Supermarket vs. branded petrol.. your opinion?
 

I know its a controversial subject, but there seems to be plenty on either sides of the argument. I recently tried Shell petrol instead of ASDA and I've got around 30 miles (67mpg according to fuelly) more out of a tank than I usually would - however I was behaving myself on the motorway!

Whats your experiences guys, or do you just go for what's cheapest?

Supermarket vs. branded petrol.. your opinion?
 

I much prefer branded, I filled up at morrisons once in my car and it stalled my car and put the EML light on.

Apparently most supermarkets buy there fuel from random sources generally in a auction and the addetives aren't great and can make for rough running

On road machines where they will take anything, I don't find it makes a difference. I generally use Supermarket fuel. I don't find it makes any difference whether I use a brand or not. AFAIK, most supermarkets buy from a brand.

I use pretty much anything in the car, but will try to use branded in the bike. I avoid Texaco at all costs as had a bad experience with their fuel which nearly made me come off.

Must admit my diesel fumes smell funny, I always fill up at Morrisons.

Smells of kerosene, like its been watered down with a cheaper but combustible substitute.

Supermarket fuel is the lowest quality allowed under British and EU standards. Has less of the additives that improve the burn, emissions and quality control that the branded forecourt fuel has

I found when I had my SV I'd get up to 40 miles extra per tank, however not each ride was the same.

However I noticed this also happen on my ZX6R, it was also more responsive.

I ran my Clio on Shell fuels, and generic supermarket fuel to test. I do the same drive week in / week out, of pretty much all motorway driving at 70-80 for 100 miles per day (50 miles each way). All year round, I found I got an extra trip in (50 miles) before my petrol light came on when using shell fuel that week, every time. I won't use anything else now.

Yeah, I read a lot about the big supermarkets buying from shell and the like - and the difference being the additives added at the forecourt. I guess it's all about how temperamental the engine is - I can see small honda's not making a difference, whereas infamous italian brands being a bit iffy haha

Nope I will not buy Tesco fuel as its so poor my bike runs like a bag of hammers
99 Ron is slightly better

I think what they do they buy from auction and using food as a comparison supermarket fuel buys from the discounted section on the best before date and add additives which makes my car runs like a bag of spinners compaired to shell or bp which are the only two i use mainly.
