I change the oil here at my shop it gets done religiously every 3000 miles and we use oreilly brand synthetic 10-40 in the summer and 5-40 in the winter. Oil filters are oreilley generic (wix).


My first thought was I didn't get the drain plug or filter tight but I checked them and they are dry and tight... I also thought maybe I got distracted or something and didn't actually fill it up the last time but even after topping it up it still keeps dropping rapidly.
