I dunno... I pump up my tyres all the time after I fill her up with petrol

I'm a conservative driver - honest... never really rev above 3000 thesedays and cruise around 1500 - 2000

fill up half a tank everytime, last time i did about 190 km's on a tank which was few clicks till mid way

I've got exact half a tank of vortex now, usually drive by myself - light :P and also gave her new high flow lungs

i'll see how it goes
