I was really impressed with them today to be fair, a little p1553D at myself to though. I filled up with V Power, literally a full tank. When I arrived I told them but also said it would normally run on standard fuel.
After they discussed it amongst themselves they decided to drain my full tank of fuel and take the car out for a quarter of a tank of standard Esso fuel. Bit gutted I wasted all that fuel though
I must admit, it’s the first time I’ve ever heard of somewhere going to such extreme measures! Just goes to show I suppose that they do truly customise the tune to your car, rather than just loading on a 95 RON file and smacking you on the **** on your way out through the door!
I'm very pleased to see they offer a 95RON solution as the gains are still immense but with a measure of practicality. Some places super is hard to get and expensive. It's a worthwhile trade. Plus I've had a fuel card in the past so know the restrictions that places.
