If you have ever driven an old transit you will know how noisy and rattly they can be with age. A top tip for an old ford transit is for every tank of diesel you put in, put a bottle of two stroke in. makes it run quieter and smoother. it helps lubricate the parts of the engine that the engine oil doesn't. fuel pump and the likes.
modern fuel can be quite hard on new engines. supermarket fuel is terrible. cheap and nasty. the dregs.
and modern engines have to meet strict emission laws so the engines are restricted and use silly EGR valves.
using additives in your fuel help lubricate fuel pumps and also help give your fuel a bigger bang, or a slightly higher octane level.
this helps getting rid of the carbon build up. (waste gases burn hotter with a higher octane)
your car will run quieter, smoother and also feel a bit nippier.
I have used Millers for years, my old isuzu trooper loves it. and so does my berlingo.
If you're in doubt, nip to halfords and buy a bottle of Millers, it costs about £13 and will last for a good few fill ups. (there is a petrol one and diesel)
but, if your the sort of person that fills up at the supermarket. don't bother.
and i wouldn't bother putting 2 stroke in your car either........
