Super unleaded in aircooled engines

Post by Stevep » Sat Jan 02, 2016 3:42 pm

Just a thought does anyone use super unleaded in their bus? If so any benefits or not.

I don't think there is any need, unless you are building a high performance high compression engine you really are not going to see any benefits. Just normal unleaded is the ticket for anything stock or mildly tuned.

A few use it on higher CR engines to reduce denotation

I 'think' my stock 1500sp prefers super unleaded…its higher octane and helps it run a 'little' cooler (in my head maybe)

I dont do it religiously….i.e…for ease I top up at local ASDA with 95 octane
but if i'm at a garage that has 97 octane for a reasonable price, I splash out the extra £2 (or whatever it is) per top up

The fuels expert at my work tells me that the next round of fuel standards will have super unleaded as ethanol free as regular unleaded will have more ethanol that is incompatible with older vehicles

As long as it will not do any damage I may try a tank full and see how my 1641 TP runs on it! Any views.

That's interesting. In terms of ethanol "old cars" is anything before 2000 isn't it?

I tend to use it in my 30hp engine in the 56 beetle just for the additional ethanol really, don't bother in bus though

I once used it by mistake. Only twigged when I saw the light on the pump telling me how much per litre I was paying :eek: Didn't make any difference to anything that I noticed. Except my wallet :lol:

Apparently it does less harm to fuel lines than the cheaper stuff. Or so my mate with an old Jag tells me...
