How Long Can You Drive Without an Oil Cap? 

Do you know the significance of a 21-88 Dexter oil cap? A lot of drivers fail to understand the importance of oil caps. At first glance, they are a minor feature found within the engine of a vehicle. However, they have a big role in the operation of a vehicle. While you can technically drive without an oil cap, it is not recommended in any way. Driving your vehicle without an oil cap could spell disaster for your engine.  

So, how long can you really drive without an oil cap and what do you need to know about them? 


How Far Can You Travel Without an Oil Cap? 

In theory, you can drive a car without an oil cap. However, it is not recommended and could cause the engine to seize or experience a blowout. Remember, oil can spill out of its container during the drive and can cover the various components of the engine. It could lead to a fire, among many other issues. Of course, if you plan to drive a car without a proper oil cap, you should have a temporary one in place. 

For instance, a temporary could be used to protect the engine until you buy a new cap. It isn’t the long-term solution, however, and you need to get a replacement as soon as you can.  

Can You Drive Without a Cap or Temporary Filler? 

Yes and no. While the answer might seem a bit cloudy, the truth is that it is. While you can technically drive a vehicle with no oil cap and no temporary filler, it isn’t advisable. You shouldn’t be tempted or risk driving without an oil cap as the engine could be damaged beyond repair. It happens all too often but can be incredibly dangerous to do so. You need to get a new 21-88 Dexter oil cap as soon as you can. The risk is too great.  

What Risks Come from Driving Without an Oil Cap? 

It isn’t safe to drive without an oil cap because the engine is compromised. Remember, an oil cap acts as a seal and protects the oil and engine alike. Oil can’t spill out into the engine and dirt and debris cannot contaminate the oil either. That’s just two major reasons why you should never drive without an oil cap.  

Will Low Oil Pressure Be Caused by a Missing Oil Cap? 

Typically, your vehicle will experience low oil pressure with a missing oil cap. This happens because the oil isn’t restricted to the usual compartment. Instead, it may spill out which causes the low pressure. When you have low oil pressure, it means you’ll experience poor fuel economy, a drop in performance, and stalling. That’s why you should replace a missing oil cap.  

Don’t Take the Risk of Driving Without an Oil Cap 

Maintaining race car trailer accessories, like a 21-88 Dexter oil cap, is crucial for vehicle safety and performance. Oil caps may seem minor but play a significant role in sealing and protecting your engine. Driving without an oil cap can lead to severe engine damage, oil spills, and even fires. It is essential to replace any missing oil caps promptly to avoid low oil pressure, poor fuel economy, and potential engine failure. Ensure your race car trailer is always equipped with the right accessories to keep it running smoothly and safely.…

Can I Change from Oil Bath to Grease on my Hotshot Trailer?

The key reason individuals choose an Oil Bath Hub over a Grease Hub is that an oil bath hub has a less complicated maintenance schedule than a grease hub. It is suggested to inspect as well as re-grease the seals and tire bearings every 12,000 miles. With oil bath hubs, 21-88 Dexter mentions checking periodically and refilling when required.

What Are the Advantages of Grease Over Oil?

Although there are several situations where oil is the best option, bearing lubrication with grease is the desired option for over 80 percent of our featured consumers. Several select greases as it doesn’t filter out like oil. Worn seals won’t leak as simply with grease. Oil leaks can damage other components, for example – the brakes.

The Grease Can Last Longer

Grease will stay in place longer than oil due to its higher viscosity. Grease is the desired choice whether longer life is needed. The grease consists of approximately 85 percent synthetic oil or mineral oil with thickeners making up the remainder of the grease volume.

What Are the Advantages of Oil Over Grease?

The most typical reason to use oil for your trailer axle bearings is for long-distance driving. Carrying heavy loads or over long distances, your wheel bearings will reach a high temperature. Since the oil can flow more independently, it may transmit heat away from the working surfaces of the bearings. This creates oil lubricants more effective in these high-temperature and high-speed conditions.

Shaft Bearing Maintenance

The oil can be altered without much hardware disassembly. Grease repackaging is more labor intensive, increasing costs as well as downtime. The volume of oil is simpler to measure likened to grease. Sight glass or level gauges let you monitor the levels of oil. Grease is not so simple to review. This may be an issue, as under or over-greasing can cause the failure of the bearing. Use a reliable 21-88 Dexter to ensure everything run well.

Re-Greasing vs. Oil Change

Most mechanics can suggest that for oil bath hubs you don’t require to modify the oil at any certain interval. If there are no leaks, it must be left alone. On the other hand, if the oil looks milky, it must be modified.

The re-greasing intervals that will always deliver the ideal amount of oil to the bearings can’t constantly be precisely expected. We see that a good interval depends primarily on the operating temperature, the number of hours daily, as well as the speed and size of the bearings.

Certain trailers need to add grease to the bearings every 15 days, some once a month, and even some every 3 months. In applications like this, it is usually useful to thoroughly flush the bearings once a year, repack them with fresh grease, as well as continue with the established re-greasing schedule. 


Proper maintenance of race car trailer accessories, like the 21-88 Dexter Hub, is crucial for performance and longevity. Choosing between oil bath and grease hubs depends on your needs. Oil bath hubs are easier to maintain and ideal for long-distance, high-temperature conditions. Grease hubs offer better sealing and durability, preferred for heavy-duty use.

Grease prevents leakage and lasts longer, while oil effectively dissipates heat. Regular maintenance, whether re-greasing or changing oil, is essential to keep your trailer’s bearings and components running smoothly.

Using high-quality accessories like the 21-88 Dexter Hub ensures efficiency and reduces downtime. Make an informed decision based on your trailer’s use and follow a consistent maintenance schedule to keep it in top condition.…
