Keisha uses Fuel Stabilizer

Panic! occured when my check engine light came on, go a reading on my car which stated my Throttle in my car was dirty, 1)mecahanic told me the whole gas tank would have to be cleaned out ??? another said he'd have to check to see what's wrong (I already knew) and another told me I would have to replace the whole Throttle. But the last mechanic said I could do a treatment myself and the man in AutoZone directed me to what he said was "The Best" on the shelf. Needless to say soon as I gave Henry (that's my car's name) his gas treatment the light cut off no sooner than the gas started flowing. Me being a woman not knowing much about cars learned to shop around but now I know about this great line of products to which I will live by for the life of my car. THANK YOU LUCAS OIL
