i saw this at my local walmart aswell.. im sure its a good product, but then again its probably just the same as the pennzoil fuel system cleaner etc..
try it, it won't stay $3.50 for long. like the Shell V-power it will be $7-8 after the introductory phase is over. or it's being discontinued and it's close out
The only truly effective formulas of fuel system cleaner have large % of PEA detergent in them. This makes them very effective and quick to start cleaning, and most importantly SAFE for your cars fuel system!!!!!!!
Gumout Regane Complete Fuel system cleaner is the only consumer brand that currently has such a large amount of PEA in it.
