Bio-SynXtra Heavy Duty Motor Oil (Diesel)

Bio-Synxtra HD motor oil

These products are specially formulated to meet the requirements for EPA 2007 compliant diesel engines equipped with after treatment devices such as diesel oxidation catalysts and particulate filters that require low ash. This patented formulation contains the most advanced chemical technology available for high performance turbocharged and supercharged diesel and gasoline engines that require API Service SJ, SL, SM, SN/CF, CF-4, CG-4, CH-4, CI-4, CI-4 Plus, CJ-4, CK-4, and ACEA E2-96, E5-02, ACEA E7-02. In addition, this product provides excellent performance for small cubic inch turbocharged and supercharged diesel and gas engines in passenger cars, sport utility vehicles, light duty trucks, and motor sport vehicles that recommend a SAE 5W40, 10W40, or 15W40.

Renewable Lubricants, Inc. formulates this lubricant to exceed most API requirements. RLI’s patented chemistry is blended into the highest quality biobased and synthetic base stocks and provides extended engine life relative to other conventional oils without this proven chemistry. This premium quality additive technology has documented records of excellent field performance in terms of:

  • Superior wear and corrosion protection in both conventional valve train and overhead cams
  • Superior viscosity stability and low volatility reduces emissions
  • High temperature thermal stability and provides unsurpassed soot control
  • Superb protection from low temperature sludge and varnish formation
  • Enhanced shear and oxidation stability
  • Power-shift transmission performance for Cat TO-2, Allison C-3/C-4


Stabilized HOBS produces a super high Viscosity Index (VI) that is higher than mineral and synthetic base oils (HOBS avg. 220 VI compared to mineral oil and synthetic at avg. 100 to 140VI), providing an exceptionally higher VI with less mechanical and thermal shear, reducing viscosity breakdown. In addition, HOBS provide superior friction reducing properties and have virtually no volatility comparing to mineral and synthetic base oils. Incorporating these high performance benefits provide a more energy conserving formulation that increases fuel economy and reduces emissions. (Lubricity Enhanced Energy Conserving Formula)
