....for pouring the correct amount of oil when changing it.
Both of my Honda's need 3.7 qts. each....so instead of trying to get close with a gal container and then adding a little at a time (over and over) I do this.
I pour .3 quarts (or 9.6 fl ozs) into the measuring cup first.(I mark the line) Then just dump the rest of the gal container in the engine and it's the perfect amount. The 9.6 oz goes back in the empty jug to be used for the JD.
Maybe I'm not the first to do this...but it saves a lot of time sticking and wiping the dipstick.
