Caterham, sorry I wasn't really replying to your comment! Yes ultimate/vpower are definitely better and will give a choked up engine a clean out for sure! Shouldn't do anything an injector cleaner wouldn't do though

As I said standard diesel (even in the UK) is just a little bit poor spec compared to the high tec Diesel engines we have nowadays, gone are the days of indestructible diesels which will run on parafin etc!
