Ok, more info should be provided.
Background story: a week ago I got the car and when I was cleaning the engine compartment, I accidentally unplugged the large radiator fan. Then I did some offroading and it overheated to 130 celsius. I immediately stopped and waited for it to cool down. No smoke was coming out, everything seems fine. Now it sits perfectly at 90 celsius, so my guess is that the head gasket is fine.
Two days ago I filled 20 litres of OMV Maxx Motion premium diesel. After a few kilometers I felt a change. Before that, if I put the pedal to the metal the front end would rise and the car would take off. Then the power delivery got more linear and it felt lazier.
I burnt all the fuel that day.
Yesterday I got 40 litres of Ecto Super Diesel from Lukoil (I only buy from Lukoil usually, the OMV fill was a mistake). Now the car is awesome again, flooring it feels like getting punched in the face and it's all great.
Today, it started to get lazy again. Same fuel in the tank that worked great yesterday.
Could this be caused by contaminated fuel? If so, what do you recommend? (I know above I said bad fuel is not the case, however it is too strange of a coincidence).
