MOT

MOT day today so cut through the park to get to work after dropping the car off.

Had the same conversation with the garage chap about supermarket fuel being really bad for the car. Is it? I have no idea. He mentioned about elevated hydrocarbon levels (ours was 25ppm when the limit is 200ppm, hardly crazy). I’ve googled and YouTube’d but most say supermarket is the same as branded so who knows?!
