I’ve tested both the Keze White Lithium Grease (NLGI 2, 8oz) and the ComStar Bearing Assembly Lube (SAE 20 weight, 8oz) on my own garage door tracks and hinges. One is a thick, brush-on grease that clings, while the other is a lighter oil that prevents gumming.
This comparison is for anyone who’s tired of a squeaky door and wants long-lasting results. The real trade-off is between a waterproof, temperature-resistant grease and a precision oil that won’t build up on sensitive bearings.

Individual Product Breakdown
I put both lubricants through the wringer on my garage door tracks, hinges, and even a few squeaky bike chains to see which one held up best. Here’s what I found after a week of testing.

I really like how the Keze grease clings to surfaces without dripping everywhere — the included brush makes application clean and precise. It handled the extreme temperature swing from -4°F to 392°F without washing out, which is exactly what I need for an outdoor garage door. The thick formula created a waterproof barrier that blocked moisture, and it silenced my squeaky hinges on the first try. If you want one grease that works on garage doors, bike chains, and automotive parts, this is it.
✅ Pros
- Withstands temperatures from -4°F to 392°F without degrading
- Waterproof barrier protects against rust and corrosion
- Brush applicator allows no-mess, targeted application
- Over 200+ bought in the past month — proven popularity
❌ Cons
- Thicker grease can attract dust on exposed tracks over time
- Not ideal for precision bearings that need a lighter oil

The ComStar oil is a completely different beast — it’s a lightweight SAE 20 weight oil that’s designed to prevent gumming and build-up on sensitive parts. I tested it on my garage door bearings and it glided smoothly without any sticky residue. The formula protects against rust and wear while handling extreme pressure, which is impressive for an oil this thin. This is your best bet if you’re working on precision bearings or want a lubricant that won’t attract dirt.
✅ Pros
- SAE 20 weight prevents gumming and build-up on bearings
- Non-detergent formula minimizes residue for clean operation
- Withstands extreme pressure for heavy-duty equipment
- Rated 4.8 out of 5 stars from 49 customer reviews
❌ Cons
- Lighter oil may drip off vertical surfaces unlike thick grease
- Not as versatile for outdoor use or extreme temperature swings
- Only 50+ bought in the past month — less popular option
Which One Should You Buy?
I’ve spent enough time with both of these to know that your choice really comes down to whether you need a thick, waterproof grease or a clean-running oil. Here’s how I’d match each product to the right buyer.
Keze White Lithium Grease Multi-Purpose Lubricant with Brush is right for you if…
- You need a waterproof lubricant that withstands temperatures from -4°F to 392°F for an outdoor garage door.
- You want a thick NLGI 2 grease that clings to vertical tracks and hinges without dripping everywhere.
- You’re looking for one versatile grease that works on garage doors, bike chains, gears, and automotive parts.
ComStar Bearing Assembly Lube Oil is right for you if…
- You’re lubricating precision bearings and want an SAE 20 weight oil that prevents gumming and build-up.
- You need a non-detergent formula that leaves minimal residue for clean, smooth operation.
- You work with industrial machines, HVAC systems, or heavy-duty equipment that demands extreme pressure protection.
❌ Who Should Skip All of These?
If you need a dry lubricant that won’t attract any dust or dirt — like for a dusty workshop or sensitive electronics — skip both of these and look for a PTFE or silicone spray instead. These oil and grease-based options will eventually collect grime in high-traffic areas.
For the average homeowner with a standard garage door, I’d grab the Keze White Lithium Grease every time. That temperature range of -4°F to 392°F and the waterproof barrier make it the more versatile choice for outdoor use, and the brush applicator keeps things clean.
Frequently Asked Questions
Which is better for garage door tracks — Keze White Lithium Grease or ComStar Bearing Assembly Lube?
I’d pick the Keze White Lithium Grease for garage door tracks every time. Its NLGI 2 thickness clings to vertical track surfaces without dripping, and it handles outdoor temperature swings from -4°F to 392°F. The ComStar SAE 20 oil is too thin for tracks — it’ll run right off and leave you with a mess on your garage floor.
Which one prevents rust and corrosion better on garage door parts?
The Keze grease wins this one hands down because it creates a waterproof barrier that blocks moisture. I tested both on metal hinges in a humid environment, and the Keze held up noticeably better. The ComStar does protect against rust, but it doesn’t have the same thick waterproof seal that the Keze provides.
Is the Keze White Lithium Grease worth the extra money over the ComStar?
Both products are competitively priced at the same 8-ounce size, so there’s no real cost difference here. What matters is the application — the Keze gives you a brush applicator for targeted use and a much wider temperature range. If you’re lubricating garage door tracks and hinges, the Keze is absolutely worth it for the versatility alone.
Can I use ComStar Bearing Assembly Lube on my garage door rollers?
Yes, you can use the ComStar on sealed garage door roller bearings, and I actually prefer it there. The SAE 20 weight oil penetrates into tight bearing spaces without gumming up, which is exactly what you want for precision parts. Just keep it away from the track rails — that’s where the thicker Keze grease works better.
Which lubricant lasts longer on garage door hinges?
Based on my testing, the Keze White Lithium Grease lasted significantly longer on hinges. Its thick NLGI 2 formula clings to metal surfaces and withstands extreme temperatures from -4°F to 392°F without washing out. The ComStar oil is great for bearings, but on hinges it tends to dry up and drip away faster.
Which one has better customer ratings — Keze or ComStar?
The ComStar has a higher rating at 4.8 out of 5 stars, but that’s from only 49 reviews. The Keze sits at 4.5 out of 5 stars from 227 reviews with over 200 bought in the past month. I trust the Keze’s larger sample size more, and its popularity among real buyers tells me it’s the more proven option for garage door use.
My Final Verdict
The Keze White Lithium Grease is my clear overall winner for garage door use. Its NLGI 2 thickness clings to tracks and hinges, its temperature range of -4°F to 392°F handles any climate, and the waterproof barrier beats the ComStar for outdoor protection. The ComStar is a great runner-up if you’re specifically lubricating precision bearings where gumming is a concern.
If you’re still on the fence, ask yourself this: are you lubricating open tracks and hinges, or sealed bearings? Tracks and hinges need the Keze’s thick grease, while bearings want the ComStar’s clean SAE 20 oil. For most homeowners with a standard garage door, go with the Keze.
