SAE 15W-40 Magnum High TBN CI-4 Oil

Lucas Magnum SAE 15W-40 oil was designed to last up to twice as long as plain 15W-40 oils! It holds much more soot in suspension than conventional 15W-40 oils. You can expect extended drain intervals, longer engine life and no dry starts. It is also the perfect lubricant for hard working hydrostatic transmissions.

Key Benefits

  • Designed to last longer than plain 15W-40 oils
  • Longer engine life and no dry starts
  • Lubricates and protects
  • SAE 15W-40 Magnum (High TBN) is designed for use in pre 2007 trucks without diesel particulate filters.  Very effective in engines using high sulfur fuels

I would recommend Lucas products to anyone with a diesel…

I have been using Lucas products in my 2001 Ford diesel since new with much success, it has over 250000 miles and going strong. I would recommend Lucas products to anyone with a diesel.

Lucas is SERIOUS about what they sell.

After checking my Power Steering Fluid on my Kia Spectra, I noticed the level was low. Bought the Kia new and its now 4 years old. I decided to drain the rest of the power steering fluid and replace with Lucas Power Steering Fluid purchased at Auto Zone. What a noticeable difference in steering! Price was a few dollars higher and I would spend a few more knowing Lucas is SERIOUS about what they sell. 100% would recommend Lucas Power Steering Fluid.

Try out the Motorcycle Oil Stabilizer you’ll hear the difference…

My Harley always had the top end tick like most bikes do. So I decided to purchase the Lucas Motorcycle Oil Stabilizer. Wow I can't believe how much this has helped granted it's still makes noise but it dampens it down alot! I run Lucas Synthetic 20w/50 in my motor with Lucas Gear Oil in my trans. And Lucas primary oil. I don't care what anybody says Lucas makes some great oils! Try out the Motorcycle Oil Stabilizer you'll hear the difference it made a believer out of me and it will you too!

Now the engine is “humming” like it was brand new.

Complete Engine Treatment added to engine oil eliminated squeaking from engine during ignition and now engine is "humming" like it was brand new. 2003 LEXUS RX 300 108K.
