The day after my 1st covid jab I filled up with the wrong fuel only noticing as I replaced the green handled pump.I can't explain why but I was feeling fuzzy headed.I moved my 2 seater TT to the supermarket car park and googled for assistance.Fuel Fixer responded quickly and on time.Due to the type of car the mechanic had difficulty locating the fuel tank access plate,so a work around was done at the engine end.The car has been fine since.I still have another covid jab to go-might see you again! s
