20230 Molygen New Generation 5W-40 Motor Oil, 1 Liter

I recently used LIQUI MOLY Molygen New Generation 5W-30 for an oil change and overall I’m very impressed with the quality. The oil feels like a premium product and the difference in engine smoothness was noticeable almost immediately after the change. The engine runs quieter and smoother, especially during cold starts. This oil uses advanced additive technology designed to reduce friction and protect internal engine components, which helps improve efficiency and extend engine life. It also helps prevent deposits and keeps the engine cleaner over time. () Another thing I like is that it maintains stable viscosity even under high temperatures and heavy driving conditions. It provides excellent lubrication and wear protection while also helping improve fuel efficiency. The oil is also compatible with modern engines, including turbocharged applications, this is a high-quality synthetic motor oil that provides excellent protection and performance. If you’re looking for a reliable oil that keeps the engine running smoothly and helps reduce wear, this is definitely a great option and worth the price.

This is like liquid gold for your vehicle,it's molecular make up,is far superior to any oil out there,as it gets hot,it's molecules bind to every component inside your engine and attaches itself to the metal and fills in the stress points,all points really,it basically soaks into the metals,and is by far the most long lasting and does not break down like other oils,I get 10k off one oil change and I have 273,000 miles on my 03 Tahoe and this stuff is incredible I don't have any ticks,clicks,knocks, Nothing,not on fire up,cold start,my truck runs about five degrees cooler,I get a couple more miles to the gallon and my motor purrs like new,I could probably go 12-15k between oil changes,but I change it with the filter at 10K a new AC Delco pf46e and a 5-1/4 qt jug of liquid moly 5-30 full synthetic a new crush washer and I'm good for 10,000 miles Easily.

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.

Purchased for my husbands F-150 Truck , his engine was making a weird noise and he thought he was going to have to get a new engine but a friend recommended to change his oil and use this one. Boom, it worked! Couldn't believe it cleaned the engine out and the noise went away. Engine seems to be working fine now. Will definitely use again!

I normally don't buy such expensive engine oils (normally buy cheap diesel truck oils add in MoS2). However, this one was well worth the purchase. Engine feels substantially smoother and quieter. After running for a while, the car feels a lot nimbler. More power, and as if it simply wants to keep moving rather than whining. It glides like a magic carpet

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.

Happy with this oil. Using in 2.0 liter GM LTG turbo engine, audible lifter ticking sound is now gone. The car drives great. I can definitely feel less noise with this oil vs stock Dexos oil or equivalent Mobil full synthetic. Recommended!

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.

One of the best engine oil ever used

My 2004 Audi A4 2.0i used to burn almost 2 litres of oil per 1000km. I was looking for a way to fix the problem. Friend of mine recommended to flush the engine using liqui moly engine flush and to use this oil. The combination gave a new life to my car. It now burns only 0.25l of oil per 1500km. The oil stays clear even after 3000km and that means the oil don't lose its properties after It's heated up in your engine. It is a bit expensive, but for the money you get an oil that is a real fully-synthetic oil. Another plus point is that the engine runs as smooth as silk, I couldn't tell if the engine was on or off. Totally recommend it if your VW/Audi(or any other car) burns too much oil.

Delos mejores aceites del mercado, envío correcto, todo bien.

Todo ok, es la primera vez que lo pongo Citroen Xsara Picasso 1.6 HDI , veremos resultado motor con 230000KM

I run this Liqui Moly Molygen New Generation 5W-40 in my BMW E92 N55 running MHD Stage 2+ with XHP Stage 3 transmission tune, and I won’t use anything else. On a tuned turbo car, oil quality really matters — especially with higher boost and harder driving. Since switching to this oil, cold starts are smoother, idle is quieter, and the engine feels more refined overall. Even when pushing it, temps stay stable and the engine doesn’t sound stressed. After full intervals, the oil still holds up great with no excessive consumption. No burning smell, no weird ticking, just solid protection. The Molygen additive technology gives extra confidence knowing the internals are protected under higher load. If you’re running a tuned N55 (or any performance setup), this oil is absolutely worth it. Premium protection for a boosted engine. I’ll keep buying this every single oil change. 💚🔥
