Cdm2018 Posted November 4, 2021 Report Share Posted November 4, 2021 There’s been threads here and guess on many car forums about introduction of E10 well now several weeks after introduction to forecourts what have people noticed ? I have persevered with using E10 so it’s truly gone into the car now but I still noticed a waving hesitant character to car running. I had a service a couple of weeks ago and still have the hunting sound if the engine at idle and at high speed it’s not the same as before ? my lotus garage guys told me to stick to it and not swap on occasions to Super-unleaded. read some news items where other people notice drop in fuel economy as well as sloppy drive to their cars ! any others experience anything ?

jerzybondov Posted November 4, 2021 Report Share Posted November 4, 2021 Don't Evoras want you to run on premium (so non 95 and hence not E10) or have I got the wrong idea from somewhere? Quote Link to comment Share on other sites More sharing options...
Gold FFM TdM Posted November 4, 2021 Gold FFM Report Share Posted November 4, 2021 It says premium inside the fuel flap and in the manual , but I think they mean 'not rubbish American stuff' and if possible a decent petrol station not farmer Fred's fillin' station in a field where the fuel is sold in blocks. incidentally, whilst I don't run on 95 RON most of the time I have filled with E10 when there was no other option and it seemed to make no difference whatsoever, but it was only one tank and mixed with the old expensive stuff.

I have only used super in my current 430 and previous S. thought this was as they were supercharged and the car prefers the good stuff. I now only get super E5 for all my garden stuff and the other cars (except the wife's RR) Quote Link to comment Share on other sites More sharing options...
Mark Blanchard Posted November 4, 2021 Report Share Posted November 4, 2021 I'm using Ethanol free Esso 99 Premium, but it's not cheap. 161p a litre here in Henley. Swines. Quote Mark www.lotusespritturbo.com Link to comment Share on other sites More sharing options...
Cdm2018 Posted November 4, 2021 Author Report Share Posted November 4, 2021 According lotus website posted somewhere here Evora was deemed suitable for E10 however I noticed differences as stated and was wondering if anyone else has now experienced any issues without resorting to the super versions that above replies suggest ? 1 Quote Link to comment Share on other sites More sharing options...
Gold FFM C8RKH Posted November 4, 2021 Gold FFM Report Share Posted November 4, 2021 Only ever used super unleaded on my NA, and I believe from 400 onwards it was stipulated to use super only. 1 Quote Alcohol.

Simon Bateman Posted November 4, 2021 Report Share Posted November 4, 2021 Same here. It's tuned to run on super unleaded and based on the typical mileage of a Lotus owner, is not much of a cost uplift in the overall scheme of things. My understanding is that all UK sold cars 'can' run on 95 octane, but I suspect it won't run as sweet or to it's optimum performance. Lotus also state they will run on E10 but why bother. I did the sums a while back and for 5000 miles per year, super unleaded was the same cost as a curry for me and wifey 😀 1 Quote Link to comment Share on other sites More sharing options...
Cdm2018 Posted November 4, 2021 Author Report Share Posted November 4, 2021 I wonder if the maths for using super to E10 is still a factor ? I am thinking given I driven about 5-7k a year if the cost difference never mind cars efficiency is mega probably around £100 extra obviously dependent on which garage you use or if you live in London which I don’t ! 1 Quote Link to comment Share on other sites More sharing options...
jerzybondov Posted November 4, 2021 Report Share Posted November 4, 2021 I suspect the running issues you've noticed are more likely due to the ECU retarding timing due to the lower octane rather than anything specific about the ethanol content.

Cdm2018 Posted November 4, 2021 Author Report Share Posted November 4, 2021 (edited) sorry to sound like dummy Not sure what this means but I gather I don’t have worry & carry on using E10 ? Edited November 5, 2021 by Bravo73 Quote Link to comment Share on other sites More sharing options...
jerzybondov Posted November 4, 2021 Report Share Posted November 4, 2021 Well the ethanol isn't your problem - it's using normal unleaded that's creating the hesitation So if you're OK with it crack on, it won't hurt the engine (as long as you don't notice any pinking- a tinkling sound at low revs in high gears). Or just do what the rest of us do and pay the govt some more tax because the manual/handbook tells us to. 🤣 1 Quote Link to comment Share on other sites More sharing options...
Cdm2018 Posted November 4, 2021 Author Report Share Posted November 4, 2021 I assume as I get car serviced at lotus every year they pick up on any concerns about engine issues ? As I got car service not long after using E10 I assume all was ok with engine ? Quote Link to comment Share on other sites More sharing options...
pete Posted November 5, 2021 Report Share Posted November 5, 2021 Not sure what problems they would notice on a basic service Quote hindsight: the science that is never wrong Link to comment Share on other sites More sharing options...
exeterjeep Posted November 11, 2021 Report Share Posted November 11, 2021 Had a few problems with one of our quads, it is not used much, has been cutting out, the odd back fire when it is turned off. When It cuts out is difficult to restart. Phoned the Suzuki quad dealer, he said it could be water in the fuel (we keep ours in a garage anyway) or stale fuel. Don't use E10 in these bikes, he said that E5 has the same issues in such machines that are not used much. Suggested draining the fuel and re-filling with fresh. Will be doing that today. Also spotted a warning notice about E10 in Stihl products at a Stihl dealer, don't keep E10 in their product for over 30 days. Quote Link to comment Share on other sites More sharing options...
