15W-40 Magnum High TBN CI-4 Oil

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.

  • 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

The improvement was immediate...

I bought a 2017 HD Freewheeler trike with the new 107 cu. in. M8 motor in June, 2017. After the break-in 1,000 mile service, I rode it home & switched over to Lucas 20W-50 Synthetic High Performance motorcycle oil in the motor, transmission & primary. The improvement was immediate, with the motor temps dropping 15-20 degrees & the shifting clunk/noise & finding neutral problems improved dramatically. I am a user for life & at my 10,000 mile service, will switch over to the dedicated Lucas differential & transmission fluids. -Michael O.
