Rotella T5 is available in two viscosity grades: 15W-40 and 10W-30. The 15W-40 grade is thicker and provides more protection in high-temperature conditions, while the 10W-30 grade is thinner and provides better flow in low-temperature conditions. Another less popular grade is also available which is Rotella T5 10W-40 CJ-4
The numbers without the W are all tested at 210° F or 100° C which is considered an approximation of engine operating temperature. In other words, a SAE 30 motor oil is the same viscosity as a 10w-30 or 5W-30 at 210° (100° C). The difference is when the viscosity is tested at a much colder temperature. For example, a 5W-30 motor oil THE 10W30 OIL & ITS BENEFITS. The 10W30 oil – While still quite “fluid”, this oil is a little bit thicker at low temperatures than the 5W30 oil, making the process of starting your engine a little bit harder. It is recommended for use at -13°F up to 95°F / -25°C up to +35°C (outside temperature). 98. Location. MD. Feb 10, 2020. #1. Here's a two'fer of T5 Rotella. The 15W-40 I was testing for my truck and the 10W-30 for my motorcycle, trying to follow Honda's recommendation of no moly in the oil (yes I realize it's not JASO MA rated). The 10W-30 indeed had no (significant) moly so I'll probably try it out after my Actevo runs its course.

10w30 vs 15w40. The key difference between 10w30 and 15w40 motor oil is that 10w30 motor oil does have a viscosity grade that flows like ten-weight oil when the weather is cold or even the engine temperature is low. It can also resist thirty pounds while the engine is at its maximum temperature. The viscosity of 15w40 motor oil is comparable to

For instance, SAE 5W-30 oil flows better at colder temperatures than 10W-40 oil. But, SAE 10W-40 oil is thicker. It provides better protection in warmer weather compared to SAE 5W-30. Multi-viscosity engine oils don’t behave the same. It depends on the operating temperature. A multi-viscosity oil provides good flow in cold weather and
Unless you are a heavy weight?. meaning over 270#'s I suggest you try 15w fork oil. I tried them all in my bike and yes I can feel the difference between 5w oils. 20W was to firm. 15W was better but I wanted to try 10W the next time a seal gave me an issue to see if I could get a smoother ride?..
There is a difference between 10w40 motor oil and 20w40 motor oil. However, there are not many differences at all. So let us get to know the differences between 10w40 motor oil and 20w40 motor oil in terms of viscosity, fuel economy, and hot weather. Viscosity. The 10w40 motor oil means that the 10w meant winter. It means that the motor oil
Let the owners manual for your vehicle help you decide. The manual for my 3.8L Buick says SAE 30 oil is preferred unless the cold start-up temperature is below 32ºF (0ºC) for several times between oil changes. It further says that 15W-40 should be used in other situations, but recommends not using 10W-40 as it could void the warranty.

Premium Blue On Solution Gen2 is being marketed a universal mixed fleet oil for diesel, natural gas, and
161 posts · Joined 2006. #1 · Apr 23, 2008. I understand the technical difference between 5wt and 10wt fork oil is the viscosity, which is the ability of the fluid to flow at a defined temperature but is there much difference in the feel at the handlebar with similar damping settings dialled into the fork. Anybody got any experience of using Bmdn.
