Tire inflation is important to fuel economy. Even 1 or 2 psi above the recommended pressure will yield positive results. Also, (in the US, at least) different brands of gas have different fuel additives in them... my V70 gets it's best mileage with Shell or BP.

I have run all of these tests and can confirm the additives in V-Power do have an effect on engine cleanliness, engine power and fuel economy. Long term use of V-Power (or equivalent) WILL ensure your engine runs at it’s best and will improve and maintain fuel economy and engine power.
