Verdict: Choose lithium if the work is general chassis and suspension greasing with a spray can, and a stated temperature range matters. Choose synthetic if the joints see heavy shock loads and wet ground, where the Moly listing states washout resistance and film strength.
Around a property with a mower shed, a trailer, and machines that work through the season, grease is the quiet job that keeps joints moving. The lithium vs synthetic chassis grease choice comes down to what the joint faces: steady chassis work, or heavy shock loads in wet ground. This comparison uses the listings below as concrete examples, with both sides shown.

Who it's for: owners who want a brush-applied grease for hinges, bearings, and garage doors.
Who should skip it: owners who want a spray can, a cartridge, or a listing that names chassis use.
Read the full review
The AstraVox listing states a white lithium grease with a brush for hinges, bearings, gears, and garage doors. The listing states a moisture-resistant barrier against rust, corrosion, and oxidation, and a range from -12°C to 200°C. The listing names automotive, marine, industrial, and household use, but it does not name chassis parts, so it is the weakest chassis example in this set.

What lithium brings
The lithium side here comes in two forms. The WD-40 listing is a white lithium grease spray in a 13.3 OZ can, made for chassis and suspension and heavy equipment. The listing states a working temperature range of 0°F to 300°F, a formula that will not melt, freeze, or run off, and a Smart Straw that sprays 2 ways for precise application or broad coverage. The AstraVox listing is a white lithium grease with a brush, made for hinges, bearings, gears, and garage doors, with a stated range from -12°C to 200°C and a moisture-resistant barrier against rust, corrosion, and oxidation. Only the WD-40 listing names chassis and suspension use directly; the AstraVox listing names automotive, marine, industrial, and household use without naming chassis parts.
What synthetic brings
The synthetic side has a single example: a moly gray full synthetic grease in a 14.1 OZ cartridge. The listing states a moly-fortified formula for heavy shock loads and metal-to-metal contact, protection for U-joints, bearings, and suspension, and film strength that holds up for extended intervals with fewer reapplications. The listing also states water and washout resistance for wet conditions and high-moisture environments, and a choice of 1, 2, or 3 cartridge packs. No temperature figures are stated on the synthetic listing, so temperature is the one factor where the synthetic side leaves the comparison unclear.
Temperature and washout, as stated
Temperature figures exist only on the lithium side, and they arrive in different units, so no direct ranking follows from them. The WD-40 listing states 0°F to 300°F, and the AstraVox listing states -12°C to 200°C. The Moly listing speaks of high temperatures without giving figures. On moisture, the Moly listing states water and washout resistance and the AstraVox listing states a moisture-resistant barrier. The WD-40 listing states a formula that will not melt, freeze, or run off, which is a temperature claim, not a washout claim. Each listing describes its own product only.
Form and application
Form decides how the grease reaches the joint. The WD-40 spray lays down an even coating through a Smart Straw, which suits sprockets, latches, pulleys, cables, and guide rails. The AstraVox brush is listed for hinges, bearings, and gears. The Moly cartridge suits bearings, suspension, and U-joints, with pack sizes of 1, 2, or 3 cartridges. If the cartridge form appeals, see our grease gun guide for the applicator side.

Matching It to Your Property
- For trailers and off-road equipment in wet ground, the Moly listing states washout resistance and protection for U-joints, bearings, and suspension.
- For chassis and suspension fittings, the WD-40 listing names that use directly and adds a Smart Straw that sprays 2 ways.
- For hinges, bearings, gears, and garage doors around the house, the AstraVox listing pairs a brush with a moisture-resistant barrier.
- For equipment going into storage, the WD-40 listing suggests spraying an even coating on sprockets, latches, pulleys, cables, and guide rails before storage.
The Acre Score explained
The Acre Score weighs five factors: performance, build quality, value, safety, and warranty. A factor the listing does not state scores zero, which is why the examples score zero for safety and warranty. Safety here means stated certifications or operator controls, and none of the listings state any. Scores reflect what each listing states, not a verdict on either side as a whole.
| Product | Acre Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Moly Gray Synthetic | 9.5 | 32 | 21 | 21 | 0 | 0 |
| WD-40 White Lithium | 9.5 | 30 | 21 | 21 | 0 | 0 |
| AstraVox White Lithium | 9.4 | 28 | 20 | 20 | 0 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
Read the manual, keep children and pets out of the yard while you work, wear eye and hearing protection and sturdy footwear, and never exceed the slope rating of your machine. Refuel only with the engine off and cool. See CPSC lawn mower safety. Read our Safety Disclaimer.
FAQ: mowing large lots
Can lithium grease handle chassis work?
Yes, on the evidence of the WD-40 listing, which names chassis and suspension use directly and states a working temperature range of 0°F to 300°F. The AstraVox lithium listing does not name chassis parts, so it is a weaker chassis example than the spray.
What makes the synthetic example different?
The Moly listing states a moly-fortified synthetic formula for heavy shock loads, with film strength for extended intervals and water and washout resistance. Those are the claims that separate it from the two lithium listings.
Do these listings state temperature ranges?
The WD-40 listing states 0°F to 300°F and the AstraVox listing states -12°C to 200°C. The Moly listing states no temperature figures, only that it performs in high temperatures.
Which forms do these greases come in?
The WD-40 listing is a 13.3 OZ spray can, the AstraVox listing is a grease with a brush, and the Moly listing is a 14.1 OZ cartridge with a choice of 1, 2, or 3 cartridge packs.
Is there a warranty on these greases?
None of the listings state a warranty term, so all three examples score zero for warranty. The AstraVox listing mentions customer service without giving a term length.
