It depends on whether the rubber in question is resistant to Ethanol. It has nothing whatsoever to do with the vehicle being on good condition.
You have to be careful not to muddle up correlation and causation. Most rubber compositions are more resistant to ethanol than the ingredients in the complex, and varying, blends that make up petrol. The composition of petrol has changed enormously over the years, and indeed changes from summer to winter. Different brands have different compositions too. Then, add in the variations and changes to rubber chemistry over the years and you see that it's not a straightforward question to answer.
The chap at my local Shell, who services pumps for a living as well as having a small garage on the premises, says use his super unleaded, which will stay at E5, but then he would at that price Good salesman, eh?
I tend to use E5 because of the lower ethanol content, yes it costs more but it's not like I do a massive mileage in the camper. Mind you I live in the middle of England rather than a remote bit of Scotland so everywhere is nearer
I realised last Saturday that Tesco was now stocking e10 so I went for the 99ron e5 stuff. £25 quid later I'm barely out of the red. This bus better start pooping golden eggs soon.
You won't get golden eggs, if mine's anything to go by, you might get a small wet patch on the drive, however
No worries here, didn’t notice any issues on the 300ish mile round trip to Hayling Island - Beach Dubbin - home.
