Transitioning from 5W20 to 5W30
What is the best way to change oil types, given that only about 4 quarts come out? I'd like to move to 5W30 in my new R3 at the next (2nd) oil change at 3000 miles. Should I drain, refill, run then change oil and filter? Is it ok just change normal and change again in 3000 more miles running mixed? I know there are many, many threads on oil, didn't see this answered though. Thanks,

Is that a bike rack?

there is a method whereby you take out the drain bolt and raise and lower each side of the car one side at a time... this helps to get as much oil out as possible. However when you refill, you need to take note of how much oil you drained out. Some people get as much as 5 qts. out.

Just start using the new oil type. They are all compatible. In fact, very very few oils hold their viscosity to 3,000 miles in our engines anyway, so the oil you are draining is below 5w20, and at 3,000 miles of 5w30, it will be below the 5w20 you have now.
the "types" are literally just thicknesses. It's not like one is water and one is oil paint and one is whipped cream and one is liquid silicone and one is sludge.

Great, thanks all! I'm an RX-8 newbie, after having a Miata the past 8 years. I'm still trying to understand why folks say the RX-8 is slow..... sure drives quick to me.

Except the answer to his question isn't exactly common sense. Without some background with oils, the question of whether oils of different viscosities will just blend into each other is an intelligent one. One can't assume they will.

The label don't mean a whole lot. I have tested a bunch of samples of different oils in my 8 and if I didn't post the weights you would have a hard time figuring out which was which. Some oil just break down quicker than others in as soon as 1000-1500 miles.

This was posted in another thread on here, but its so good it deserves a re post. This tells you everything that you ever wanted to know about oil and probably more.

Since rotaries burn oil, it seems to me the best way to "phase-in" the new oil is to just start topping-off with the new oil. Eventually all the old oil will be gone.

Unless you're changing from one synthetic to another, there's really no need to worry about draining the maximum amount of oil. If anything, a gradual change is going to be easier on your engine.
