class=\"ez-toc-section\" id=\"acea_c2_vs_c3\"><\/span>acea c2 vs c3<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>ACEA C2 and ACEA C3 are both engine oil specifications that are stable and stay in grade, but they have different uses and properties:<br \/>\nACEA C2<br \/>\nDesigned for passenger cars and light duty gasoline and diesel engines, ACEA C2 oils are suitable for extended oil drain intervals. They are low friction and low viscosity, and are compatible with aftertreatment systems. ACEA C2 oils are similar to ACEA C1 oils, but have a slightly higher SAPS limit.<br \/>\nACEA C3<br \/>\nDesigned for modern light duty diesel and high performance gasoline engines, ACEA C3 oils are suitable for vehicles with three way catalysts (TWC) and diesel particulate filters (DPF). They are stable, stay-in-grade oils with a mid SAPS level. ACEA C3 oils have a minimum High Temperature\/High Shear (HT\/HS) viscosity of 3.5 mPa*s.<br \/>\nACEA C2 and ACEA C3 oils have similar chemical limits, but different HT\/HS figures. A lower HT\/HS number provides better fuel economy, but it may not provide the same protection levels.<br \/>\nACEA oil sequences are designated by a two-part code, with a letter to define the class and a number to define the category. For example, ACEA C2 is a class C oil with a category of 2.<\/p>\n<p>C2\/C3 oils are specifically designed to be low-SAPS (sulfated ash, phosphorus, and sulfur) to prevent clogging of DPFs (diesel particulate filters), while A3\/B4 oils can have higher SAPS levels and may not be as suitable for such systems; generally, <strong>A3\/B4 oils might offer slightly better engine protection in certain situations, but may not be as fuel-efficient as C2\/C3 oils.<\/strong><\/p>\n<p>&nbsp;<\/p>\n<p><strong>What does ACEA A3 B4 mean?<\/strong><br \/>\nA3\/B4 oils are used in high-performance and direct-injection diesel engines. They can also be used instead of A3\/B3-grade oils. A5\/B5 oils are low-friction, low-viscosity oils with a high temperature\/high shear rate viscosity.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The ACEA (European Automobile Manufacturers Association) standards for engine oils are a set of specifications used to define the performance requirements for motor oils in Europe.
