Yes the fact that the 2T oil burns hotter and cleaner than the Diesel was why i thought it would be cleaner and not cause a increase in gumming & soot. I used to use alot of 2T oil in the past with the motorbikes, but i would never use anything but the best fully synthetic stuff and always the same stuff never mixing. So the mineral must of been invented for us diesel boys to mess about with coz it only blew up the bike engines really quickly as it was the only lubricant for the whole engine and alot of people skimped on it, but fine for the diesel me thinks.
2T oil is expensive enough, even the mineral stuff when you consider you are just burning it constantly, but 90% off injector cleaner isn't cheap and usually crap made sound good.
It works out for me about an extra 83p per full tank, not alot if it brings most of the advantages it's meant to, especially for extra reduced wear on those pricey pumps and injectors etc.It might give it that hint of 2 stroke smell also hopefully lol.
Iv'e 5l ordered of Comma mineral low ash 2T, will report back my findings along the way.
