Great products that work as advertised
I've been using the products from this company and nothing went wrong so far. Overall, I am satisfied.
Perfect for engine maintenance..
Great product
My Pathfinder love this stuff - has never run so good!!
My utes definitely run smoother& use less fuel with the decaboniser 👍
I bought the Fuel additive and decarboniser bundle and can report that in my Renault Master I noticed a near immediate increase in fuel economy. The van was spitting out all sorts of faults from low boost pressure, H2os sensor out of limits etc. and now they’ve stopped too. The van used to even spit out the odd injectors fault code too. I did notice the van was running at about 60° coolant temp so I replaced the thermostat before trialling the cost effective products and not a single fault has returned in the three weeks I’ve been using them. The van has only ever had premium diesel out through it, and I’ve just passed 500,000 kms. I wonder how much more I’ll get now that I’m running the additives and if you guys want to get hold of me to keep you posted, feel free. Chris
Delivery was quick and packaging was very good.Products looked very good quality and are easy to use.The explanations and instructions for why and how to use,mixing charts etc are very good.The Triton is running well with no issues.
good products speedy delivery
So far, one tank of double strength and now starting second tank of single strength, DPFmight be working a little better but no noticeable differences overall yet. Have had blocked EGR programmed out and that has made a difference to soot production. So possibly too many moving parts to determine the effect of the additives. What I probably need is to have the inlet manifold cleaned out.
it just works !
Great product it will save your coked up piston rings gas or diesel
Been a customer for over 10 years using the CEM product range on both petrol and diesel vehicles and apart from routine maintenance, the vehicles have run faultlessly.
Snake oil. I originally bought this product to improve the performance of my Kia Carnival, 2.2 diesel engine with 200k on the clock. I really didn't feel any difference or improvement by using this product. I wish I could return it as they are promising the world when they are selling it

Double dosed first 2 tanks Hilux was getting delayed pickup when taking off & has improved 100% since using this product , very happy so far
It has helped my Jeep Cherokee 1998 diesel comeback to life. It used to have sluggish performance and the engine suffered from servere blow by. Now, after on bottle of DeCarbonizer the performance is much better. I recommend this product.
These products eliminate the need to do a exhaust regeneration process on our Mercedes diesel which does mostly city driving. Simple and effective.
