Give the green light to the green oil.
Size: 5 Liter, Style: 1 Pack, Configuration: 0W-20
Great oil. I've used Liqui-Molly in all my vehicles and it always performs. Theres very little burn off between changes and I noticed cleaner, quieter engine. I've used this in many different car brands, it never disappoints.

Car Runs Smooth, Less Friction, and Improved Performance at Start Up and Underload.
Size: 5 Liter, Style: 1 Pack, Configuration: 0W-20
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.

Liquid Gold for Your Engine! 🛢️💥
Size: 1 Liter, Style: 1 Pack, Configuration: 5W-40
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. 😉

Near OEM quality at 1/4 cost
Near OEM performance at 25% of the cost! Bosch Quality replaced NGKs/Toyota OEMs. Great value and now the engine is running smoothly! I have seen a slight improvement in my mpg @1mpg overall in mixed driving conditions.

Very Expensive
Had one cylinder misfiring so replaced coil and spark plug. Runs fine now, but old plug looked shot after only 5 months so I think the coil was the problem. Really good plug so far but very expensive.
