Fifth gear tonight tested a bunch of petrol additives in a laboratory at Oxford Brookes University on a Rover K series engine.
The magic products were :-
- Nitrox Hot Shot
- Wynns Octane Booster
- STP Power Booster, and
- NOS Octane Booster.
and the shock horror result, all REDUCED power output by at least 2%.
But of course, you guys knew that all along.
