AMSOIL X-Treme Synthetic Food-Grade Grease
AMSOIL X-Treme Synthetic Food-Grade Grease is an ultra-premium NLGI #2 aluminum complex grease formulated for food-processing, beverage, and pharmaceutical-industry equipment where incidental food contact is possible. The product is registered H-1 by NSF (Registration No. 172163) and meets the requirements of FDA 21 CFR 178.3570 for non-toxic additive chemistry.
NSF H-1 registration for incidental food contact
X-Treme Synthetic Food-Grade Grease is registered Category H-1 by NSF for use as a lubricant in and around food-processing areas. The formulation uses non-toxic additives compliant with FDA 21 CFR 178.3570, the federal regulation that governs lubricants where incidental contact with food is possible. That makes the grease appropriate for bakery line bearings, dairy mixer pivots, brewery conveyor rollers, meat-processing equipment, beverage bottling-line slides, and packaging-machinery linkages where a standard lithium or barium grease cannot be specified.
Aluminum complex thickener for stability and washdown resistance
The aluminum complex thickener gives X-Treme Synthetic Food-Grade Grease a 525°F (273°C) dropping point by ASTM D2265, strong adhesion to bearing surfaces, and proven resistance to plant washdown chemicals and direct water spray. Water washout loss measures 5.4 percent (ASTM D1264), keeping the grease in place during high-pressure rinses and steam cleaning. Treated bearings stay protected against rust and corrosion, confirmed by a Pass result on the ASTM D1743 rust test.
Wide operating temperature range
X-Treme Synthetic Food-Grade Grease provides exceptional performance across a continuous operating temperature range of -49°F to 392°F (-45°C to 200°C), with intermittent service tolerated up to 482°F (250°C). One grease covers walk-in cooler conveyors, blast freezer chain pins, and the hot bearing housings found on commercial ovens, baking lines, fryers, and pasteurization equipment, without rotating between a separate winter and summer product.
Extreme-pressure load capacity
The formulation carries a 315 kgf Four-Ball EP weld point (ASTM D2596), a Load Wear Index of 44, and a 40 lbs Timken OK load (ASTM D2509). Four-Ball wear by ASTM D2266 measures 0.5 mm scar. These extreme-pressure numbers reduce friction and heat generation in heavily loaded chassis, conveyor, and roll-line bearings and help eliminate metal-to-metal contact in shock-loaded service common to food and beverage lines.
High-temperature life and cold-start pumpability
High-temperature bearing life by ASTM D3527 returns 48 hours, supporting extended re-greasing intervals on hot, continuously running food-processing bearings. Low-temperature torque measures 2.7 N·m at -40°C (-40°F) by ASTM D4693, so equipment pulled from a freezer line or started on a cold winter morning still pumps grease through fittings and central lubrication systems.
Grease compatibility and changeover
X-Treme Synthetic Food-Grade Grease is compatible with lithium complex, calcium 12-hydroxy, and other aluminum complex greases. It is not compatible with barium, bentonite clay, calcium, calcium complex, lithium, lithium 12-hydroxy, polyurea, or sodium greases. When switching from an incompatible grease type, complete purging of the bearing housing is required to avoid thickener interaction and consistency breakdown.
Recommended applications and service intervals
Use X-Treme Synthetic Food-Grade Grease in food-service, beverage, and pharmaceutical-industry equipment, including preparation, processing, and packaging machinery where incidental food contact is possible. Typical service points include processing-line bearings, conveyor rollers and pins, packaging-machinery linkages, mixer pivots, slicer slides, and clean-in-place loop pumps. The grease also covers ancillary equipment in the same plant where avoiding cross-contamination with an industrial chassis grease matters.
- Maintain bearing housings one-third to one-half full of grease. Over-greasing can result in excessive heat buildup.
- Wipe grease fittings clean before injecting grease to prevent contaminant ingestion into the housing.
- Supplement standard greasing by periodically cleaning and re-packing housings with fresh grease on an established maintenance schedule.
- For non-food-contact heavy-duty chassis bearings, a polymeric chassis grease or high-viscosity lithium complex grease may be a better match. Use the grease selection guide for options outside food-contact service.
Confirm the equipment OEM lubrication chart calls for an NLGI #2 aluminum complex or compatible product before changeover, and avoid mixing with non-NSF H-1 lubricants in food-contact zones. The grease is intended for the applications recommended in the product data sheet and is not authorized for racing, modified industrial use, or service outside the operating temperature range above.

Frequently asked questions
What does NSF H-1 registration mean for a food-grade grease?
NSF Category H-1 covers lubricants approved for use in food-processing environments where incidental food contact is possible. X-Treme Synthetic Food-Grade Grease holds NSF Registration No. 172163 and is formulated with non-toxic additives that comply with FDA 21 CFR 178.3570.
Is X-Treme Synthetic Food-Grade Grease an NLGI 2 grease?
Yes. The product is an NLGI #2 aluminum complex grease with a worked penetration of 280 by ASTM D217. NLGI 2 is the most common consistency for bearings, conveyors, and packaging-line linkages on food-processing equipment.
What is the operating temperature range?
X-Treme Synthetic Food-Grade Grease provides continuous service from -49°F to 392°F (-45°C to 200°C) and tolerates intermittent excursions up to 482°F (250°C). The range supports freezer-line conveyors and hot oven, fryer, and pasteurizer bearings without changing grease seasonally.
How well does the grease resist plant washdown?
Water washout loss measures 5.4 percent by ASTM D1264, and ASTM D1743 rust and corrosion testing returns a Pass result. The grease stays in place during high-pressure wash and rinse cycles and continues to protect bearings against water ingress, rust, and corrosion.
Can X-Treme Synthetic Food-Grade Grease be mixed with the current plant grease?
The product is compatible with lithium complex, calcium 12-hydroxy, and other aluminum complex greases. It is not compatible with barium, bentonite clay, calcium, calcium complex, lithium, lithium 12-hydroxy, polyurea, or sodium greases. When switching from an incompatible grease, complete purging of the bearing housing is required.
What package sizes are available?
Available sizes include the 14 oz. cartridge , 40-pack of 14 oz. cartridges , case of ten 14 oz. cartridges , 35 lb. lug , and 120 lb. keg . Plant-scale orders are easy to support with the keg and lug formats.
