Federal regulations are dictating new diesel oil trends resulting in greater oil consumption.

AMSOIL’s position as the innovator over the decades sets the advantage to overcome these challenges early on.

By Chris Sharon, AMSOIL HQ

Using a good diesel oil is essential to keeping engine components clean and protected. But changing tides may be dampening the level of wear protection offered by some oils. To meet emissions standards, oil additives that protect the engine were reduced with the introduction of the API CJ-4 performance specification, in 2006. Reduced additive content may cause unforeseen consequences, such as increased engine deposits, which can lead to oil consumption. Without the cleaning power of these additives to reduce harmful deposits, some diesel oils on the market may be at the tipping point of achieving emissions goals at the expense of engine protection.

Cummins, for example, released a Technical Service Bulletin that addresses oil consumption outside of their warranty. The TSB recommends using a custom-formulated oil (which costs $66 per gallon) every 120,000 to 160,000 miles to prevent engine deposits. Considering that many over-the-road truckers can accumulate this mileage each year, most would face more than $600 in extra operating costs per year.

If you’ve experienced this issue, we recommend using AMSOIL Engine and Transmission Flush and switching to AMSOIL Premium 15W-40 Synthetic Diesel Oil. It offers excellent protection against wear and oil consumption while protecting modern emissions-control devices.

If you prefer an oil with a lower initial price, we recommend AMSOIL OE 15W-40 Synthetic Diesel Oil. In fact, it’s a great option if high oil consumption hasn’t yet been a concern, and you prevent potential issues by switching from conventional diesel oil to synthetic. AMSOIL OE Synthetic Diesel Oil meets the requirements for low-emission quality diesel oil and protects under the most severe conditions found in modern diesel engines.

  • Fortified Cleaning Power – AMSOIL OE Synthetic Diesel Oil is formulated with high-quality synthetic base stocks and detergent/dispersant additives that help prevent harmful engine deposits that can lead to premature wear, increased heat and increased oil consumption.
  • Excellent Soot-Handling – AMSOIL OE Synthetic Diesel Oil allows for optimal soot-related viscosity control to maintain stay-in-grade performance. It helps keep soot particles from agglomerating, helping to reduce engine wear.

As times change, we’ll watch trends and look toward affordable engine-protection solutions.

Noack Volatility

Low-Volatility motor oil helps unlock vehicle performance   To meet today’s strict motor oil specifications and adequately protect modern engines, motor oils must demonstrate increased resistance to volatility. Nearly 30 years ago AMSOIL became the first oil manufacturer in the United States to use the NOACK Volatility Test (ASTM D5800) as a measure of performance […]
