Case 48 Bottles Russo Synthetic Blend 2 Cycle Motor Oil 5.2 Oz 50:1 Mix 2 Gallon Compatible with Echo Stihl Husqvarna

What It Is

This is a pre-measured 5.2 oz bottle of Case 48 Bottles Russo synthetic blend 2-cycle oil, designed for mixing at a 50:1 ratio with one gallon of gasoline. It’s intended for air-cooled 2-stroke engines in handheld outdoor power equipment like trimmers, chainsaws, leaf blowers, and hedge trimmers.

Fitment & Compatibility

• Oil type: Synthetic blend 2-cycle oil (API TC, JASO FD, ISO-L-EGD rated). Compatible with most brands including Echo, Stihl, Husqvarna, Poulan, and Ryobi.
• Mix ratio: 50:1 (2.6 oz per gallon). Do not use in engines requiring 40:1 or 32:1 unless you adjust the mix—this bottle is pre-measured for exactly 1 gallon at 50:1.
• Volume: 5.2 oz bottle treats 2 gallons of gas. If your machine takes a different fuel/oil ratio, you’ll need to measure separately.
• Not for: 4-stroke engines, diesel engines, or any equipment requiring non-synthetic oil.

Key Things to Know

• Quality: Synthetic blend offers better protection and less smoke than conventional 2-cycle oil, but it’s not full synthetic—expect slightly more carbon buildup over time.
• Installation difficulty: Trivial. Just pour the entire bottle into 1 gallon of fresh unleaded gasoline (87 octane or higher), shake well, and use immediately. No tools needed.
• Common gotcha: The bottle is marked for 2 gallons at 50:1, but it’s actually 5.2 oz—enough for 2 gallons. If you only mix 1 gallon, you’ll use half the bottle. Do not dump the whole bottle into 1 gallon unless you want a 25:1 mix (too rich, leads to fouled plugs and smoke).
• Shelf life: Unopened, 3-5 years. Once mixed with gas, use within 30 days or add fuel stabilizer.

Should You Buy It

Buy this if you need a bulk pack (48 bottles) of reliable 50:1 synthetic blend oil for multiple machines and want the convenience of pre-measured bottles for quick mixing. It’s a solid value for pros or heavy users, but if you only need a few bottles or prefer full synthetic for less carbon, look elsewhere.
