20226 Molygen New Generation 5W-30 Synthetic Motor Oil - 1 Liter

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 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 didn’t think I’d get excited about motor oil, but here we are—Liqui Moly Molygen 5W-40 has officially made me feel like a car enthusiast. If you're serious about keeping your engine purring like a kitten, this stuff is like giving it a spa day with an energy drink chaser. First off, this isn’t just any old motor oil—it’s high-tech motor oil. We’re talking German engineering at its finest. The neon green color? Oh yeah, it looks as cool as it sounds, and trust me, when you see that green oil running through your engine, you know you're in for some serious performance. 🟢💯 Why do I love it? Engine protection: This oil is like a security blanket for your engine. It reduces friction like a champ, so parts glide smoothly, which means less wear and tear. Translation: your engine will thank you with better performance and a longer life. Fuel efficiency: You’re not just getting a smoother ride; you’re also saving some bucks at the pump. The way this oil cuts down on friction helps with fuel economy. It’s like the gift that keeps on giving. Cold start-ups? No problem. Whether you’re dealing with a chilly morning or scorching summer, this oil handles temperature extremes like a boss. It maintains its viscosity so your engine stays protected regardless of the weather. And did I mention the Molygen technology? It’s not just a fancy name—this oil has additives that coat your engine in a protective film, keeping it running smooth and reducing the risk of damage, even during high-stress drives. Final thought: If you're looking for an oil that’s as serious about your car’s performance as you are, the Liqui Moly Molygen 5W-40 is it. Your engine will run smoother, quieter, and stronger, and you’ll feel like you’ve just upgraded your car’s lifeblood. 🚗💨 Plus, that neon green color? Total conversation starter at the garage. 😉

It's been 5 days since I switched my oil from Royal Purple to Liqui Moly, and I feel like I can now give an honest review. Many people I talked to didn't like that I'm buying fancy, overpriced oil, suggesting I change it more frequently to save money. Well, after just 5 days of daily driving my 2014 Chevy Tahoe, I've noticed some differences. Please note, I'm not a mechanic; I'm just sharing my opinion. While I have some experience turning a wrench, my car knowledge is slightly above average. Over the past 5 days, here are some things I've noticed: I had a very quiet lifter tick before this oil change, which is now 100% gone. The only thing you can hear is the pure V8 rumble. The oil pressure went up slightly (see pics) when cold, and idling sits pretty high, almost at 40 PSI. Once warmed up, it's more around 28-30 PSI. Before the switch, it sat at around 20 (warm) and 30 (cold). Every time I've taken it on the highway, I stomp on the gas to get up to speed, and the needle is almost touching 60 PSI. So, it seems the oil is flowing better, and the internals are getting proper lubrication. MPG hasn't improved; it won't go lower than 15 mpg, and the highest I've gotten is 15.5 mpg (I have a heavy foot, and I have all terrain tires on my Tahoe). Also, I have the plug-in AFM disabler, so it's in V8 mode all the time. It's not much more expensive than what I was paying before. The total price for oil and filter comes out to $90.36 after tax, while I was paying about $75 for the Royal Purple high mileage oil I used before. So far, the pros are quiet lifters and improved oil flow. Cons are it's more expensive and harder to get (only at Amazon/NAPA). You can obviously use what you want, but for those interested in trying it out, here you go! In my opinion it’s just cheap insurance for your motor. Sure you can buy cheap oil and change it more frequently or you can buy Liqui Moly and maximize the life of your motor.

Installed on my 2021 Tundra 5.7. It only has 20k miles however since changing the engine runs a lot quieter and smoother. Not sure about the gas mileage lol. A-lot quieter on startups.

Strange color, great results!

I’ve been using the liquid moly products now for 3 to 4 years in Audi vehicles however I saw that this was also available in a 5W/20 blend for ram pickup trucks. I have a 2018 ram 1500 (5.7L gas) and 2+ years back it developed the famous hemi tick when I was using Mobil-1 extended protection full synthetic oil that I changed every 5,000 miles but it just didn’t seem suited to the ram truck and I wanted something better so I switched to Royal purple 5w/20 Full synthetic and this seemed OK but the lifter tick would come and go (and sometimes it came badly) so when I found that you could get the liquid Molly for the ram trucks, I switched to this about 9 months ago and it has been engine honey and very quickly the lifter tick went away and 20,000+ miles later it has still not come back. Couple of quick things 1. I did run the liquid Molly engine flush, but from memory, I ran this when still using the royal purple and the tick would come and go. 2. Remember, Ram Trucks are also notorious for breaking manifold bolts and developing a nasty manifold exhaust tick as well, so if you have the same problem, make sure you know which engine tick noise you have! I also had the manifold tick that initially came from 3x broken manifold bolts in my factory manifold, i’ve been changed to Shorty BBK headers but these only last about 15-20,000 miles before they start breaking welds or bolts start coming looks, so I’ve now gone back to a high quality aftermarket manifold that has so far been excellent as I use my truck pretty hard, often pulling a 10K rated dual axle Equipnent trailer with heavy loads and I barely since I’ve changed over to the Liqui-Moly I barely need to even change this oil before 10,000 miles and it still changes pretty clean (my truck now has close to 150,000). As another note you can solve the ram lifter tick by changing to a high-volume oil pump, however the Liqui-Moly engine oil is Liqui-Magic (at least for my Ram Truck) and wile it’s pricey I think it’s worth every dollar more that you pay for it, and I will never go back to a different oil.
