Hi guys,
My car is running an R-tech stage 1 custom map and runs best on Shell Vpower (99ron). Work pay for all my fuel (even social) but they have a account with a total garage that only has total excellium (97 ron).
Are there any additives that actually increase the RON rating of fuel so i can run excellium with an additive to achieve the 99 ron my car runs well on.
or is it a case of walking away from free fuel and using VPOWER?
cheers
