Hi has anyone noticed more fuel consumption using E10 over E5? or is it just me?. last week we went from mid Cornwall to our daughters on the Hampshire Surrey border a distance of 254 miles. I normally get 45mpg from 1800cc on a run. This time it barely made 40mpg. Home to Exeter is dual all the way, the A303 is mostly dual then onto the M3. There were no hold ups no roadworks no jams a clear run. Has anyone else noticed a difference?

Yes, I've noticed a similar phenomenon with my Subaru. Running the same journey to and from work, which is almost exclusively the M25 and M1, at times of the day that are (normally!) affected by congestion, I'm able to keep an eye on the M.P.G. meter on the dashboard, depending on what fuel is used. I'd say that running on premium unleaded (E5) raises the car's M.P.G. by more than enough to be statistically significant-maybe pf the order of 2-3 M.P.G. When I bought the car, almost 4 years ago, the dealer suggested the occasional tankful of "the good stuff" and I've kept that adage in mind when filling up. The price difference is less than one saves on M.P.G., particularly on long runs. Believe it or not, my Subaru returned 40+ M.P.G. on a long run (yes, a VERY long run!) a couple of years ago. It was to Luxembourg and back, for a mini-break and I was staggered at the car's economy!

Yes, there's been quite a lot of press coverage re this - increased consumption when using the new E10.
As Andrew says, the "Super" or other branded, E5 is more expensive, but can pay for itself on economy - and might even boost performance!
And whatever, do not use E10 in a DAF or old car.

I used to treat the 2000 BMW E46 to a tank full of VPower (others are available! You have to say that, dont you!!) occasionally for a long journey. Now I always use it. On a run recently to Graham in Peterborough from Surrey I was pleased to get 42 MPG, calculated. I used to be pleased to get high 30s. It is always better now, I dont fill up so often. I have also noticed it "goes" better, smoother running, quicker acceleration. Its probably down to the higher octane, I have never put E10 in, although it is supposed to be able to take it.

Hi I'm glad I'm not the only one that has noticed the different mpg and performance, so I got out my calculator and did a few figures. I checked my local garages for prices and decided to use Sainsburys, currently E10 @ £146.9 per litre and E5 @ £153.9 per litre. To convert to gallons multiply by 4.546, so £6.68 for E10 and £6.99 for E5. so divide by (in my case) 40 this gives 16.7 pence per mile and the second figure by 44 gives 15.8 pence per mile. So believe it or not E5 is actually cheaper per mile. I know we are supposed to be doing our bit for the environment and all governments are boasting about their green achievements but when China has 1082 coal fired power station and is Still building more and mining 12,00 tons of coal a say to feed them I don't feel so bad. Plus the fact that the more of us use E5 then it might persuade the petrol companies to continue to provide E5 for longer which would be good for all classic car users. Anyway rant over have a nice day.

Yes, absolutely.
The increased octane might even boost the car's performance!
We won't worry ourselves with the protesters, who obviously have too much time on their hands.
