Over the course of the coming weeks, I’m going to be running a little experiment to see if using performance or supreme fuel actually seems to have any difference. The science is there to a degree – a higher octane rating should mean better burn of the fuel in the combustion chamber. Will this hold water though?
I recently completed a long run of two trips, a total of 600 miles altogether. The journeys were broken up into two 300 mile segments, taken around 4 days apart. The first journey was completed on ‘standard’ that is 95 RON octane fuel. The second was completed with Tesco premium unleaded advertised as 97 RON octane fuel.
I’m not suggesting that the tests were completed in any sort of scientific way, but the first journey was completed with an average of 37.8 miles per gallon or thereabouts. The second was around 40.1 miles per gallon. Does this suggest that the more expensive fuel is the way forward? Well it is promising but I didn’t really measure it properly. I think what I’ll do for the next few weeks is continue with the premium and see where we go. Will the extra pounds at the pump pay off? Time will tell.
As always, we appreciate your comments so if you’ve had any experience using premium branded fuels please feel free to tell us about it.
