ive added the forte fuel add to both my merc and the MG, noticed the MG blowing a bit of crap from the exhaust after adding and a run, started to panic, but now its fine, could have been the additive burning or the crap build up being burnt off, FORTE have a very good reputation and seem to know what they are doing, I think if you want to spend on "expensive" fuel then shell V MAX is the only one to rely on for being quality.
