Liqui Moly Gear Oil (GL4) SAE 85W-90 | 1 L | Gear Oil | Hydraulic Oil | SKU: 20016

I recently used Liqui Moly Gear Oil for a rear differential fluid change, and I’m seriously impressed with the results. From the moment I opened the container, I could tell this was a high-quality product. It has that signature Liqui Moly consistency—clean, thick, and formulated to do the job right. After changing out the old fluid and replacing it with this, I immediately noticed a difference. The gears run quieter, and shifting feels smoother—especially under load or when the vehicle’s cold. I’ve driven about 1,000 miles since the change, and performance has remained consistent, even in varying temperatures. One thing I really appreciate is the built-in additive package. Liqui Moly’s reputation for advanced formulas holds true here—it protects against wear, resists foaming, and keeps the differential cool, even during long hauls or heavy towing. Pouring it was simple with the well-designed bottle and spout—no mess, no waste. And yes, it's a bit more expensive than generic gear oil, but the peace of mind and improved performance are absolutely worth it. If you’re serious about maintenance and want long-lasting protection for your transmission or differential, Liqui Moly Gear Oil is a no-brainer. It’s German-engineered excellence in a bottle

Excellent product and exactly what I needed to service the differentials on a golf cart. Liqui Moly quality, the only suggestion I would make is put it in a flex fill style bag like other brands (then I don’t need to pump it in the diff due to space constraints)

was delivered in a timely manner and worked as advertised. Good value for the price.

I just purchased a 2015 Chrysler Town and Country touring edition. It currently has 224, 000 miles. I bought this product and followed instructions. I ran this product on newer oil roughly 400 miles on it and ran it for 10 minutes in between 1500 rpm and 2,000 rpm. This van had a lifter knock. Not bad but noticeable. I drained the oil. It was kinda brown but still could tell it was newer oil. Mind you bottle states run for 10 minutes or longer. I only ran for 10 minutes because you do not want this cleaning your engine to quick. I then put new oil back in. I purchased Valvoline Restore and protect. The only oil that has lab data to prove it also cleans piston rings, time chain guides etc. I started up my van.....the knock was there for 3 minutes and disappeared and purs like a kitten. I will run for 300 miles and change the oil filter so it doesn't get clogged or over worked. I highly recommend this product if used correctly, do not over run the time of 10 minutes or the rpms. But the biggest factor is valentine restore and protect. I watch the engine oil geek on youtube. Please watch his videos. I will look in to the fuel additive this company makes to see if it has polyetheramine which is the strongest detergent to use in cleaning carbon build up.

Does exactly what it's supposed to do

Yeah good oil for Altis Sigma And KTM 890

I used this oil to service the differential in a VW 01M transmission that was in working order (despite being slightly low on fluid after 18 years/170k miles of service). This is not the synthetic GL4 I originally set out to use, but it seems to be doing just fine in the low load application of my car. I have not noticed any leaks after a few thousand miles, so all seems to be well. My application did not require the full 1L and the nozzle worked well enough to complete my service.

Used in my vintage British motorcycle, and it shifts very smoothly. If your application requires a GL4 gear lubricant I would recommend this product.

Perfect for my differential, made a noticeable audible difference as well as feeling smoother to drive
