10W-30 | Transmission Fluid

Buy Transmission Fluid online at ATO24

The motorbike gear oil is only used for a few bikes. The reason for it is that in many motorcycles, the gear is lubricated by a normal engine oil. Bikes with an extra gear lubrication need a specific transmission fluid. In this case, if you use a normal engine oil, you damage the gear.

Bevor you buy a gear oil you have to check the specific clearances like SAE or API. SAE specification tells you which viscosity the motorcycle gear needs. For example 10W-30 or 75W-90. 75W in this case stands for the temperature resistance in the winter. The second number of disclosure applies to the summer time. The API GL Designation deemed labeling for requirements for oils and hence the transmission oil. Transmission fluids are usually marked with API GL-4 or API GL. 5 API4 in this case stands for a gear oil for severe conditions. They are offset to a small extent with additives to meet these requirements. API GL-5 is for use in harsh conditions. They also contain more additives as a gear fluid with API GL 4 marking. The additives are each used to reduce wear. How many liters of transmission oil the bike needs, see the Motorcycle manual. Otherwise, we can give you an telephonic support.

Engine oil 10W-30: Large selection, wide range, top prices at ATO24

You are looking for a suitable 10W-30 engine oil for your vehicle? In the online store of ATO24 you are right!

We help you to find out what is important for your vehicle and to buy exactly the right one from our large selection of SAE 10W-30 engine oils. In addition to our competent advice, we offer you attractive prices.

In addition to the engine oil viscosity SAE 10W-40, oils of the viscosity class SAE 10W-30 are among the most demanded engine oils with the cold viscosity 10W. But what exactly does 10W-30 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-30 mean?

SAE 10W30 is what is known as a multigrade viscosity. Correctly written out as 10W-30, the two viscosity indexes given, 10W and 30, 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 (30) viscosity indicates the flowability of the oil 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 when cold than a 10W-30 engine oil.

The number 30 stands for the flowability of the oil at a temperature of 100 degrees. Again, the lower the number, the lower the viscosity at a temperature of 100 degrees. Accordingly, a 10w30 engine oil here is comparable to a 5W-30 engine oil.

Buy 10W-30: There is to consider!

Even if the vehicle manual recommends a 10w-30 engine oil, this does not immediately mean that you have found the right 10W30 oil. When buying a 10W-40, attention must be paid to the prescribed specification and approval. They represent the particular chemical properties of an oil.

10W-30 engine oil approvals

As always, your vehicle may require a approval in addition to the 10W-30 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-30? Among many others, common engine oils are of the following clearances and recommendations 10W-30 engine oils:

• Chrysler MS-6395 10W-30 Engine Oil
• Ford WSS-M2C171-E 10W-30 Engine Oil
• MB 228.31 10W-30 Engine Oil

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

Both viscosities share the "10W" winter property, which means they have the same properties at low temperatures and cold starting. 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.
