LIQUI MOLY Oil Additive | 300 ml | Oil additive | SKU: 2591

I’ve been using LIQUI MOLY Oil Additive 300 ml in my car tuning and workshop business for months now, and it’s genuinely impressive. I’ve tested it on a wide variety of engines — from everyday vehicles to high-performance tuning projects — and it consistently delivers excellent results. The additive improves engine smoothness, reduces friction, and helps keep even older engines running efficiently. I’ve noticed quieter operation and more responsive performance after use, which gives me confidence when returning tuned or serviced vehicles to my customers. I’ve tried other oil additives before, but none match the quality, reliability, and consistency of LIQUI MOLY. It’s perfect for professional use, and the 300 ml size is ideal for treating multiple engines without waste. For anyone running a tuning, repair, or automotive workshop, this additive is a must-have. It’s a small investment for real improvements in engine performance and longevity. Highly recommend!

Has definitely quietened my engine and made things a bit smoother. Cannot speak to fuel economy but the additive seems to be of high quality. Engine is quieter in cold start

As expected, the product is high quality. Liqui Moly consistently delivers great results. The pricing is very competitive, and the delivery arrived ahead of schedule

I have used this in a 2005 Mercedes C180K with 105K on the clock, the compressor was just a little rattly on start-up so I thought I would give it a try. The vehicle has been well serviced and looked after. There is no doubt that the compressor is now very quiet on start-up so the application has made a difference, as regarding normal running I cannot comment as the vehicle did not have any issues. My feeling is that there is a slight improvement in MPG but I do not have any empirical evidence to support that claim. Is it worth the outlay? I would say yes in my case but you always have to be aware of the placebo effect............

Do same journey 5 times a week in my bmw 118d , Same roads and after adding liquid moly oil additive to my engine oil I have gone from average 58/61mpg to 63/66mpg . Have ordered more for my partners 318d .

My car is 111k miles old and after adding it my camshaft went silent.

This is truly brilliant additive for almost all engine oil additives. It almost stops wear within the engine. I have used this molibdium sulfide in all my cars for the last 50 years & I run my vehicles hard & long. I do not wait for the engine to warm in any weather, I just go out get in, start & drive. Because Liqui Moly protects the engine bearings, sleeves & all moving parts, from the onset. Also you can buy a Gearbox, rear axle (final Drive) & some cars Turret Top oil additive too. But always check as some gearboxes require thicker oils . But if you can use Liqui Molly you be a fool not to. Old classics & vintage cars too. Please note, Any Engine Oil company will never agree to using an additive, or they be liable for selling an inferior oil.

Quite a sludge like product… used once but prefer STP

Aucun danger, maximum 100/💯 de produit associé a une huile 0-40 est une mixture parfaite pour une usure minimum. Produit top.

Das ultimative Mittel damit es im Getriebe rund läuft! Seit Jahren bei mir im Einsatz.Egal ob Auto,Roller oder Rasenmäher ( Benzin).Die Motoren laufen sofort ruhiger, gleichmäßig.Das kann ich wirklich nur empfehlen.Preis/ Leistung ist super gut !!

Der Dieselmotor läuft merkbar ruhiger, gerne kaufe ich bei Bedaf wieder.

Mejora el sonido y el rendimiento del motor y lo protege del desgaste
