As title is the Golf GTI DSG compatable with E10 fuel?
-
Yes it is as per VW.
I've used a few tanks of E10.... can't see any difference.
E10 has been standard across many european countries for some time, its only the UK late to the party.
-
Same here Fred, also had a few fill ups with E10. Just wondered if anyone is bothering with E5 super unleaded. Just seems a waste to me.
-
Oh gawd, don't start asking people whether they think paying extra for their fuel gives them anything....

Always used V-Power and will continue, E5 99RON. Probably a placebo effect, but with the mileage I do the cost differential is two fifths of FA.
-
E10 is not recommended for GTI at least in Germany. The owners manual state to only use if E5 is not available.
-
My user guide says "Fill vehicles with a petrol engine only with unleaded petrol or petrol with a maximum ethanol content of 10 % (E10)"
-
Fuel filler flap on mine also says E5 ,E10
-
Could this be a factor in why uk testers seem to get more power and faster 0-60/62 than official figures? For my mk6 was advised to use super, so plan to when it finally arrives unless consensus here is otherwise.
-
Always use Super and most of those are E5 I’ve read Esso Supreme 99 is the only fuel widely available without any ethanol.
-
E10 is less fuel efficient than E5 so less mpg. I will continue with super unleaded even though it carries a price disadvantage. Found that my mk6 had less soot on the exhaust tips with 99 Octane.

Ethanol only has about 70% of the energy density of petrol, so E10 is about 3% less energy dense than petrol with no ethanol added, not a huge deal.
Pure ethanol has,a RON number of about 109. For those cars that are designed to run on ethanol, they run on a significantly higher compression ratio as they need a lot more fuel in per ignition cycle. If they had the growing space fir our food requirements and sugar beet/cane for fuelling, running cars on ethanol would be the eco way to go.

I’m getting better MPG on this new fuel I have to say getting high 45’s easily now :laugh:
-
Its only older vehicles affected, we've been using E10 in our MK7 for a while and had no problems at all
