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! ### ⭐⭐⭐⭐⭐ Instant improvement in engine running *by on Reviewed in the United Kingdom 5 May 2026* 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) ### ⭐⭐⭐⭐⭐ Great in a Diesel and more mpg *by on Reviewed in the United Kingdom 15 June 2026* 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! ## Frequently Bought Together - LIQUI MOLY Oil Additive | 300 ml | Oil additive | SKU: 2591 - LIQUI MOLY Pro-Line Engine Flush | 500 ml | Oil additive | SKU: 2427 - Liqui Moly 2770 - Engine Oil Additive --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/48193115-oil-additive-300-ml-oil-additive-sku-2591](https://www.desertcart.tn/products/48193115-oil-additive-300-ml-oil-additive-sku-2591) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-20*
