Which is peanuts compared to the economic cost of distributing lead into everyone's lungs and waterways... But somehow it's the 85 cents a gallon everyone's worried about, not the tens of billions of dollars...

As the comments note, however, unleaded gas will not cause lead deposits in the engine and can therefore reduce maintenance required and extend maintenance intervals.

  This is unlikely to be a major factor for aircraft engines, which need to be serviced regularly anyway (long before lead deposits would force it.)

  In my experience, "lead deposits" are basically an issue caused by running excessively rich mixture, usually on the ground, and show up as spark plug fouling with engine roughness and reduced RPMs. The fix is just to vaporize the deposits by running the engine at leaner and at a high power setting. I understand that you can also end up with exhaust valve deposits, but that's not something I've seen personally. Aviation engines (especially those used for training, which is a large proportion of the piston fleet) have incredibly short inspection intervals in any case.

What's the current price per gallon?
- DaiPlusPlus 5y ago
  According to http://www.100ll.com/ http://www.100ll.com/ - about $6.00 to $6.70 at retail. Looking at my own local airports ( e.g. http://www.100ll.com/showfbo.php?HashID=d0f7e0afbdcf9b9a7cdea686d5a7c8e5 http://www.100ll.com/showfbo.php?HashID=d0f7e0afbdcf9b9a7cde... ) the price goes higher to often over $7.00/gal, though that's for "full service" (I don't know what that means, though).

    Full-service just means it's dispensed by an employee rather than by the pilot. (The practical implication is "you can buy fuel only when the business selling fuel is open, or pay a call-out fee".) This could be dispensed from a fuel truck (most common for full-serve) or from a pump. Self-service means there's a pump with a credit card and a really long hose, that would look familiar to what you see at an auto filling station.

  You don't want to know. Somewhere between $5-10/gallon. Normal times, $3.50-7/gallon.
