The location of my exhaust pipe is directly next to the oil filter so I have to rub against it to get to the oil filter, which makes changing my oil hot kind of a chore, those pipes get pretty dang hot! Is there any difference in getting a used oil analysis on oil drained cool or mildly warm than hot oil?
 
similar situation on my '05 Civic. I pull the plug from the pan, take my sample then come back in ~15mins when the exhaust has cooled enough to reach up for the filter.
 
Yea, hot is good. But as long as the car has been thoroughly driven until the engine and oil is hot...it probably doesn't make a whole lot of difference if the oil cools down a bit. Probably hotter that just warm is probably O.K.

Drain the oil from the pan while hot.
You can then wait until the exhaust cools to remove the filter.
 
Now I just need to master taking out the drain plug without getting it all over my hands

Any tips?

I had the same thing happen to me. So,just recently, I decided to wear some cheap plastic gloves while draining the oil. That way,it's simply a matter of throwing the gloves away

I tried an oil extractor, I bought one of those cheap little plastic jobbies from Wal-Mart but I couldn't get the dipstick tube to get straight, it kept curling up on me. Returned it. As for the gloves, I use latex gloves whenever I change the oil, I wonder if that would be enough. I could also put a spare pair of my mechanix gloves over those...
 
Dollar store gloves is all I use.

I am curious as to how much oil is left in the bottom of the pan when using an oil extractor. Anyone here removed the drain plug after using the extractor? How many approximate ounces remained?

I researched extractors before getting a 7 liter Mitivac from Sears. Some people reported getting more with the extractor than with a drain. Others reported getting a tad less with the extractor. All depends on the dipsticks orientation to the lowest part of pan,or maneuvering the tube down there.On my Dads Craftsman rider mower(only time I`ve used it so far)it got all of it,1.5 removed,1.5 put back in. I parked it on a slight angle favoring the extractors side

The nitrile gloves Costco sells now are fantastic for protecting your hands during oil changes and all sorts of work. I buy 10-20 boxes of them per year and they are well worth it!

Fumoto valve and nitrile gloves - makes changing oil almost fun!




No way, that eliminates all the fun!

Yeah, it can't be an oil or filter change without some oil running down your forearm. You need that to prove to your wife that you have been outside working and not just playing.
