So I'm down for my oil change last night and brilliant me decided to do it at the same time I'm tearing down the front shock on my Klein Attitude. I fubar'd the front wiper seals like nobody's business and decide to save face and cool off by finishing the oil change. Drain old oil, check. Change filter, check. Fill with 5.5 quarts of Mobil One, check. Close Fumoto valve, uncheck.
I caught it as the first quart was draining. Then I started to do some scientific calculations in my head. The oil filler neck is much bigger than the Fumoto valve and I caught it on the first quart just as it was emptying, I must have only lost 1/2 quart as it travelled down to the oil pan. So I'll just add the extra 1/2 quart, right?
Double check everything and make sure it is buttoned up. Drain old oil back into 5 quart jug and it overfills it plus a little extra (those 5 quart jugs are never filled to the top anyways) so I'm feeling good about my 'calculations'. I go to check the dipstick (something I admittedly never really do since I ALWAYS put in 5.5 and it IS a Toyota) and there is no way to read anything! Oil smeared on both sides no matter what combination of in and out or wiping I do. Bent rods briefly swirl through my head. I grab the keys to the wife's car and almost make it out of the garage on my way to pick up more oil thinking I'll just drain it again and refill for piece of mind.
Finally I say f*** it, I'll check it in the morning, oil should have settled by then. Get up this morning. Check the dipstick. Oil smeared all up and down both sides. I decide to experiment with what the dipstick looks like if I drain a little from the valve. Seems to be lowering a little. I have officially pulled the dipstick out enough times to make up for all the other times I have never checked and I am now questioning the life cycle of the o-ring near the pull. Also, as I am now an expert on dipstick readings, I have figured out that dimples facing the firewall give the most accurate reading. By this time I have drained 3/4 quart and notice the dipstick may or may not be just above the top dimple.
I feel safe enough to finally start the truck. It runs! I let it idle for a few minutes then shut it down so I can check the dipstick another 50 times. About 15 minutes later I get a decent reading and it is 3/4 of the way to the top dimple. I guess some stayed in the filter? So I add a little and walk away.
