## Description

Lucas Oil Deep Clean Fuel System Cleaner, 5.25 Ounce (10669)

Review: Cheap way to get PEA - I think redline is a better value and it’s worth it to pony up the extra $5-$6, but this a great product. Use additives with PEA once every few thousand miles(preferably before oil changes), or add a bit at every fill up, especially if you don’t use good gas
Review: Gas cleaner & injector cleaner - Great product works good 👍👍😊
