Liqui Moly Speed Tec Benzin Petrol Additive (250 ml)

First thing is performance jump is evident in direct injection engine only... do not waste money in using in naturally aspirated engine... max it will just clean injectors and intake port in NA engine...But in tsi or gdi engine this when mixed with petrol gives tremendous performance jump and mimics like octane booster... it contains nepatha and nepthaline which are true octane booster... my advice once use in above mentioned engine , you will surely start liking your car and driving

Good . slightly fill speed .

This makes your vehicle combust the fuel efficiently, even if fuel is days old. I have tried it with fuel injected as well as carburetted engine. This not necessarily increases octane number but makes the fuel combust near its stoichiometric value. Even better mileage becomes achievable as combustion reaches near stoichiometric value and with good driving habits.Engine becomes smoother to operate, engine revs smoothly and overall driving experience becomes more enjoyable. Do note that: THIS IS ONLY FOR PETROL ENGINE.Highly recommended but do check it being genuine.

Not required, until unless you have some serious problem with fuel system.

One of the best product you can use for your car if you are car lover and likes to drive. Can recommend to others.

You can feel the difference from first kilometre itself. There was a considerable improvement in throttle response. Having said that, I could not feel the real punch of it as my car was auto gear (cvt). I felt, The computer sitting behind was engaging clutch as it couldn't handle the sudden acceleration caused by this additive. Apart from acceleration I also observed that the engine went lot more smoother.Very effective one but was too good for my CVT.

Used it once for 2 full tanks. Used it for my 2014 i20 elite petrol. Haven’t noticed any noticeable difference.

Tried it on my 5.5 year old Hyundai i10 1.2L Kappa. Normally i get a mileage of roughly 420km with a full tank of petrol during my daily commute. With this added, my mileage increased to roughly 460km. I measure from reserve to reserve and reset the trip meter. This was an amazing 'sideeffect' and something i didnt expect at all. This product doesnt claim that it will extend mileage. The engine performance in lower RPMs seem to be slightly better. Overall i'm very happy with this product. Will definitely recommend to everyone with petrol cars.NOTE: I'm in NO WAY associated with this company or any of its dealers. I PAID for this product and bought right here in Amazon.in. Thanks.
