Tesco Petrol
before I start, yes I did put the right bloody type of petrol in, I am not that much of a fucking idiot.

Has anyone in the last couple of weeks filled up with Petrol from Tescos, especially in the cambs / suffolk area and found the car to be shit, sluggish, stalling and mis-firing horribly?

I slung in £15 at Esso today and now its fine, but that last tank of fuel was shit!

Didn;t this
happen about a year or so ago with pumps form Tesco being sabotaged?

half of the pumps at the station were out of order

My wife refuses to fill up at tesco
because she says her car does about 10 mpg less, stall a lot and forgets how to go uphill.

I think shes talking bollocks personally

I don't know about over there...
But on this side of the pond, if the ground tanks the gas is stored in and pumped from aren't regularly cleaned and maintined, they build up all kinds of sludge and grime. Each time a truck delivers more gas, it stirs up all that grime. If you fill up around the time of the delivery, that sludge will get in your tank and significantly reduce your performance.

So the moral of the story is: never fill up within a few hours of a tanker delivery. Try different stations and pay attention to your car's performance on that tank of gas. Eventually, you will find a station that maintains their pumps and you shouldn't have any problems.

There are also additives you can use to improve performance.

I got lucky. The most well maintained tanks in town are at a gas station that also has some of the lowest prices. It is only 5 miles out of my way, but well worth it in the long run as it saves me on maintenance.

Edit: I can't believe a GIRL was the first to explain your problem. You guys should be ashamed of yourselves.

For some reason
if I fill with supermarket fuel, I'll get around 18mpg.

But if I fill at Shell (and not even V Power, just the normal stuff), I'll get about 21mpg.

I've repeated this experiment many times, and it's different to the point that I can tell where it's been fuelled even if someone else has done it.
