Yaris Oil Change DIY - Toyota Yaris Forums

I didn't know you needed to fill the new oil filter with oil before you put it on. So you fill it between half way and full? What's the purpose of putting oil in it?

I never did this with my old car, but will start doing it with my Yaris since my first oil change is coming up soon.

I think it's because all of the oil eventually flows through the filter and then the engine re-uptakes the oil from the filter. And perhaps when the ignition is started, the engine re-uptakes the oil directly from the oil filter. So if the ignition takes place and there is no oil in the filter (after an oil change), it's sort of like dry-heaving (puking without any food in your system). That's just my guess. Sorry.
