United Premium 100

[bigjim92]

I've done a google search, and can only find discussion on this fuel on other car forums (not holden) and a little bit of talk on LS1.

Anyway, I've noticed some United Servo's are selling Premium 100 fuel, which has a 10% Ethanol blend in it.

There is a United servo near me that is selling it, so I'm thinking rather than filling up with BP Ultimate like I usually do I will give this stuff a go, and see if Steve (mace) can get anymore out of the tune.

My 'concerns' are as to how it'll go in the 3.6L SIDI, I assume it should be fine, and I'm wondering if others have or are running this fuel in their VE's?
If you are, have you noticed anything, positive and negative gains etc?

You can obviously give it a go but just remember on long road trips or if your somewhere, where there's no 100 octane you'll have to settle for 98 which may make the engine retard the timing

I was thinking about that happening, I've sent MACE an email to see what he says.

I've read reasonable gains can be made from the E85 tune...the LLT is dynoing at around the 280RWHP (208RWKW) in the States (only read one reference though). Would just be necessary to travel with hardware/tune to revert back to if necessary.

[bigjim92]

I'm going to give the E85 a go Jarp.

I was talking to Steve and I didn't realise the servo down the road from me sold it, so I'll give it a crack, see how it goes.

[Jarp]

Excellent man...am looking forward to hearing your results. From the reading http://camaro5.com/forums/showthread...71#post3344260 it sounds very promising although maybe still a couple of issues.

[bigjim92]

Yeah I'm going to be interested as to what results this brings, I'll wait for the OTR and then start playing with the fuels.

Thanks for those bigjim...very, very interesting

I only use BP Ultimate, I would never put Ethanol in my car regardless of it being designed to run on it or not.

im not 100% sure,but i believe that the earlier sidi's aren't suitable for e85

[aaronevolution]

Shell used to have a 100 octane fuel called V-Racing. I'm not sure how it compared to V-Power 98 though.

Yeah Vicarious that is right only the SIIs are sold e85 compliant so would void warranty as will the tune ect...

V-racing was 98oct + 5% ethanol, it seemed ok but I could not justify the extra 7c per/L on top of V-power

E85 can be used on all models from MY10 onward, with the exception of the 3.6 until the MY12 was released.

[bigjim92]

The reason why the ethanol fuels can be used on the Series 2 from factory is because Holden added a sensor to the fuel system, this sensor detects the ammount of ethanol in the system and the computer deals with it.

Jarp, you'll most likely try the E85 before me as I won't be trying it until I've got the OTR, so I will be very interested to see your results.

[Jarp]

Was the sensor the only change...no changes to fuel pumps, injectors etc? That second clip you put up testing the fuels against each other was interesting. Based on that clip I don't think we'll see quite the same results as the Camaro because I think the Americans can only get 92ron (is this correct?) so if you run 98 already in Oz the gains won't be as significant. I put 10% in today just as a prep

[adr8]

I think Holden changed more than just sensors in E85 compatable 6.0 if i remember correctly they also had to change valves to hardened type valves and made some changes to fuel delivery system ie fuel rails etc because the high ethanol content eats away at the plastic/rubber in the fuel system.
I read that in wheels or motor magazine (cant remember it was back in 2010) when they dynoed E85 6.0 to see if it made any more power because E85 is suppose to give more mid range power/torque, the results showed no increase in power or torque

[bigjim92]

All the reading I've done, the only mention of changes between series 1 and 2 is that addition of a sensor to read the ethanol content, I've read nothing about changes made to valves, pumps, lines etc...

In regards to the dyno results, as shown in the video's above, on a stock car you probably won't notice anything, but a tuned/modified car is a different story, as the video shows.

If you have a look at the fuel system (even in a VX/Y/Z) there's pretty much no rubber hosing in them anyways - the only hose I managed to find that was plastic was the one coming off the fuel tank into the charcoal filter. It'd be interesting to see if they have a different fuel pump though.

Cheers bigjim...just to add it also seems that FI and higher compression engines show increased benefit of e85 use.

Correct, well according to those video's anyway.

I have the Series 2 so if i could get E85 in WA i would love to try it, but alas not available in the West. Unless my car said specifically that is was E85 suitable i wouldnt be using it.

Ive seen it for sale in Thailand 6 months ago, premium unleaded(98 RON) was 33 baht/Ltr ($1.05) and E85 was 22 Baht/Ltr ($0.70)

[adr8]

i am only referring to V8 not the V6 I definitely know they made some changes I read the article some time ago so I cant remember exactly what was changed but it was more than just sensors

[dmacey]

File injectors need to accommodate increased fuel volume required to use E85, from memory I think it's about 30% more volume.
