mgsontour Posted March 21, 2022 Report Share Posted March 21, 2022 Hi all Firstly I'm not questioning the price per litre ( although that's eye watering ) but I thought I had been leaking petrol but have parked it on wet clean concrete with engine running and no rainbows which I was educated some years ago is the way to see if me chariot is leaking. So has the unleaded at the pumps been watered down as well as jacked up in price? Cheers Quote Link to comment Share on other sites More sharing options...
udderlyoffroad Posted March 21, 2022 Report Share Posted March 21, 2022 Yes. 'E10' means (upto) 10% bio-ethanol content. Shouldn't really notice an appreciable mpg reduction in anything modern, unless it's high performance. Something running on a carb or older fuel injection might struggle and need the attention of a competent mechanic What age and type of vehicle are we talking about? Are you determining mpg from its on board read out, or doing numbers in your head? Also, I think whomever educated you missed the 'put cardboard down' step to really see if there are any leaks. Cardboard will soak up and stain even the smallest petrol leak. Remember that there is a fuel return pipe too, so your thorough visual inspection must include that.

B725 Posted March 21, 2022 Report Share Posted March 21, 2022 From the articles I've been reading people are getting less mpg from the E10 petrol so it can't be that good if you have to use more petrol to get to the same place apparently its not good for lawn mowers and such like. I have put an additive in my petrol for the mower and strimer. Quote Link to comment Share on other sites More sharing options...

Never had the cardboard part of the lesson but did get similar to 'wrap a length of blue roll around your CH radiator valves once a year to spot leaks' but back to me and me petrol: 2005 Honda CRV 2.0L and the dash board read out is about the same 25mpg as I chug around B roads and farm tracks etc I just seem to be going through an increased amount of fuel as I do the same miles and filling up more often. Is E10 fuel the cheapest unleaded at the pump? Maybe I should be using the premium unleaded for my age of bus? Cheers Quote Link to comment Share on other sites More sharing options...

Maybe I should be using the premium unleaded for my age of bus? E5 is usually reserved for 'premium' products, and I wouldn't have thought a CRV would benefit massively from it. I think you appear to be missing sufficient data points to draw any meaningful conclusions though. My suggestion, brim it, reset trip counter, run till bum squeaking-ly empty, brim it again, use latter fuel receipt to work out actual consumption. Use either a notebook or a spreadsheet to track it depending on your technology comfort level. Be sure to convert from litres to imperial gallons (4.54 l) not US gallons (3.something) for MPG. Apologies if your grandmother is now wiser re sucking eggs. Quote Link to comment Share on other sites More sharing options...
B725 Posted March 21, 2022 Report Share Posted March 21, 2022 When I was paid mileage at work I used the free app Fuel Buddy it was easy to use and each time you input litres and mileage it calculated the mpg for you and you could also add the cost and it then showed the cost per mile.

Morkin Posted March 22, 2022 Report Share Posted March 22, 2022 We have a Skoda 1.2 turbo petrol and it's reduced fuel consumption by at 7 miles per gallon ,and computer on short runs sometimes it's 10_15 different to before, you would not expect that fuel to do more they've got to get money back somewhere, Quote Link to comment Share on other sites More sharing options...
Vince Green Posted March 25, 2022 Report Share Posted March 25, 2022 I drive on the M4 regularly. There is a long section which is restricted to 50mph. It's amazing how much better the fuel consumption readout on the computer gets when you are doing a constant 50mph compared to 70mph Quote Link to comment Share on other sites More sharing options...
Gordon R Posted March 25, 2022 Report Share Posted March 25, 2022 Since switching to E10 I get 10% less MPG. Car is two years old. Quote Link to comment Share on other sites More sharing options...

Yes E10 is way worse for MPG in my Forester, the Govt figures are pure propoganda. So we now use way more fuel at ridiculous prices to do the same mileage, we have so much to thank this Govt for don't we!! They are worse than clueless.

paulinlincs Posted March 29, 2022 Report Share Posted March 29, 2022 Always used E5 in my car and continue to. Apart from the extra price nothing has changed. My wife runs hers on E10 and has noticed a difference in mpg by about 10-15% less. I also run my mower on E5. Mower goes like a rocket 😂🚀 Quote Link to comment Share on other sites More sharing options...

Strangely, since the new fuel came in my average mpg has actually gone up by about 0.4 mpg but I think that's down to the way I drive it ( I do a lot of motorway driving now) Driving style apparently makes a huge difference to fuel consumption Quote Link to comment Share on other sites More sharing options...
mgsontour Posted April 12, 2022 Author Report Share Posted April 12, 2022 For anyone who is interested, I've been using the higher priced unleaded at the pumps for the last few fill ups and wow what an increase in mpg Quote Link to comment Share on other sites More sharing options...

Stuck with E5 in my 3.9 landy at the moment due to no LPG so I am resisting the temptation to blip the throttle as nice as that sound is from two Cherry Bombs 12-15 mpg a good avaerage but it's fun to drive.

I was getting much better fuel consumption than that out of my 5.5 litre V8 Merc and i did floor it coming out of roundabouts.

How is it anything to do with this government? the E in E10 stands for European. Its a EU directive to cut emissions. So you can thank Brussels for that As for the price, its a world issue Edited April 13, 2022 by Vince Green Quote Link to comment Share on other sites More sharing options...

The percentage of BIO Ethanol that is in the fuel My wife complained about her car and having to fill it up more regular - told her to use E5 despite the cost - back to normal - except the price 😞 Quote Link to comment Share on other sites More sharing options...

I hate to think what the 5.3 Jaguar XJS that I used to run would do on E10. I barely got 10mpg, but it was certainly fun. Long gone, now, though.
