Motorists find that additives don't work...
 

CHICAGO, IL (June 27, 2014) – Do fuel additives really work? In a GasBuddy survey, nearly 8,500 respondents doubted how well fuel additives worked in their experience, while 10,000 said they don't use such additives.

The results indicate a mixed bag, with 56%, or 4,717 responses, responding that fuel additives made no difference in their experience. 18% or 1,510 respondents said they experienced varied results, while 2% or 189 said they thought the additives made their car run worse than it was before they used the fuel additives.

That leaves just under a quarter of respondents users happy using fuel additives, or 24%- some 2,076 motorists- saying they felt that additives made their car run better.

"We believe the skepticism of our respondents is well-founded," says Patrick DeHaan, senior petroleum analyst for GasBuddy. "Some additives make exorbitant claims suggesting that fuel economy might improve by up to 25%. Unfortunately, none of these product claims have ever been substantiated by any government review or consumer agency."

GasBuddy has other suggestions for motorists looking to boost fuel economy or to spend less on gasoline. First, motorists can save over 10 cents per gallon by using GasBuddy's free smartphone app to pinpoint cheaper gas. In some areas, GasBuddy sends alerts before prices rise significantly, offering motorists a chance to fill up at lower prices. Second, driving defensively can result in less gasoline burned and ultimately lead to savings on fill ups. Third, motorists can learn about issues driving gas prices higher or lower by reading the GasBuddy Blog (blog.GasBuddy.com.).

It depends on the additive. I have to add an ethanol stabilizer to my GT-R to avoid clogged injectors that e-85 corn syrup can cause. The stuff works, otherwise I would have needed to switch back to one full tank of premium gasoline by now if it didn't.

Maybe I'm missing something here. Why would you use E-85?
Can't you get good gas anywhere?
Nice car and pi$$ poor gas.:confused:

E85 allows turbo and supercharger cars to run more boost and basically not blow up. We dont have High grade octanes like they do in Europe.

If you've ever been around a high hp car like a 800+hp GTR, viper, mustang, vette, lambo etc etc. They are usually tune to run e85.

I use Lucas gasoline additive in my gasoline vehicles from time to time. I actually see a little bit of fuel mileage increase and percieve a tad of performance increase. I also use PowerService in my diesel. I don't see any MPG or performance with it but need to keep the water/slime/gunk notorious in diesel fuel at bay. I stand behind these two products through personal experience, the other million or so?

Dave 105 octane is the norm. E85 must be monitored to assure it is at 85%. In cooler climates it can be as low as 72%. So those running e85 a monitor or tester is a requirement. The coupe is soon to be on e85. It's for performance not mileage. Although as cheap as it is it may hold in in mileage right now.

Isn't E85 dangerous for your fuel system if it's not set up for it? Are Crossfires able to safely use E85?

Re: Motorists find that additives don't work...
 

Where would you get 105 octane?
We can get 94 octane here in Canada at the regular pumps. Europe has 102 RON for high performance cars which is about 97 octane.
E85 is about 94 octane from what I see. Seems to have a lot of hype attached for performance.
