Liqui Moly Speed Tec 3722 Diesel Additive 250 ml & 1803 Injection Cleaner 300ml

Really love this product the improvements in performance and smoothness of the engine make it a must have i will continue to purchase this product

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 ?

This product treats one tank of fuel but does increase power and reduce turbo lag. I will buy it again. I probably won't put it in every tank because of the cost.I'm don't think it helps with mpg, but it does seem to help power

Ok

I have added this to a full tank of diesel in my honda CRV and haven't noticed anything substantial to mention about the product. In time maybe it will improve MPG and clear out some deposits. Very easy to use,just pop in into a tank and fill up. I think if you use the motorway a lot then this product may work quicker with more noticeable results.. haven't noticed any changes in power delivery. Would I buy it again! Well,maybe after I empty this full tank.

I always buy these products for my car they work great then have looked after the I internal parts well. If it's good enough for f1 it's defo good for me..

This stuff is really good. Seen a difference quickly.Van runs much quieter and seems more efficient
