Cheap Petrol False economy

Well I've noticed the same from Shell petrol as well, when compared with Sainsburys petrol that I usually used I would get about 50 miles more out of a full tank of petrol. Giving me probably 42mpg instead of around 38mpg. OK there could be other factors at play here as well I don't deny that...

As has been said it is the additivies that Shell, BP et al add to their petrol that seems to make a difference. Yes the British Standard for petrol does specify a minimum amount of detergent for petrol, but I suspect that the big petrol co.'s either use better detergent or better amount of the stuff.

Slightly off-topic but I once filled my tank up at a Sainsbury's garage with just under 46 litres of unleaded which is a bit strange as my car supposedly had a capacity of 45 litres, and no I hadn't run it empty, it wasn't even showing a warning light yet.

I fill up at Tesco which is the cheapest around locally.

I use my Clubcard and Cashback Credit Card together to get the best bang for my buck.

Think thats the best way to go........ Im happy anyway! Never noticed a massive difference in Economy - Il be going diesel when my MOT runs out (Next June) Peugeot 106 or a Saxo Diesel. Super Economy Ahoy!!!

I think that Tesco also offer a premium priced fuel, at some filling stations, now, too.

So EVEN THEY are telling us there's a difference!!

Some find a difference some don't. Also as it's getting colder you may get better fuel economy.

Octane rating. Not going to make much difference on most cars, certainly not worth the price difference.

There is a difference for cars which are mapped to run on it, just a waste in most other cars IMO. There was also research done into the 'premium' fuels in performance engines, and the Tescos one came out the worst.

I have always used Tesco diesel in my PD engined Golf.

Last month i used BP Ultimate diesel to see if the extra cost was worth more MPG, at 99.9 a litre,i was hoping so.

Unfortunately my fuel light came on at 480 miles instead of the normal 500 plus, so i was very disapointed at the result, so i went back to Tesco.

I have been told that the ECU may take a while to get used to the new fuel, or if i dissconnect the battery for half a hour, then reconnect, the ECU will then adjust to the new fuel.It could be a load of rubbish though ???
