I've just got some of this,(one of many write ups, this one from the MG owners club) from what I can work out, if you are going to use an addative this is the one to go for. Originaly recomended to me by Jules at KK. I got the regular not the plus as the leaded fuel of the time only had an octane number of 70 so to boost the current 95 unleaded is cirtainly not neccesary.
£10 for 250ml that treats 250 litres (1p/ltr).
If original VW engines were ok for unleaded, why do they now sell 'unleaded heads'? just a thought.
Thought I'd be better safe than sorry, can't do any harm.
