SAE 15W-40 Magnum High TBN CI-4 Diesel Motor Oil – Gallon

Description

When your diesel engine’s putting in long days pulling implements or running a PTO, regular motor oil just isn’t going to cut it. Diesel engines run hotter, work harder, and deal with more combustion byproducts than gas engines—that’s where this high TBN formula really shines. The extra acid-neutralizing power keeps your oil cleaner longer and protects against the corrosive effects that can eat away at engine internals over time.

What You’re Getting

• High TBN (Total Base Number) formula that neutralizes acids from diesel combustion better than standard oils
• 15W-40 viscosity that flows well on cold mornings but maintains protection under heavy loads
• CI-4 specification meets the demanding requirements of modern diesel engines with emission controls
• Extended drain intervals so you spend more time working and less time changing oil
• Superior wear protection for engines that see constant high-load operation

Built for Real Farm Work

This oil is formulated specifically for the diesel engines that power your operation—whether it’s a utility tractor running a bush hog, a row-crop machine pulling a 12-row planter, or a combine harvesting grain. Diesel engines generate more soot and acid than gas engines, especially when they’re working hard, and this high TBN formula is designed to handle those challenges.

Made to Last

Lucas builds this oil with quality base stocks and a robust additive package that maintains its protective properties even under severe service conditions. The high TBN means it can neutralize more acid throughout its service life, keeping your engine cleaner and reducing wear on critical components like rings, cylinders, and bearings.

Good to Know

The CI-4 specification ensures compatibility with modern diesel engines, including those with exhaust gas recirculation (EGR) systems. Always check your owner’s manual for the recommended oil specification and change intervals—while this oil can often extend drain intervals, severe dust conditions or high-hour operation may require more frequent changes.
