Dyna-Plex 21C Synzol HDEO is formulated with synthetic base oils and ultra-premium detergent and additive technology. This technology has demonstrated a 1% to 3% fuel economy in field tests in over-the-road trucks in the U.S. The optimized product still provides long-drain capability. The highly advanced additive chemistry complies with API CK-4 and numerous high-quality OEM specifications.
Dyna-Plex 21C SHPD Engine Oils are designed to extend drains in today’s heavy-duty diesel engines while providing outstanding engine protection. Dyna-Plex 21C SHPD oils are made using low-sulfur and high-saturate base stock for high oxidation stability on par with top shelf synthetics. Blended with the highest performance additive package available, SHPD’s exceptional formulation helps fight degradation and extend drain intervals for significant savings.
Dyna-Plex 21C Orion Natural Gas Engine Oils are premium low ash lubricants for natural gas fueled engines. They are formulated from a 100% paraffin base stock containing high performance, low ash additive package. Dyna-Plex 21C Orion Natural Gas Engine Oils have been formulated to provide exceptional deposit, wear, oil oxidation and oil nitration control in the high output, highly turbocharged natural gas engines. This low phosphorus package is designed to meet catalyst manufacturers’ requirements.
Dyna-Plex 21C Sargas Natural Gas Engine Oils are premium ashless lubricants for natural gas fueled engines. They are formulated from a 100% paraffin base oil containing a high performance, completely ashless additive package. Dyna-Plex 21C Sargas Natural Gas Engine Oils provide outstanding deposit, wear and oil oxidation control in naturally aspirated and supercharged natural gas engines. They do not contribute to spark plug fouling, pre-ignition or port clogging tendencies, and permit trouble-free engine operation with minimum maintenance. Dyna-Plex 21C Sargas Natural Gas Engine Oils have proven effective under the most severe operating conditions in extensive field service.
Dyna-Plex 21C Polaris Natural Gas Engine Oils are designed to reduce oil consumption and extend valve life in 2 and 4-cycle natural gas and LPG engines. These oils also reduce engine deposits in ring grooves, oil rings, piston heads and valve steams. The Polaris Natural Gas Engine Oils contain high levels of detergent alkalinity, which sufficiently cope with most commonly encountered levels of hydrogen sulfite in unprocessed natural gas to help reduce wear on engine parts. In addition, additives protect engines from rust and corrosion. A high degree of oxidation resistance extends life and prevents excessive wear. The zinc content in these oils is sufficient to protect lifters and cam shafts in engines which have been converted to natural gas service.
Dyna-Plex 21C Dezol Engine Oils are formulated with hydrocracked base stocks exhibiting synthetic blend properties, which counteract acids, varnishes and deposits to extend engine life and maintain peak efficiency. Dyna-Plex 21C Dezol Engine Oils provide outstanding protection against scuffing of highly loaded cams, hydraulic lifters and other valve train components, resulting in reduced engine wear and increased engine efficiency and power. Dyna-Plex 21C Dezol is an economical choice for fleets of diesel engines requiring an API Service Classification CK-4.
