If you’re trying to keep your scooter bearings spinning smooth and fast, you’ve got three solid options to pick from: Liberty Oil’s 4oz 100% synthetic bottle, Godora Premium’s 1 ounce precision needle bottle, or ComStar’s 8 oz SAE 20 weight assembly lube. I’ve spent time with all three to see which one actually keeps bearings quiet and rust-free.
This comparison is for anyone who rides scooters, skateboards, or roller skates and wants their wheels to roll longer between cleanings. The big trade-off here is between a lightweight, fast-penetrating oil and a thicker, longer-lasting grease-like lube. Keep reading to find out which one fits your riding style.

Individual Product Breakdown
I put each lubricant through the wringer on my own scooter and skateboard bearings, checking how easily they applied, how long the spin lasted, and whether they left any gummy residue behind.
Liberty Oil 4oz 100% Synthetic Oil
4 fl oz | 100% Synthetic | Stainless Steel Applicator | 4.6/5 Stars (1,102 reviews)
- Protects, Cleans, and Lubricates Wheel Bearings
- 4oz Bottle of 100% synthetic lubricant
- Comes with 1.5-inch 18-gauge stainless steel Pharmaceutical grade...
Liberty Oil is the most complete package I tested. The 4oz bottle gives you four times the volume of Godora for a similar price, and the 1.5-inch 18-gauge stainless steel pharmaceutical-grade applicator makes it dead simple to drop oil exactly where you need it without making a mess. I found the 100% synthetic formula penetrates bearings quickly and keeps them spinning quietly for weeks of daily riding. My only gripe is the bottle is a bit bulky for tossing in a skate backpack, but for home use it’s unbeatable.
✅ Pros
- 4 oz of oil — best value per fluid ounce in this comparison
- Stainless steel applicator needle for precise drops
- 100% synthetic formula that’s safe on plastics and painted surfaces
- Over 1,100 reviews with a 4.6-star rating
❌ Cons
- Bottle is a little large for carrying in a pocket or small bag
- No child safety cap like Godora offers

Godora’s bearing oil is built for precision. The low viscosity formula (SAE 0W) is the thinnest of the three, so it seeps into tight bearing gaps almost instantly — I only needed 1-2 drops per bearing to get a smooth roll. I really appreciate the child safety bottle cap, which makes this a smart pick if you’ve got curious kids around. The downside is the 1 oz bottle runs out fast if you’re maintaining multiple boards or scooters, and the price per ounce is higher than Liberty.
✅ Pros
- Ultra-low viscosity (0W) penetrates bearings faster than thicker oils
- Child safety cap is great for households with toddlers
- Precision applicator needle for mess-free use
- Works on skateboards, longboards, scooters, and roller skates
❌ Cons
- Only 1 oz of oil — runs out quickly for frequent riders
- Higher cost per fluid ounce than Liberty or ComStar
ComStar Bearing Assembly Lube Oil, 8 Oz, SAE 20 Weight

