Synthetic oil in the motor & diff.

Guy's does anyone have experience/knowlege in running synthetic oils in our Rhinos? if so what type, motorcycle (wet clutch) or automotive? Thanks all.

I read somewhere (another forum) that synthetics will not work with the Rhino clutch.

I think that is true. not 100% though. anyone else know?

Synthetic are great to use in your Rhino. The only thing we have to ensure is that you select an oil that is wet-clutch compatible and contains no friction modifiers.
Like Amsoil Formula 4-Stroke Power Sports or their 10w-40 or 20w-50 Advanced Synthetic Motorcycle Oil.
In the diferentials use Amsoil Severe Gear or their Long Life Synthetic Gear Lubes.

You will see a big diference in temperature drop, quieter motor and gear noise, fuel comsumtion and a small amount of performance increase.

That last post reminds me... I kinda remember what I heard now... it was not to get something with friction modifiers in it.

Thank you.

Thanks lwehr! Nice to clear that up. Any other brands available without friction modifiers?

Any syn oil that is ok for motorcycles is ok for the rhino, Mobil 1 makes one. There are a lot out there you just need to find them. [font=Arial Black:ca3c59a94b] [/font:ca3c59a94b]

That clears up one of the many mysteries In my life. Thanks all...

I always have more mysteries than answers :?

No truth what so ever. They only say that because they really don't know what they are talking about.

Do people really know what synthetic oil is?

Here is a simple explanation.

Synthetic lubricants are chemically engineered from pure chemicals rather than refined from crude oil. That gives them significant advantages over refined oils. The base stocks from which synthetic lubricants are made feature uniform and smooth molecular structures, which ensures low friction as lubricant layers slide across one another. Reduced friction increases energy through-put for greater fuel efficiency and power, and reduces heat and wear for longer equipment life. Molecular uniformity also helps synthetics resist thinning in heat and thickening in cold, which helps them protect better than refined oils over a system’s operating temperature range and helps ensure secure sealing.

Conventional oils – the oils most people are familiar with – are refined from crude oil. Refining is a process of physically separating light oil components from heavy ones. Crude oil contains a full range of different kinds of molecules. Many are similar in weight but not in structure. The refining process cannot distinguish such molecules, so a wide assortment of molecules is present in a finished lubricant made from crude oil stocks.

Energy Conserving: The “Energy Conserving” designation applies to oils intended for gasoline-engine cars, vans, and light trucks. Widespread use of “Energy Conserving” oils may result in an overall savings of fuel in the vehicle fleet as a whole.

FRICTION MODIFIER
Definition: Additives that reduce the friction of moving engine parts or oil flow in the engine.

Though 4-cycle motorcycle/powersports engines may be considered more similar to automobile engines than 2-stroke motorcycle engines, they still have very different performance requirements. Historically, 4-stroke motorcycles have had problems with gear pitting wear in the transmissions and clutch slippage. In many cases, this can be directly attributed to the oil used. Most automotive engine oil is developed to minimize friction and maximize fuel economy. Since the oil for many 4-stroke motorcycles is circulated not only through the engine [as with an automobile], but also through the transmission and clutch, different characteristics are required of the oil. First, a certain amount of friction is necessary to prevent clutch slippage. Second, the oil needs to prevent wear and pitting in the gears of the transmission. These and other essential characteristics are addressed in the standards developed by JASO for 4-stroke engines.

As with the 2-stroke classification, the JASO 4-stroke classification is also divided into grades, MA, MA2 and MB. MB is lower friction oil, while MA is relatively higher friction oil. Other than friction, the JASO 4-stroke classification tests for five other physicochemical properties: sulfated ash, evaporative loss, foaming tendency, shear stability, and high temperature high shear viscosity (HTHS). Sulfated ash can cause pre-ignition if the oil is present in the combustion chamber. It can also contribute to deposits above the piston rings and subsequent valve leakage. Evaporative loss and foaming reduce the amount of lubrication and protection in the transmission, engine, and clutch. With less shear stability, oil loses its capability of retaining original viscosity resulting in increased metal-to-metal contact and wear. High temperature high shear viscosity tests provide viscosity characteristics and data under severe temperature and shear environments.
