Oregon Chain Markings

[KennyG]

For my Stihl that has a .325 chain with .050 gauge, I see that Oregon stamps the chains with either a "20" or a "95", both with .050 gauge. Can some of our more knowledgeable members explain what the difference is?

Here are a good description of similar chains.

The 20 series

And the 95 series which is considered narrow kerf which is suppose to take less power to use

In Oregon regular like LGX LPX 325. 20 050 and 21 058 and 22 063

95 NK chain.
