ACEA A3/B4 | Truck & Commercial Vehicles

Oil for trucks and commercial vehicals - the performance counts

The engine oil for trucks and commercial vehicles is in no way inferior to the oil of cars. Their job is also the perfect lubrication and cooling of the engine. However, engines of trucks and commercial vehicles are significantly larger than car petrol and diesel engines. This in turn provides for different performance and conditions. Low-viscosity engine oils or oils with extremely low viscosities are not required. These low-viscosity oils would not withstand the high pressure loads. Metal surfaces rub against each other and their residues are absorbed by the oil. The oil loses its lubricating properties and ultimately results in an increased risk of wear. Thus, a 5W-30, 10W-40 or higher viscosity is required. Due to the displacement, the truck and commercial vehicle engines also have a larger volume. This must be lubricated with significantly more liters of oil. The purchase of 1 liter bottles would therefore be inadvisable. For this reason you will find in our shop those engine oils in the containers of 20 liters, 60 liters and 208 liters.


What does ACEA A3/B4 mean?


ACEA A3/B4 engine oils are often 5W-30, 5W-40 or 10W-30 oils that are usually targeted at modern passenger car gasoline and diesel models from various manufacturers.

ACEA A3/B4 5W-30 and 5W-40 engine oils are usually based on API Group III base oils, while ACEA A3/B4 10W-40 engine oils often contain both Group I, Group II and Group III base oils.

For the ACEA A3/B4 specification, an HTHS viscosity greater than or equal to 3.5 cP is required.

Since 2004, the European ACEA (Association des Constructeurs Européens d'Automobiles) has continued to develop the ACEA A3/B3 specification and revise its requirements:

  • ACEA A3/B4-21
  • ACEA A3/B4-16
  • ACEA A3/B4-12
  • ACEA A3/B4-10
  • ACEA A3/B4-08
  • ACEA A3/B4-07
  • ACEA A3/B4-04


Which viscosity for ACEA A3/B4 engine oil?


Which viscosity you can use in connection with the ACEA A3/B4 viscosity, depends strongly on your vehicle and/or the installed engine. In the vehicle manual of your car you will find a detailed description of how you should select your engine oil.

In the online store of ATO24 you will find ACEA A3/B4 oils of various viscosities. Hereunder are among other things:


If you are not sure which viscosity to use for your vehicle, just ask! The ATO24 team will be happy to help you quickly and competently to find exactly the right engine oil for you!

ACEA A3/B4 with approval / recommendation for Mercedes, BMW, Ford, Volvo, Renault etc.


In the ATO24 store you will receive engine oils that, in addition to the specification, also receive various manufacturer releases or manufacturer recommendations. Often specification and release occur together to narrow down the compatible selection of engine oils for you and make your search easier. Here you will find engine oils that also receive the following manufacturer recommendations and approvals:
