There are dozens and dozens of specialty oils, additives, filters and cleaners on the market.
Always have been. Always will be. Just today someone was hitting all the Toyota
newsgroups with this rediculous post about a new NAPA oil filter:

Hi,
has anyone heard about the new NAPA Spinflow oil
filter. I just bought one for myself recently and it
rocks!. They claim that it will improve the
performance of your car and I can definitely feel the difference. I
guess it's also supposed to prolong the life of your engine due to
better oil filtration but I'll just have to wait and see. It also
costs about the same as a standard Frahm filter so I figured I really
couldn't go wrong. I'm all about passing the word along about a good
product and this product is great. With that said, check out the link
below where I found my info. You will see what I mean.
Thanks!
