Insert a funnel into the oil filler hole.

Scion recommends 0W-20 oil for low temperature climates, and 5W-20 for moderate and warm climates. We broke all the rules and used 5W-30; it is easier to find and better than 5W-20 for especially hot conditions.

Use one hand to hold the funnel steady in the filler hole. Pour 4.5 quarts of oil into the funnel.

We know you don't want to do math, so here's some math help! If you are using a handy-dandy 5 liter jug of motor oil, you will be left with just under .8 quarts in the bottle.
