I was thinking the same thing recently !.. I have heard that the premium fuels burn hotter (than normal fuel) and was thinking that with an aircooled engine this might not be a good thing..
I am sure the guy with me experience will be able to steer us on the right track

Hi Massa.
126p engine was designed for leaded fuel. Important is the number of octane. Between 70.80 - these heads were designed for 90 octane number, and from 90 - to 95 octane.
Recent models have heads aligned on unleaded fuel.
In my opinion, more fuel octane does not significantly improve engine performance, and only help to accelerate engine wear (burn the valves).

ye thanks artur was starting to think that, normal unleaded it is then you always think that your doing good by putting good stuff in not always so eh thanks again

BIS can run on UL though can't it?
-
ye i just thought i was being kind to the engine by putting in a better grade of juice by what i can gather they were meant to run on normal unleaded thanks

Been running my aircooled for 3 years now on unleaded and I do loads of mileage.
Tried the fancy stuff for a while but noticed no diference.
(I test her performance on a hill) If she makes 40 by the top she's about right and the fancy stuff never got me to the top of the hill any quicker so I'm thinking it's a con :P

The 126 Bis runs on unleaded fuel (UL). Using premium unleaded rather than the regular UL does not affect the performance of the car.
