Theres another united store for E85 on old Geelong road, Hoppers Crossing.


What happens if you put E85 un-modified car?
Cheers

Boom!

i gave subaru australia a call today to ask if a stock standard GTB can be run on E85 fuel and the official response was that

"as long as the octane count is 95 or above it should be ok".

that was qulickly followed by

"however, we take no responsibility for the choice of fuel you use."

i'm gonna fill up with E85 next fill and see what happens, unless anyone else can provide some reasons, opinions or preferrably facts as to why it wouldn't be a good idea.
will let you know what happens.

hopefully not "Boom"

i'm serious about the response subaru gave me, and judging by your response i shouldn't be serious about filling my car with it.........?

[deadlegs]

i even asked about the ethanol drying out rubber hoses and stuff and they said that shouldn't be an issue. i don't know enough about E85.

unless your going to get a tune for E85... dont run it in your car

that sounds pretty definate so i guess i'll steer clear. must be pretty poor advice form subaru then.

Justin do you mind clarifying something:

The plastic Jerry cans you were storing e85 in - were they the normal type hardened plastic that you would purchase from autobarn/ supercheap/ repco?

I bought a 20 litre Jerry can today but it says on there "not suitable for racing fuel"

Wondering how long you had the e85 in there for when you tested it?

Im only using this for track days etc, and for tomorrow when I have dual duel tuning (filling up another 20litres just in case)

Sorry for the late response...

The 2x slimline jerry's I bought off gambit and they are cool for E85.....with the wide body ones it doesn't state if you can use them for e85 but no mention of "not suitable for racing fuel"...

I haven't had any issues / problems with my jerry's....I kept E85 in both jerry's for a maximum period of 3 months so far?

Glad your liking E85 and enjoying the new power ride

[dr20t]

Thanks Justin - much appreciated mate

Yeah I bought two slim ones and have borrowed a vp racing fuel 20 litre drum from a very generous mate so hopefully 60 litres will be enough for the upcoming track day on sept 14th

Gonna have to fill up on the way down there (about 125km from here)

Need to factor a full tank for the drive there and back and at least one full tank for the track day given the flat out driving to be expected.

Hopefully three jerry's will be enough

Hi guys.

Just wondering about mixing E85 with 98 ron fuel. I have been talking to Michael from MSR cause I wanted to get dual tunes and he said that I would have to run the car on E85 all the time and not to mix the fuels. If i had, say, 5 to 10 litres of E85 left and wanted to fill up with 98, what would be the issue with mixing to change fuel when I'm running out of petrol Apart from the obvious issue of not being near a servo that sells E85.....?

Thanks in advance

It will probably be fine but run a little lean, take it easy for the first tank. If you still have the o2 sensor feedback the ecu will tune the low end its self anyway. Your tuner should just run the fuel map a little fat for you.

I will nearly guarantee you will never put petrol in again once you try e85.

The stock ecu should handle about 30-40% e85 before throwing a fault, probably an o2 code, but I have no Subaru specific cases, just going by how other modern ecu's react.

Ideally you should be completely draining the tank especially when going from 98 to e85.

E85 is a faster flowing, more dense fuel. Therefore if your engine is tuned for e85 and you have say 10 litres of 98 fuel left when you fill up e85, you will run lean.

Conversely, if you had a little e85 fuel left and filled a full tank of 98, you will run rich

This is of course assuming you have two maps

You should never run a map not suited to that fuel.

Ideally you should also drive very sedately whilst running on even a slightly mixed tank of fuel

The proper way to do it is completely drain your tank, by disconnecting the return fuel line and draining it

And then - (this is something alot of ppl don't think about) - the gen 4 petrol tank has a resevoir which needs to be drained manually - this is on the passenger side of the tank - this is a gravity fed reserve / anti surge type arrangement which ensures the tank is never dry. This needs to be drained completely to ensure youre running new fuel
