Ariens SAE 0W-30 Extreme Cold Engine Oil Quart 00077900 and Fuel Treatment

What It Is

This is a quart of Ariens SAE 0W-30 extreme cold engine oil (part #00077900) bundled with a fuel treatment additive. Designed for Ariens lawn tractors, zero-turn mowers, and snow throwers operating in frigid conditions (below 0°F / -18°C).

Fitment & Compatibility

• OEM vs aftermarket: This is genuine Ariens oil, not a generic substitute. Use only in Ariens engines that specify SAE 0W-30 viscosity (check your owner’s manual).
• Engine types: Compatible with Ariens air-cooled engines (e.g., Briggs & Stratton, Kawasaki, Kohler) that accept 0W-30; not for engines requiring 10W-30 or 5W-30.
• Fuel treatment: Works with any gasoline engine (up to 5 gallons of fuel). Treats fuel stabilizer and winter storage.
• Check before buying: Confirm your Ariens model’s oil capacity (typically 20–48 oz) – this quart covers most single-cylinder engines but may need two for V-twins. Verify your engine’s cold-weather oil spec in the manual.

Key Things to Know

• Extreme cold performance: 0W-30 flows better than 5W-30 below -20°F, reducing startup wear. Overkill for mild winters – use 5W-30 above 0°F.
• Installation difficulty: Easy – drain old oil, replace filter (if equipped), pour in full quart. No special tools needed.
• Fuel treatment: Add entire bottle to a full tank of fresh gas before storage. It stabilizes fuel for up to 12 months but won’t fix stale gas.
• Gotcha: This oil is not for 4-stroke snow blowers with separate oil sumps – check your model’s dipstick location. Also, don’t mix with other viscosities.

Should You Buy It

Buy this if you operate an Ariens machine (mower or snow thrower) in consistently subzero winters and want OEM-spec protection. Skip it for mild climates or engines that don’t call for 0W-30 – a cheaper 5W-30 will work fine. The fuel treatment is a decent bonus for winterizing, but you can buy stabilizer separately for less.
