Ethanol blended 98 ron fuel availability is clearly on the rise.... We have just had a United Petroleum servo open up that sells "Boost 98" here in Mildura.

What results are tuners seeing with the use these fuels as opposed to the likes of Ultimate 98 and Optimax?

I have read only recently that the results are quite good.

So tuners, what's this stuff REALLY like?

im very interested to know aswell... is it as bad as the media made it out to be?

mind u this boost 98 is lookin very apealing at only $1.22 a litre compared to regular unleaded at $1.29.7pl!!

Try $1.13 /LT in sunny St Marrys

This Boost98 is good sh*t, ive been running it for the last 5 months- no problems.

Feels much stronger than the normal PULP crap.

I have heard plenty of people give boost 98 a good wrap but I tried 2 tank fulls a couple of months back and the ute pinged it's brains out on it. Not just a little bit either! It never pings on Synergy or Ultimate.

Geea had the problem with sludge in his fuel system from leaving the fuel in the tank for a couple of weeks too.

I have been using boost from st marys since it opened never had a problem ..the wog did tell me though that it is good fuel but if you are to leave the car for a couple of weeks not to leave the boost in the tank and to run non ethonol fuel through the system

There was a very interesting article in HPI a while back where Street tuner Tuned an R32 GT-R on the stuff. And it gained 22rwkw, with no other mods, same boost ect... However he did state in the article that cars already tuned close to the edge will run LEANER by just adding to the tank. I think I'm going to use this stuff when mine is re-tuned in a couple of weeks. See how it goes.

Got any more data Street Tuner??

Xrturb and Leonb, Were your cars tuned for it, or did you just swap over from using something else?

- The write up by Street Tuner is in HPI no. 60 - Interesting read.

Are you sure he said leaner? As ethanol or alcohol blended fuels have more oxygen content(since the extra OH strand) which means they carry their own oxygen into the combustion process meaning that AFR's will be richer.

I have tuned a VY ute on Ulitimate and then did a retune on Optimax Extreme 5% Ethanol blend and what do you know there was no significant torque increase at any point in the rev range. It did however send the O2 sensors a little off though.

Now this isn't to say that the fuel wont work on all cars and IMO I believe that the ethanol blended fuels will benefit forced induction cars as the density of the charge is far more important than in naturally aspired cars and we all know how good the cooling capacity of alcohol. I will be doing some dyno testing on the bosses car (LOK11) in the coming weeks on the benefits of ethanol blends and will post the results.

I've been running it in my T for a few months now, it's GREAT!

I've had the car tuned on Ultimate98 and it was just too many $$$ so went to the Boost98 when it came out. The difference is very noticeable. After 3 or 4 tank fulls it just got better. As I'm selling the car now I've had it sitting in the shed for 4 weeks just so as not to put too many kms on her, started it up a couple of times to make sure everything was ok. Today I started it up again for a drive down the GOR. NO problems at all, runs smooth as silk. Much better than the BP Ultimate.
