Packard Forum Index » Post-War (1946-54)

In 1951 and 52 Mayfairs were considered to be 250's.
I never heard the term Mayfair until several years after we bought the '52. We always referred to it as a "250".
Probably picked up that terminology from the dealer.

Although it states 1952 Packard "250" Mayfair on the original envelope that the car title and bill of sale were delivered to my parents. I'll have to post that envelope.

Saw this link, says it can increase your MPG, would any of you consider using such a device ? Or never.

Gary, I think your mileage would be better if you just sent me the money. Those are just automotive quackery.

This device is even more preposterous than fuel additives which claim improved performance. I support R&D at an Army ground vehicle research facility, and I have lost count of the number of companies that have approached us offering their performance-enhancing products and claiming significant improvements in horsepower and fuel efficiency simply by pouring 8 oz of their snake oil into a vehicle's fuel tank.

The U.S. Army recognizes the potential of additives to impart desired qualities to improve products we use. This is based on the fact that additives are routinely used in lubricants and fuels as cetane improvers, anti-oxidants,
and anti-wear agents. However, the blending of additives in products is a careful balancing act to ensure the product performs as desired and doesn't adversely affect the
benefits of other properties, or reduce the system reliability in other areas. Tossing an additive into an already formulated product can throw off this balance and needs to be verified before implementing. Unfortunately,
there is no single quick and easy test to verify whether the additive has the claimed benefits or if there are any adverse effects elsewhere. When we have asked these companies selling these additives for their industry-accepted data/reports supporting their claims, they NEVER seem to be able to cough them up. Rather, they rely on testimonials or very questionable science. Then they have the audacity to suggest that the Army pay for testing them!

I should note that the EPA requires any additive intended to be used as a fuel additive to be registered with them. This registration is needed to verify the additive product only contains chemicals already present in the fuel. EPA registration is not a validation of the improvements or benefits claimed on the product.

Can you tell I have something against additives?

I remember in the 50's that we could buy a gadget that went inline with the coil wire to "supercharge the spark for better mileage" and then a turbo wheel which was a little tiny propeller mounted under the carb that spun with air flow to "super atomize the gas and precharge the cylinders" for better mileage and more power--until the tiny rivet holding the propeller wore off, letting it charge the cylinders in another way.

So, having said that, magnets were also used then and this is the type magnet we use here.http://www.xump.com/science/3inAlnicoCowMagnet.cfm?SID=12 . For ?55 you can buy considerably more of these--enough to place them every few inches along the fuel line. Wrap in green duct tape instead of the green plastic, and by the time the fuel gets to the carb, it will be self replicating and you will never have to fill up again.

Hey, that sounds good...Maybe we should go in business. Might even get a quantity discount on the magnets.

Another gimmick I recall was the "Hydro-catalyst", an alleged platinum screen and gasket that replaced the gasket beneath the carburetor. We had a couple of suckers at work who bought these things, (a) it wasn't platinum, and (b) it didn't increase gas mileage - much to almost no one's surprise.

P.T. Barnum was right..."There's a sucker born every minute."

I've no personal experience with it, but if Bill Hirsch is selling it, I doubt very much that it's a gimmick, Bill's reputation is excellent and I'm sure the product has some merit. But on the other hand don't expect miracles in a can or jar.

The paint is based on reacting with iron oxide to stabilize it
