AMSOIL Synthetic Multi-Purpose Grease is a calcium sulfonate complex, NLGI #2 grease built on premium synthetic base oils for chassis, wheel bearing, and general-service lubrication in passenger cars, trailers, light- and heavy-duty equipment, and powersports. The grease meets the NLGI GC-LB automotive wheel bearing and chassis specification and the NLGI HPM (High Performance Multi-Use) core specification, and is engineered for owners and shops that want one grease for automotive chassis, wheel bearings, U-joints, ball joints, and shop equipment.
The calcium sulfonate complex thickener system gives the grease inherent extreme-pressure performance, water resistance, and thermal stability without relying solely on dosed additives. Premium synthetic base oils bring oxidation resistance and a wide operating temperature window of -40 F to 350 F (-40 C to 177 C). The finished grease is a smooth, tacky red lubricant that pumps cleanly through grease guns and centralized systems.
Heavy chassis loads, shock loading from off-road service, and pressed-fit bushings demand a grease that does not film-fail under pressure. Synthetic Multi-Purpose Grease records a Four-Ball EP Weld Point of 620 kgf (ASTM D2596) and a Timken OK Load of 65 lbs (ASTM D2509), with a Four-Ball Wear scar of 0.40 mm (ASTM D2266). These results support use under heavy and abusive loads in roller bearings, plain bearings, thrust bearings, and pivot points where a general-purpose lithium grease would shear or weld.
Dropping point measures the temperature at which the thickener releases its base oil. The calcium sulfonate complex system carries a dropping point greater than 600 F (greater than 316 C) by ASTM D2265, well above the 350 F upper service temperature, which keeps the grease structured under sustained heat. High-Temperature Life testing on a tapered roller bearing rig (ASTM D3527) records 120 hours, supporting long bearing service in disc-brake-equipped wheel hubs and other heat-soaked positions.
Cold weather hardens conventional greases and starves bearings on the first revolution. Synthetic Multi-Purpose Grease records a low-temperature torque of 8.6 N m at -40 C (ASTM D4693), which is the test value for a grease that flows and pumps to the wear surface in extreme cold. Worked penetration of 280 (ASTM D217, 60 strokes) places the consistency squarely inside the NLGI #2 band for general grease-gun service, automotive chassis points, and central lubrication systems.
Trailer hubs, marine-adjacent applications, agricultural equipment, and power-washed shop equipment lose conventional greases to water. Synthetic Multi-Purpose Grease records 1.5 percent water washout (ASTM D1264) and passes the ASTM D1743 rust and corrosion test, supporting use in wet, washed, and humid service. Oil separation in storage is held to 0.49 percent loss (ASTM D1742) and bearing leakage to 2.3 grams (ASTM D4290), so the grease stays in place during shipping, in inventory, and during operation rather than weeping out of fittings or housings.
Synthetic Multi-Purpose Grease meets the NLGI GC-LB automotive wheel bearing and chassis classification and the NLGI HPM core spec, and is the preferred grease for a wide range of ambient temperatures, environments, and component types:
Maintenance practice matters as much as grease selection. Wipe grease fittings clean before injecting fresh grease to prevent contaminant ingestion. Maintain bearing housings one-third to one-half full of grease and avoid over-greasing, which causes excessive heat buildup. Periodically clean and pack housings with fresh grease on a scheduled interval rather than relying only on top-up service. The grease is compatible with many other types of grease, but when changing greases the equipment should be cleaned of the old grease where possible, or flushed with a liberal amount of Synthetic Multi-Purpose Grease while the mechanism is in operation, then closely monitored for any inconsistencies.

Have not yet used this but am glad it was given free with my last order
Would recommend this to a friend.
Man I love this stuff, and not just because it was free with my last order, I needed some for various needs around the garage. I couldn't help myself, I even used it on my Luminox Navy Seal wrist watch when I was replacing the O-ring back cover seal. So far, so good. Its official, I am an Amsoil fan, I have the Garage stool, the clock and Amsoil stickers everywhere. Its silly actually, but I don't cae. Good products are worth bragging about. Thanks Amsoil!

Long lasting compared to the cheap stuff

It is a single grease for automotive chassis points, wheel bearings, universal joints, ball joints, tie-rod ends, and steering knuckles, plus shop and industrial roller bearings, plain bearings, thrust bearings, gears, electric motors, presses, winches, and bushings. The NLGI GC-LB and HPM ratings cover both automotive wheel bearing and chassis service and the broader high-performance multi-use category.
Yes. The NLGI GC-LB performance grade is the wheel bearing and chassis classification, and the formula is rated for the operating range a sealed disc-brake hub sees, with a dropping point greater than 600 F and 120 hours in the ASTM D3527 high-temperature wheel bearing life test. It is suited to passenger car, light-truck, and trailer wheel bearings.
No. Caliper slide pins, piston boots, and brake-pad backing-plate contact areas need a silicone-based caliper assembly lubricant designed for compatibility with rubber seals and brake hardware. Synthetic Multi-Purpose Grease is for chassis, bearing, and general lubrication points outside the brake friction system.
Calcium sulfonate complex thickeners deliver inherent water resistance, rust protection, and EP performance from the thickener itself, rather than depending on supplemental EP additives. The result is a high dropping point greater than 600 F, low water washout of 1.5 percent in ASTM D1264, and a 620 kgf Four-Ball EP Weld Point in a single product that can replace several lithium-based shop greases.
The grease is rated for service from -40 F to 350 F (-40 C to 177 C). At the cold end, low-temperature torque at -40 C is 8.6 N m by ASTM D4693, supporting cold-start pumpability in cold-climate trailers and equipment. At the hot end, the dropping point greater than 600 F gives a wide margin above the upper service temperature.
Synthetic Multi-Purpose Grease is compatible with many other grease types. When changing greases, the equipment should be cleaned of the old grease where possible or flushed with a liberal amount of Synthetic Multi-Purpose Grease while the mechanism is in operation, then closely monitored for any inconsistencies. Compatibility questions for unusual chemistries should be referred to an AMSOIL representative or AMSOIL INC. at (715) 392-7101.
No. Using AMSOIL synthetic lubricants does not void a new vehicle or equipment manufacturer warranty, and Synthetic Multi-Purpose Grease is covered by the AMSOIL Limited Liability Warranty.
