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!

Pretty good - I'd seen some videos and decided to give it a go - added to diesel and instantly made the engine run more smoothly and quietly. Will need to give it some time to see if the fuel economy improves. 1 can did 2 cars (150ml each) or 5% of your engine oil capacity (i.e. if your capacity is 4L engine oil - 4000ml , 5% of that is 200ml, so slightly below 5% each)

Brilliant additive, always use on my home service, for the money it makes sense. I used Molislip years ago when I used to rebuild motorcross engines, so if you’ve ever had this product on your fingers you’ll understand the lubricating abilities it has

I’m old enough to remember Molly Slip oil addertive. I worked in BMS Motor Spares while I was doing my exams and remember being told how good Molly Slip was. My current car is a 2017 VW Golf 1600 Diesel turbo with 80000 miles on the clock. I thought I’d give this oil treatment a try. I’m amazed at it. I haven’t changed anything else on the car but it’s running cooler, quieter and smoother and my mpg have gone from 46 mpg to 52 mpg. Great stuff well recommended!

Funny colour but , done the job that it stated.

Good product seems to have made fuel efficiently better and has smoothed the engine out. Was smooth anyway but seems to improved more. Would use again every oil change, for the money it’s silky not too.

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

I've used moly slip since the mid 60s, when I used to race a 850cc mini, everyone in the club used it because oil wasn't as good as as it is today. Molly slip (liquid molly) prolongs engine life, improves economy and protects combustion engines, they run smoother it's great stuff. I've never blown an engine even under great stress, use it every oil and filter change, you'll notice the difference

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

Superbra!

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