Lucas Oil Gun Grease and Care Kits: Which Combo Fits You

Best for
Shooters who only need grease

Despite the wording of the listing title, the Lucas Oil Grease Gun Extreme Duty is not a grease gun. It is the 1 oz tube of Lucas Extreme Duty Gun Grease, model 10889, the same grease that ships inside every firearm kit in this list. The listing says it is made in the United States and weighs 1 ounce, and the description references a case of six, although the package quantity is listed as one. That mismatch is worth noting: expect a single tube unless the seller page you land on says otherwise.

The listing itself is thin on performance data. It does not specify a temperature rating or viscosity for this standalone tube, so for those figures you have to look at the kit listings that include the same 10889 part. This pick suits shooters who already own an oil and a cleaner they like and simply need to replace an empty grease tube. If you are starting from scratch, one of the kits further down gives you more for the same trip to the checkout.

• Extreme Duty Gun Grease, part number 10889
• 1 oz tube, 1 ounce item weight
• Country of origin: United States

Best for
Complete bench cleaning and lube

Best for
Minimal grease plus precision oil setup

The Lucas Extreme Duty 1oz Gun Oil kit pairs the 10875 needle oiler with the 10889 grease tube. That is the classic two-part lubrication setup: grease for sliding surfaces that see heavy contact, and thin oil placed precisely with a needle tip on pins, springs, triggers and small moving parts. The listing says both products are made in the USA and designed to protect metal parts from rust, wear and moisture under extreme conditions.

This listing is also where Lucas gives the most detailed specs. It lists an upper temperature rating of 540 °F, a flash point of 212 °C, high viscosity and an SAE J300 viscosity grade of 50. Those figures describe the lubricant in the listing as a whole, and the listing does not separate them by product. The kit suits a shooter who keeps things simple and cleans with whatever solvent they already have. If you want cleaning built into the same routine, the CLP kit is the better step up.

• 1 oz Needle Oiler 10875 and 1 oz Grease Tube 10889
• Upper temperature rating of 540 °F
• Protects against rust, wear and moisture
• Made in the USA

Best for
One-step cleaning with lube backup

The Lucas Oil Extreme Duty 4oz CLP bundle adds a 4 oz bottle of Extreme Duty CLP (10915) to the needle oiler and grease tube. CLP stands for clean, lubricate and protect, and the listing describes it as a one-step product for all three jobs. For most owners who shoot a few boxes at a time, a CLP is the fastest way to wipe down an action, leave a protective film behind and get the gun back in the safe.

A few numbers on the listing do not line up. It shows a liquid volume of 43.9 ml, a unit count of 6 fluid ounces and an item weight of 7.36 ounces. The 6 fluid ounce figure matches the three parts added together (4 oz plus 1 oz plus 1 oz), so we read the 43.9 ml entry as a listing error rather than the real contents. The kit fits a shooter who wants cleaning and lubrication in one bundle but does not need a dedicated solvent for heavy copper fouling. If you do, the five-piece kit covers it.

• Extreme Duty 4 oz CLP 10915
• Extreme Duty 1 oz Needle Oiler 10875
• Extreme Duty 1 oz Gun Grease 10889
• Made in the USA

Best for
High-volume and suppressed rifle shooters

The Prompt Lucas Extreme Duty 4oz Gun oil kit swaps the CLP for a 4 oz bottle of Extreme Duty Gun Oil (10877), alongside the same grease tube and needle oiler. According to the description, this gun oil is formulated for high volume, high heat and high friction firearms, and was designed for full auto firearms, SBRs and suppressors as well as semi-auto rifles, shotguns and pistols. The listing gives a 540 °F upper temperature rating and a 212 °C flash point.

This is the performance-oriented pick. If your range sessions involve long strings of fire, a suppressor that traps heat and gas, or a short-barreled rifle running hot, a dedicated oil makes more sense than a CLP that tries to do everything. The trade-off is that there is no cleaner in the box, so you will need a separate solvent or CLP for the cleaning half of the job. Treat your rifle maintenance like any tuned tool in the workshop: the same care you would give a cordless brad nailer applies here, where clean contact surfaces and the right lubricant keep the action cycling smoothly.

• Extreme Duty 4 oz Gun Oil 10877
• Extreme Duty 1 oz Gun Grease 10889 and Needle Oiler 10875
• Designed for full auto, SBRs and suppressors
• 540 °F upper temperature rating

The Lucas Extreme Duty 4oz Bore Solvent kit is the most complete bundle here. It includes 4 oz of Bore Solvent (10907), 4 oz of Gun Oil (10877), 4 oz of CLP (10915), the 1 oz Needle Oiler (10875) and the 1 oz Gun Grease (10889). The description calls the bore solvent a premium blend of cleaning solvents and corrosion inhibitors that removes carbon and powder residue from actions as well as copper and lead fouling from cylinders and barrels, and notes it is also sold as an ultrasonic gun cleaner.

This kit suits someone who owns several firearms and runs a proper cleaning bench, with a dedicated solvent for the bore, CLP for quick wipe-downs and a gun oil for hot-running guns. The only real overlap is the CLP and gun oil: both lubricate, so casual owners may never use both bottles fully. The listing gives a 4 ounce item weight, which cannot describe five products together, so treat that figure as incomplete. If you shoot occasionally, the CLP kit is the leaner option.

• Bore Solvent 10907, Gun Oil 10877 and CLP 10915, 4 oz each
• Needle Oiler 10875 and Gun Grease 10889, 1 oz each
• Solvent targets carbon, powder, copper and lead fouling

Best for
Vehicles, bearings and farm equipment

The Lucas Oil 14.5 Ounce 10301 Heavy Duty Grease is a different product family. It is a green, 14.5 oz tube recommended for automotive, agricultural and industrial use, and the listing claims it lasts four times longer than regular grease, is virtually waterproof, is stable across temperatures, exceeds lube-for-life specifications and is the ultimate grease for high speed bearings. It is not marketed as a firearm product, and the listing does not mention guns at all.

We include it because many people searching for Lucas grease need it for trailers, wheel bearings, tractors or shop machinery. The listing also shows a liquid volume of 1 gallon, which conflicts with the 14.5 oz size in the title; go by the 14.5 oz figure. A tube this size is typically loaded into a grease gun, which the listing does not include. The same outdoor-gear owner who keeps a foam cannon in the garage for washing a truck will likely find this the right tube for chassis fittings. For firearms, stick with the Extreme Duty products above.
