great oil for your engine; feels very smooth in general
The Best motor oil I have used.
I recently began using this brand and 5W-30 instead of 0W-20 in my Chevy Silverado; noted smoother operation and no lifter ticking sounds. There feels like there is better engine protection which should add to long-term durability. This is compatible with trucks as well as cars. Probably adds a few better numbers on gas mileage too.

The Best!!
As a proud owner of a BMW 328i Wagon, I'm always on the lookout for the best products to keep my car running smoothly and efficiently. After doing some research, I decided to give Liqui Moly Special Tec B FE SAE 5W-30 Motor Oil a try, and I'm extremely impressed with the results. This motor oil is specifically formulated with synthesis technology to meet the high-performance demands of modern engines, making it an excellent choice for my BMW. The 5W-30 viscosity rating ensures optimal lubrication and protection, even in extreme driving conditions and temperature fluctuations. I've noticed a significant improvement in engine performance since switching to this motor oil—the engine runs quieter, smoother, and more efficiently, with better fuel economy and reduced emissions. Plus, I appreciate the long-lasting protection it provides, helping to extend the life of my engine and reduce the need for frequent oil changes. The 5-liter size is convenient and cost-effective, providing plenty of oil for multiple oil changes. Overall, I highly recommend Liqui Moly Special Tec B FE SAE 5W-30 Motor Oil to BMW owners looking for a premium motor oil that delivers exceptional performance and protection.
