Fuel Stabilizers
Florida ethanol-blend pump gasoline (E10) is the #1 cause of small-engine carburetor and fuel-system failure. Equipment that sits between mowing weekends, generators that wait for hurricane season, and chainsaws that store between storms all need stabilized fuel. AMSOIL Quickshot and Gasoline Stabilizer protect carbs, injectors, and fuel lines.
Cleans gum and varnish from carburetors, injectors, and combustion chambers fouled by ethanol-blend gasoline. Stabilizes fuel for short-term storage and helps prevent ethanol phase separation. Critical for mowers and generators that sit between weekends or hurricane-season events.
Product Codes:
Specifications:
Long-term fuel stabilizer for off-season equipment storage — mowers, generators, snow blowers, chainsaws, and string trimmers. Keeps gasoline fresh up to 12 months and prevents gum and varnish in small-engine carburetors and fuel rails.

Outdoor power equipment lives a brutal life — wide-open-throttle operation, extreme heat, dust, grass clippings, ethanol-blend pump gas, and long sit periods between use. AMSOIL builds a full line of synthetic lubricants engineered for exactly that duty: 4-stroke synthetic small-engine oil for mowers and generators, SABER Professional 2-stroke for chainsaws and trimmers, bar & chain oil, hydrostatic transmission fluid for zero-turn mower drives, UTTO tractor hydraulic for compact tractors, ISO hydraulic oil for log splitters and snow plows, and diesel oil for Kubota, Yanmar, and Mahindra compact tractors and diesel generators.
AMSOIL 5W-30 100% Synthetic Small-Engine Oil (AESQT-EA) covers cold-start service — generators waiting for hurricane season, pressure washers, snow blowers, and any small engine that has to start cold. AMSOIL 10W-30 100% Synthetic Small-Engine Oil (ASEQT-EA) is the most popular small-engine viscosity — Kohler Command, Briggs & Stratton, Kawasaki FR/FX, Honda GX, and Vanguard residential mowers. AMSOIL 10W-40 (ASFQT-EA) steps up film strength for commercial big-block engines (Kawasaki FX, Vanguard 810/993). AMSOIL 15W-50 (SEFQT-EA) is the heaviest viscosity — engineered for severe-duty Florida commercial mowing in sustained 95°F+ ambient temperatures with 8+ hour daily run times.
AMSOIL SABER® Professional 2-Stroke Oil (ATPPK-EA) is engineered to mix at up to 100:1 — far leaner than the typical 50:1 ratio of conventional 2-stroke oils. Cleaner combustion means less smoke, far less spark-arrestor and exhaust-port carbon, and longer chainsaw, trimmer, and blower service life. SABER replaces Stihl HP Ultra, Husqvarna XP, Echo Power Blend, and any other JASO FD / ISO-L-EGD 2-stroke oil. One 8 oz pouch treats 6.25 gallons of fuel at 100:1 — over twice the fuel of a conventional 50:1 oil.
AMSOIL 20W-50 Hydrostatic Transmission Fluid (AHFQT-EA) is engineered for zero-turn mower transmissions — Hydro-Gear ZT-3100/3400/4400, Tuff Torq K46/K57/K58/K72/K92, Parker HTE/HTG, and Sauer-Danfoss. Maintains viscosity under sustained mowing load, reduces foam, and extends pump and motor life. AMSOIL 5W-30 Tractor Hydraulic/Transmission Oil (ATHQT-EA) is a UTTO multi-function fluid for compact tractors — compatible with Kubota Super UDT2, John Deere J20C/J20D, Mahindra Premium UTF, and Massey Ferguson Permatran III specifications.
AMSOIL Signature Series 15W-40 100% Synthetic Max-Duty Diesel Oil (DMEQT-EA) is API CK-4 / SN certified for diesel-powered compact tractors (Kubota L/B/MX, Yanmar, Mahindra, John Deere 1/2/3 series), diesel generators, and diesel skid-steers. Excellent soot dispersancy, oxidation resistance, and protection through extended service intervals. For fleet operations, AMSOIL 15W-40 Commercial-Grade Diesel Oil (SBDF1G-EA) offers fleet-friendly bulk pricing.
AMSOIL ISO 22 100% Synthetic Multi-Viscosity Hydraulic Oil (HVG05-EA) is engineered for cold-temperature hydraulic service — log splitters and snow plows that have to function at sub-freezing temperatures. AMSOIL ISO 32 / 46 / 68 Commercial-Grade Hydraulic Oil (HCG32/46/68TP-EA) covers normal and high-temperature commercial hydraulic systems on industrial and outdoor power equipment.
Florida ethanol-blend pump gasoline (E10) is the #1 cause of small-engine carburetor failure. Equipment that sits between mowing weekends, generators waiting for hurricane season, and chainsaws stored between storms all need stabilized fuel. AMSOIL Quickshot (AQSCN-EA) cleans and stabilizes for short-term storage; AMSOIL Gasoline Stabilizer (ASTCN-EA) protects fuel up to 12 months for off-season storage.
