Due to the distance between the valves and the pistons the use of an additive which decokes the engine is not advisable on TS, JTS or V6 engines. I've just finished rebuilding a V6 which had a lump of carbon break off in the #1 cylinder, this was found during a cambelt change, this little lump 4x5x5mm was enough to stop #1 passing TDC by hand, as the engine had more power and it ad been like this for a while, the big and little ends were flat spotted and causing a knock, this also resulted in piston slap, requiring the replacement of the big end shells, conrod, piston, liner and rings, as well as all the gaskets and fluids involved in removing the heads.

The morale is that the twinny has even smaller tollerances and flatspotting a big end shell on a TS almost always means changing the crank.

I've never used any.

If it ain't broke, don't fix it.

Which? magazine have this month tested various fuel additives and, at best, found no significant change.

Therefore they are a waste of money. And in my opinion too.
