What is ACEA oil classification?

What is ACEA oil classification?

Unlike the API, ACEA has three main groups – “A/B”for petrol (A) and light duty diesel (B) engines, “C” for light duty three way catalyst (TWC) and Diesel Particulate Filter (DPF) compatible oils, usually Low and Mid SAPS (Sulphated Ash Phosphorus Sulphur) and “E” for heavy duty diesel engines.

What does the ACEA specification relate to?

The ACEA specification tells you that an oil meets their standards. The performance of the oil is broken down in to different categories: A = Petrol, B = Diesel, C = Catalyst compatible or low SAPS (Sulphated Ash, Phosphorus and Sulphur).

What does ACEA A5 or above mean?

ACEA A5/B5 oils are Upper Mainline lubricants. They are designed for use in high performance gasoline and light duty diesel engines that are specifically designed to use a low viscosity oil. These oils may be unsuitable for use in some engines.

Is ACEA C3 better than A5?

The main difference between the two specifications is the high-temperature high-shear viscosity at 150 C which has to be between 2.9 cP and 3.5 cP for A5 and >3.5 cP for C3.

What does ACEA A3 B3 mean?

ACEA A3/B3 oils are Mainline lubricants. They are designed for general usage use in a wide range of gasoline and light duty diesel engines. ACEA A3/B3 oils are typically used in older vehicles as they do not provide the minimum performance demanded by the latest OEM specifications.

What does ACEA C3 mean?

ACEA C3 oils are Top Tier lower SAPS1 lubricants. They are designed for use in high performance gasoline and light duty diesel engines where advanced aftertreatment systems such as Diesel Particulate Filters (DPFs) and Three Way Catalysts (TWC) are used.

Can I use ACEA C3 instead of A3?

C3 fulfills all the A3B4 requirements, so it should be alright. Due to the lower SAPS content you could think about replacing the oil earlier.

Can I use C3 instead of A5 oil?

ACEA C3 will be fine.. You wouldn’t want to run A5/B5 in a car that had a catalytic convertor but the other way around is fine. Make sure weight and blend is right (5W-40 fully synthetic IIRC?) and you’ll be fine.

What is ACEA A3 B3 A3 B4?

ACEA A3/B4 oils are Upper Mainline lubricants. They are designed for a use in high performance gasoline and light duty diesel engines and are typically used in newer vehicles as they provide the minimum performance demanded by many OEM specifications.

When should I switch from 5w30 to 5w40?

5w40 is better for starting your engine at low temperatures as it flows more easily in this environment. When the engine is running and hot, the differences are negligible; 5w40 and 10w40 both have high viscosities and are equally effective in protecting against engine wear.
