ever wondered why shell optimax and v-power have a sweet smell at the tailpipe ?
grain or bio mass alcohols ethanol/methanol/toluene have been used for years as octane booster, probably in all the cars they say it might destroy

Isn't this a similar scenario to when leaded fuel was phased out? Cars were modified to cope with the "new" unleaded fuel, I'm sure some modifications will become available to the masses to convert their cars to run on this E10

Shell V power/Nitro is listed at standard 5% Ethanol - I have run it in the Golf for the past 18 months, it was MOT'd last month & the tester was amazed at how low the emissons were. Not that relevant I admit to this topic I admit lol.
Wasnt it a high Ethanol content that caused all the issues with Morrisons petrol a few years back?

It was Shell V-Power which I'm convinced, burnt my HG out between the cylinders. I'd never used it with my Golf before so I stuck twenty quid in. Within two days, the HG went.
Maybe the HG was on it's way but I won't use any high octane stuff after that.

Lol.
Highly unlikely that higher octane fuel caused that, if anything it would prevent it by resisting detonation more than lower octane stuff.

*Yawn*. It's neither harmfull nor does it transform your car into a gas muncher. In theory ethanol has 32% less energy compared to gasoline. So in theory higher ethanol content causes higher fuel consumption for the same power delivery. In reality adding 10% instead of 5% ethanol to gasoline is a negligible difference - the air temperatur and most importantly behaviour of your brain resp. right foot has a much bigger influence to MPG. We have had E10 fuel for a long time now - I have never heard of any fault caused by E10 fuels... Even the fragile KE-jetronic eats it happy every day for hundreds of thousands of kilometers. A mate of me runs his W124 on E70 without any issues (apart from getting the stuff in the first place). En contraire; ethanol can absorb water - this can only be healthy for any fuel system if water contents are reduced. Sure - for long-time storage E10 is probably no the best to have in a fuel tank - but for every day use there's not a single problem with it. Additional, ethanol has a better octane rating - E10 fuels actually have up to 97-98 octane if sold as regular 95 octane fuel - but given the fluctuating amount of ethanol (many times you'r putting E5 fuel into your tank anyway as there's a shortage of ethanol) that's not something to rely on. Owners of carburated vehicles may have problems with E10 fuels. In theory. I've not run it, but I sure as hell will! All in all - it's new - but it's not bad. And of course the oil industry wants to sell expensive fuels - spreading a bit angst wont do them any harm, does it?  |

I've ran the Vitesse on pretty much nothing but Vpower since the new engine went in and had absolutely no adverse effects.

I ran the Imp on Tesco 99 for a while with no trouble, and that is an ethanol-boosted octane number. Think it's been e10 for ages - certainly was before the lambda destruction fiasco a couple of years ago.
Currently on v-power, and it loves it.
One thing to bear in mind is that nitrile doesn't like constant immersion in modern petrol - it shrinks. Caused huge leaks from my Strombergs, where the o-rings are immersed. Viton is much better at resisting it, but can deform a bit...

If you're going to use E10 make sure your hoses are ok to use with it (SAE J30 R9 (or R10)). And also set your car up for it as those of us running carbs and no electrics to adapt fuel settings on the fly will notice a difference. We do an event called the 10CR (10 countries Run) every couple of years. Anyone filling up with E10 was getting more fuel vaporisation and the PI engined cars were lucky to get to the top of the mountain passes. The cars sold in Switzerland back in the day had different metering units to cope with the fuel, temperatures and elevation. It's a bit of an extreme example as not everyone wants to go up Stelvio etc! But it's worth realising it doesn't like heat so if you've got it in your tank and your car is running a bit rough in traffic on a hot day, you know why. Anyone of us on the run avoided E10 like the plague as the cars ran like a bag of poop on it.

Don't know where everybody has been but ethanol upto 10% has already been in unleaded petrol for the last 2 or 3 years, it HAS caused documented issues in older motorcycle carbs and DOES affect fibreglass petrol tanks (I'm in the VMCC and it features a lot in their magazine) oddly enough the only fuels found without ethanol were the higher octane ones (will post up which ones when I find the info out) it also affects older type petrol tank sealing compounds causing them to break up or detach from the inside of the tank.

VPower is refined to 97 or 98 whatever it is, not standard 95 boosted with additives like all other super unleaded in the UK.

No. Not the other way round. Optimax or V-Power is refined to 97. The other super unleadeds are 95 with octane booster added. I'm not saying there are no additives in it. There are, just not to get the octane rating up.
You really think Tesco 99 is refined to a higher octane than VPower?
Shell even used dedicated tankers for VPower.

I would be interested to hear if anyone else has excessive tank rotting issues running exclusively the higher ethanol fuel. I pretty much only use supermarket fuel which has been 5% ethanol for several years and the van doesn't get used much outside of the summer months, meaning fuel sits undisturbed in the tank. The bottom of the tank looked pristine but when I dropped it one day to figure out where a strong petrol smell was coming from I found the top surface which faces the floor to be in a pretty bad way, but still savable as it turns out, and this was not due to mud/salt ingress. retrorides.proboards.com/thread/126938My pet theory is the excessive volatility of ethanol sinks the heat away from the top surface causing dew to pool up there on cold mornings. But it's a bit difficult to verify without dropping the tank out to take a look. |

E10 is very common in France and Germany, I fill up my '96 Golf station and '98 Primera regularly with this and have got zero problems. They are both running perfectly for years.
Must say I don't use it exclusively because I refuell in Belgium as well.
To paint the picture; I live in the narrowst part of Holland (sky high fuelprices), so Belgium (25 cents cheaper) and Germany (20 cents cheaper, but E10) are close by.

Had quite a few problems with it rotting rubber fuel lines in older cars, much the same as unleaded did when it first came out so the same routine of changing all the flexible pipes for newer spec ones, other than that not really had a problem appart fom a few carb rebuilds due to disolved rubber in the jets and such.
