Brad,
What the hell have you been doing with Optimax and ribbed condoms. On second
thoughts don't tell me.
Fuel useage in my race car is half a litre a minute at the moment so Elf
Racing fuel at $5 a litre would make for expensive racing. I'll stick with
optimax.

I haven't got access to my old lab equipment, and my current employer won't
let me use the Scientific section for petrochemical research, however I have
found three things:
1)Optimax is bloody good cleaning solvent
2)Optimax will destroy rubber seals, hoses and ribbed condoms
3)Elf Racing fuel is about $5 a litre

Subject: Optimax eating rubber fuel lines
Because of the elimination of lead from fuels, the oil companys have to
use a substitute. Aromatics such as benzol, toluene, xylene are used as
a replacement. Aromatic fuel blends act as a solvent with rubber parts
and require the use of synthetic rubber for fuel hose. Therefore if you
wish to run Optimax or Unleaded it is necessary to use synthetic-rubber
fuel lines and replace any rubber seals in fuel pumps or carbies etc
likely to cause problems.
I have heard recently of people having problems running Optimax. Just
this weekend at a rally I was helping with servicing. One of the cars
was running Optimax with old lines developed a fuel blockage in a 45mm
Weber. Didn't think of it at the time but i'll have to mention it to the
owner as a possible cause.
I learnt a lot of this information from an Aerospace book written in
1963 talking about fuels used in World War II so it aint new!
Craig.
