Used to roll my eyes at fuel additives, thought it was all snake oil for gullible people. Then my buddy with an old diesel truck swore by this injector cleaner from the auto parts store. I tried it as a last resort before some expensive repairs. Honestly, the engine smoothed right out and my mileage ticked up a solid two miles per gallon. Changed my whole view on that stuff actually works.

Using an old horseshoe like that is smart. I keep a few worn ones in my truck for demos. Let people feel the weight. Show them where the nails go. Point out the wear patterns. It clicks for them real quick.

Weren't the Apollo cameras special Hasselblads, @blairtaylor?
