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.

I have use Liqui Moly other products but never this octane booster. I bought this to try as the petrol in my boat is a bit old. Holly Molly, the difference is instant. No more smoking fumes out of the exhaust and the engine sounds very different. Bought another can just in case.

Ok

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.

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.

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.

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

Cok iyi ürün

Come tutti i prodotti di questa casa eccellente

The product delivers what it claims. Smooth acceleration. Increased punch. Amazing pickup. Engine sound decreased dramatically. Loved the product.

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...👌🏁✨️
