The 300,000-Mile Fuel System Health Sheet

Most fuel system advice online is outdated or trying to sell you a miracle in a bottle.

I run an independent auto parts store. I see what actually works — and what people buy after things go wrong.

This one-page Health Sheet shows you:

• Which fuel additives actually do something — and why

• The real difference between cleaners, lubricants, solvents, and stabilizers

• The truth about octane boosters (and why most people waste money on them)

• A simple fuel system routine designed to help engines reach 300,000 miles

No fluff. No brand worship. Just chemistry, real-world use cases, and guidance you can follow.
