Do you get less mpg with petrol from Tesco?

[Quiet Man]

I have just driven 1000 miles only using petrol from Tesco and then switched to one of the brands and at once the miles per gallon increased by 3 mpg. Has anyone else found this?

[Skids]

You'll find that the cheaper petrols give you less miles per gallon, hence they are cheaper. Also, Low Sulphur unleaded gives you less miles than normal unleaded does. Cheap fuels and and low sulphur fuels have lower calorific values than the good stuff so your car is obtaining less energy from them. The best for your car is leaded, which you can't get anymore.

How the hell can you be so accurate? Different driving conditions make something you are talking about,impossible.

Thats odd because Im pretty sure all the regular unleaded petrol in your local area will come from the same refinery.

Yes, it might come to the garage in a pretty white/blue/red tanker, but they all fill up from the same distribution point. Tesco doesn't have its own extraction/refining capacity, or its own bulk distribution network either. It just buys on a contract basis.

This question should have been asked in the Myths Topics!

Listen to buildersmate.

Buildersmate is right!

Agree- you see tankers with all kinds of brand markings going into the Buncefield Depot

Yes i was also told that its exactly the same fuel in varying distributors, unless you are buying something like Optimax.
