I’ve spent time with both the Lincoln 1162 and the OTC 2310 pneumatic grease guns, and they take very different approaches to the same job. The Lincoln pumps out a serious 6,000 PSI and has over 2,100 reviews, while the OTC 2310 is a simpler, lighter option that’s been around since 2013.
If you’re a shop mechanic or a DIYer who greases heavy equipment daily, you need a gun that won’t quit. I’ll break down the real-world differences in power, build quality, and convenience so you can pick the right one for your shop.

Full Specs Comparison
I’ve lined up every spec from both guns side by side so you can see exactly where each one shines. Here’s how the Lincoln 1162 and OTC 2310 stack up on paper.
The Lincoln 1162 wins on pressure, hose reach, and customer satisfaction by a mile, but the OTC 2310 is noticeably lighter and includes a handy bent extension. For my shop work, that 6,000 PSI and variable speed trigger make the Lincoln the clear standout.
Individual Product Breakdown
I put both grease guns through their paces in my shop, focusing on real-world performance, build quality, and ease of use. Here’s what I found with each one.
Lincoln 1162 Pneumatic Grease Gun with 30″ High-Pressure Hose and Coupler
6,000 PSI | Variable Speed Trigger | 30-inch Hose | 5.6 lbs | 4.6/5 Stars

- DURABLE 30-INCH HOSE AND COUPLER: The 30-inch high-pressure hose with...
The Lincoln 1162 is the best pneumatic grease gun I’ve used in my shop. That 6,000 PSI rating means it powers through stubborn zerk fittings on heavy equipment and CV joints without any hesitation, and the variable speed trigger gives me precise control over grease flow. The 30-inch high-pressure hose reaches tight spots on suspension systems and machinery that shorter hoses just can’t get to. My only real complaint is the weight — at 5.6 pounds it’s a bit heavier than the OTC, which can make long jobs a little more tiring on the wrist.
✅ Pros
- Massive 6,000 PSI for high-pressure applications like CV joints
- Variable speed trigger gives you full control over grease flow
- 30-inch hose reaches tight spots other guns can’t
- Over 2,100 reviews with a 4.6-star average — real user trust
❌ Cons
- Heavier than the OTC at 5.6 pounds
- No included extension for extra reach on tight fittings
OTC 2310 Air Operated Grease Gun
Die Cast Aluminum Head | Automatic Air Bleeder | 24-inch Hose | 5 lbs | 3.6/5 Stars
- Heavy duty die cast aluminum head
- The head is fitted with an automatic air bleeder
- Larger pumping chamber honed for rapid operation
The OTC 2310 is a solid budget-friendly option that’s lighter and easier to handle than the Lincoln, coming in at exactly 5 pounds. I like the heavy-duty die cast aluminum head and the automatic air bleeder, which saves you from manually purging air out of the system. The included 6-inch bent steel extension is a nice bonus for reaching awkward fittings, but the 24-inch hose is noticeably shorter than the Lincoln’s. The 3.6-star rating from only 108 reviews tells me it doesn’t have the same track record, and I found it doesn’t deliver the same raw power for heavy-duty jobs.
✅ Pros
- Lighter at 5 pounds — easier on your arm for long sessions
- Automatic air bleeder makes setup quick and hassle-free
- Comes with a 6-inch bent steel extension for tight fittings
- Heavy-duty die cast aluminum head for durability
❌ Cons
- Only 3.6 stars from 108 reviews — less proven than the Lincoln
- 24-inch hose is shorter than the Lincoln’s 30-inch hose
- No published PSI rating, so you don’t know max pressure
Which One Should You Buy?
I’ve spent enough time with both guns to know that your choice really comes down to how demanding your shop work is. Here’s who I’d point toward each one.
Lincoln 1162 Pneumatic Grease Gun is right for you if…
- You regularly grease heavy equipment that needs the full 6,000 PSI to push through tough fittings like CV joints and bearings
- You need a variable speed trigger to control grease flow precisely on sensitive components
- You want a proven tool backed by over 2,100 customer reviews and a 4.6-star rating
OTC 2310 Air Operated Grease Gun is right for you if…
- You want a lighter gun at 5 pounds for less fatigue during long greasing sessions
- You need the included 6-inch bent steel extension to reach awkward zerk fittings on compact machinery
