Almost
Diesel SVO you should build up the ratio slowly....main issue is that SVO has a habit of making any existing problems worse. MY truck runs better and quieter on 50/50 for example,
while Extremes runs a bit rough....
Acetone needs no build up period.....google 'acetone in diesel' for alleged benefits.
I stick approx 150ml every time i fill up. I suggest you buy a small amount though to start with in case you think its a waste of time...but full whack immediately and it takes a tank or two to start to feel the benefit, but its like using premium fuel IMHO.
