Our Testing Experience

First Impressions

When I first got the LIQUI MOLY Leichtlauf High Tech 5W-40 oil, I was impressed by the large 5-liter can. The container felt sturdy and easy to handle, which made pouring the oil into my engine much less messy than I expected. The size of the can, about 3.5 by 10 by 13 inches, fits nicely in my garage shelf without taking up too much space. I was curious about how this synthetic oil would perform since I’ve mostly used regular oils before.

Daily Use

After changing the oil, I immediately noticed the engine running smoother. Over the next few weeks of daily driving, the car felt more responsive and quieter, especially when starting up on cold mornings. The 5W-40 viscosity seemed perfect for my needs, giving good protection without making the engine feel sluggish. I also liked that the oil seemed to keep the engine cleaner, as the performance didn’t drop even on longer trips.

Key Features in Action

The high-tech synthetic formula really stood out during my testing. It helped the engine parts move easily, reducing friction and wear. I could tell the oil protected my engine better than the conventional oils I’ve used before. The “Leichtlauf” (which means easy running) technology lived up to its name by improving fuel efficiency a bit and making the engine run cooler on hot days. This feature gave me peace of mind knowing the oil was working hard to keep my engine healthy.

Long-Term Performance

After several months and over 5,000 kilometers, the LIQUI MOLY oil still performed great. The engine showed no signs of sludge build-up or rough idling. I appreciated that the oil maintained its quality for a long time, meaning I didn’t have to worry about frequent oil changes. Overall, this motor oil proved to be a reliable and high-quality choice that I would recommend to anyone looking for a durable synthetic oil.
