With modern Diesel engines, the need to keep the injection working well is always challenging but this product if used correctly should improve performance..I used half as had an issue running a VW PD engine after a fuel pipe had ruptured and running rough a 1500-1800RPM .The pipe was only 4" long but has not run right since .I have used 500ml of this product and has indeed improved matters but also in the process of running this and changing the fuel filter found another fuel pipe and return pipe not so good so replaced.The Van is 12 yrs old but still a great Caddy although unusal fuel disrbution in a PD ENGINE and better understanding would warrent more of this super juice .A recomendation is NOT to put this in the tank but run straight from the can ,some would use a glass jar with return fuel back to the can.It does get hot as heats up with the engine so hoses can get squashie Cable ties help.A look on youtube helped with a small list of things .I will be using again as a great product ..Vorspondure tecknek Read full review

Ive used stuff the last three years and its kept my astra running sweet it's on 190000 it's part of my service now and peace of mind. I don't purge I just put it in filter chamber and rest in 1/4 tank run till fuel light comes on then fill up as normal. Car now runs as good as ever well recommended for old arthritic diesels like mine. This stuff does work otherwise I wouldn't use it. It doesn't repair broken injectors it sorts injectors that are not spraying properly by removing carbon deposits and keeps fuel lines tip top.

I have use this product a lot I put it into my Mercedes c class as the engine management light came on the man at the garage said it needed a new part (sensor in the exhaust system) but with just over 12,000 miles I did not agree so put liqui Molly in 500ml in a 3rd of a tank of diesel and in about 50 miles the light went off and has stopped off

Bought this for my 07 plate 2l x type jag which was smoking on start up and suffering low load diesel knock. I transferred it into a clear bottle so I could see what was happening better and to make sure I didn’t run the fuel pump dry. Took about 20 minutes start to finish. Wow! What a result. No knock at all. No smoke on start up. I’m easily impressed and this didn’t disappoint

Best to use a filter on return and your get a good result all round. better than cleaner off shelf as gets to diluted!! do as it says on can, and your be pleased with result. 500 is enough for small diesels as it will take 5mins at least to run through. cleared a few diesels and it done the job nicely.
