.

sb427f-car

Ahhh, there ya go. I guess my reason for asking that is, were you already tuned in on C16 or were you considering a tune on C16 or Sunoco, being which ever you could get your hands on more readily and cheaper.

already tuned on C16. just tried making some phone calls and got frustrated trying to get C16 locally. so i thought about 117 sunoco. but after thinking about it, its not real smart. plus i did some research on "MON" and its clear that i will be safer with the massive amounts of timing i run in this Futral tune.

You have a local source for C16, at Rev Xtreme.
