All lubricants for your car  - buy at ATO24!

For reliable, safe and low-wear operation, the right lubricants and operating fluids are essential for a car, be it a passenger car or commercial vehicle. Lubricants and operating materials are mainly classified as liquids, such as oils and coolants, as well as more solid substances such as greases. The wear protection and performance development of a vehicle are subject to several different properties of these substances. An essential function of oil or grease is obvious: the lubrication of vehicle components such as engine, transmission, steering and chassis. This contributes to achieving the desired performance and protects the vehicle from wear and tear. Another, but equally important, function quickly fades into the background: cooling the components. Especially in the engine and transmission, the cooling function of the oil is existential, alongside the coolant in the vehicle's water circuit! Operating fluids such as brake fluid or hydraulic fluids play a key role in the safety of a vehicle. These are also exposed to high thermal and physical loads, which is why consistent performance is important. ATO24 is your competent partner from refilling the engine oil to the complete engine, coolant or transmission oil change.

What does 5W-40 mean?

The designation 5W-40 indicates the viscosity of your engine oil in a so-called SAE class. Briefly explained, there are two components of the specification: The number before the W stands for the viscosity of the engine oil in winter (index W) or in cold condition. The other index number refers to the fluidity in warm or operating condition.

A 5W-40 and a 5W-30 engine oil therefore have the same flowability at cold start. At operating temperature, a 5W-40 oil is more viscous. In order to be able to evaluate these characteristics for their effect on the protection of the engine, always the individual case is to be lit up.

Mix 5W-30 and 5W-40?

In principle, you may mix a 5W-30 and a 5W-40 engine oil - for example, if your engine has too little oil available and you do not have any engine oil in the correct viscosity at hand. In any case, you should make sure that specifications and approvals are adhered to in addition to the viscosity.

In the long run, mixing 5W-30 and 5W-40 engine oil is suboptimal because, depending on the mixing ratio, the actual viscosity of your engine oil will approach the mixed oil.
