16 fuel system cleaners entered the tournament. It’s down to two — Redline SI-1 vs Techron Concentrate Plus.
Before I crown a champion I did something most people skip. I put a borescope camera inside two real working delivery vehicles — a 2001 Ford Ranger and a 2000 Jeep Grand Cherokee — both over 200,000 miles, never treated once in 25 years.
Then I put a scanner on both engines and captured the data before a single drop went in.
This is what real testing looks like.
Which one do you think wins?

Omg plus 20 years of use and the piston top looks clean, you should see a combustion chamber from 3 years in Mexico, the carbon buildup is crazy.
