Mannol Engine Motor Flush 300ml

Did this while replacing an oil pressure sensor and filter change, oil before I started wasn't too dark only about 6months and 5K miles old, added this straight into the engine didn't drain and re pour in, ran it for the time specified on the back of the can and then when draining it was consideravly darker. Also peering in the top of the timing chain cover was visibly cleaner than before so I reckon jobs a good 'en, very effective. When the new sensor and oil etc was put in, the engine was noticeably quieter at idle and also while driving normally to 30mph. Not scientifically tested, could be in my head. Can't complain about the price either, cheaper than other brands and worked just great

I use this every service time gets all the gunk out of the engine

Ok flush.

Mannol are decent products a lot cheaper than counterparts. Therefore i can afford to half my oil changes to protect my engine and not have to pay £50 - £60 for oil every oil change.

Did the job and only left running for 10 mins with the product in.Used 1 can for 7 litres then changed my oil and filter.

This kind of thing im usually skepical about, you can’t usually see any improvement. This is definitely not the case here. I used it on my 09 Audi a6 tdi, very overdue a service with the blackest oil ever, stained anything it touched.Followed the instructions, didn’t think much of it. The black liquid that came out did surprise me, but I was not expecting to be able to see the orange colour of the dipstick through the amber oil. This is something I’ve rarely seen having had diesels for years, even with services every 10k miles on cars I’ve owned.I am truly blown away by what it’s achieved in such a short time. Not a silver bullet, but very close.For the price, it’s going in any future oil changes.

Does what it says on the tin

Only 4 stars because there can opening like on fish can which broke and I needed cut to open and half content split, even with half it done excellent job cleaning engine, I done now few hundred miles on diesel big engine and still oil transparent
