Trusted reliable brand
Size: 5 Liter, Style: 1 Pack, Configuration: 5W-30
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.

The best thing you can use in a Tahoe! Period!
Size: 5 Liter, Style: 1 Pack, Configuration: 5W-30
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.

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
