    Rated 4 out of 5 by Very Good Product Used this product in my 1989 Mini Flame, just follow the instructions on the back if you have limited mechanical knowledge. I was suprised to see how much sludge came out of my sump and i change my oil every 4 months and have never seen the same amount of rubbish flow out, so i can only imagine that the product has done its job 23 April 2011
    Rated 5 out of 5 by Brilliant stuff. I have used this flush on my Volvo xc90 d5 car 3 time's now and every time it really really clean's the inside of the engine brilliantly before an oil change. A lot of people are scared to use a engine flush especially on a old or high mileage engine but i have not had any problem's using this and i will continue to use it. 20 November 2015
    Rated 5 out of 5 by very good made difference after few weeks service engine oil still clear it got rid all old oil from engine 05 October 2015
    Rated 5 out of 5 by Good product Have used this twice on my 1.4 tsi twincharger, does a great job of removing deposits around the engine - i only had to look into the oil filter hole after letting it drain for 30 minutes, to see how clean things were. Unlike some other engine flushes this one doesn't contain solvents, but only detergents and anti-wear compounds. This makes it one of the safer engine flushes on the market. The flush was used to solve a common problem with my engine and the tiny passage ways on the camshaft adjuster gumming up and sometimes resulting in the adjuster sticking for a moment on startup. 31 July 2015

    Rated 5 out of 5 by Was dubious,- But results outstanding! I've never used this product before, but, as a vehicle in our fleet has been overseas, and travelled 30'000 miles without a service, I knew the oil would be bad. I followed the instructions, dropped the oil, which was possibly thinner due to adding this product, then changed the filter (Which was in a bad way). I dropped a few extra litres of new oil through the engine to get rid of residue, replaced the oil drain plug, and topped up. The car ran like a dream, and there was definitely a difference in performance. Additionally to this, both air and fuel filters where changed, which also would impact on the performance of the vehicle, however, I am most pleased with this product, and will use it more often! 04 January 2015
