0W Synthetic Oil

[usrodeo4]

I read something a while back that said 0W syn oil was being used by almost all the F1 teams now and was wondering if anyone is using it in their scooter? I was considering going to it at my next oil change....0-40W i would assume. Thoughts?

i would use the 5-40 or whatever is recommended for the s1000

Good advice... keep in mind that the engine builders (of F1, built motorcycles, etc.) may have different tolerances that allow them to use a lighter oil too. That said 0W-40 is only lighter when it's cold... that's the "0" number... when it's hot, it's still operates like 40W.

DONT USE!
i tried alysin 0wt oil in my bike, didnt gain any power, and trans started shifting notchier. im now using 20/50 non synthetic since i drag race often.

isnt it the other way around me ol mate....????????

10-40w

the ten is when its hot (less viscous (thinner) and hot) ???????????

and the 40 cold (thicker and cold) ??????????????

The Winter rating of an oil is not a weight- it's a number that's derived from a mechanical test (Cold Cranking Simulation) that measures an oil's ability to function at very low temperature (-25C). All oil is thick when cold, and thins as it heats. The Winter rating should not be confused with an oil's operating viscosity (the 40 in 5W-40), which is a measure of an oil's viscosity (thickness) at 100C (212F).

It is very important to follow a manufacturers' recommended oil weight (operating viscosity), but the Winter rating can vary depending on the climate where the bike is being operated. Again, the operating viscosity-the second number, is the most important number. The Winter rating really only matters in cold climates.

Be aware, however, that it takes more additives to make a multi-grade oil with a large range from the Winter number to the operating weight number (for example- a 0W-40 versus a 15W-40). These additives are prone to shearing inside a wet-clutch (motorcycle use), and therefore tend to break down more rapidly than in oil with less additives. In short, a 0W-40 should not last as long as a 15W-40 in identical operating conditions. Therefore, it's best to use an oil with the highest Winter number for the lowest temperature the bike will be operated in, and use the highest operating viscosity approved by the manufacturer. This will give your engine the highest level of protection.

Nope... It means that when the engine is cold, it acts like a 10 weight so it starts to flow easily, coats surfaces faster and brings up oil pressure faster and when it's hot it acts like a 40 weight and resists becoming too thin...

Umm... not correct. As stated in the above post oil gets thicker as it cools, and thins out as it heats up. Cold oil is thick, hot oil is thin. The W (Winter) rating of oil designates how low of a temperature the oil can remain functional- the lower the number, the lower the temperature. Although the number is low, it still means the oil is much thicker at low temperature than when the oil is warmer. Do not confuse this with a viscosity (or weight) measurement- they are two different things.

The viscosity of an oil is a measurement of how much oil will flow through a measuring device at 100C (212F). This is the operating temperature of oil and is what gives it it's "weight" (the 40 in 5W-40). The 5W (or Winter rating), as explained above, is a different measurment that rates an oil's ability to function at very low temperature (-25C).

All oil is thicker at low temperature and thinner at high temperature- there's no way around this fact. That's why it's very important to warm your engine before stressing it- the oil is not at the correct operating viscosity until 100C! Imagine what's happening inside the engines of the knuckleheads who start it cold and immediately bang it off the rev limiter... makes me shudder to think.

Thought so !!!!!!

Nope.... What Hampton said... the first number is the cold number rating... the second number (bigger one) is the hot number rating.
