LUV DE COUPE

Hi everyone, just wondering which unleaded fuel people are using in their pre unleaded engines. In my XA 302 I use premium with moreys valve lube.
Thanks Brian

BP Ulti whatever!! Any of the 98 RON PULPs.

What I fail to understand, seeing as you cannot buy petrol with lead in it, why make any refrence to lead at all? Is this some stupid politcaly correct marketing speak? Why not call unleaded "Regular" and PULP "Super".

How long has the 100 octane fuel been available for?

optimax extreme has been out since either nov or dec 05.

In a lead fuel engine you shouldn't run any less than 96ron which is what leaded fuel was rated at. You can get away with premium (95ron).

I run BP ultimate and Mobil Synergy both 98ron. Don't have access to 100ron to try yet.

I run BP Ultimate mostly but will try the new 100 octane shell when I find somwhere that has it.

I have had problems with Shell Optimax going off before, re: if vehicle (bike in this case) has been sitting for awhile (week or 2) was very hard to start from cold - don't have the same problem with the other 98 oct - was told this had something to do with the additives they use in it.

I use only 98 Ultimate. 100 Ultimate contains ethanol

probably a stupid question but what is the negative effects of ethanol. I was only looking at the octane rating for optimax extreme...does the ethanol damage your engine?

I wouldn't use it in an old car. It can rot rubber seals, accelerate corrosion in the fuel system, lean off the engine, and produce greater evaporative emissions.
