Somebody at some point is bound to say the injun becomes addicted to it, an as far as I'm concerned it's a load of bollox, how can an inert object become addicted to summat. If you find the reason you needed to use the stuff in the fost place as Yella sez like yer glowplugs or wiring to em then you shunt have to use easystart. An while we're on the subject an if you dont get it sorted, try using brake an clutch cleaner, when I tried it it was miles beterer than easy start, but dunt smell as good.
