Buy Rally/Racing oil online at ATO24

Racing stands for high speeds, temperatures and stresses for the motorcycle. An engine oil in the Racing area must be tailored to these specific requirements. Whether it is for the type of engine to a 2-stroke or 4-stroke engine. With us you will receive a special racing motorcycle engine oil of the premium brands Ravenol and Amsoil. We do not offer Castrol for the reason that we offer Ravenol and Amsoil oils with a higher standard. They overrun the normal oil standards.

Racing oil for 2-stroke und 4-stroke engines

The matching Racing motorcycle oils are available in the viscosities of 15W-50, 5W-50, 10W-60 and 10W-50. In addition, also special oils for 4-stroke and 2-stroke engines. The bottles are available in the containers of 0.946 liters up to 20 liters. Our Racing and Rally oils are not available on Amazon or Ebay. As a customer, you just profit of it. Cause you pay less for delivery service and get a phone consultation. So give your motorcycle the best oil for racing conditions - namely Ravenol or Amsoil.

Buy 10W-40 Oil: Huge selection, top prices

In the ATO24 online store you get exactly the right 10W-40 engine oil for your vehicle! In addition to top prices, we offer you reliable advice and help you find the right 10W-40 oil.

The viscosity SAE 10W-40 belongs next to 5W-30 to the most demanded engine oil viscosity. But what exactly does 10W-40 actually mean and why are there so many different oils despite the same viscosity? We will clarify these and other questions in the course of this blog article.

What does 10W-40 mean?

10W40 stands for a multigrade viscosity. Correctly written out as 10W-40, the two viscosity indexes given, 10W and 40, refer to all-season use (suitability for winter and summer use). These multigrade oils were developed over 50 years ago and were intended to replace the procedure of having to change oil at summer and winter time. The viscosity specification in cold (10W) and warm (40) viscosity indicates the oil's flowability at high and low temperatures.

10W stands for the flowability in winter (this is where the W index comes from). The value 10 is not a directly measurable value of a certain unit but an index number. The lower the number before the W, the better the flowability at cold temperatures and cold starts. A 5W-30 engine oil therefore has better flow properties in cold conditions than a 10W-40 engine oil.

The number 40 stands for the flowability of the oil at a temperature of 100 degrees Celsius. Again, the lower the number, the lower the viscosity at a temperature of 100 degrees. Accordingly, a 10w40 engine oil is more viscous than a 0W-30 engine oil.

Buy 10W-40: Here's what to keep in mind!

Even if the vehicle manual recommends a 10w-40 engine oil, the right 10W40 oil is not immediately found. When buying a 10W-40, attention must be paid to the prescribed specification and release. They represent the particular chemical properties of an oil.

10W-40 engine oil approvals

As always, your vehicle may require a release in addition to the 10W-40 viscosity. These approvals are listed on the bottle label next to the specifications. The best known approvals are those of BMW (e.g. LL-04), VW (e.g. VW 507 00) and Mercedes Benz (e.g. MB 251.0). The approvals with the engine oil are comparable with a quality seal of the automobile manufacturers. Thus this manufacturer issues a certain chemical characteristic of oils, which must be fulfilled, in order to be permissible for the cars from the own product series.

What engine oil approvals occur together with viscosity SAE 10W-40? Among many others, are common engine oils of the following releases and recommendations 10W-40 engine oils:

• BMW Special Oil 10W-40 Engine Oil
• Mercedes-Benz MB 229.1 10W-40 Engine Oil
• VW 505 00 10W-40 Engine Oil

What is the difference between 10W-30 and 10W-40?

Both viscosities share the winter property "10W", which means that they have the same properties at low temperatures and cold start. The indices 30 and 40 refer to a difference at high temperatures. Thus, the 10W-40 shows a slightly higher viscosity at high operating temperatures. This difference can be advantageous if the engine has oil losses with a 10W-30 motor oil.
