I'm in the planning stage of building a 307 SBC. Once normal unleaded is phased out, I believe that the choice will just be E10 or Premium. I'd prefer not to pay the Premium price if possible, so just wondering what specs. I should build the Chev to. It will be a cruiser, not looking at a high output engine.
Have also heard that ethanol effects some types of rubbers, like accelerator pumps in Holleys. Any truth in this rumour?

My 307 HK has a Holley 600 (man choke) Weiand manifold, MSD dissy & coil but otherwise stock. Recently due to advanced age and general confusion (that's what her indoors reckons) I accidently put E10 in it, terrific if you like a rough stumbling idle and hesitation off the mark, goes great and I get much better fuel economy with 98, worth the extra cash for a cruiser. My VX 6 runs like crap on E10 as well, whenever I am going on a trip I always use 98, get better fuel economy too. http://forums.justcommod...blend-fuels-article.htmlJust my 2 bob's worth...

My Cross8 was tuned for E10 or 95. It won't run properly on normal ULP as the octane level is too low. So E10 can't be all that bad. It's better than normal ULP anyway.

After working quite a while in the domestic fuel game & from what I've seen what E10 can do (destroy)lets just say it's nasty stuff.

I can show you a length of fuel line that's all soft & gooey from exposure to E10, and the diaphragm out of the Holden V8 fuel pump fromt he same car, that has a soft eroded surface on it, that wipes off like tar. It may be OK to use in EFI cars, but I won't go near it with an older car.
I also find it gives poor economy, even in newer cars, despite what others may claim.
I have the fuel records from 2 cars to back it up
Call it anal (well it is for tax reasons...), but I have a spreadsheet where I record all the fuel purchases, km, dates etc, and I have a formula to calculate the fuel consumption from the previous tank of fuel.
In the VE E10 consistently gets 490-520km from a tank, while the old ULP gets 600-650, and PULP (95) gets just over 700km to a tank on average.
I do the same trip each & every day, on the same roads, and at the same speeds, so it's a pretty consistent test bed.
In comparative terms:
E10 = 14L/100km
91ULP = 10.7L/100km
95ULP = 10.0L/100km
In my wife's VS, E10 barely gets here 300km from a tank (20L/100km), but the last 4 tanks have been 95 PULP, and each have exceeded 400km (15L/100km).
I avoid it like the plague now.
Cheers,
Mick

Basically if you have a carby or older injected engine without an O2 sensor, then you would be best to run Premium 95. A Carby or non-O2 sensored injection system cannot recalibrate the fuel required for the different fuel to air mixture ratio required to burn properly. You can rejet the carby, but then you have to run that fuel. If you have a modern O2 sensored injected motor, then you have the choice. At the end of the day. A lot of $20K plus valued classic and custom real steel vehicles with awesomeness that appreciates daily do not need to be run on cheap E fuel. Save a few lobsters or pineapples a year to ruin a special engine worth heaps. False economy to save $100's and ruin $1000's in the process. Lets start putting No-Name Brand recycled oil in our engine and retread tyres, along with getting into Nissan Tiida's to drive and we will all be special as. If you don't get it, then you won't get it. Steel is real. If it is old or rare - Cut it! http://www.ehlimo.com.au/ |

Thanks for the feedback guys. Looks like I'll be doing the old 307 (that's now turned out to be a 327 'cause somebody has bored it to 4") in the usual way and running it on 95.
I sometimes put E10 in my late model but it seems to be down a bit on power and I probably put the boot into it a bit more to get it to go, thus negating any savings at the bowser.
Makes you wonder how many people out there are puting E10 into their older cars, totally oblivious to what might be in store for them.

One fuel outlet North of Adelaide was a ethenol/bio fuel only outlet ,when this site was taken over and returned to ulp etc they had to replace all the pipes from the tanks right through to the pumps as it was all corroded and gummed up and the filters were still blocking up for some time after.
Nasty stuff.
