Speed Tec Diesel | 250 ml | Diesel additive | SKU: 3722, k.A.

I’ve been very pleased with this product. It arrived on time, well-packaged, and in excellent condition. The quality is solid, and it performs just as described. It’s clear that attention has been given to both design and usability. What I appreciate most is the balance between quality and value — it feels reliable and worth the price. I’ve had no issues so far, and it has met (and even exceeded) my expectations. I’d happily recommend this product to others who are looking for something dependable and effective.

Hi I'd tried a multitude of treatments for my Diesel system, after the LIQUI MOLY was in my tank, it took only a few days to feel the speed and power coming back:) I'll be treating as recommended from now on:) BUY !! great price too

I don't know but, maybe not only me feeling his/her car after this liquid feels a lot lighter, even without hard pressed acceleration pedal, runs smoothly and achieving fantastic mpg, am using on full tank 80l of diesel and it's a really a quality product.

Seems to do what it says on the tin , made my VW TDI seem to run slightly better , but that may just be phycological thing , didn't seem to make my mileage go up , but again may work better over repeated use for a long time , who knows if any of things actually do anything major ?

How do you review something when you have no idea if it worked? The Liqui Moly brand is excellent and I won't use anything else. They're great value for money when you consider the high quality product you're using. I'm sure this product is no different.

Car running better does the job

First time i used it in my Hyundai Tucson 2019 model and just after poured it I feel massive boost in acceleration. Now, I will use it every time. Thanks

Great product but not a great idea for the packaging
