RedMax 580357203 OEM MaxLife 2-Cycle Oil 6.4oz 50:1 2.5 Gallon Mix, Case of 48

What It Is

This is RedMark’s OEM 50:1 pre-mix 2-cycle oil, designed for their handheld equipment (trimmers, blowers, chainsaws). Each 6.4oz bottle treats 2.5 gallons of gas, and this case of 48 is bulk supply for commercial or heavy-use operators.

Fitment & Compatibility

• Engine type: Only for air-cooled 2-cycle engines requiring 50:1 ratio. Not for 4-cycle or 40:1/32:1 mix engines.
• Brand fitment: RedMax OEM, but works in any brand (Stihl, Husqvarna, Echo, etc.) that calls for 50:1 mix.
• Check before buying: Verify your equipment’s manual for oil ratio (50:1 = 2.6oz per gallon). This oil is pre-measured for 2.5 gallons—do not use one bottle for less than 2.5 gallons unless you measure properly.
• Storage: Case of 48 is heavy (approx. 19 lbs). Ensure you have space and will use within 2-3 years (unopened shelf life).

Key Things to Know

• Quality: RedMax MaxLife is a synthetic blend with fuel stabilizers, reducing varnish and extending mixed fuel shelf life to 2+ years (unopened).
• Installation difficulty: Trivial—just pour one bottle into 2.5 gallons of fresh unleaded gas (87 octane minimum, no ethanol preferred).
• Common gotcha: This is the 6.4oz bottle, not the 2.6oz single-gallon size. If you only mix 1 gallon at a time, you’ll need to measure 2.6oz per gallon. Don’t dump the whole bottle into 1 gallon—that’s 50:1 mix at 2.5x concentration.
• Bulk value: At $0.48 per mix (2.5 gallons), it’s cheaper per use than buying individual bottles, but only if you go through it.

Should You Buy It

If you run 3+ RedMax 2-cycle tools regularly or mix fuel in 5-gallon batches, this case saves money and ensures consistent OEM quality. For occasional use or single-tool owners, buy the 6.4oz single bottle instead.
