I think you missed what I wrote. I worked that engine 10X as hard and didn’t ruin the plugs. Av Gas was fun, but not ideal for cars. It’s the wrong operating environment for the formulation.
20-minutes at WOT with a 14k combined gross rig at 9,000 feet (do the HP reduction for altitude) is a huge difference from only a few minutes accel time with a car varying between 5-6k at a few hundred above sea level.
And that car had been fitted with Chrysler’s transistorized ignition.
It’s the lighter duty work that cooked them.
I haven’t said no one should use it. But you’ll have to fill out the tax forms to do so, and — as it’s simply not ideal as a one to one swap — the question is why.
With others, I’d just use recommended additives.
The other part you missed is that THE QUALITY of today’s gasoline is terrible versus what we had 45-years ago. This has nothing to do with lead or no lead.
The extremely tight controls on these modern marvel engines are why the quality doesn’t matter as much. Good luck running an older engine without a complete redesign. Daily hard service.
Experience with available fuel is where it’s at. Correct storage and additive mixture. Supply of both.
Av-Gas will be highly restricted in the event of a problem.
If that problem presents you with reliability issues (learning curve) using conventional gas, nows the time to get that out of the way.
