The Ultra1Plus™ 10W-40 Motor Oil collection delivers reliable protection, strong performance, and durability for gasoline, diesel, and powersport engines. Designed to perform under high temperatures and heavy loads, this oil ensures your engine stays clean and well-lubricated, whether you drive a car, motorcycle, or marine vehicle.
10W-40 oil is ideal for engines that operate under higher temperatures or heavier loads. The “10W” indicates that it flows well during cold starts, while the “40” shows it maintains viscosity at higher operating temperatures. This makes it a great choice for older engines, motorcycles, and high-performance vehicles that require thicker protection.
10W-40 oil is often recommended for older cars, light trucks, and motorcycles that experience higher wear or oil consumption. It’s especially suitable for vehicles that spend time in warmer climates or under more demanding driving conditions, such as towing or off-road use.
Full synthetic 10W-40 motor oil typically lasts between 10,000 km and 15,000 km, depending on your driving conditions and engine type. Always check your owner’s manual and refer to our When to Change Your Motor Oil blog to determine the right interval for your vehicle.
10W-40 is one of the most trusted choices for older engines because of its thicker viscosity and strong film protection, which helps reduce wear, oil leaks, and consumption. Learn more about how oil type affects aging engines in our Motor Oil Types guide.
For vehicles with more than 75,000 miles (120,000 km), 10W-40 high mileage oils provide enhanced additives that condition seals and reduce oil burn-off. Visit our high-mileage motor oil products to find the right formula for your engine.
While 10W-40 can handle moderate cold, it’s not ideal for extreme winter climates. Oils like 5W-30 Motor Oil or 0W-30 Motor Oil flow better in sub-zero temperatures, protecting your engine during cold starts.
For drivers needing stronger protection under heavy use, the 10W-40 Synthetic Blend Motor Oil is the perfect balance of performance and affordability. Choose from Full Synthetic, Synthetic Blend, or Conventional options depending on your vehicle type, climate, and performance needs.
