15/40 of your choice just be sure to run after change at idle then CHK again to make sure it's full

No tricks, very straight forward. Last time I changed the oil I figured I'd buy the good stuff at $12 a quart. My gf comes out and starts talking to me while I'm pouring in quart after quart. Checking the oil fill window over and over wondering why nothing was showing up. Then after all 3 quarts were emptied I noticed I hadn't put the drain plug back in. They were all emptying into my oil pan just out of sight and mixing with the old oil I had just drained so I couldn't even salvage it. Knew I would do that at least once in my life but I swear never again!

Yes sir gf can do that you especially if they're wearing next to nothing on.  Done somethings the same in the past. You live you learn as grandpa used to say.
