Corrosive Joeseph: once I was told that unsaturated hydrocarbons are a problem source in fuels because at high temperatures they start to polimerize and it eventually leads to sticky mess build up in the motor.
So I assume there is not too much alkenes are left for you to get rid of.
On the other hand I saw a detailed composition list of a local E95 unleaded "gasoline". That list was impressive, contained 20+ components, most in the 2-3% range! These components probably form all sorts of azeotropes with each other.


@ Pumukli - Thank you...... That is what I was hoping for.

Unfortunately, I read much conflicting information......


This is what I am dealing with........ Appartently -

'Our Premium Unleaded 95 petrol exceeds the latest requirements of the relevant European Standard Specifications IS EN 228 and contains a detergent additive to help keep fuel injectors, inlet valves and carburettors clean, maintaining driveability and performance.'

European Standard Specifications IS EN 228 -

And just for comparison -


Gasoline in the US
'Gasoline in the U.S. is usually blended from straight run gasoline, reformate, alkylate, and some butane. The approximate composition is 15% C4–C8 straight-chain alkanes, 25 to 40% C4–C10 branched alkanes, 10% cycloalkanes, less than 25% aromatics (benzene less than 1.0%), and 10% straight-chain and cyclic alkenes.'

This is also an interesting read......
