## Description

Oil additive

Review: “Essential for My Tuning Business – Smooth, Reliable, and Professional!” - 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!
Review: LIQUI MOLLY, THE BEST ENGINE OIL ADDITIVE. - 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.

## Questions & Answers

**Q: Hi, It seems like that oil additive goes into engine oil? true?**
A: Hi, Yes, make sure the can/bottle has been warmed up in this cold weather, and give it a good shaking for a couple of minutes to thoroughly mix it, pour most of it in then stand the container on end in the cam cover for a few minutes to get it all out of the container.

Gainsborough.

**Q: some seller says that is not suitable for engine with wet clutch but only vehicle with separate gearbox; I have Honda SH300 can i use it?**
A: I’ve heard not to use with a wet clutch as well! If you’re unsure the answer should always be No!

### ⭐⭐⭐⭐⭐ Smooth As Silk
*by U***P on 30 July 2024*

My 85000mile Astra CUTIE 1.6 was in need of some tender Loving Care so bought this amazing product. In years gone by I used a similar treatment called Molyslip back in the 60s&70s. This modern treatment is exactly the same under a different brand name. Make sure you SHAKE THE CAN WELL for at least five minutes. I carried it round in my pocket for a morning. This allows The molydisulphide compounds to agitate adequately and mix with the additive prior to adding to your engine. Took the car for 10mile run to get a nice hot engine prior to adding the treatment then ran the car fast for further 10miles to ensure completion mixing of contents. Within 15min of adding the engine sound changed and knock disappeared. Rested the car overnight after returning from run. Start up the following morning was as smooth as silk. No rattling lovely even tick over. Ah Bliss. Wouldn't hesitate to recommend this product. The Astra performance was transformed. Fabulous acceleration through the auto box. Overall a very happy car.😁😁
