330CDT Posted February 20, 2016 Report Share Posted February 20, 2016 (edited) Granted..... I've been seeing so much of this topic pop up recently and wondered if anyone's got any (expert) views on all these additive type products; This 'millers' one below has tons of good reviews on amazon: http://www.amazon.co.uk/Millers-Oils-Diesel-Power-500ml/dp/B002WCAISS/ref=cm_cr_pr_product_top?ie=UTF8 From what I've been reading the TL;DR is if you use V Power / premium fuel the cleaning properties can help. If you add these additives to normal fuel, it's cheaper in the long run and you get the same benefits. Just something doesn't sit right with me and I'm in the 'It's a con!' corner. Fair enough if your having EGR / DPF issues and want to bung some in for a try, but some of the reviews on there are using this every tank and claiming better MPG? Surely the car is not designed to be running this through it's tank in the first place? Would just be interested on any solid information / claims / opinions on the matter! Oh and also, from the plethora of 'cleaning' type products available, should I be considering any e.g. 'turbo cleaner' or 'injector shizzle' as my 330cd is coming up to 135k. Car is running healthy, good MPG but do get some smoking on full throttle. If it ain't broke, don't fix it comes to mind but I'm interested to find out more... Cheers!