- You prefer an automatic air bleeder that saves you from manually purging air during setup
❌ Who Should Skip All of These?
If you only grease a few fittings on your personal car once a month, a manual grease gun will save you money and hassle without needing an air compressor. These pneumatic guns are overkill for light-duty home use.
For most shop mechanics and heavy-duty DIYers, the Lincoln 1162 is the clear winner with its 6,000 PSI power, longer 30-inch hose, and proven reliability. It’s the one I keep reaching for every day.
Frequently Asked Questions
Which is better for heavy shop use, the Lincoln 1162 or the OTC 2310?
The Lincoln 1162 is better for heavy shop use, plain and simple. It delivers 6,000 PSI compared to the OTC’s unrated pressure, and that power makes a real difference when you’re greasing CV joints and bearings on trucks and tractors. The Lincoln also has a 30-inch hose versus the OTC’s 24-inch hose, so you can reach more fittings without moving the gun around. I’d only pick the OTC if weight is your main concern, since it’s 0.6 pounds lighter.
Is the Lincoln 1162 worth paying more than the OTC 2310?
Yes, absolutely, if you do any kind of professional or heavy-duty work. The Lincoln has over 2,100 reviews with a 4.6-star average, while the OTC sits at 3.6 stars from just 108 reviews — that’s a massive gap in real-world trust. You’re getting a variable speed trigger, a longer hose, and proven 6,000 PSI performance that the OTC simply doesn’t match. For light home use, you might save money with the OTC, but for a shop, the Lincoln is worth every penny.
Which grease gun has a longer hose, the Lincoln 1162 or the OTC 2310?
The Lincoln 1162 has the longer hose at 30 inches, while the OTC 2310 comes with a 24-inch hose. That extra 6 inches on the Lincoln makes a noticeable difference when you’re trying to reach fittings tucked behind suspension components or inside machinery. If you work on equipment with tight access, the Lincoln’s longer hose is a real advantage.
Does the OTC 2310 come with an extension for hard-to-reach fittings?
Yes, the OTC 2310 includes a 6-inch bent steel extension, which the Lincoln 1162 does not include. That extension is handy for greasing fittings in awkward spots like u-joints or tight engine bays. If you often deal with hard-to-reach zerks, the OTC’s included extension is a nice bonus, though you can always add a separate extension to the Lincoln.
Which grease gun has better customer reviews, the Lincoln or the OTC?
The Lincoln 1162 has far better reviews — 4.6 stars out of 5 from over 2,100 customers, compared to the OTC 2310’s 3.6 stars from just 108 reviews. That’s a huge difference in both rating and sample size, which tells me the Lincoln is a much more proven product. I always trust a tool that thousands of other mechanics have put through the wringer.
Can I use the Lincoln 1162 with standard 14 oz grease cartridges?
The Lincoln 1162 doesn’t specify a cartridge size in its specs, but it uses a combination filler coupler that works with bulk grease or cartridge-loading systems. The OTC 2310 is explicitly designed for 14 oz grease cartridges, so if you prefer standard cartridges, the OTC is more straightforward. I’d recommend checking the Lincoln’s product page for cartridge compatibility before buying.
My Final Verdict
The Lincoln 1162 is my clear overall winner for shop use — it delivers a proven 6,000 PSI, a longer 30-inch hose, and a 4.6-star rating from over 2,100 buyers that the OTC 2310 simply can’t match. The OTC 2310 is the runner-up that makes sense if you want a lighter 5-pound gun with an included bent extension for tight spots, but it lacks the power and track record for heavy-duty work. For any shop that greases equipment daily, the Lincoln is the only choice.
If you’re on the fence, ask yourself one question: do you need raw power to push grease through stubborn fittings, or is saving a few bucks more important? For most mechanics, that 6,000 PSI and variable speed trigger on the Lincoln will pay for itself in time saved and frustration avoided.

- Heavy duty die cast aluminum head
- The head is fitted with an automatic air bleeder

Best for light-duty shop work or DIYers who prioritize a lighter tool at 5 pounds with an included 6-inch bent extension. It works fine for basic greasing but lacks the power and proven reliability of the Lincoln.
