Oil, lubrication, and filters are fascinating. Even more so when you get to do your own maintenance on your own machines. It's the little boy in us who loves knowledge and working with their hands and that feeling of accomplishment.
Honestly, I just like using the best products within reason. I research everything, why not motor oil and filters? Plus the community here is laid back and most of us have been here for years. Intelligent posters enjoy conversing with one another. Most other enthusiast auto forums are too full of knuckleheads for any meaningful research or discussion.. Especially the past few years with social media and smart phones. Every punk is posting on forums from their phone.
