Ethanol Petrol E10.
Posted: Sat Aug 21, 2021 6:52 pm
From September this year most garages will be selling E10 petrol in UK. That's , as I understand-- 10% ethanol . It used to be 5%. It does not improve your emmisions but as ethanol is made from plant crops, its manufacture is more eco friendly.
The new fuel E10, is not so good with older cars, mainly it seems that it can affect the rubber components in the fuel system.
Recently I checked with my 2 local garages, both had E10 signs on the pump. One said it still had E5 in the tanks and would not be keeping it after it runs out. The other did not know what was in their tanks. Some garages a bit further away say they will stock E5 or and equivalent, -- 98 octane unleaded.
After some research, I found a quote from the Federation of Historic Vehicle Clubs, suggesting older cars should use an additive like Castrol Valve master Plus. Hagerty, the classic car insurer, recommends Millers Ethanol Protection Fuel Additive or Lucas Oil Ethanol Fuel Conditioner. There is also a Star Tron product on the market.
I know that in my fuel system on the Haflinger with Zenith cab, there are quite a few rubber washers and o-rings. Maybe they have been updated in the recent overhaul kit I fitted. But I not sure to trust that.
I wonder what other owners thoughts are with regard to this problem.
