Good product, works for OEM oil plug and any other plug that is M8-M12
I happened to have stripped the aluminum transmission drain pan on my 04 Tacoma and had to tap the next size up (M12). The washers I got from the parts store were causing a fairly significant leak so I bought these crush washers online, I was not sure if this would work as many people on here say that these washers will ONLY fit the oil drain plug so when they worked I did not expect them to work so well, not a single drop after a week of hard driving. These are good washers and will make a liquid tight seal anywhere. I would use these washers as long as the inner diameter of your bolt matches the diameter on the washers.

Fits my 02' Porsche 986 2.7L
No leaks! Washer quality is a 10/10, softness is decent, ease of installation is a 10/10, thickness is 10/10, and looks are great!

Ideal factory replacement but half arrived unusable
I bought this to perform an oil change on my 2016 Mercedes S550 with a 4.7 liter V8 (M278 engine). When I compared it to the OEM Mercedes part, it matched in every way. My only disappointment is that half of the washers were slightly bent and won't be usable against the machined sealing surface of oil pan. Granted, this is still a better value than the cost of the OEM Mercedes copper washer.

I love these orings. They just give me the extra confidence of my seal. I use it on my 2012 toyota camry xs when I change the oil.

fully compatible with my W210 and S211 and SLK R171 six cylinder mercedes. Cooper washers that crush and form a good seal.
