Anybody truly interested in subjects like motor oil, oil filters, oil additives, and stuff like that will keep coming back here. This is still the best website on the internet that I know of for discussions on subjects like these.
You have to realize there are now something like 16,000 members here and who knows how many people who visit but don't post. When I became a member here there were only a little over 1000 members. The people who post here range all the way from engineers, chemists, oil analysis people, to people who probably don't even change their own oil. Some people here have intricate knowledge of motor oils and some know only myths and fables. Once a site has 16,000 members you have to expect that.
There are times when it does seem like the discussions will start getting stale but then something will happen to change all of that. Just one example was the news about Mobil 1 oil apparently undergoing a formulation change.
I never would have tried Auto-RX of even heard of Auto-RX if it were not for this website. Auto-RX seemed to stop a seal leak in a car I owned in the past.
There are a few websites I visit on a regular basis. There are some photography websites I visit often. I visit this website for information on car/truck maintenance.
