Big rigs are taking a sigh of relief as California's zero emissions standards are delayed. But should they be worried? As vehicle pollutant emissions standards have become stricter, one fuel has remained out front. Synthetic diesel oils continue to deliver lower emissions than the limits mandated by tightening emission standards.
Synthetic diesels are becoming the preferred oil for big rigs and farm tractors because they are doing more than lowering emissions. While enjoying the clean fuel benefits of heavier duty diesel, including the max duty synthetic diesel oils, your fleet will also benefit from overall higher engine performance.
Improved Fuel Consumption
If you want to maximize fuel economy, you need to keep your engine operating at peak performance. But because high sulfur fuels cause more damage and stress to engines, they burn more fuel. Damage from sulfur particles and low lubrication in high viscosity fuels beat up on engine parts.
Synthetic diesels not only reduce or eliminate sulfur. They also eliminate greenhouse gases, nitrogen, and particulate matter. As these diesel fuels become lighter on emissions, they are getting tougher against engine wear and corrosion. With parts operating optimally, your engine's combustion efficiency is improved. By cleaning pollutants out of your engine, both power and fuel economy are improved.
If you're operating a fleet of heavy duty diesel fuel vehicles, then you know well the traditional trade-offs between heavy and light diesel fuels. Diesel fuels provide higher fuel efficiency and lower emissions for your heavy duty vehicles. Their poor lubricating performance under extreme temperatures, however, slows oil flow through fuel lines. Yet lighter oils can provide less protection to rings, cylinder liners, and other engine parts.
With synthetic diesel oils, you no longer have to compromise. Like light duty fuels, synthetics provide low viscosity, and therefore superior wear protection. By providing strong soot thickening resistance and dispersion properties, soot particles cause less damage to parts. Impressively, heavy duty diesels such as max duty diesel oil 15W-40 are reporting orders of magnitude improved wear protection than that required by Detroit Diesel DD13 Scuffing Test standards.
Under extreme weather conditions, synthetic oils are outperforming here, too. The ability of max duty synthetic diesel oils to retain their stability under high and low temperatures keeps fuel running smoothly through the fuel lines. The improved fuel flow further protects parts from wear.
You may pay more for synthetic diesel oils. But the performance advantages will pay for themselves by producing more fuel efficient and longer-lasting engines.
