While you may be tempted to think it is snake oil, my fuel system is squeaky clean, I have virtually no carbon fouling, no corrosion and I am still running on the original fuel pump and injectors in my Stage 1, 25 year old Jetta VR6 and have zero fuel leaks. Fuel filters last longer and it takes much longer for the fuel to start losing octane. Helps maximize power and fuel economy. Noticed a difference to both when I started using the fuel treatment about a decade ago. I also use it in my motorcycles, garden equipment and my 2 stroke powered sport plane, where I also noticed a reduction in carbon fouling, increase in power and reduced fuel burn rate. Sta-Bil + fully synthetic 2 stroke oil is a power combo for getting the most out of any 2 stroke motor. Worries about fouling and seizing become a thing of the past. Longevity goes up dramatically. There is a noticeable increase in power. I calculated that my 65HP motor on my plane makes around 75HP at takeoff power with this combo. That's a 15% increase over standard oil and no Sta-Bil, nothing to scoff at. I have verified multiple times it does indeed keep fuel good for a year. I don't use the Storage version anymore because the in season is good enough for me since I live in the desert and don't need the extra corrosion inhibitors. But if you live somewhere humid and, especially if you live near the ocean, you should use the Storage version for anything that isn't going to run for more than 3 months. Keep in mind the storage product doesn't just protect the fuel system. It also helps to protect your cylinders, valves, rings and exhaust system internally by depositing persistent corrosion inhibitors and has way more of the stuff than the in season. This is why you always want to drive the vehicle a bit after you put the treatment in, before you put it in storage. Plugging the intake and exhaust will help the corrosion inhibitors persist longer. Best of all, Sta-bil products are very affordable. Review: All good, long time user here - I have been using STA-BiL for almost 2 decades, I always put a little bit more to treat the gas, no issue with gas that I got in the fall, and using now in late spring. I usually don't use gas longer than 6 months — old gas go into my car. No issue with clogged carburetor in my snowblower, lawnmower, hedger and string trimer. i empty the tank as much as i can for the snowblower and don't fire it up till a year later. No rust in the gas tank either. Good insurance to have against needless repairs and tinkering. ## Features - FUEL SYSTEM CLEANER: Cleanses the entire fuel system, including fuel injectors, lines, & fuel pumps, this formula removes water, gum, & varnish, ensuring optimal performance & longevity of your fuel system while preventing corrosion. - CORROSION PROTECTION: Industry-leading rust and corrosion protection for all internal fuel system parts. - MPG BOOSTER: Designed to optimize fuel performance which contributes to enhanced gas mileage & improved engine power.

So in 2026 we’re fighting a losing battle with fuel system deposits and all kinds of issues with ethanol gasoline. “Top tier” fuel stations like shell and chevron help, but it’s impractical to go to top tier stations 100% of the time. That’s why I like this stuff so much. I always buy the largest bottle of this stuff, and I add 5oz on an empty tank to my truck, 4oz if I fill up on a 1/4 tank. That means the large 32oz bottle is good to fill my pickup trucks gas tank 6-8 times with this stuff. So for about $15, I get 6-8 tanks of gas worth of a strong PEA fuel system cleaner, that’s an incredible value. I just leave it in my trucks toolbox and always add the 4-5oz at the gas station before I fill up, it’s like muscle memory now. I personally prefer this fuel system cleaner procedure over the much more aggressive cleaners you empty an entire bottle of every oil change. This is a much more gradual (yet still effective) process that you add every fuel tank. This is a fantastic proactive maintenance item that I highly recommend. ## Frequently Bought Together - STA-BIL In-Season Protection Fuel System Treatment | Full Protection Fuel System Cleaner, Injector Cleaner, Increases MPG, Prevents Corrosion, 32oz (6 Pack) - STA-BIL Storage Fuel Stabilizer | Keeps Fuel Fresh for 24 Months, Prevents Corrosion, Gasoline Treatment Fuel Additive that Protects Fuel System, Gas Stabilizer for Fuel Storage, 32 oz. - Fuel Stabilizer, 1 Gallon --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/11746800-in-season-fuel-system-treatment-and-injector-cleaner-32-oz](https://www.desertcart.us/products/11746800-in-season-fuel-system-treatment-and-injector-cleaner-32-oz) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-10*
