Does anyone remember some of the "fuel saving" items from the oil crisis in the 70s?
I recall one being water jacket with the fuel line running through it. The water jacket was connected to one of the heater hoses. it was supposed to "expand" the gasoline for better mileage. I never tried it but I would think it would cause vapor lock in hot weather.
The other I remember is the "catalyst" in the intake. It went under the carb and looked like a piece of window screen.

Road Test Magazine was real big on these and apparently they actually DID help mileage somewhat.

Oh, yeah, injecting some water into the fuel mixture (well, at least on older cars) does improve combustion....I presume this is why cars run a bit better on rainy days? I am not sure about other side effects, or if the complexity of regulating it is really worth the trouble.
Worth talking about though, if someone has done more research on it.

Edelbrock sold what I think was a fairly sophisticated water injection system. Not just a jug of water with a hose to the carburetor. It actually had two adjusting screws although I can't remember what they adjusted. Maybe one was for the 50 hp increase and the other was for the 100 hp increase.
Mixing alcohol with the water was supposed to be the hot set-up. I think there's something to it, especially if you're trying to run a carboned-up high compression musclecar on 91 octane. More appealing than retarding the timing.
The idea is that it prevents combustion from happening too quickly. Instead of a quick uncontrolled bang you get a flame front that moves from the plug outward the way the guy who designed the combustion chamber intended. Something like that...
#102 of 107 Franz oil filters
Jul 26, 2001 (8:19 am)
I have a new 01 Excursion with the Diesel. Been reading posts on Ford Diesel.com about by-pass filters. Went threw boxes of wonderfull things to good to 86 and found two compleat Franz filters. Took one of them bought new hoses and now have a by-pass filter. Oil had about 2500 miles and was showing color (soot). After 100 miles it looked almost fresh. I plan to do regular 5k oil and filter changes for warrantee purposes but now feel better knowing it will be clean between changes. Big problem was finding paper with the right inside hole diameter. Wall-mart has it in single rolls from Scott, 1k single sheets $.57 a roll (cheap for a filter) . you can find these filters at swap meets for about $5-$15 (seen them). Never used the Franz paper back in the 60's so it was not a concern. I had this filter on my 65 GTO, pulled a valve cover off at 95k miles, you could eat out of it, no varnish or sluge. Franz was not snake oil. The normal spin on filter will pass particulates smaller then 10-15 microns, the Franz 2-4 microns. I use KN filters they rate there's at 10 microns. my $.02 cliffsurfs
#103 of 107 Oil changes on a diesel;

Had a friend that used to drive over the road for a large trucking company. He told me that when a new truck came in..Cummings diesel engine, that it was started and was never turned off and never had an oil change... oil was added as needed, but the engine was warranties for one million miles from the manufacturer I used to drive a car, back in the 50s and 60s. over 70,000 miles a year without interstate highways and do not remember ever changing oil.. just added as needed... and also do not remember having any problems with the cars.(traded every year) Any body want to buy an old can of Marvel Mystery Oil?

I'm afraid you won't have "clean oil" with a diesel engine. Oil in a diesel engine looks dirty after about five minutes of running. So don't expect to see that. This doesn't mean anything is wrong. You can't tell anything about the condition of your oil from just looking at it. Dirty oil can be in great shape, and clean oil can be broken down.
#106 of 107 suggestion for those messy cartridge filters
Dec 26, 2001 (2:09 pm)
If the by-pass or cartridge filter has a top mounted cover, shut the engine off and let it drain for 10 or 15 minutes then remove the lid, place a plastic bag over the filter and remove the cartridge with the bag, saves a lot of mess!
#107 of 107 Oil Additives...

So, the oil is clean, but what about the depleted additives? It's quite a complex mixture.
