Combating Soot Loading
TBN STABILITY AND WEAR PROTECTION IN MODERN DIESEL SYSTEMS
The EGR Problem
Modern diesel engines equipped with Exhaust Gas Recirculation (EGR) systems face a unique challenge: they are effectively "breathing" their own exhaust. This process significantly increases the amount of soot (carbon byproduct) that makes its way past the piston rings and into your engine oil.
The Chemistry of Dispersion
In a standard oil, soot particles tend to find each other and "agglomerate" into larger, abrasive chunks. These chunks act like sandpaper on your bearings and cam lobes. AMSOIL Diesel formulations utilize advanced dispersant chemistry that keeps these soot particles tiny and suspended in the oil, preventing them from grouping together and causing mechanical wear.
Total Base Number (TBN) and Acid Neutralization
Soot isn't just abrasive; it's acidic. As soot levels rise, the oil’s Total Base Number (TBN)—its ability to neutralize acid—begins to drop. Once your TBN is depleted, your engine is vulnerable to corrosive wear. AMSOIL is engineered with a high starting TBN to ensure that even under heavy towing or long-haul commercial use, the engine remains protected from acid-driven pitting.
The K&M Performance Commercial Solution
Whether you are running a single 1-ton Powerstroke or managing a commercial fleet, the goal is the same: Maximum Uptime. By choosing AMSOIL through K&M Performance (Dealer #30543586), you are investing in a lubricant that is proven to handle 4X more soot than required by the API CK-4 standard.
- Extended Drain Intervals: High TBN retention allows for longer service life without sacrificing protection.
- Turbocharged Stability: Resists thermal breakdown in the extreme heat of diesel turbo chargers.
- Cold Start Protection: Synthetic flow properties ensure oil reaches critical top-end components instantly, even in freezing temperatures.
