Emissions for off-highway equipment In the non-road mobile machinery (NRMM) or off-highway marketspace, emissions are equally as key for new equipment. The European Commission has maintained the ‘Stage’ standards, with Stage I being introduced in 1997.
The latest standard that equipment manufacturers must adhere to is Stage V, which was adopted in 2019 for all new equipment, albeit with some delays to the implementation timeline due to the impacts of the COVID-19 pandemic. PM and PN limits were significantly tightened when compared with the previous standard. As a result, OEMs are expected to adopt diesel particulate filters (DPFs) across a broad spectrum of powerbands.

with E6 remain relevant for lubricants, the continued increasing focus on efficiency and emissions has led to changes in engine hardware design, which in turn creates new challenges for OEMs.

Preparing for the ACEA E8 Transition In 2020, lubricants aligned with the low SAPS ACEA E6 performance profile represented roughly one third of the European market. Based on Lubrizol estimates, we expect to see that market share grow to over half of the total market, whilst more than one-third of lubricant demand in Europe will be aligned with the SAE 5W-30 viscosity grade or lighter. The European lubricant market is upgrading to higher performance lubricants, which are enabling the latest generations of engine hardware.
Over the span of a decade, ACEA E6 has been a baseline that balanced the need for exhaust after treatment device (ATD) compliance without compromising on other key factors like engine durability. However, the penetration of vehicles fitted with DPFs and selective catalytic reduction (SCR) continues year on year, driving demand for low SAPS lubricants. Whilst the chemical limits introduced

The lubricant market is steadily upgraded by the hardware in the vehicle parc. In the background, another lubricant upgrade is underway. ACEA E8 was launched in 2022 with the changes to the ACEA sequences. This will eventually replace ACEA E6 and is a significant increase in lubricant performance.
Three tests were brought into the sequence. Two tests – the Volvo T-13 and Caterpillar Oil Aeration Test --align with API CK-4. (In addition, the Daimler OM471 test replaces the OM501LA test. These three tests address the lubricant performance areas of oxidation, aeration, and piston cleanliness respectively.
