View Full Version : Octane?

Just wondering what octane rating is best suited to my 99'. Only minor mods, I usually run 98% is this o.k. or should it only be 95%.

Unless you make some major changes (boost, higher compression, etc..),
93 Octane is just fine. Just make sure you get the car tuned after putting on any modifications that alter the air/fuel ratio, etc.

Can using 98% cause any problems?

It will empty your wallet faster but it wont cause any problems with the car.

Like said above, no, but if it's leaded 98 it will run your O2 sensors out quicker :thumbsup:

Leaded petrol was phased out a few years ago here so all our premiums are unleaded.
