Why RUBY RED II?
The ground-breaking technology formulated into RUBY RED II provides you with one engine oil to protect on-highway low emission diesel engines with after treatment devices, pre and post-2007 diesel engines, as well as Tier 4 off-road diesel engines. RUBY RED II is a new generation engine oil that provides emission system durability, prevents catalyst poisoning and particulate filter blocking, while at the same time controls soot thickening, oil consumption and wear prevalent in EGR engines.
87 years of world-class manufacturing experience has enabled Royal Oil Co. to develop the most robust Total Base Number in the industry, miles ahead of other CJ-4 oils on the market.
RUBY RED provides increased soot control. Royal Oil Co.’s RUBY RED contains top of the line dispersants to control soot thickening, sludge, and varnish as well as keep other deposit precursors suspended in the oil so that they can be filtered out.
RUBY RED II is formulated with powerful dispersant chemistry to keep soot dispersed into finer particles, which results in reduced oil thickening and improved protection against abrasive wear.
RUBY RED II offers the most advanced detergent package among CJ-4 oils in the industry today. RUBY RED II’S ability to eliminate the build-up of existing varnish, gum or sludge at changeover is critical to extending engine life.
