## 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: Instant improvement in engine running - 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)

## 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.
Rick,
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!

### ⭐⭐⭐⭐⭐ Good product
*by D***R on 21 April 2026*

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.
