    I don't know anything about cars and I am just fortunate to have learned how to drive. My husband falls in the same category. We have been advised many times by (different) gas station attendants to fill our tank with premium instead of the prescribed unleaded gasoline. Their reason is the power that the premium gas could give the engine. In the long run, it is more economical to use premium gas than unleaded gasoline.

    But our apprehension is the complication that might occur. What if the car's engine develops a problem? There's even a sticker in the gas tank that says "unleaded only" so logic tells us to just follow what the sticker says.

    @Corie Henson Geez! Corie, are you telling me that gasoline sold as "premium" there still contains lead? I was under the impression that adding lead to gasoline had been banned worldwide! Only a forum such as this one could communicate facts of most significant value to the mass of thousands of respondents!

    I am grateful you mentioned this. Here in the States we have "regular unleaded" and "Premium unleaded", but the difference lies in compounding of the two: the "Premium" has more Octane blended into it, as well as additional alcohol. Lead contamination of the World's Environment has been shown to be the result, mainly, of "leaded" gasoline, introduced 90 or more years ago. We obviously do not want lead in our air, water, food, anywhere that it might enter our bodies. Lead was also used exceedingly extensively in paint used in homes. That lead has resided in countless millions of homes worldwide, adding to the body burden of lead carried within. Lead is not as serious a poison as Arsenic or other "heavy metals", but should be avoided if possible. Note: Bullets are made of lead. One joker quipped that if the bullet don't kill 'ya, the lead in it will!

    @Frank Sanoica, that's how I understand it - the premium gasoline here has lead content which gives it the power, that is according to the attendant. Maybe that's why the color of the pump's hose is green for the unleaded to mean clean fuel while it is red for the premium gasoline. The premium is slightly expensive than the unleaded gas. But they say that premium gas is marginally cleaner then diesel. Well, diesel is the fuel of big vehicles like buses and trucks and proof is the black smoke in their behind.

    @Corie Henson , you may want to read this link. HERE

    It lists only 6 countries that in 2011 were allowed to sell leaded gas. Your country isn't one of them. :eek: But even those six weren't supposed to be using it by 2013.

    When you get down to the "brass tacks" of it, lead was one of the most expensive constituents in gasoline, the major part of it being hexane, heptane, and octane, all derived from Petroleum. Lead must be mined. Tetra-Ethyl Lead involved a costly manufacturing process before it was ready to be dumped into the gasoline. Worldwide lowering of Intelligence Quotient (IQ) has been attributed to the "leading" of gasoline for 60-70 years.

    Incidentally, "As of June 2016 only Algeria, Yemen, and Iraq continue widespread use of leaded gasoline."
