SUPREME ULTRA HD
INDUSTRY HIGH TBN
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 . . . Introducing SUPREME ULTRA HD. SUPREME ULTRA HD has an industry high TBN of 14! This new, ground-breaking technology formulated into SUPREME ULTRA HD provides you with one engine oil to protect on-highway low emission diesel engines with after treatment devices, pre-2007 diesel engines, as well as Tier 4 off-road diesel engines. SUPREME ULTRA HD 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.
ADVANCED DETERGENTS
SUPREME ULTRA HD offers the most advanced detergent package among CJ-4 oils in the industry today. SUPREME ULTRA HD’s ability to eliminate the build-up of existing varnish, gum or sludge at changeover is critical to extending engine life.
DISPERSES SOOT
SUPREME ULTRA HD 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.
OXIDATION PROTECTION
The operating conditions of your engine are more extreme than they were in the past, with much higher temperatures placing demands on the oil. As temperatures rise, the process of oxidation can begin to cause problems for you, unless you are using SUPREME ULTRA HD. Less oxidation means less deposits in your engine, longer drain intervals and more time for your equipment to make money.
