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.

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.

If you’re new to LiquiMoly and reading these reviews, I can assure you that these are the best motor oils in the world. I’ve been using various formulas and weights in all of my cars over many years, and have never experienced any major engine failures. I use LiquiMoly motor oil in combination with their Ceratec product. This particular oil, the MolyGen range, already has a friction additive in it so you don’t need to use the Ceratec. Obviously it’s an excellent oil and has kept my heavily used truck running smoothly and flawlessly. One odd characteristic of the MolyGen oils is the strange green color. You feel like you’re dumping antifreeze/coolant into your engine. I had to explain this to my dealership when I brought my truck in for service when they saw the color of the oil. Anyway, this is an excellent oil. Don’t waste your money on Mobil 1 or Pennzoil or any of that other mass produced stuff when you can buy this for a similar price.

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.
