Every few years I post up the Oil Filter Study. Mostly it is a way to convince you to buy better filters for your Rovers. In looking for a totally unrelated email I found an email where I sent the Oil Filter link to a friend. I thought it had been long enough since the last post that I should probably post it again.
The good news is the study is still online. The better news is I have a new link, due to the study moving to a new page.
Thanks for reading and Happy Rovering.
