Must have for large diesel SUVs
Must use product for people driving Diesel SUVs. All your Fortuner owners, try this. I have a 2020 BS 6 Ford Endeavour. Of late, the vehicle sounded that engine was really working hard - both on highway and in city drive. Used this product after filling the tank full and within few kilometres, the difference was apparent. There is visible improvement in engine performance, reduction in noise level and very smooth driving experience. It is specially recommend for people driving large diesel SUVs and before winters sets in. Just ensure that you full tank before using this product. This is way better than System D.

Wow car became butter smooth
I have poured entire bottle into fuel tank and filled tank full diesel. Just in 10 to 15kms, I started to see engine became quiet, very smooth Buttery feeling, this is a wonder additive. Only Con is that... engine will be back to normal once the fuel is over.. This will be an expensive affair to put 600/- worth additive everytime you fill fuel.

Boosts throttle response and smoothness.
Just go for it, got great results just after driving for around 5 km, on my 1.5 Figo, which is clocking 50k km.

Dachte an Hokuspokus aber das Zeug hilft wirklich!
Also ich habe es bestellt und dachte Hokuspokus , aber nein ich habe es bei unserem Kia Carens RP Bj 2014 mit Euro 5 140000 km ,angewendet und muss sagen ich bin fasziniert, beim Starten ruhiger Lauf , beim fahren war im 2&3 Gang immer ein Teillast ruckeln bei ca 1750 - 2000 min-1 da brummt der Motor sehr stark komplett weg . Auf der Autobahn bei 120km/h läuft der Motor sehr viel ruhiger, Wahnsinn was LIQUI MOLY da entwickelt hat . Nach der ersten Tankfüllung mit Speed tec Diesel , zeigte der Bord Computer einen Verbrauch von 7,5 Liter an, war davor immer bei 6,5 Liter festgenagelt ohne Liqui moly Jetzt ist er bei 5,7 bis 5,9 Liter und das durchweg , ich glaube es bringt wirklich was, der Motor Lauf ist um einiges besser geworden.

Good quality and value
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.
