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
Momentum99 – supplied by Shell and Greenergy (part owned by Tesco),
V Power – supplied by Shell and Greenergy
Shell & Greenergy co-0wn facilties (part owned by Tesco) that produce Tesco Momentum 99 import and store the same base petroleum as V Power, They are both 99 ron minimum in the UK. There are secret detergents and additives and octane boosters added and Ethanol.
Shell the glamorous one with its red flashy brandy and a marketing department happily tell you that V-Power has more detergents than a box of washing powder and is derived from the same technology they use in Formula 1, which is al very impressive until you remember that F1 cars get rebuilt after every race. Whils’t Tesco the dark horse of the premium fuel world are more interested marketing a bargain on tinned beans, whilst quitely promising big performance and high RON numbers, all for less money than the other big names. Make of that what you will!
Esso Supreme- produced by Exxon Mobil, with ethanol added to it (depending on which part of the UK you are in). A marketing department who promises double detergent additives & a friction modifier similar to Shell. Also supplied by Greenenergy in some parts and premium E5 97.
BP Ultimate 97- Prduced by BP, with ethanol added and marketing department who will shout its the best, taking care of engine more than others. BP’s game isn’t about brute power, having gone for a different angle. Ultimate is packed with additives they call Active(s), which actively work to scrub out nasty carbon deposits in your engine, like a magical brush for all 8 cylinders. Perhaps best known as the caretaker fuel that too over 5years to develop.
I’l await to see more testing as time goes on to understand the full impact of the trade deal, giving it time to settle down and what parts of the country are affected most, rather than taking one off’s as the happy nedium. 1,5% ethanol difference is negligible between the two tested and within upto 5% total allowed. Personally I’d run it on the cheapest of the premium fuels you can get locally.
