Liqui Moly 8973 Top Tec 4200 5W-30 5L

I’ve been using Liqui Moly 8973 Top Tec 4200 in my car tuning and workshop business for quite some time now, and it has consistently impressed me. Whether it’s high-performance tuning projects or standard service work, this oil delivers exceptional protection and performance every time. The engine runs smoother, quieter, and more efficiently, even under heavy loads. I’ve tested it across multiple brands and engine types, and it always meets or exceeds manufacturer specifications. It’s perfect for modern vehicles that demand high-quality synthetic oils, and I’ve noticed better fuel economy and improved engine response since I started using it consistently. What I love most is the confidence it gives me when working on customers’ cars — I know I’m using a professional-grade product that protects engines while keeping performance at its peak. For any tuning or automotive workshop, Liqui Moly Top Tec 4200 is absolutely essential. Highly recommend for anyone serious about engine health and longevity.

After looking at reviews online I used this oil to service my BMW 320i b48. Very good oil my engine runs much better. I would use again.

Great value for money great oil can feel the difference

This brand is the exclusive oil I use for both my Seat and my Audi. You don't just put it in and forget about it—you can genuinely feel the difference in how the engine runs after every oil change. For anyone looking for maximum engine longevity, I also highly recommend using the Liqui Moly oil additive for that extra layer of protection.
