Used Stabil in my mopars for over 25 years - no problems BUT...

Always made sure I mixed with a full tank before storage - noting the mixing guidelines on the bottle instructions
Always made sure I burned up almost all of that tank in the spring before adding new gas

My brother on the other hand....

Kept mixing Stabil in his 4-wheeler every fall - until it wouldn't start
The shop drained the gas and it was a red gooey mess - he never burned through the entire tank and kept adding Stabil for years until it there was way too much in the "mix"
