JLM Engine Oil Flush for Petrol & Diesel Engines, 250ml (J04835)

The product has made a difference in my old Vauxhall combi van with 120k miles, 1.3 diesel turbo, so not quick! it used to stutter and lose power at 2500 revs then pick up, but now its improved still not 100% but much better, as this tank of fuel runs down I would hope I see further improvements. I know there is something else wrong, sensor or injector needs changed but this stuff appears to have cleaned the system out. What I cant say is how it compares with other similar product that are cheaper

not bad at all dos the job

The product initially I sought a bit expensive after a week it thoroughly cleaned my DPF which was in a bit of a state would recommend this products to any diesel owner's and also cleans injectors

This stuff is expensive. First impressions count. The spout on this can is lousy and there is a lot of waste. Worse, the can cannot be emptied.This fluid needs a decent way of getting is into the tank and it neither provides or suggests one might be needed.If you buy this, get a decent funnel, you will need one.

Easy to use. Put it into my tank right before filling with the light on. Gave me an extra 5mpg in my 4wd auto Volvo xc40. Maybe not quite worth the big bucks but nice to know it’s clean in there now.

Serviced car first then put this in a tank of fuel and pre service was 30mpg after service ran for one month and got 34 mpg then added the treatment and after one whole tank I’m now getting 43mpg, definitely works and better than the cheaper stuff! Product is proof of paying more for better quality!!

Made no difference at all

I havent noticed a difference in engine performance or mpg change but additive or cleaners are alway good to test and try
