RedMax 598817703 OEM Maxpro 2-Cycle Engine Oil 6.4oz 2.5 Gallon Mix (6 Pack)

What It Is

This is RedMax’s OEM Maxpro 2-cycle engine oil, pre-measured in 6.4-ounce bottles (six-pack) designed to mix with 2.5 gallons of unleaded gasoline at a 50:1 ratio. It’s formulated for RedMax handheld outdoor power equipment (trimmers, blowers, chainsaws, hedge trimmers) and other air-cooled 2-cycle engines requiring high-quality, low-smoke synthetic blend oil.

Fitment & Compatibility

• Engine type: For 2-cycle (2-stroke) air-cooled engines only. Not for 4-stroke or diesel engines.
• Mix ratio: 50:1 (2.6 fl oz per gallon). Each 6.4 oz bottle treats exactly 2.5 gallons of gas. Do not use in engines requiring 40:1 or other ratios unless you recalculate.
• Brand fit: Designed for RedMax equipment, but compatible with any 2-cycle tool that calls for a 50:1 mix (check your owner’s manual). Avoid using in older engines originally spec’d for 32:1 or 40:1 without verifying.
• OEM vs aftermarket: This is genuine RedMax OEM oil. Aftermarket alternatives (e.g., Echo, Stihl, Husqvarna) may use different formulas—stick with OEM if under warranty or for consistent performance.
• Bottle size: 6.4 oz each. Confirm your gas can capacity is 2.5 gallons per bottle to avoid over- or under-mixing.

Key Things to Know

• Quality: ISO-L-EGD and JASO FD certified—exceeds basic API TC standards. Low smoke, high lubricity, and helps reduce carbon buildup.
• Installation difficulty: Trivial—just pour one full bottle into 2.5 gallons of unleaded gas and shake. No measuring needed.
• Common gotchas: Do not mix more than one bottle per 2.5 gallons; over-oiling causes smoke and fouled plugs. Store in a cool, dry place away from direct sunlight. The small bottles are single-use—resealing isn’t practical.
• Shelf life: Unopened, lasts about 2-3 years if stored properly. Once mixed with gas, use within 30 days.

Should You Buy It

Buy this if you own RedMax 2-cycle equipment or any 50:1 air-cooled engine and want a no-measure, OEM-spec oil that’s reliable and simple to use. It’s overkill for occasional users who can buy a single bottle, but the six-pack saves money per mix and ensures you always have the right ratio on hand.
