Smooth, Quiet, and Reliable Protection
Size: 5 Liter, Style: 1 Pack, Configuration: 0W-20
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.

Great Stuff!
Size: 5 Liter, Style: 1 Pack, Configuration: 5W-30
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!

Super nice and smooth, so much power! Car feels nimbler. Worth the price
Size: 5 Liter, Style: 1 Pack, Configuration: 5W-50
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

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.
