Oil is an important component for many mechanical parts, including engines, and this remains true for dirt bikes. However, there are times when oil might not be available. This can leave many riders wondering if they can get away with riding their dirt bike without oil.
You can ride your dirt bike without oil, but the absence of oil in the engine and transmission might introduce major complications to your dirt bike. It is possible to start a dirt bike and go on to ride it without oil, but not for long. Always ensure you use the right oil for your bike.
Riding your dirt bike without oil might sound like the cheaper option, but in the long run, this is not always the case. Many complications might arise from this simple act of neglect. Keep reading to understand the problems that might arise from riding your dirt bike without oil.
Why Do Dirt Bikes Need Oil?
Dirt bikes need oil for many reasons. Whether you own a two-stroke or a four-stroke engine, oil plays an important role in ensuring the engine runs smoothly. Deep knowledge of the functions of oil will allow you to make an informed decision on whether or not to ride your dirt bike without it.
The friction generated by all the moving parts in your engine leads to a rapid increase in internal temperature. There are lots of moving parts, including the pistons, the bearings that support the crankshaft, and the valve train. For all of these parts, engine oil prevents metal-on-metal contact that would greatly increase the effects of wear and tear on the engine through excess friction.
Cooling The Engine
Friction generates heat, and for your engine, heat is an unwanted byproduct. Dirt bike engines generate a lot of power and torque for the smaller size of their engines, but this large amount of power comes at a price as more stress is exerted on the engine parts.
Corresponding to the phenomenal amounts of power is an excessive amount of heat that, when unmanaged, reduces your dirt bike’s performance and in the long run leads to piston scuffing and other mechanical complications.
The oil serves to absorb the excess heat as it circulates through the various parts of the engine, and then dissipates it at the level of the sump. The temperature regulation function of the oil is crucial to prevent the metal parts from expanding beyond their limits.
Cleaning The Engine
Dirt bike motor oil contains detergents that neutralize acids and clean out impurities that may gather within the oil. Accumulation of these substances could tamper with the engine’s health. The oil takes up these substances and deposits them in the filter from which they can easily be removed.
Improving Overall Performance
Your dirt bike might work without oil, and even go without overheating if you use it right, but optimum performance can only be achieved when heat and friction are kept within acceptable ranges. All the functions of engine oil work together to improve the dirt bike’s performance which allows you to cruise at high speeds for longer without straining the engine.
Will Your Dirt Bike Start Without Oil?
Your dirt bike will start without oil. Firing up your dirt bike’s engine doesn’t involve oil. The ignition process is electrical and does not need oil. A system of electrical parts sets off the spark plug that ignites the mixture of fuel and air in the piston chambers, starting the combustion cycle.
Can You Ride Your Dirt Bike Without Any oil?
Due to the incredible engineering that goes into making durable dirt bikes, it is possible to ride your dirt bike without oil. This, however, does not mean that dirt bike-specific oil is a waste of time. Depending on how long you have been riding your dirt bike,damages incurred usually vary from unobservable to irreversible.
Riding your dirt bike for thirty minutes or so without oil might not cause a problem with your engine. Only after taking the engine apart does the real damage begin to show. There will be obvious scoring marks left on the crank and piston shafts.
A thin film of oil usually separates the fast-moving pistons from their metal casing. When oil is absent, the up and down movement of the piston grinds on the metal casing and leads to damage to the engine in general. When this damage is prolonged, metal deposits from the shaft accumulate and interfere with the internal combustion of fuel and compressed air, reducing performance.
Pushing the engine in a dirt bike without oil will immediately set off a series of funny noises which are a sure indication of the poor state of your engine. Whenever this happens, slowing down might offer momentary relief. When it is absolutely necessary, cruising at a slightly lower speed in cooler temperatures while leaving the choke valve wide open will minimize engine problems.
External temperatures have a huge part to play in the amount of damage occurring in dirt bikes without oil. Ambient temperature has a direct influence on the internal temperatures as the rate of cooling of the engine is affected by external temperatures. During cold weather, for example, less damage (at least in the short term) is expected, and the reverse is true for warm weather.
But being gentle on your bike is not a substitute for using oil. Long distances and the high internal temperature will eventually take their toll on the engine and cause problems. In the long run, going without oil in your dirt bike will do you more harm than good. The expenses saved in forfeiting the oil will be spent tenfold in carrying out repairs or replacements of your engine.
The production process for dirt bikes usually involves a series of tests that run the engine to the breaking point. If the manufacturer recommends the use of oil in your dirt bike, it is best to follow their advice as they have probably found out the effects of going without, saving you the trouble and cost of experimenting.
What Happens If You Don’t Put Enough Oil In Your Dirt Bike?
Just as it is dangerous to not have oil in your dirt bike, using too little or too much of it can cause several complications too. Many dirt bike engines usually have manufacturer specifications on the oil level required for the proper functioning of the engine. Depending on the quality of the oil or your geographical location, oil quantity requirements are bound to change.
That said, sticking by your manufacturer’s specification allows you to claim warranty benefits if you do run into problems. Low oil levels in your dirt bike may be indicated by a warning light in some models or, if you leave it too long, overheating complications such as smoke from the engine. Dipsticks may be used to identify low oil as they have indicators at the end.
If you don’t use the right kind or amount of oil in your dirt bike, you can run into a number of problems.
