If your just driving for pleasure don't keep note of mpg, if on a journey to get somewhere is the extra 10/20mph really worth the extra cost and possible points for the time you save? That's the way I look at it![]()
i used to drive 10-20mph almos everywhere until i got 6 points!!!!! then i instantly drop down to the speed limits the most ill do is 80 mph on the motorway.
i a;ways used higher octane fuel, i studied a degree in automotive engineering for a short while and found out the benifts of higher octane fuel arent just on mpg and performance but mainly there are a few extra additives and it is much better on the internals of the engine, mainly fuel injectors, hence why you can buy octane booster items from halfords but these can cause damage to the internals.
