hey.. i remember hearing something about how the engine doesn't like it if u keep switching oils on it. does this mean, it doesn't like it if u change the brand of oil or the type of oil (for instance 5w-20 something like that =P)?

what's that mean?
I saw those on the bottles but don't know what it means.
I think it is the weight of the oil at cold and warm temperatures. Start up and running temp weight, in other words.

5w-30 means the range of weight of oil that bottle has. So the oil has a mixture of oils ranging from 5w to 30w. You can also get 0W.

At least that is how I understand it. Please if anyone else knows more let us know.

I went and looked for info to back up my previous post and this is where this comes from. http://www.howstuffworks.com/question164.htm
"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."

I was wondering if anyone knew if it was possible to change the oil yourself on the is300. Is the oil filter accessible and is it tough to get under the car to drain the oil.
