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

HEAR IT FROM OUR CUSTOMERS

I am amazed at what it has done to my engine noise.

I own a 2008 Ford F`50 with a 5.4 engine and 137,000 miles. Over the past year my engine developed the Ford death rattle. It's known as cam phaser problems. This was when pulling a trailer at low idle. I decided to try out Lucas High Mileage Oil Stabilizer additive.T his was 12,000 miles ago, and I am amazed at what it has done to my engine noise. It's been gone since a week after I started using it. I told my son in law about it, as his Honda engine is using oil and fouling plugs. He is amazed at how it has helped his engine trouble and he has not fouled a plug since he started adding it.
I also have added it to my old Briggs and Stratton 5 hp engine. It smokes really bad, since adding it has cut it down 80 percent. It has made believers out of us. Thanks

I’ve been using Lucas Products for my vehicles for many, many years now with complete satisfaction.

I've been using Lucas Products for my vehicles for many, many years now with complete satisfaction. I came upon their gun oil many years back while at my local auto parts place while still living in California. Been using it ever since while all the other products I have collect dust.

I love LUCAS OIL

I have used nothing but Lucas Oil since I was younger. I've always seen improvements in every vehicle I've drove or recommended to use. The boost of mpg's is awesome. I know I'm burning cleaner. And OIL. Whoa don't get me started. Every oil change I supplement a quart. Dry starts gone. Ticking, noise, rattle, tapping........ gives in to the products. I love LUCAS OIL. I will always use it, my kids, family, and friends will too. Especially since they have me do their oil changes.

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.
