Wynn's Diesel Injector Cleaner Engine Fuel System Additive Treatment 325ml

My car's old diesel engine occasionally needs some TLC and for a variety of reasons I couldn't get my usual additive so took a chance with this one. Really impressive results within a few days of running a full tank...much smoother and more punch on acceleration. Also passed its MOT with no emission problems. Will be buying again.

Good product, I’ve used it many times times on different vehicles

kept my 170000 mile injectors going for 2 more years

So writing this review almost after two months since I added the cleaner to my car a 2012 passat tdi i have always used shell vpower diesel for my car since i bought the car a year ago,so coming to the wynns injector cleaner i filled upto 50ltrs of diesel and added the cleaner as recommended ,you wont feel the cleaner working straight away but personally i felt the car started running smoother as the days go by and starts like a brand new car in any sort of weather after 10-15 days it did have a bit of white smoke at start like after 5-6 days after i added the cleaner but with the right quality fuel according to your choice i do believe the product does really good.Also i did feel a mileage increase not a huge increase but noticeable.Will buy one more to treat the injectors one more time.thanks wynss for cheap and effective injector cleaner.super happy with the purchase

If your like me and read some reviews online with people saying it doesn't do anything and it's snake oil they are incorrect.I have a range rover and it was a bit hesitatant on acceleration and noticed it was getting quite loud on tick over.I put this in with a full tank from costco and I found some instant results the engine is quieter and the hesitation has reduced its only been a couple of days so when I've done a few good runs it should clear.Will be doing this at least once a year.

This worked wonders for my car. I have a diesel Renault Kadjar and the check injector engine management light came on. I used a full bottle of this on a full tank if diesel and the problem cleared itself within 2 weeks. Didn't need to do anything else. Saved a fortune on potential garage costs.

Mileage, sheerness and thickness? Wtf?I used this stuff (with 20 litres of Shell V Power diesel) and it didn't make much difference but then I doubled up on some other stuff (2 x Liqui Moly Super Diesel Additive Injector Cleaner 250ml with 30 litres of Shell V Power Diesel) and there was an immediate change, this stuff may have loosened the crud ready for the double bubble of other stuff to do it's job? It was funny that there was an instant improvement when I added the other stuff and now that I have filled up with standard diesel (77 quid!) it's still fine!The Barge (Mondeo Estate with a 1.8 TDCI = big and slow! 😀).She was juddering more and more, been an issue since I bought it 3 years ago, I did treat her a year or two ago with a cocktail of stuff from Halfords which improved her for a while!Not done many miles since I filled up got the Esso good stuff for not a lot, I was previously using supermarket fuel but I've found a cheap Esso garage so I'll continue to use the Esso Premium diesel from now on!

Smoother tick over after start, slight increase in power
