Husqvarna 593271603 Husqvarna XP+ 2-Stroke Engine Oil, Grey

What It Is

This is Husqvarna’s XP+ 2-stroke engine oil (part #593271603), a high-performance synthetic blend designed for air-cooled, pre-mix engines in handheld equipment like chainsaws, trimmers, and leaf blowers. It’s formulated to reduce exhaust smoke and carbon deposits while protecting at high RPMs.

Fitment & Compatibility

• Engine type: Only for 2-stroke (gas-oil mix) engines—not for 4-stroke or separate-oil-injection systems.
• Mixing ratio: Use 50:1 (2.6 oz per gallon of unleaded gasoline) as recommended by Husqvarna for all XP+ labeled engines. Do not use in older models requiring 40:1 or 32:1 unless specified in your manual.
• OEM vs aftermarket: This is genuine Husqvarna oil; compatible with any brand of 2-stroke engine that calls for a 50:1 mix (e.g., Stihl, Echo, Ryobi), but best for Husqvarna XP-series equipment.
• Measurement check: Bottle is 16.9 fl oz (500 ml)—enough to mix with 6.5 gallons of gas. Verify your equipment’s fuel tank capacity to avoid leftover mix.

Key Things to Know

• Quality: Synthetic blend meets JASO FD and ISO-L-EGD standards, giving superior lubrication and low ash—helps prevent spark plug fouling and exhaust port clogging.
• Installation difficulty: Easy—just pour into a clean gas can, add fuel, and shake. No special tools or steps needed.
• Common gotcha: Do not use in 4-stroke engines or oil-injection systems (e.g., some Husqvarna automix models). Also, mixing more than 50:1 (less oil) can cause engine seizure.
• Storage tip: Once mixed, use within 30 days; the blend separates over time. Store oil bottle tightly sealed in a cool, dry place.

Should You Buy It

Yes, if you own a Husqvarna XP-series 2-stroke tool and want a factory-recommended oil that minimizes smoke and deposits. It’s also fine for other brands using 50:1 mix, but you can save money with generic equivalents if you don’t need OEM-specific protection.
