does anyone know what fuel is used by supermarkets ie tescos/ sainsburys the reason i ask is a guy at my wifes workplace reckons he gets more milage from using shell/bp etc rather than using the supermarket stuff and says its common knowledge :?
 
It comes out of the same tank at Milford Haven :roll:

Its a placebo - does this guy drive exactly the same route, at the same speed, with the same load, changing gears just the same and in the same weather conditions to be able to compare?

Isn't 93 ron a set standard?
 
Hey, don't knock it - there is a credit crunch on y'know

Obviously spending 5p more per litre to get an extra 5 miles per tank helps keep some BP executive in a job, and saves the environment too. Its win-win
 
and says its common knowledge :?

ask him to prove it, but dont hold your breath.

its also "common knowledge" that Ken Livingstone (when he was Mayor) said you can't ask for black coffee, and you must say with or without milk, because to say black is racist.

It was made up by some newspaper, that is not what he said
 
My dad worked at an ELF distribution depot for years and various companies used to haul from there.
He said that all the tankers filled up from the same storage tanks then additives were then put into the tanker to suit the customers requirements
So basically when you fill up at the pump the fuel is different even though it comes from the same depot
 
So with the high octane fuels its just additives that are mixed with the petrol after it comes out the same tap?

That may be so, Woody, but according to Honest John additives are supplied subsequently:
Shell Optimax 98Ron was the best petrol, giving better performance and economy for most (though not all) cars. This has now been replaced by Shell V-Power 99Ron part bioethanol which is even better. Shell and Texaco petrol traditionally had the best detergent packages, but BP Ultimate petrol now has a good one too, and Esso has also introduced a high detergent petrol. Lack of detergent and a high proportion of short runs from cold is what causes most petrol engine fuel system problems, so if you buy your petrol from a supermarket seek written assurance that it at least meets and preferably far exceeds the British Standard for detergent in petrol.
Can't envisage too many punters demanding documentary proof that their 12 gals of Asda'a finest contains the latest additives, can you? :wink:
 
So with the high octane fuels its just additives that are mixed with the petrol after it comes out the same tap?

it is but i doubt the likes of shell etc will share the lastest info with the likes of tesco, asda etc, so i think its fair to say that the major oil companies will have better fuel then the supermarkets
