Liqui Moly Speed Tec Gasoline | 250 ml | Petroladititive | SKU: 3720

I've been using this for a while in my SEAT Leon Cupra 300. After 6 cans (6 full tanks) I switched back to just regular fuel for 4 more full tanks. There is definitely a clear difference in engine noise, and performance after driving several hundred miles with/without SpeedTec. The acceleration is definitely improved in the mid-range. It pulls harder, for sure. And the engine appears to run a little bit smoother. I use one can of this mixed with a full tank (50 litres) of Shell V-Power fuel.

Whilst not able to provide empirical evidence, I am happy that the use of this additive is (seeming to) improve the smooth running, acceleration/pick-up and efficiency of my car engine.

Very good product. I recommend the seller. Fast delivery, everything as described. 100% satisfaction.

I used this in my BMW Z4 E89. The car feels more responsive and the engine smoother. I don't know if it is any faster , but I liken it to when the car has just had a full service. For what this costs, I think it is good to use every few months.

My car, a Prodrive tweaked Subaru WRX, is tuned for 97+ Ron super unleaded fuel and if I use standard unleaded the ECU detects knocking and retards ignition, which makes it hesitant and sluggish. Sometimes I have to reset the ECU once normal fuel is back in after using standard fuel. It’s even done this sometimes on certain brands of ‘super’ unleaded, so I generally stick to Shell or one of the supermarket branded 99 Ron ones that I can’t remember the name of as I’ve found those reliable. During the recent UK ‘fuel shortage’ I could only find standard unleaded, so I bought a bottle of this to see if it would help, and surprisingly it did. It’s not as smooth running as when using Super, but it’s close in performance and seems to have prevented retardation. I really didn’t expect it to work being skeptical of such ‘snake oil’ additives, so I’m sure it’s not a placebo effect. I’ll get another bottle of this or another brand and keep one in the car just in case I can’t get super again. Wouldn’t bother adding it to super though, it’s neither cost effective on any fuel nor necessary on the right fuel, at least I don’t think so. As a ‘snake oil’ convert I’m now thinking I should get a fuel stabilizer for my camper van as it sits for a few weeks unused and a tank of fuel can take all winter to use up.

Ok

Didn’t really notice any difference and is expensive. Will stick to redex when it’s on offer most times at the supermarkets. Think the brand name attracted me to it as LIQUI MOLY is a good brand.

What difference in my daughters 30 thousand mile Clio. Running much quieter and smoother acceleration

Si se nota el motor esta mas estable pero potencia no note nada

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.

Top, wie Alles von Liqui Moly. Ich hatte mit meinem Suzuki Swift Sport Hybrid Leistungsprobleme. Nach mehrmonatigem Tanken an einer No Name Tankstelle hatte die Software des Fahrzeuges die Leistung reduziert. Der Wagen lief keine 200 Km/h mehr und stotterte über 5.000 U/min. Die Software schützt so den Motor. Jetzt habe ich dieses Additiv mehrfach einem Markenbenzin beigefügt und nach gut zwei Wochen wieder volle Leistung erhalten. Hat geholfen, dass sich die Software rekonfiguriert hat. Jetzt läuft Er wieder knapp 220 km/h und beschleunigt besser. NIE WIEDER BILLIGBENZIN, JEDOCH JEDERZEIT LIQUI MOLY...👌🏁✨️
