Genuine Ariens 4-cycle SAE 10W40 Engine Oil 32 oz Bottle OEM 70724000

What It Is

This is a 32 oz bottle of Genuine Ariens 4-cycle SAE 10W40 engine oil (OEM 70724000), formulated specifically for air-cooled small engines found in Ariens lawn tractors, zero-turn mowers, and snow blowers. It meets API service classification SL or higher.

Fitment & Compatibility

• Check your engine manual – This oil is designed for Ariens engines that specify SAE 10W40 viscosity, typically used in warmer operating temperatures (above 32°F).
• Model match – Works with most Ariens 4-cycle engines, including those on select S-Series, Classic, and Zoom mowers, plus many snow blower models.
• OEM vs aftermarket – This is genuine Ariens oil, not a generic substitute. If you have an Ariens engine, it’s a direct fit. For non-Ariens engines, verify the oil spec (10W40) and API rating.
• Measurements – 32 oz bottle; typical small engines hold 18–24 oz, so one bottle usually covers one oil change. Check your engine’s oil capacity (often printed on the dipstick or in the manual).

Key Things to Know

• High-quality formulation – Contains additives for thermal stability, anti-wear, and deposit control, which helps extend engine life in hot-running mowers.
• Easy DIY – No special tools; just warm up the engine, drain the old oil, and refill. A funnel and oil drain pan are all you need.
• Common gotcha – Do not use 10W40 in cold weather (below 32°F) – it becomes too thick for easy starting. For winter use on snow blowers, switch to SAE 5W30 or 0W40 as recommended.
• Storage – Keep sealed and at room temperature; avoid freezing, as viscosity can temporarily thicken.

Should You Buy It

If you own an Ariens 4-cycle mower or snow blower that calls for 10W40 and you’re doing a routine oil change, this is the correct, hassle-free OEM choice. It’s a fair price for genuine quality, though you can save a few dollars with a generic 10W40 if you don’t mind verifying the API rating. Best for owners who want guaranteed compatibility and peace of mind.
