Just curious about the cause behind the high-speed turnpike driving exception for my own knowledge, and if this means one might want to consider something different for the tank if one was planning a longer trip with more highway miles?

Re:leaded additives/fuel, this is still the #1 thing (in my experience) that men aged 50-70 ask me specifically about. Usually after making some comment about their opinion on the styling and/or putting a V8 and disc brakes in. My replies about the originality and it being fine on pump gas after the rubber/carb rebuild baffles every time! The ladies and younger or older folks always love the car as is.

you need to be above a certain age to have heard the ads from gas companies for how additives made their brand of gas better.

PennyPackard, perhaps this will help your understanding of the relationship between high speed driving and stress on exhaust valves and seats. Sorry, I forget the original source of this graphic.

For more, just Google "valve seat recession" and you'll find an afternoon's worth of reading. Here's a good one to start with: ... -seat-recession-explained
