I'm taking the VRS on a long trip to Wales this weekend and was wondering whether putting a bottle of Octane Booster in when I fill it up will help the fuel economy much?

I already put Tesco 99 RON in it so also wondering if it is safe to add another 1.6 octane on top of that or am I risking damage? :confused:

Probaly not if most of it will be motorway constant speeds. You'd probably get further by spening the £5 or £6 the Octane boosters costs on a few more litres of petrol.

Or, make sure your tyre pressures are right and take any junk out of your boot.

HTH.

Boots going to be full of junk - I'm going climbing

Checking the tyre pressures tonight and the fluid levels.

Think I'll save the 4 or 5 quid for a few litres more 99 ron then

i did try the octane booster the other week, no noticable difference, best put it towards some vpower
