Weather was in the 70s and delightful during right before sunset. Not too warm or cold. The time has come to swap oil that has been there for a while.
Observations. The stainless steel cooking pan comes awfully handy for oil changes. It has served me well for 25 years. I think I've used it for oil changes only in the past 15. I cannot believe I've had it that long. It's durable and does not break or disintegrate like plastic units.
If you need an emergency cooking pan, you can always clean it up and enroll it in that task.
The mattress or the futon type cover comes in very handy also. It's about 1" thick or so but very comfortable to lay on to do automotive tasks.
I always forget the size of the socket. youtube incorrectly told me 15mm. Don't believe everything you hear on the internet. It's actually 13mm for Chevrolet 6.0L 2006 vintage. I love sockets versus wrenches. The snap-on ratchet is nice. I also have a matco which is a pretty good copy.
The last time I changed the oil, I did not change the oil filter. Perhaps not entirely wise, I know. I won't repeat it, since I got a good deal on Purolator filters and have enough for 3 years sitting here.
The best oil is of course fresh oil. I ran about 6500 miles on synthetic I think I will make it 5K next time. It does burn a little oil. Up to a quart between oil changes it appears. I have never noticed any difference no matter what brand of oil I used or whatever weight.
I just do synthetic and change twice a year, pretty much when I feel like it, I don't even write it down anymore.
Mental note: Do a tuneup when the weather is nice. Change O2 sensor. Maybe take it somewhere to flush the tranny with synthetic. 4L80 is heavy duty tranny with 206K miles. Not sure if the fluid is original or not.