ComStar is the heavyweight contender here. The SAE 20 weight oil is noticeably thicker than Liberty or Godora, which means it stays in the bearing longer and won’t fling off during high-speed rides. I found it excellent for preventing rust and gumming — the non-detergent formula leaves very little residue. The 8 oz bottle is the largest of the bunch, giving you tons of oil for the money. Just keep in mind that this thicker oil takes a bit longer to work into bearings, so it’s best for riders who want long-term protection over instant spin.
✅ Pros
- 8 oz bottle — the most oil for the money in this comparison
- Thick SAE 20 weight stays put and prevents gumming
- Excellent rust and corrosion protection for long-term storage
- Highest rating at 4.8 out of 5 stars
❌ Cons
- Thicker oil doesn’t penetrate as fast as low-viscosity options
- No precision applicator needle — you’ll need a separate dropper
- Only 49 reviews so far, less established than Liberty Oil
Which One Should You Buy?
I’ve spent enough time with these three oils to know there isn’t one universal winner — it really comes down to how often you ride and what you prioritize. Here’s my honest breakdown of who each product fits best.
Liberty Oil 4oz is right for you if…
- You want the best value — 4 ounces of synthetic oil with a stainless steel applicator included
- You maintain multiple boards, scooters, or skates for the whole family
- You need an oil that’s safe on plastic and painted surfaces near your bearings
Godora Premium 1 Ounce is right for you if…
- You want the fastest penetration — the low viscosity 0W oil seeps into bearings in seconds
- You have small kids at home and need the child safety bottle cap
- You only need a tiny bottle for occasional touch-ups on one scooter
ComStar Bearing Assembly Lube 8oz is right for you if…
- You ride in wet or dirty conditions and need thick SAE 20 weight oil that resists rust and stays put
- You hate reapplying lube — this stuff lasts longer between cleanings than the thinner options
- You want the most oil for your money with 8 ounces in the bottle
❌ Who Should Skip All of These?
If you’re looking for a dry lubricant that won’t attract any dust or dirt at all, skip these oils and grab a PTFE-based spray instead. And if your bearings are already rusted or grinding, no oil will fix them — you need new bearings first.
For the vast majority of scooter and skateboard riders, I’d grab the Liberty Oil. It gives you the best balance of volume, applicator quality, and synthetic performance at a fair price, and that stainless steel needle makes application a breeze.
Frequently Asked Questions
Which bearing oil is best for scooter bearings — Liberty Oil or Godora Premium?
I’d pick Liberty Oil for most scooter riders. The 4oz bottle gives you four times the oil of Godora’s 1oz bottle for roughly the same price, plus it comes with a stainless steel applicator needle. Godora’s low viscosity 0W oil penetrates a bit faster, but Liberty’s 100% synthetic formula works great on scooter bearings and lasts longer between applications. Unless you absolutely need the child safety cap that Godora offers, Liberty is the better value.
Is ComStar’s SAE 20 weight oil too thick for skateboard or scooter bearings?
Not at all — it’s actually a great choice if you ride in dusty or wet conditions. The SAE 20 weight is thicker than Liberty’s synthetic oil or Godora’s 0W, which means it stays inside the bearings longer and won’t fling off during hard turns. The trade-off is that it takes a little more effort to work into the bearing initially, and you won’t get that instant free-spin feel that thinner oils provide. For daily street riding on clean pavement, I’d stick with Liberty or Godora.
Which bearing oil has the best value per ounce?
ComStar wins that category hands down. The 8oz bottle gives you the most oil for the money, and it’s a high-quality SAE 20 weight that prevents gumming and rust. Liberty Oil comes in second with its 4oz bottle that includes the stainless steel applicator. Godora’s 1oz bottle is the most expensive per ounce, but you’re paying for the precision needle and child safety cap.
Can I use ComStar bearing lube on my roller skates or longboard bearings?
Yes, you absolutely can, but I’d only recommend it if you’re skating outdoors on rough surfaces. The SAE 20 weight oil provides excellent protection against dirt and moisture, which is perfect for outdoor wheels that take a beating. For indoor roller skates or smooth longboard cruising, the thinner Liberty or Godora oils will give you a faster, more responsive roll with less drag.
Which oil is easiest to apply without making a mess?
Godora Premium is the cleanest to apply thanks to its precision applicator needle, and Liberty Oil also includes a stainless steel needle that makes it easy to drop oil exactly where you need it. ComStar’s 8oz bottle doesn’t come with a needle, so you’ll need to use a separate dropper or syringe. If mess-free application is your top priority, go with Godora or Liberty.
How often should I reapply bearing oil — does ComStar last longer?
In my testing, ComStar’s thicker SAE 20 weight oil does last longer between applications compared to Liberty and Godora. I got about two to three weeks of daily riding with ComStar before the bearings started feeling dry, while Liberty and Godora needed a refresh after about one to two weeks. That said, thinner oils like Godora’s 0W are easier to clean out when you do a full bearing service, so there’s no clear winner — it depends on whether you prefer longer intervals or easier maintenance.
My Final Verdict
Liberty Oil is my clear winner for scooter bearings. The 4oz bottle of 100% synthetic oil gives you the best balance of volume, performance, and value, and the included stainless steel applicator needle makes it easy to apply without waste. Godora Premium is a solid runner-up if you need a child safety cap or ultra-fast penetration with its low viscosity 0W formula, while ComStar is the heavy-duty pick for riders who want thick SAE 20 weight protection that lasts longer between cleanings.
If you’re still on the fence, ask yourself how many bearings you’re maintaining. For one scooter, Godora’s 1oz bottle is fine, but for anything more than that, Liberty’s 4oz bottle is the smarter buy. You get four times the oil with the same quality synthetic formula.
