The Pinewood Derby is a classic event that combines woodworking, physics, and a healthy dose of competition. For many, the quest for speed leads to meticulous car design and, crucially, finding the perfect lubricant for the wheels. Among the various oils and greases discussed in forums and workshops, air tool oil sometimes emerges as a contender. But is air tool oil really a good option for your Pinewood Derby car? As car experts at carscannertool.store, we delve into the specifics to help you make the fastest decision.
Understanding Pinewood Derby Car Lubrication
In the world of Pinewood Derby racing, even the slightest edge can mean the difference between victory and defeat. With races often decided by thousandths of a second, minimizing friction is paramount. The wheel bearings and axles are where lubrication plays its most critical role. Reduced friction here translates directly into increased speed and potentially shaving off those vital fractions of a second. Choosing the right lubricant is not just about applying any oil; it’s about selecting a product that offers the lowest possible resistance under the specific conditions of a Pinewood Derby race.
Air Tool Oil: An Unconventional Lubricant for Derby Cars?
Air tool oil is designed for pneumatic tools, focusing on reducing friction and wear in high-speed, air-powered machinery. Its properties often include low viscosity to ensure smooth operation and additives to prevent rust and corrosion. When considering air tool oil for Pinewood Derby cars, the question isn’t immediately obvious. While it’s formulated for reducing friction, the context is quite different from a high-speed air tool. However, the core principle of friction reduction remains relevant.

Some enthusiasts suggest that air tool oil’s low viscosity and lubricating properties could indeed be beneficial for Pinewood Derby cars. The original article we’re referencing mentions air tool oil as a viable option, recommending cleaning bearings with isopropyl alcohol and then lightly lubricating with air tool oil. This suggests that there’s a practical basis for considering it, especially given the emphasis on not over-lubricating.
Expert and Enthusiast Opinions on Pinewood Derby Lubricants
To get a broader perspective, let’s look at other lubricant options and expert opinions shared in the original forum discussion:
Krytox: The High-Tech, High-Cost Option
Krytox is mentioned as a high-end lubricant, known for its exceptional slipperiness. It’s a synthetic grease with a high price tag, often recommended for its superior performance in reducing friction. In the original query, the racer mentions using Krytox, indicating its popularity among those seeking top performance. However, its cost and availability might be a barrier for some.
STP Oil Treatment: The Viscous Choice for Load
STP Oil Treatment, suggested by Jim Sivertsen, is a much thicker oil, traditionally used in engines to improve oil viscosity and reduce wear. While seemingly counterintuitive for low-friction applications, Jim recommends it based on its effectiveness in severe conditions like deep drawing and swaging. For Pinewood Derby cars, which can weigh up to 255 lbs with a driver for Soap Box Derby, the load-bearing capability of STP might be relevant, although Pinewood Derby cars are significantly lighter.
Militec-1: The Metal Conditioner
Militec-1 is another product highlighted as “the best lubricant for all mechanical devices” in one of the responses. It’s described as a synthetic metal conditioner that reduces friction and doesn’t attract as much dirt. This is a significant advantage, as cleaner bearings mean less resistance. The 64th Greater Washington D.C. Soap Box derby even provided samples to entrants, suggesting its credibility in racing circles.
Teflon/PTFE: The Dry Lubrication Approach
Teflon (PTFE) is suggested as a dry lubricant option. Freeman Newton, in the original discussion, points out Teflon’s low friction properties, especially for short races where heat buildup is minimal. Teflon can be applied as a powder or spray, offering a different approach to lubrication compared to oils and greases. The idea of “clean and dry” for maximum speed, as suggested by Ryan in the original question, aligns with the principle behind dry lubricants like Teflon.
Castor Oil: The Old-School, Bio-Based Lubricant
Castor oil is mentioned as a lubricant used in derbies in the past. Joe Luke shares this historical insight, pointing to a time when natural oils were more common. Castor oil has good lubricating properties and is biodegradable, but modern synthetic oils often outperform it in terms of friction reduction and longevity.
Cleaning Your Pinewood Derby Car Bearings: A Crucial Step
Regardless of the lubricant you choose, properly cleaning the bearings is essential. Ryan, in the initial question, mentions using Brakleen to clean bearings, while Craig Murray suggests isopropyl alcohol. Tommy Gullett recommends brake cleaner. Lighter fluid is also mentioned as a common cleaning and lubricating agent.

The consensus is clear: clean bearings are faster bearings. Dirt and debris are significant friction contributors. Isopropyl alcohol, brake cleaner, and lighter fluid are all effective solvents for removing old lubricant and contaminants. After cleaning, bearings should be completely dry before applying new lubricant to avoid dilution or contamination.
Applying Lubricant for Optimal Pinewood Derby Performance
The method of lubricant application is as important as the choice of lubricant itself. Here are some best practices based on the advice from the original forum:
- Less is More: Over-lubrication can attract dirt and increase drag. A few drops or a light coating is generally sufficient.
- Even Distribution: Ensure the lubricant reaches all critical surfaces within the bearing. Spinning the wheel after application helps distribute the lubricant evenly.
- Storage Matters: Tommy Gullett advises storing wheels standing up after lubrication to prevent the lubricant from leaking out. This is particularly relevant for low-viscosity oils like air tool oil or lighter fluid.
- Re-lubrication: The original question mentions a “one-time lube per race day” rule. For best performance, follow race regulations and consider re-lubricating between races if allowed and if performance seems to degrade.
Conclusion: Air Tool Oil as a Practical Pinewood Derby Lubricant
So, Is Air Tool Oil Good For Pinewood Derby Cars? Based on expert opinions and practical considerations, yes, air tool oil can be a viable and effective lubricant for Pinewood Derby cars. It’s not as high-tech as Krytox or as specialized as Militec-1, but it offers a practical balance of friction reduction and ease of use.
For racers looking for readily available, cost-effective lubrication, air tool oil is a solid option, especially when paired with thorough bearing cleaning using isopropyl alcohol or brake cleaner. While some may prefer higher-end lubricants for marginal gains, air tool oil stands out as a practical, accessible, and recommended choice by experienced derby participants. Ultimately, the best lubricant is one that is properly applied, keeps friction to a minimum, and helps your car achieve its maximum potential on race day. Remember to test different lubricants to see what works best for your specific car and wheels. Good luck, and may the best car win!
