Hi All,
Since I bought my 2018 Insignia B 2.0 at 40K miles, I have been using cheap and cheerful supermarket diesel mainly from Tesco. So far I have covered about 25K miles within last 2 years in this car. About 6 weeks ago the engine management light turned on. I ignored it because I assumed that my insignia needs some motorway mileages for a self-clean. Then, about two weeks ago an amber light started turning on while driving. The light was showing a car and skid marks. There was a message "engine power is reduced". And there was a significant loss of power. It was like limp mode. Every time that light turned on, a restart cleared it and I kept driving like that for about 2 weeks. Finally, yesterday another light turned on but this time it was in my head! I filled up the tank at a Shell station with V-power diesel. Within a few miles engine power reduced sign disappeared. After about 100 miles usage in two days, engine management light turned off. The engine pulls like a train and I feel epic again! I am really wondering if I was on the wrong type of fuel (that is Tesco diesel) since I bought it? What fuel do people use?
Cheers
