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

What It Is

This is a quart of Ariens SAE 0W-30 synthetic engine oil, designed specifically for extreme cold weather operation (below 0°F / -18°C). It’s intended for Ariens two-stage snow throwers, zero-turn mowers, and small engines that require 0W-30 viscosity for reliable cold starts and winter storage.

Fitment & Compatibility

• Check your owner’s manual for the recommended oil viscosity and capacity. Ariens snow throwers and some mowers specify 0W-30 for sub-zero use; others may require 5W-30 or 10W-30 for warmer conditions.
• This is the OEM Ariens part (00077900) – not a universal aftermarket oil. It’s formulated for Ariens engines but can be used in other small engines that call for 0W-30 (e.g., Briggs & Stratton, Kohler) as long as the viscosity matches.
• Capacity: Most Ariens snow throwers take around 20–24 oz (0.6–0.7 quarts). A single quart is usually enough for one oil change, but always verify your engine’s specific sump capacity.
• Not for mowers used in warm climates – 0W-30 is too thin for sustained summer operation above 32°F. Use only if your machine’s manual explicitly lists 0W-30 as acceptable.

Key Things to Know

• Synthetic blend – provides better cold-flow properties than conventional oil, reducing wear during frigid starts. It also offers some protection against sludge and deposits.
• Installation difficulty: Easy – just drain the old oil (warm engine helps), replace the drain plug, and refill to the dipstick “full” mark. No special tools needed.
• Common gotcha: Do not mix 0W-30 with a different viscosity. If you’re switching from 5W-30 or 10W-30, drain completely before adding this oil.
• Storage: Keep the quart sealed in a cool, dry place. Once opened, use within one season; oil degrades over time.

Should You Buy It

Buy this if you own an Ariens snow thrower or other small engine that requires 0W-30 and you operate regularly in temperatures below 0°F. It’s a premium synthetic that ensures reliable cold starts and reduces wear. For warmer-weather use or engines not specifying 0W-30, a standard 5W-30 or 10W-30 is more appropriate and cheaper.