You might be cruising on the sand with your dirt bike when you notice a sudden scuffing sound from your engine. If you do, after slowing down, it is important to check for engine damage. A simple way to do this is by putting your dirt bike into fifth gear and then rocking the motorcycle back and forth, before turning it on.
A dirt bike suffering from engine seizing will produce loud noises or the scuffing sound will be more pronounced. When this happens, low oil is usually the culprit. Further use of your dirt bike will therefore have a detrimental effect on your engine.
The scuffing sound originates from the piston coming into contact with its metal shaft. As we mentioned earlier, insufficient oil leads to thinning of the film separating the piston from the shaft. Extremely high internal temperatures lead to this film disappearing, which leads to the grinding of the metal, producing irritating sounds.
Wear, Tear, And A Burning Smell
Wear and tear damage is obvious when using your dirt bike without oil. For metallic parts turning hundreds of times per minute, contact results in grinding. The sudden smell of burning metal will immediately point to a mechanical problem. This, along with a bit of smoke and noise coming from the engine, is enough to alert you that your engine is in dire need of oil.
Which Oil Is Right For Your Dirt Bike?
In dirt bikes, oil serves to lubricate the engine and transmission along with performing other diverse functions. The high internal temperatures within the dirt bike’s powerful engine present engine oil with an uphill task. In addition to the temperature, the unbelievable amount of pressure generated during internal combustion affects the properties of the oil.
The oil acts as a lubricant under extreme conditions and still manages to maintain the right consistency to allow the metal plates in the clutch to function properly. But in order for your engine’s oil to do all of this, you need to choose the right oil for your dirt bike.
There are several factors to consider before settling on the perfect oil for your dirt bike. Many of these considerations have nothing to do with the oil, but everything to do with the dirt bike itself. Different dirt bikes have varying functions and generate different amounts of power and torque. Before choosing the right oil, it is important to familiarize yourself with the bike.
Your Geographical Location
Different locations have different climatic conditions. Some areas are warmer than others and ambient temperatures have a major effect on the condition of the engine. Areas that experience large temperature ranges require more resilient oils. To prevent regular, costly oil replacement, the more viscous synthetic oil is a good choice as it handles the temperature and pressure fluctuations better.
Your Dirt Bike Riding Habits
Dirt bikes are built for extreme use. Coursing through sand dunes or muddy trails is part of the daily routine for a dirt bike owner. Those that enjoy their dirt bikes in a more relaxed way, riding only intermittently, are likely to exert less strain on their engine and oil,whereas those who push their dirt bikes to the limit are likely to do the opposite.
Depending on what type of dirt bike rider you are, the perfect oil for you is the one that functions exceptionally while falling within your budget. High-performance dirt bike oil is expensive, but it’s a suitable option for those that do a lot of riding. Cheaper but less durable oil is a better option for the more casual rider.
The Type Of Dirt Bike You Own
Regardless of the environment and bike riding habits, choosing the right type of oil for your dirt bike usually depends on the type of bike you have. The year of manufacture is usually an important factor to consider as well. Older models usually lack their owner’s manual, which means that you’ll need to do your research on what works best for your engine.
For these older models, or models for which you don’t have the manual and can’t find instructions online, settling on the perfect oil can only be achieved through a series of trial-and-error processes. Before beginning the trial-and-error process, you should check the oil cap of the dirt bike as some manufacturers usually have instructions beneath the cap.
For newer models, finding the perfect oil is as simple as opening the owner’s manual and reading the instructions. Manufacturer preference for oil is usually obtained after vigorous testing, which offers reliable insight on what density of engine oil to use, and how best to carry out routine maintenance.
Synthetic, Mineral-Based, Or Semi-Synthetic Oil
Conventional oil, also known as mineral-based oil, remains the cheaper alternative and most widely preferred. However, this inexpensive motor oil has its pitfalls. The oil is made of crude oil and therefore contains mineral deposits.
The purity of your oil is a very important factor to consider as impurities can accumulate in the engine, resulting in other complications. Mineral-based oil is not a bad option, but neither is it the best for your dirt bike.
Semi-synthetic oil is a hybrid between mineral-based oil and modern synthetic oil. It has benefited from both of its substituent components. However, it also has some of the disadvantages of normal mineral-based oil. In terms of pricing and performance, it is midway between conventional oil and synthetic oil.
Synthetic oil is the modern version of engine oil and it’s a product of years of technological advancements. It is the best oil for your dirt bike, but it is expensive. Some synthetic oil is made of natural gas instead of crude oil, which enables it to maintain a higher level of purity. Synthetic oil can also make your dirt bike easier to start in colder temperatures.
The significantly higher price of synthetic oil is compensated by its durability. Synthetic oil lacks the mineral deposits in conventional oil and so there are minimal resulting impurities within it that could damage the engine, meaning it can last longer before needing replaced.
Normal Car Oil As Dirt Bike Oil
It is tempting to use normal car oil in your dirt bike, but keeping in mind the abuse your oil is put through by the shorter gears and increased off-road activity of your dirt bike, this might not be a good idea.
Dirt bike-specific oil has numerous additives designed specifically for your dirt bike. Choosing oil that has the correct viscosity, best durability, and overall highest value for your money, will save you money in the long run.
Riding your dirt bike without oil is highly discouraged. Your engine must maintain a steady supply of fresh oil to prevent any mechanical damage or accumulation of harmful substances within your engine. Synthetic dirt bike oil is the best option for your dirt bike as it provides better performance and lasts longer before needing changed.
