Hi,
Your father was right. In 1963 I was working in a full service gas station in California. I checked the oil in an old Cadillac. I said I see you just changed oil. He said something like yes about 100,000 miles ago. He pointed to a Frantz oil cleaner and said if you had one of those and Delo 100 your engine wouldn't wear out and you wouldn't need to change your oil. I found a Frantz dealer and put one on my Rambler American. I was already using Delo 100 30 wt. My oil went from black to clear in a day or so. I was hooked.
When Motor Guard came out in 1966 I signed up as a dealer. Motor Guard learned that to stay in business they had to stop trying to sell filters to people that have been taught that oil is supposed to get dirty. They went to a special element and concentrated on things like vacuum pump oil, ION implantation, plasma etching, low pressure chemical vapor deposition systems, instrumentation, compressed air, etc.
About 15 years ago I was asked what we could do about oil and moisture in the air causing problems with our expensive instrumentation and pneumatic controllers. My wife checked on the Internet and found Motor Guard. That got me employee of the month and employee of the year.
I called Motor Guard about a year ago and told them to send me 12 automotive filters. The secretary said do you mean compressed air for spray painting in a body shop. I finally got the President of the company. He remembered the lube oil filters. I had to toss the polypropylene seals designed for their special elements and install Depont Delrin seals. I had to install an orifice. I am thinking about adding a sintered bronze secondary filter for people that are concerned that paper fibers might get into the oil. I just sent one to Florida with a secondary filter.
The industrial filters are beefed up and have an epoxy coating. Their special elements are similar to what they make coffee filters out of. They work fine but the polyethylene core has a 175 degree F limit. After 40 years of using toilet paper I'm not going to change. I need to find a use for these expensive elements that I am piling up. I can remove the plastic core and install a TP core. The special elements make a wonderful fuel filter.
Gulf Coast down at Gulfport, MS does a lot of military business. The government is using the filters to cut down on waste of natural resources. General Motors has a paper towel filter now that they offer as optional equipment. Some government agencies are requiring the filters installed on delivery. I got an email from a truck dealership in Florida. They said they were submitting a bid to the space program and the filters are required. Toilet paper filters for the hydraulics and cooling system. Paper towel filters for the lube oil and fuel. Toilet paper filters have always been good for a joke or BS story. These days a lot of people are not laughing.
One filter company claims to have an advanced element. I've never seen one. I have seen ratings on them in some military literature. Someone on a boating forum cut open an element. Inside they found a roll of toilet paper. The trick is to find an element that works as good as toilet paper that you can call something else. All of these types of filters will get the job done.
A guy in Minnesota had some Motor Guard's still in the box from a VW repair business he sold 30 years ago. I traded him a M-30 set up for fuel for one of the M-100's. He needed to filter cooking oil to burn in his VW diesel. I needed the instructions. You do what you gotta do.
