i forgot wad is the nos. for but the lower the better...
juz sharing ...
the viscosity grade (for example, 5W-30) tells you the oil's thickness, or viscosity. A thin oil has a lower number and flows more easily, while thick oils have a higher number and are more resistant to flow. Water has a very low viscosity - it is thin and flows easily. Honey has a very high viscosity - it is thick and gooey.
multi-weight oils (e.g. - 10W-30) are a new invention made possible by adding polymers to oil. The polymers allow the oil to have different weights at different temperatures. The first number indicates the viscocity of the oil at a cold temperature, while the second number indicates the viscosity at operating temperature.
