Liqui Moly (2043-4PK) MoS2 Anti-Friction 10W-40 Motor Oil - 1 Liter, (Pack of 4)

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.

The media could not be loaded. 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.

You need this product if you drive a high-mileage car. I own a 2002 Saab approaching 180K miles on the speedometer. I was leaking small amounts of oil into the engine. My Saab specialist suggested I use Liqui Moly as cars with high mileage need extra engine protection. This has been a wonderful discovery that has worked perfectly over the last 10-15K miles. No more oil leakage (if there is any, it is imperceptible). I change my oil every 3500 miles - and will only use Liqui Moly for my high mileage cars. Give your car the TLC it deserves.

I am so glad I was able to find LiquiMoly 10w-40. I usually buy LiquiMoly products from Napa but they didn’t have that specific oil. Put into my ‘85 Dodge D150 with the bulletproof 318 in it. Already swapped oil and can tell an immediate difference. Smoother, quieter and protecting it for me.

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.

Outstanding protected for vintage vehicles! Peace of mind for my investment that protects it on the road and on long term storage cold starts.

Ran this in my Mk2 golf for the first time and immediately noticed it running for the better. It’s been recently rebuilt and totally redone but this oil really is formulated well for this motor. Motor runs smoother and cleaner with less pops and cracks.

Great like every Moly product I've tried.This oil is a black/gray when new (right out of the bottle) and that how it should be.Good for up to 5,000 miles.I would change oil and filter again at that point.Boost in mileage and protects engines well.
