Thoughts on E10 vs 98 vs 91

Actually now that i think of it, in a recent issue of street commodores ( the one with gups 700ish ci clubby on cover) there is a ls1 VL with fuelab ethanol sensors. Does anyone know more about this setup? Stock pcm possible to do this?

No where near as knock tolerant , and a loss of power & torque right across the rev range even after tuning .

Steer clear. Eflex /E85 on the other hand :nyuk:

Good to hear you found the same results as me. I tried 98 v's United 100 and the E10 stuff would knock easier and make less power with my blown combo.

I spent the time to re-tune to the correct stoich ratio and adjust timing etc as best I could but it just didn't work as well as 98, so I won't be going there again. Am keen to give E85 a crack one day though but we will see.

I was thinking with E10 and 91 that 91 was better overall, while I was aware of the knock resistance supposed to better with E10, I was assuming as the power generated per litre of E10 is less than 91, that it wasn't worth the few cents that are saved, so in my SIDI SV6, and Fiesta I have been trying to stick with 91 where available, but sometimes use E10 if I can't find 91 at the time. Sounds like I should be using E10 for these cars at least. I'll stick with 95 or 98 for the VX Clubby.

Best way to tell what is better to run is if you have a route that you used a lot like going to work measure fuel consumption for 3 or 4 tanks on one fuel then the same for the other. Don't worry about recording the price as the difference between E10 and 91 is about the same so lust pick a day and record to evaluate once you have your measurements. FYI I record the litres put in and trip km's as the calculator on the dash is not 100% accurate. Do that and then you will know for sure.

So what about 98 vs united100??

Made the switch a couple days ago, honestly can't tell the difference, price is roughly the same. Would this suit boost better?

Reading all these posts, not everyone has the same experience. Seems to be hit and miss as far as your own setup goes.

My new drag motor will be running E85. Seems like a fantastic fuel for a lower maintenance, full power effort.

Second tank now, and it does seem to respond better to united 100. At idle the car doesn't jolt as much and it seems alot smoother, doesn't struggle as much upto 8psi boost either. My last few tanks have been Vortex 98 from Caltex. So unsure how it would go against BP ultimate.

Personally I rate vortex 98 better than ultimate. It's always ran good for me, whereas ultimate has been hit and miss for me in the past. Although it has been a while since I used ultimate. I can use shopper dockets for vortex, which is another incentive.

91<---95--E10-----E10(with tune to suit)->98

I'm currently evaluating my fuel choices. I think I'll be going to an Ethanol blend as I've taken 98 about as far as I can on the tune. It's a pity Shell got rid of E10 as I'd be running it in the SIDI if it was available.

Simon, Shell has E10 in Sydney (as do all the other servo`s whether independant or not) i was unaware E10 was being rolled back though i have heard rumours due to it being avoided by the majority of people who pick overpriced 95 instead.
ACA IIRC just recently did a test of E10 from different brands and areas arund Sydney, they all returned a reading of 94.5 RON

Simons taking about the vpower e10. Not the 91 Ron e10 which is common everywhere.

Oh Ok, Gotcha :burnout:

Actually, it's ALL E10 from Shell in Victoria. There is nothing with Ethanol in a Shell servo here, it's almost like they spat the dummy when they lost the V8 Super Car fueling (V-Power Racing ) and decided to get rid of anything with Ethanol. I'd love to be running it in the 3.0L SIDI motor as I reckon it's work well, but as it's a fleet car and comes with a Shell card, I'm stuck on 91, which is slightly better than Mountain Dew ( but not as good as Crab Juice ).

I'm set to recalibrate the TechEdge WB controller and the LA1 gauge to read correctly for E85, so I'll give that a go in the 6Lt. At a really quick calculation for AFR and peak IDC, I may not have the head room I need. For E85, max power is gained from between 6.975:1 and 8.469:1 AFR ( theoretical ), so splitting the two and aiming at 7.7 and with my current peak IDC around 60% for 12.6:1, I'm going to be pushing 97% IDC on E85......

Simon.

Interesting about the rollback, a week ago I was travelling back from Brisbane to Sydney and stopped in a BP servo to fill up just north of Kempsey and noticed they have converted the pumps from E10 back to 91, usually BP seem to have E10. In Sydney E10 is much more common than 91.
