LIQUI MOLY MoS2 Antifriction SAE 10W-40 | 1 L | Part -synthetic engine oil | SKU: 2042

Great oil my car burns a lot of oil even full synthetics. This oil still burns but the rate has noticeably reduced compared to the last stuff I used. A bit pricey but worth it

recently used the LIQUI MOLY MoS2 Antifriction SAE 10W-40 part-synthetic engine oil, and I am thoroughly impressed with its performance. This product performed exactly as advertised. The engine oil provided excellent cold-start behavior, making starting the engine in low temperatures much smoother. Additionally, it maintained stable viscosity and remained resistant to aging, which is crucial for long-term engine health. One of the standout features is that it has no harmful effects on catalytic converters, which is a significant advantage for maintaining overall vehicle performance. Overall, the LIQUI MOLY MoS2 Antifriction engine oil exceeded my expectations and delivered on all its promises. I highly recommend it for anyone looking for reliable and high-quality engine oil.

I have an 86 F-150 I lost all oil pressure on my way home from work one night. The lifters we’re tickin pretty bad for sure but I made it home and it sat for a while because I thought the motor was done for. Then I found out about this stuff. I decided ah what the hell what do I have to lose at this point and drained my old 30 weight oil and replaced it with this liquimoly mos2 and although I did get oil pressure back it took about 200 miles or so for the lifter tick to go away. I have videos of what the motor sounded like before and after using this oil but I can only upload one video unfortunately. It doesn’t really matter at this point for me because my motor ended up catching on fire due to the old rubber fuel hose rupturing and spraying gas all over the top of the engine. Was already driving home when it caught fire. I made it home thankfully and was able to put out the fire with an extinguisher before the fire spread any further. I just had to write a positive review about this oil tho I highly recommend.

This stuff looks like used motor oil but don’t worry that is the molybdenum disulfide (MoS₂) which is black. This stuff in a small engine makes it smooth as silk. I used it all season in my leaf vacuum small engine. I could hear the difference. It was quieter and smoother.

Brand name of this product is great for me and a good value for the money considering the MoS2 content for older engine oils not readily available in most US stores. The MoS2 content is extremely noticable on first pour, being near charcol in color. I trust this oil for better sealing and much longer durability, being greatly appreciated for being completely compatable for my flat tappet camshaft applications. I am of no concern, but less friction makes gas mileagean increase.

excellent quality, super delivery

Containers were not 5QT. like I had typed into search bar. They Are 1QT. Lots of Money for ONE QUART OF OIL

After viewing a Mercedessource video (trusted Mercedes repair advice Youtuber and blogger) on which oil he liked for higher mileage Mercedes he pointed this out Semi-synthetic 10w-40 out. Called it “muddy” oil. Said it possibly helped with small oil seal leaks and seemed to slow oil loss in higer miles Mercedes. Also made the engines run more quietly. So I have been using in my wife’s high mileage Mercedes (185,000miles W211 2004 E500 4matic) which we baby and I work on. A true very high compression super car, everything he said at Mercedessource has turned out to be accurate. No more leaks. Quiet lifters. Cooler running. Wow. I had been using Mobil 1 full synthetic 0W-40 European Car Formula exclusively but tried this for the seal protection. Works great and no, it is not Mercedes spec but I will see when the harsh Utah winter hits. May switch to the Liqui-Moly 5W-40 Leichtlauf full synthetic (which does meet Mercedes 722.9 oil spec) for winter (I change the oil every 6 months regardless). Thanks for reading.

best products for older high mileage German cars

I have a 383 stroker in my classic car. Could not find the blend I needed in my local store. Was surprised though by the color as it looks like used oil right out of the jug. But I guess that's due to the addictives.

I highly recommend this if you have an old vehicle and want to keep her going. I have an old VW Vanagon and wouldn’t use anything else. Coincidentally it’s made in Germany the ancestral home of VW’s 🙂

Works as expected!

Very fast delivery , changed the oil the next day, I can't believe how quite the engine runs now, just so smooth!
