Primary Retail Channels:
For a quick comparison of where to find specific product types, here's a helpful guide:
| Retail Channel | Product Examples | Key Advantage |
|---|---|---|
| Official Website | JB5100 Super Concentrate, JB10101 Carb Defender | Full product range, official support |
| AutoZone / O'Reilly | Fuel Injector Cleaner, Oil Stabilizer | Immediate in-store pickup |
| Amazon / Walmart | Most popular single bottles | Competitive pricing, fast delivery |
When purchasing, especially from third-party online sellers, it's a good practice to check the product's manufacture date to ensure freshness. Reading user reviews on these platforms can also provide real-world insights into a product's effectiveness for your specific vehicle issue.

I just grab mine at AutoZone. They always have the little bottles of fuel treatment right near the checkout counter. It's perfect for when I'm already there buying oil or a new air filter. If they happen to be out, I'll order it from Amazon and it shows up in a day or two. No need to overcomplicate it.
