- Molygen New Generation SAE 0W-20 | 5 Liter | Fully synthetic engine oil | SKU: 20438

I kept hearing things about this oil from a few friends that work on cars and from my "go-to" mechanic. I was previously using Mobile 1 0w-20 on my 2024 4Runner and my wife's 2025 Outback Onyx, and this time around I decided to try it on both cars as they needed an oil change. So far I am happy with the change for both cars. This is good oil quality, smooth engine running, and noticeable oil lubrication at cold start. I am getting better MPGs mileage on both cars. Also noticeable engine is running with smoother. I had to lower my car window to check that my 4runner was on as it was quiet. I will update my review after a second oil change with this oil on both cars.

I recently switched over to this oil and it’s honestly one of the best upgrades I’ve made for my 2018 Mazda 3 Hatchback 2.5L. The 5 liter jug is the perfect amount for a full change, and I really like knowing it’s a high-quality fully synthetic formula that gives my engine the protection it deserves. The first thing I noticed was how much smoother cold starts became—no more of that rough, clunky sound in the mornings. The engine feels quieter overall and runs more efficiently, like it’s not straining as much. I’ve also seen fewer deposits and buildup, which gives me peace of mind about long-term wear. Another thing I appreciate is that it’s designed with modern engines in mind—safe for turbocharged setups and catalytic converters. It also blends easily with other oils, which makes topping off simple if I ever need to. Highlights for me: Excellent cold-start protection, even on chilly mornings. Noticeable improvement in smoothness and reduced engine noise. Works well with today’s engines, including turbos. Easy to mix when topping off. Overall, this oil gives me confidence that my engine is well-protected and performing at its best. Definitely feels like a premium choice that’s worth it.

I watched several videos on synthetic oils. Moly, Amsoil and Pennzoil Ultra Platinum kept engines clean with little wear. Amsoil was the winner of engine wear, drain interval and removal of existing sludge and varnish. It is also most expensive. Moly doesn't like to mix with other oils. It purports to increase fuel economy. If you want to use it you should do a second oil change the following day. Moly is a very good product as is Pennzoil. Neither Moly or Pennzoil encourage extended drain intervals. Probably a max of 7,500 miles or one year which ever comes first. I decided to go with Amsoil 5w30 for least engine wear including the timing chain and cleaning existing sludge and varnish. I am currently running Valvoline Restore and Protect for up to 5,000 miles to remove a substantial amount of sludge and varnish before making the switch.

Best quality, new item, best service and value ,looks fabulous.

Hands down the best oil on the market. Car drives much smoother after 2 oil changes. Excellent product.

If you’re new to LiquiMoly and reading these reviews, I can assure you that these are the best motor oils in the world. I’ve been using various formulas and weights in all of my cars over many years, and have never experienced any major engine failures. I use LiquiMoly motor oil in combination with their Ceratec product. This particular oil, the MolyGen range, already has a friction additive in it so you don’t need to use the Ceratec. Obviously it’s an excellent oil and has kept my heavily used truck running smoothly and flawlessly. One odd characteristic of the MolyGen oils is the strange green color. You feel like you’re dumping antifreeze/coolant into your engine. I had to explain this to my dealership when I brought my truck in for service when they saw the color of the oil. Anyway, this is an excellent oil. Don’t waste your money on Mobil 1 or Pennzoil or any of that other mass produced stuff when you can buy this for a similar price.

Best automotive oil on the market. Only brand I will use in my cars. Used specifically for a 2015 Lexus RC350.

I will give it a 4 star for now. Only 500 miles into use. Did quiet valve chatter some. Time will tell.

Easy winter starts with 0w20 if your car can use it. High quality synthetic that costs more than most others but works well in my car. Crazy good mileage in my ‘22 Lexus with 3.5l V6 even at steady 130km/hr. Granted I’m a believer, which is almost a religious thing when it comes to motor oil!

I Added this oil with MoS2 engine wear protector . Vehicle is good no knocking from engine due to slow speed. Mileage increased well. Liqui moly + MoS2 + 91 octane fuel stands best for vehicle life. CVT is a crappy gear box . But it works great in my car . I would say best oil ever .

It’s liqui moly and it’s 0w20 but Not the same product as shown above. It’s Spec tech AA

Best engine oil

Good German Oil for my CRV quality product and nice performance
