ELIMINATION OF ZINC FROM MOTOR OIL Over the past several years motor oil manufacturers have been slowly eliminating zinc (zinc-diakyl-dithio-phosphate) from motor oil. This has been the primary extreme pressure ingredient in motor oil for over 70 years. Newer cars all have rollers and do not require it. Zinc negatively affects catalytic converters, which is why it is being eliminated. For more information about zinc and motor oil, click here to read the Mustang Monthly article. A PDF version of the article may be downloaded by clicking here. ZINC TREATMENTS To protect your flat lifters and camshaft in older Mustangs, many experts recommend using a zinc additive when changing your oil. "ZDDPlus" is one additive which can be used to put the zinc back in your motor oil. It is available from National Parts Depot and other parts warehouses. ETHANOL IN GASOLINE As many of you may know, ethanol is in virtually all gasoline now sold in Florida. Ethanol and rubber don't like each other. Rubber is found in various places in the fuel system of your older car, such as, gaskets and hoses. Ethanol also absorbs water, which can cause rust in your fuel system. There are a few local places where ethanol free gasoline can be found, most are marinas:
Other locations may be found on www.pure-gas.org. ETHANOL TREATMENTS There is a new product on the market which claims to counteract the effects of ethanol. It's called Ethanol Rx and manufactured by Sentry Fuel Treatments. Unfortunately it doesn't seem to be sold in south Florida. It may be ordered at http://www.sentrytreatments.com and is $44.95/64 oz. plus $5 shipping. They recommend 1-2% solution. At 1% one bottle will treat 50 gallons of gasoline, which is about 50 cents/gallon.
