Exol’s long-term reliability demonstrated in Mercedes-Benz testimonial

Our Optima C3 5W-30 engine oil has proven its performance in Mercedes-Benz vehicles over more than a decade of regular use.

Alec Nemeth, owner of an OM651-powered Mercedes-Benz C-Class (W204), and his wife’s 2008 SLK200 (R171), have relied on Exol’s fully synthetic, low SAPS Optima C3 LS range for both engine and transmission care.

These oils are specifically engineered to provide long-term protection, reduce friction, and support optimal performance even under the high-stress conditions of everyday driving.

Nemeth commented: “The benefits of Exol Lubricants became clear when I recently addressed a common 651 engine oil leak. While I replaced the oil cooler, filter housing and cam cover gasket, the timing chain had no slack at all, which was my biggest concern. My C-Class is now approaching 190,000 miles, so I really can’t complain.”

The Optima C3 LS range is formulated to cater to a wide variety of engines, including those of Mercedes-Benz, offering peace of mind for vehicle owners who demand long-term reliability and consistent performance.

Nemeth added: “Exol has provided expert guidance on the right engine and transmission oils, competitive pricing and fast delivery. It’s reassuring to know that the vehicles I depend on are running on products I trust!”

We are continually striving to deliver high-performance solutions, supporting daily drivers, commercial vehicle drivers, rail, off-highway, motorsport racers, anyone who requires dependable, long-lasting lubrication. And we have been doing so for over 40 years. It’s fantastic to see the real-world results of our products in providing the ultimate in engine protection.
