From seasonal boaters who return to perfectly running engines after months in storage, to classic car enthusiasts who trust us with their prized possessions, our customers appreciate how STA-BIL eliminates the frustration and expense of fuel-related problems. “I never worry about my equipment starting when I need it most,” is a sentiment we hear repeatedly from homeowners, outdoor enthusiasts, and professional contractors alike.

As someone who maintains multiple vehicles and power equipment for my landscaping business, fuel issues were costing me time and money every season. I was skeptical when a fellow contractor recommended STA-BIL, but decided to give it a try. What a game-changer! My equipment now starts reliably after months of storage, and I’ve noticed improved performance in my daily-use equipment too. The ethanol in today’s fuels was wreaking havoc on my carburetors, but STA-BIL has eliminated those problems completely. It’s become an essential part of my maintenance routine, and the small cost per treatment has paid for itself many times over in prevented repairs and downtime.

I used to dread spring startup for my boat and lawn equipment after winter storage. Despite my best efforts, I’d spend hours troubleshooting fuel issues and often ended up with expensive repair bills. Since discovering STA-BIL Fuel Stabilizer three years ago, those problems are completely gone! Now I just add STA-BIL before storing my equipment, and everything starts right up in spring—first pull, every time. The peace of mind is worth every penny, especially for someone like me who isn’t mechanically inclined. I recommend it to all my neighbors and family members. STA-BIL has saved me countless hours of frustration and hundreds in repair costs!

As a motorcycle enthusiast who treasures weekend rides, nothing was more disappointing than my bike refusing to start after winter storage. Three years in a row, I faced costly carburetor cleanings until my mechanic recommended STA-BIL. What a revelation! Now I add it to my tank before storage, and my Harley fires up perfectly when riding season returns. The peace of mind is incredible, knowing my passion won’t be delayed by fuel issues. STA-BIL has become as essential to my motorcycle maintenance as oil changes—I wouldn’t dream of storing my bike without it!
