Ok I just went to Ralph Wood's website and was reading the content...I am a bit confused...

You mean he sells filters that you put a roll of TP in to filter your engine oil? :blink:

Man I thought I knew a lot about cars....that is a first to me. Not saying anything bad towards him or the filters - I just never heard that before.

Wow...ummm I've never seen or heard of anything like that. :unsure:

I hear that every roll of toliet paper you have under your hood adds something like 15HP each.

Not sure about his application but that idea has been around since at least 1968 and maybe even earlier. I knew a guy who had one on a Ford Fairlane overseas where I was stationed at the time. The actual filtering ability and performance at least back then was very questionable. This might be different..........of course, maybe Charmin is the answer and was not availble back then :)
