Lots of riders, and even some “in-the-know” magazine journalists, say all oils are the same. The FACTS are: engines, drivetrains and demands on motorcycles are different and so are the lubricants required.
Take power: maximum engine output per liter for motorcycles is typically 1.5 to 1.8 times that of automobile engines. Similarly, R.P.M.’s at maximum output are 1.3 to 2 times that of most automobiles. Further, motorcycle engines, being small and lightweight, have a smaller thermal capacity – the result is that motorcycle engine oils can reach temperatures as high as 320° F.
Motorcycle oils: 1- MUST contain higher quality shear stabilizers because many run the same lubricant in both the engine and gearbox. 2- MUST have higher volatility to control consumption because they do run hotter. 3- MUST have special additives to better prevent cam wear and oxidation in their extreme heat environment.
So does it make sense to skimp on your motorcycle’s “health” to save a few dollars per oil change? No Way! An average Motorcyclist changes their oil twice a year, using a less expensive oil to save only a few dollars -vs- using high quality motorcycle specific oils. That just doesn’t make sense.
