So I wanted to share something I have been experimenting with for the past 3 years with great results. Now a lot of you may have heard of people doing this because it's all over the place. Home made Gun oil. Very simple to do. I learned this from a person who has been in airgun competitions for many years. It's simply a mix 20% cvt synthetic transmission oil and 80% synthetic motor oil. Most people use Alphabet org which is good but CVT is just a aft on steroids if you will. Now I don't use it on my seals or caskets although people do but only on all of my sliding, rubbing and moving parts. I use pelgunoil on my co2 and seals. So after all these years of my home made mix I have to say my full and semi bb guns are still working fine with no issues and had them apart and all the parts look like the day I bought them. Just wanted to share hope it helps someone.
