What is RUBY RED?

RUBY RED is a blend of petroleum and synthetic base oil, which incorporates the purest and finest severely hydro-cracked and hydro-finished base stocks available. This unique combination of base stocks means RUBY RED provides improved oil flow for superior cold cranking protection. In addition, when high engine operating temperatures are encountered, which is common with low emission engines, this unique synthetic blend ensures a superior oil film of protection for vital moving engine parts.


RUBY RED uses superior additives in higher concentration than conventional oils, diesel engine designs expose engine oils to elevated amounts of contamination. Special compounds are needed to neutralize acids, plus suspend and disperse large amounts of soot. RUBY RED keeps soot and particulate matter suspended (in the form of smaller particles) to prevent wear to liners, rings and the valve train.

Some diesel engine designs place higher temperatures on the engine oil, which coupled with exhaust gases, could act as a catalyst for oxidation of the oil. An improperly functioning exhaust gas recirculation system can cause much more rapid deterioration of an engine oil. RUBY RED uses a beefed up oxidation inhibitor to counteract oxidation or sludging. Routine oil analysis & RUBY RED helps to allow longer drain intervals.


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 is made with a 15 Plus total base number (TBN). This is extremely important since air is 60% nitrogen and some engines take in 16,000 gallons of air per minute. Acidic compounds can form because of all the Nitrogen; therefore, the ability of RUBY RED to control corrosion is a top priority. The extra protection from the high Total Base Number in RUBY RED provides exceptional protection to reduce ring and liner wear.


A great way to reduce cost is to reduce oil consumption and RUBY RED does this extremely well. While results will vary, typically by using RUBY RED, oil make up between drain intervals is greatly reduced, while drain intervals are dramatically extended. This combination, in actual field usage, shows oil consumption cut by as much as 60%. Naturally, individual results will vary with engine and operating conditions.


It has been proven that a cleaner operating engine is a more fuel efficient engine. Reductions in varnish, gum and sludge in engines help an engine operate at peak efficiency. RUBY RED contains superior detergent/dispersant additives to provide high temperature cleanliness, control corrosive wear, help suspend soot and help to neutralize acids. The superior detergent/dispersant additive package of RUBY RED is a key reason extended drain intervals are possible along with improved fuel economy
