Specs such as CFM, PSI and torque are the manufacturer’s ratings as listed, collected 12 November 2026. Where a listing contradicts itself, both figures are shown.

How the scores work

Each oil earns a Shop Score on performance, build, value, safety and warranty, with the weights published on the How We Pick page. None states a UL, ETL or CSA listing, so all score zero on safety, and none states a warranty term.

Shop Scores range from a low of 9.2 to a high of 9.8, with each tool positioned by its weighted points proportionally, and more points always yields a higher score. Only powered tools, or tools with stated safety features, get safety points. Everything else is rated out of 90.

What the listings tell you

5 hydraulic oil listings were read for this roundup. Only 1 stated an oxidation stability figure in hours, and 2 stated a 5-gallon size. None stated a warranty term or a safety listing. All 5 stated anti-wear additives.

Buying guide: choosing the best hydraulic jack oil with anti-wear additives

Grade: AW 32 or AW 46

Grade is the first choice here. The Mag 1, Hapco and STARFIRE AW32 oils are AW 32, while the Cam2 and STARFIRE AW46 oils are AW 46. Check the jack manual for the grade it calls for, and match the oil to it: the listings state the grade, not which jack takes which.

Size

Size runs from 1 quart to 5 gallons here. The Hapco oil comes in a 1-quart bottle, for small top-ups. The Mag 1 and Cam2 oils come in 1-gallon containers. The STARFIRE AW32 and STARFIRE AW46 oils come in 5-gallon sizes, for fleets, mobile equipment and industrial machines.

Anti-wear additives

All 5 oils state anti-wear additives. The Mag 1 oil adds FMX Technology, and states the additives help reduce friction, minimize component wear and extend equipment life. The Hapco oil states its additives help reduce metal-to-metal contact. The STARFIRE oils state their additives protect against metal contact and extend the life of hydraulic pumps, valves and cylinders.

Foam and air control

Foam in the oil makes the jack feel spongy. The Hapco, STARFIRE AW32, STARFIRE AW46 and Cam2 oils state anti-foam additives or foam control. The Mag 1 listing states the oil is designed to separate air and water and improve filtration performance, with no anti-foam claim stated.

Rust and corrosion

All 5 oils state rust, oxidation or corrosion protection in some form. The Hapco oil states anti-rust and oxidation resistance. The STARFIRE oils state rust, oxidation and corrosion defense with premium inhibitors. The Cam2 oil states rust, oxidation and corrosion inhibitors. The Mag 1 oil states corrosion protection and varnish control.

Garage Fit Check

• Check the grade first: AW 32 on the Mag 1, Hapco and STARFIRE AW32; AW 46 on the Cam2 and STARFIRE AW46.
• Check the size: 1 quart on the Hapco, 1 gallon on the Mag 1 and Cam2, 5 gallons on both STARFIRE oils.
• Check the container weight: 38.0 lb on the STARFIRE AW46, 2.0 lb on the Hapco.
• No power source is involved: oil, a funnel and a rag are all the job needs.
• Check the oxidation stability: 5,000 hours stated on the Mag 1, and no figure stated on the other 4.
