Used on a very rough sounding Land Cruiser. The difference in the engine is amazing and you could notice a difference within 10 miles. After 100 miles the engine diesel knock has gone and it sounds so smooth, almost like new not a 120k engine. Starting from cold in better and the MPG seems better as well. Should have tried it years ago.

Have a VW 2.0TDI and the flashing coil light followed by eml light. Fault code EGR valve. Put this product in and ran the car for approx 30 miles. Returned to car, all warning lights are now off and have remained off. Would recommend before having to replace egr valve as it is well worth a try. It worked for me.

My Mercedes Sprinter running crap due to lack of mileage through lockdown. Went into limp mode twice. I put a full bottle in with about a 3rd of a tank of fuel as advised on a lot of forums. Took it for a 90 mile motorway trip and the change is amazing. This is to a well serviced van with new injectors fitted 2019. Runs smooth with the throttle flat spots gone. I highly recommend this product.

Have not looked inside the turbo before and after usage, but probably works. it is a satisfying feeling that I atleast try to maintain my car.
