Buying guide: choosing the best synthetic chassis grease under $10
Synthetic on the label vs lithium on the label
Only the Mobil 1 listing titles its grease synthetic. The Mystik is a lithium complex grease, the LubriMatic and MotorKote are lithium greases, and the Lucas is a marine grease, with no synthetic claim in their titles. A buyer who wants the synthetic label should pick the Mobil 1; a buyer who wants the strongest stated credentials should weigh the Mystik.
NLGI grade and container
NLGI grade is stated for three picks: NLGI 2 for the Mystik and the MotorKote, and NLGI 1-1/2 for the LubriMatic, while the Lucas and Mobil listings state no NLGI grade. For loading, the Mystik tube is titled for grease gun use, the Lucas and Mobil listings state cartridges, and the LubriMatic states a can, so check the format against the gun on the shelf. For trailer work, the Lucas listing names trailer chassis lubrication and trailer wheel bearings, and the tow-behind attachments hub covers the trailers those fittings belong to.
Load and heat figures, stated only
Compare only figures the listings state. The MotorKote exceeds a 70 lb OK load under ASTM D-2509 and states use up to 302°F, the LubriMatic states a drop point of 350 degrees F and pumping to -10 to -15 degrees F, the Mystik states a viscosity of 630 centistokes, the Mobil states 150 mm2/s at 40°C with an SAE grade of 15W-40, and the Lucas states an SAE grade of 75W-140. No listing here states a full temperature range.
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.
Matching It to Your Property
- Match the container to the grease gun: tubes and cartridges are the gun formats stated here, while the can needs a different approach.
- For wet ground or trailer work, the Lucas states marine use, and the MotorKote states resistance to water washout.
- For high-heat fittings, compare the stated figures: use up to 302°F for the MotorKote, and a drop point of 350 degrees F for the LubriMatic.
- For chassis and universal joints, the Mystik states Rockwell and Spicer approval, and the LubriMatic names both in its recommended uses.
The Acre Score explained
The Acre Score weighs five factors: performance (grease type, NLGI grade and stated load and heat figures), build quality (container and consistency data the listing states), value (specs for the money), safety (stated certifications) and warranty (a concrete term). No listing here states a warranty term with a concrete length, so warranty scores zero across the group, and only the Mystik states a certification.
| Product | Acre Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Mystik JT-6 | 9.6 | 32 | 22 | 21 | 5 | 0 |
| Mobil 1 Synthetic | 9.5 | 30 | 21 | 21 | 0 | 0 |
| MotorKote Sticky Red | 9.5 | 30 | 21 | 20 | 0 | 0 |
| LubriMatic 11316 | 9.4 | 29 | 20 | 20 | 0 | 0 |
| Lucas Oil 10320 | 9.4 | 28 | 20 | 19 | 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.
