Drain plug o-ring seal
I'm about to do my first oil change at 5,000 miles after tracking the car. The owner's manual says "Inspect the drain plug O-ring seal and replace if it is damaged." There is no part number and no indication of what size or type of o-ring you would use to replace the failed one. I bought a spare drain plug ($29) just in case, but does anyone know how I could get a few of the correct o-rings so I don't have to worry about doing that again? (As you can tell, I'm not a very good mechanic, but I do like to change the oil in my cars.)
Thanks for your help!

Some smart person on here will probably figure out the dimensions of the o-ring and what type of oil resistant materal it is made of. Then you can go to someplace like McMaster-Carr.com and buy a bag of 100 for probably less that $20. I did that when I owned a Harley.

I did that when I needed "0" rings for another project. I purchase an assortment kit for both standard and metric automotive "0" rings that resist oil, hydraulic fluid and water.
I changed the oil on the C8, but the "0" ring on the plug was fine and just reused it. Good to have a set of backup "0" rings if needed.

So there are two different plugs with different "O" ring sizes? I only have one drain plug part number #12695699 if this is correct

Not doubt the GM "O" ring at the end is adequate but if you wanted to buy a better material, Viton would be the choice. Used that material on my Corvair pushrod tubes as the cheap OEM "O" rings would harden and leak! Measure carefully and buy several. However not worth messing around as $2.47 pretty cheap! Shipping will cost far more!
