3.0L H6 on E85 = WINNING

[SIMBAT]

if you get an e85 tune, which fuel also which company would you recommend filling up with?

E85 is only available at United's but E-Flex is from Caltex

Being that the E85 is going to strip a lot of shit off the inside of your fuel lines, the common recommendation is to not change the filters until after 3 or so tanks of E85 have gone through.

I can understand this with the older model's filters being in the engine bay, but with the later model's filters being in the tank & before the fuel lines, is it still recommended?
Could we therefore expect some crap clogging up the injectors in the first few tanks as the lines are after the filter?
Would running Nulon's Total Fuel System cleaner(or similar) for a tank before the new pump install help/alleviate this??

Very interesting point you make here Jay , im pretty keen to hear peoples opinions on this also.

You about Matt, Mick & co ?

my experience: Going from fossil dead fuel to E85 and vice versa many time around ( including the 1st time ) I didn't see or experience any sort of clogging, filter getting blocked or being anymore dirty than usual...My last run from changing fuels and fuel pumps...inspecting the filter there's always going to be very small bits of sediment, debris etc etc...but nothing to alarmed about.....this just means that the filter is doing its job....the filter was clean as and wasnt off in color..

My very 1st sock going from p100 to e85....upon inspection....the only thing was the off color of the sock....but in regards to problem in function, blockage, and/or clogging....there was none.....

you must also factor station to station and how they keep there fuel clean, tanks, nozzle, ( basically maintenance and quality of fuel from place to place )

Cheers for ur feedback and sharing ur experiences so far Justin. Great that uv had no issues with function, clogging etc, puts my mind at ease a bit.

When Matt and I did the SC, DW65c install the factory sock was very discoloured at 82,000 kms. Installed the DW sock, double O-rings, no issues here to date.

Im only 1/2 way thru my 2nd tank, probably a bit early to comment, but im not expecting any issues. The SC'ed Lib is driving very strongly on the juice.

Matt has been testing the E85 from United Coffs in lieu of his Fozzy experimental vehicle - nothing but 85.

I spoke to United Coffs this arvo - 12,000 lts left in there tank and it gets filled every 2 1/2 to 3 weeks. They said the tank isn't allowed to get lower than
2,500 - 3,000 lts. Forgot to ask of the tanks capacity to roughly calculate local usage. This was an Indian employee (im not racsist) so not sure of accuracy.

Also im doing a return trip to Brissy on Saturday, so will be a good gauge for E85 highway economy, hopefully its better than around town and WOT .

Just read through this thread and pretty much didn't understand a thing but have a few questions none the less, which I hope might help some other people with less tuning knowledge as well.

1. I am assuming E85 is not the same as E10, I never run e10 in my Subaru's due to bad performance, poor economy and always been advised that its not good for the engine, so whats the difference with E85, does it have any adverse affects on the engine long term that normal 98 wouldn't have?
2. Is there a tune for 98 that would be more suitable for increasing, economy and performance for those that don't have access to E85?

been pretty happy with my economy though. Town is around 11.2, Hwy around 7.8 - 8.00 l/100km

Cheers
Ben

E85 and E 10 have very different octane ratings (e85 being 105).

I believe that means it's less prone to detonate and so you can increase timing and lean out the AF ratio.
So more power and decent fuel economy.
The fuel burns cleaner so if anything I think it will be better for your engine. There might be some components like fuel rails etc where they may not be suited for e85 and could have a shorter life but I haven't read anything to suggest that it would be a problem within the time you would own the car before upgrading to a new one.
I just did canberra to sydney and back on one tank of catex flex fuel (between 70-85% ethanol). Around a 550km trip. This was done with a preliminary e tune from Matt. Might improve when I get a re tune in person I think.
Very close hwy fuel consumption to what I would get in bp98 pre tune.

Although my consumption is pretty bad around town but that's just the way I drive.


If you don't have access to e85 then you could also get a 98ron fuel tune and still get some noticeable increases in power or economy or both. But this will also depend on how you drive, if like me you have more fun and accelerate more post tune then obviously your fuel consumption will not go down.

These are just my opinions from what I've experienced with my 2.5i.

Your H6 could have even better results.

any fuel with ethanol in it IS good for the engine as long as the car is tuned for it.......don't listen to the myths and stupid hypes ppl say about ethanol based fuels..... its been proven on this forum alone

e10 aka 95
p100 aka p98 with 10% ethanol
eflex
e85

I would choose e10 fuel over dead body fuel ....aka normal 91 and 95...

As alot of readers I havent had any first hand experience with ethanol fuels
The only fuels we have here in Katherine NT is 98 bp ultimate and liberty 98 with 10% ethanol
I have always been put off by ethanol fuels mainly due to low knowledge and experience
How different is 98 with ethanol over normal 98? Retune necessary I am assuming also?

pretty straight forward....what the difference is...98 ethanol is 98 with blended 10% ethanol.....its just as good as p100 or could just be....just another name for it...

I would get a re tune regardless what fuel your running.....if your coming from a stock tune...

The website seems to have the same info for both fuels....I have an XRT tune on 98 but am unsure whether using the ethanol blend will be beneficial without a retune or not as im still very inexperienced with these fuels

It is always best to tweak your ECU tuning to match whatever changes you're making to your car.

You definitely won't see as many benefits without correct tuning. Just small changes are required in this case, but should see worthwhile results.

When switching to a higher ethanol content:

You can run a little more ignition timing, for better torque and top end.

Your fuel economy will get slightly worse. If you're not utilising the anti-knock qualities of ethanol - you're just using more fuel for the same performance you've always gotten on 98.

By changing to eflex and only scaling the fuel up my car went from 103mph to 109mph. It wasn't done on the dyno so I cannot give you solid figures, but boost came on considerably earlier too.

Me too.

First cooler day 2day since switch over, with 9.8psi boost, iat's as low as 37*C and WOT , the low end torque is enormous, then hits 7150rpm fuel cut
so f'ing quickly. Matt's (Kido) tune is awesome, so is Tim's Raptor SC kit and E85, far out what more could a H6 owner want.
