Have we had any info about the effect of ethanol fuel on our motors, tanks, carbs, fuel lines etc? It seems that our petrol will contain an increasingly large proportion of ethanol as time goes on and I wonder if it will rot our bikes, after all water does dissolve easily in ethanol.
I dont think it will a large effect on the vintage scotts but it will certainly affect some of the older paint finishes and the older style of petseal tank coatings.I have had problems recently with flo liner,my previous favourite coating.I am now using the american por 15 and have heard no horror stories even when used with methanol…
I must admit that my memory of exactly what was said is a bit dim. (Well, it was a while ago and I probably wasn’t paying full attention anyway!) But at a lecture by a senior “suit” from Ford UK, I do remember him saying that they had been forced to change their carburettors used in South America, maybe Brazil?
I cannot say for sure what the exact nature of the problem or the cure was but a problem they certainly had. Caused, it seems, because in that part of the world they use a significant proportion of vegetable based raw material, ethanol(?), to make their petrol.
As said, it was a while ago; Ford has not used carburettors for quite a while for heavens sake and a lot of things may have changed. Also Ford carburettors were made mainly from a zinc/aluminium alloy while all the Scott carburettors I’ve seen are brass.
Brass a good deal more noble than the zinc alloys so on balance I’d think a problem with ethanol unlikely but as far as I’m concerned it is a case of “not proven” rather than “guilty” or “innocent”. In other words the jury is still out as far as I’m concerned, at least until some solid evidence either way is presented.
