(The oil which sprayed out of James Bond's 1963 Aston Martin DB5 can be put to better use refined and in your gas tank; read below for the easiest way to save $$$ at the pump).

After reading this post, you’ll be able to save a minimum of 25 cents, and in many cases a lot more, not just per tankful, but per gallon of gasoline.

And you don’t have to call some 800 number for “magic pills” or order a “secret report the government doesn’t want you to see” about a 100-mile per gallon carburetor; this “trick” is free.

Unfortunately, diesel fuel buyers can’t benefit from this ploy.

Which, to put it simply, is: Just say “pass” on the high-test gasoline and stick with the lowest grade of gas your car or truck can guzzle without getting ill.

The truth is that very few unmodified cars will run best only on high octane. Most every car and truck sold  in the US will run just fine on “regular,” usually 87 octane, and mid-grade gasoline, usually 89 octane. The highest grade gas sold in California is 91 octane.

My long-time friend, John Dinkel, author of the “Road & Track Illustrated Automotive Dictionary,” offers an authoritative word on the subject: “If a carmaker recommends gasoline with a minimum RON (a method of measuring a fuel’s anti-knock abilities) of 91, fuel from a pump with a rating of 87 or higher can be used”.
