Thanks @kezo That’s very useful. I’m not going to buy a car like that and worry about running costs, but if I decide that I’m going to keep the car long term then I want to give the engine the best chance of a trouble free life!
I’ve read a lot of stuff on this issue this evening (since my earlier post) and Tesco Momentum seems to get very good reviews, with Shell V-Power being deemed better again but primarily due to additional additives, which chimes with what you are saying.
I’m not going to have the car until the summer, so hopefully fuel prices will have settled by then 😂
