Im draining my oil right now. Bucket shows just at 6.5 quarts. I am using rhino ramps under the front wheels on a perfectly level surface. Is it better to leave it "level" to get most the oil out or is it designed for an incline? I know the motor drinks 6.9 quarts so its not much but as long as Im DIY , I'd like to get out as much as possible. Right now its been 20 minutes and Im still seeing a hair thin line drooling out. think it helps to dump a 1/4 quart in when most is drained to kind of rinse off the bottom of the pan maybe catching any debris along the way?
