Add 250ml of stroke to every full tank of diesel.
Works a treat on mpg and engine pulls better at low rev's.
Is that 2 stroke oil? Interesting! What sort of improvement would be expected? Sorry I'm bit new to this, only had my 90 7 months now and learning everyday.
2 Stroke works, it lubes the injector pump and other parts too, use low ash type, have used it in mine from the start and passed MOT emissions tests with apparently very low readings, not bad for 28 year old original motor!
