Boeshield T-9 Review

Boeshield T-9 Review



The bottom line is that Boeshield T-9 costs a couple of dollars more than comparable bike chain lubricants from popular competitors.

Based on my experience using the lube for more than 1,000 miles, as well as online customer feedback, though, the extra expense seems to pay off from a value perspective.

Boeshield T-9 lubricant uses patented technology from Boeing to help prevent corrosion, rust, and dirt accumulation on your bike chain (along with many other uses). Is it necessarily worth the extra money, though? Here’s what we learned after extensive testing.

About Boeshield T-9

Boeshield T-9 is an all-in-one formula that promises to deliver waterproof lubrication, protection against rust and corrosion, a barrier against dirt and debris, and deep cleaning, whether the conditions are wet or dry.

It works using a unique solvent and paraffin wax formula that creates a thin, continuous film on any metal surface. In turn, this can keep your bike’s chain free from moisture, dust, dirt, and mud for up to 200 miles.

According to the company, Boeshield T-9 isn’t just for bicycle chains, either. You can also use it on drivetrains, (including derailleur and in between rollers and pins), brake and shift cables, caliper and pedal pivots, seat posts, spoke nipples, and inside frames.

Its nonconductive formula also works to address corrosion, flush out old lubricants, and loosen rusty parts on, whether dry or wet (e.g., electrical motors, circuits, ignitions, and connectors), or lubricate just about any metal pivot point by deeply penetrating its pores.

Despite all of these benefits, the company advertises that T-9 won’t harm common materials like paint, plastic, rubber, fiberglass, or vinyl and that it performs better than Teflon.

Exactly what does this formula contain, though?

Taking a Closer Look at Boeshield T-9’s Ingredients

Although Boeshield T-9 is manufactured and distributed by Holland, MI-based PMS Products, Inc., it’s an officially licensed from The Boeing Co. In other words, Boeing developed the lube and allows PMS to distribute it.

According to the lubricant’s Safety Data Sheet, the amber, combustible liquid contains the following ingredients:

Ingredient Percentage
Distillates (petroleum) 40-50%
Naphtha (petroleum), hydrotreated heavy 20-30%
Petroleum Oil 10-15%
Petrolatum 1-5%
Oil Soluble Sodium Sulfonate 1-5%
Sorbitan Tristearate 1-5%

In addition to 4 oz. drip and bike bottles, PMS Products also offers Boeshield T-9 liquid in 4 oz and 12 oz aerosol cans, as well as in one-gallon jugs. However, based on their safety data sheets, there aren’t any differences in their core ingredients.

How to Apply Boeshield T-9

Despite its unique formula, you’ll apply Boeshield T-9 similar to many other bike chain lubes:

  1. Clean your chain
  2. Apply the liquid to the chain
  3. Adjust speeds and gears evenly to distribute the product and allow to dry
  4. Wipe off excess after two hours, or overnight

My Experience Using Boeshield T-9 Liquid

T-9’s Price

Despite its availability from several popular online retailers like Amazon, REI, and The Rust Store for between $10 and $11, I picked up my 4 oz bottle from a local bike shop for about the same amount of money.

This is roughly $1-$2 more than many competing bike chain lubes from third-party manufacturers.

Ease of Application

As you might expect, there’s not a whole lot to it. Simply shake T-9’s bottle, apply as instructed by the manufacturer, wipe off any excess, and wait overnight (ideally) before heading out on a ride.

I’ve found that the nozzle doesn’t clog. A 4 oz bottle typically lasts me the better part of a year, even while maintaining a stable of 6+ kids and adult bikes.

When it comes to Boeshield T-9, I’ve found that more isn’t better. In fact, you will need to make sure and wipe off any excess after applying. Otherwise, it will quickly attract quite a bit of dirt and tend to gum up.

Real-World Performance

After using the lubricant for well over 1,000 miles, I’ve found that T-9’s formula repels water exceptionally well and lasts more 100 miles before requiring reapplication, depending on the conditions you primarily ride in (the more wet/severe, the more often you’ll need to refresh).

Removal & Cleaning

When the time comes, I remove the waxy formula using WD-40 Chain Cleaner & Degreaser for my entire drivetrain, along with the Park Tool GearClean Brush (and a bit of elbow grease) for my cassette and chainrings. I finish off using the Finish Line Grunge Brush on my chain.

Odor & Storage

Although I’ve never noticed an overwhelming odor from T-9’s formula, the company recommends using in a well-ventilated area. It doesn’t freeze, so you can store it in your garage or shed, although it is flammable so be sure to keep it away from extreme heat.

Coming to a Conclusion About Boeshield T-9

The ‘perfect’ bike chain lubricant is a highly individual decision and depends on essential factors like where you ride, prevailing weather and ground conditions, how often you plan to refresh, and whether or not you have sufficient time between application and riding.

Boeshield T-9 Benefits

With these details in mind, I’ve had great luck with Boeshield T-9. It’s super easy to apply, delivers excellent lubrication and rust resistance, doesn’t fling off (as long as it’s allowed sufficient time to dry), and lasts 100+ miles, depending on conditions.

In addition, it’s incredibly versatile and can be used on all manner of metal bike parts, including the drivetrain, your dropper post, and cables and cable housing. It can also be used extensively around the house on door hinges, firearms, power tools, and even for woodworkers on top of their table saws.

Between websites like Amazon, MTBR, and REI, most customers seem to give Boeshield T-9 liquid an average rating of 4.5+ stars, frequently citing that it delivers meaningfully better protection and durability than other popular bike chain lubes. In fact, more than one claimed it was their favorite chain lube at the time of our research.

Potential Boeshield T-9 Drawbacks

With these details in mind, T-9 is priced a couple of dollars higher (or more) than similar options from companies like WD-40, Finish Line, ProGold Prolink, and White Lightning.

In my opinion, though, T-9 offers longer-lasting performance than many other brands—so much so that it’s currently my preferred bike chain lube—and consequently, a great deal of bang-for-your-buck.

Just remember that you need to let it set overnight (ideally) to provide maximum performance benefits, which might be its only downfall, IMO.
