Severe-Service “Reserve” Engine Protection

Many enthusiasts modify their ATVs or UTVs with roof and door panels, skid plates, a winch, a plow or other accessories that add weight and increase the severity of operation. Aggressive riding and tackling tough terrain place additional stress on the engine. Increased heat generated during severe-duty operation causes oils designed for standard service to break down sooner, increasing the risk for wear. AMSOIL Synthetic ATV/UTV 10W-40 Motor Oil’s synthetic technology delivers reserve protection against heat. It provides reliable wear protection and aids in cooling shrouded engines. Be sure to check our blogs out on the subject!!

Of course we can write all day about this reserve protection but it also results in a increase in performance you can feel!!

ATV/UTV Maintenance: 7 Tips to Maximize Your Machine’s Life

4-Wheeler’s aren’t cheap. And neither should be your approach to maintenance if you want your machine to deliver peak performance and last for years.

Fortunately, ATV and UTV maintenance boils down to a handful of relatively simple practices any do-it-yourselfer with basic tools can accomplish.

Here are our top 7 ATV/UTV maintenance tips.

Check/change the oil

Let’s dispense with the obvious: Check your motor oil frequently and change it according to the recommendations in the owner’s manual.

Changing the oil and filter is especially important in ATVs and UTVs used for hard work or aggressive riding.

The added stress we heap on our machines increases heat. And heat causes oils formulated for standard service to lose viscosity (become thinner). Thinner oil than what your engine is designed to use can fail to develop an oil film of adequate thickness or strength to protect against wear.

Extreme heat also invites sludge and performance-robbing deposits. Sludge can clog oil passages and starve the engine of oil, while deposits can cause power loss due to sticking piston rings.

Changing oil on your 4-Wheeler is the best defense against engine wear and power loss. Be sure to upgrade to a good synthetic oil, too.

Synthetics don’t contain the impurities inherent to conventional lubricants, meaning they deliver better performance and last longer. Their naturally tough base oils resist extreme heat and maintain a strong protective film better than conventional products.

And don’t balk at the higher price, either.

Think of synthetic oil as just another performance upgrade for your machine. You don’t think twice about spending a few hundred dollars on a snowplow or beefier winch. The few extra dollars spent on better oil is nothing by comparison – and it’ll help your machine perform better and last longer.

Change the differential fluid

It’s the same story inside the front and rear differentials.

The extra weight and stress of hard work and performance riding concentrate intense pressure on gears. The lubricant coats the gear teeth during operation, guarding against metal-to-metal contact and wear. The added stress, combined with high heat, can break the fluid film and literally squeeze the lubricant from between the gears, leading to wear.

Change differential fluid according to the recommendations in the owner’s manual. And, like motor oil, upgrade to a good synthetic. It’ll provide improved film strength despite intense pressures to protect gears and bearings in the toughest conditions, helping your machine last for years.

Anyone who’s changed differential fluid knows it can be a hassle: tough-to-reach fill holes, bloody knuckles and gear lube spilled everywhere.

The AMSOIL easy-pack reduces mess, hassle and frustration when changing gear lube. It makes ATV/UTV maintenance much easier, as the video shows.

Traditionally, enthusiasts use a gear-lube pump in these scenarios. But that’s one more tool to buy. Plus, much of the gear lube is wasted inside the pump and it makes a mess during storage.

Its flexible design allows you to access fill holes in tight spaces and around obstacles that prevent use of the rigid conical bottles common to the gear-lube market.

Check/change air filter

An engine needs three things to run: fuel, spark and air. Most of us forget about air since we don’t have to pay for it.

But a dirty or clogged air filter can choke off airflow and reduce performance or cause the engine to quit completely.

Here’s an analogy to illustrate: Go outside and run around your house. If you’re in decent shape, it shouldn’t be that difficult.

Now, run around your house while breathing through a straw. Restricting airflow into your lungs makes it much more difficult.

The same principle applies inside your engine. A dirty air filter restricts airflow and reduces engine performance. It also allows debris to enter the engine, which can lead to wear.

Check your owner’s manual for recommendations on how often to change the air filter. Check the filter periodically and change it if it’s excessively dirty.

Pro Tip: Ensure the air filter is firmly seated and correctly installed. If not, the engine will ingest dirt, which acts like sandpaper and scours the cylinders, rings and bearings.

Finally, consider using a pre-filter to extend filter life. A pre-filter is essentially a mesh bag that fastens over the air filter. It captures large contaminants and keeps them from lodging in the air filter, extending its life.

Stabilize the fuel

Gas can break down in as little as 30 days. When it does, varnish forms inside the carburetor, which clogs the tiny fuel passages. Eventually, varnish will prevent adequate fuel-flow and keep you machine from starting.

For best performance, add stabilizer to every tank of fuel. If you know you’re going to burn through a tank quickly, like during a day-long ride, you can skip the stabilizer. But many enthusiasts run on the same tank of fuel for months.

Personally, I use my ATV primarily for hauling firewood around my property, meaning it runs in fits and starts. It’s common to use the same tank of fuel for several months.

Stabilizer inhibits oxidization that occurs when fuel sits for long periods. It helps prevent varnish to keep the carburetor clean and the fuel flowing properly.

Pro Tip: Most gasoline contains ethanol, which can corrode carburetor components and damage rubber gaskets and fuel lines. For best performance use 91-octane, ethanol-free gas. If you use 87-octane gas that contains ethanol, treat it with a fuel additive designed to prevent ethanol problems, like AMSOIL Quickshot.

Wash periodically

True, your ATV or UTV is meant to get dirty. But it shouldn’t stay dirty.

Wash off mud and debris, especially after a particularly messy (i.e. fun) ride.

Caked mud and dirt traps moisture, which can hasten rust formation on metal components. It can also pack in around the engine or differentials, which reduces heat-transfer. This causes the temperature to increase, which speeds the rate at which the lubricant oxidizes, or breaks down.

Mud, leaves and other debris packed against the radiator can also cause the engine to run hotter, reducing efficiency.

Take a pressure washer to your machine if you can. Also, consider using an undercoat product that eases cleanup, such as AMSOIL Mudslinger. It provides a protective layer of armor against mud, dirt and snow, making cleanup with a low-pressure garden hose easy.

Pro Tip: After washing, run your machine so engine heat can dry any water that entered the exhaust or the areas around the spark plug boots and coil.

Check coolant level and condition

Here’s another easily overlooked ATV/UTV maintenance practice. It doesn’t help that the coolant reservoir is often buried where you can’t readily see it.

Check the coolant level in the radiator. Inspect fluid condition. If it contains sludge or slime, it’s time for a change. Putting it off can result in debris clogging the narrow coolant passages in the engine and preventing optimum cooling. This can lead to the engine overheating. Engine parts expand when they grow hot, which can result in scuffing and wear.

Even better my favorite AMSOIL product for all vehicles – the Coolant Boost. Keeps the unit operating more efficiently and works with your antifreeze for better warm ups in the winter time.

While you’re at it, check the coolant hoses for abrasions or wear. Replace them as needed before they break and leave you stranded.

Inspect tires, CV boots, etc.

Finally, walk around your machine once a month or so and check the following:

  • Tire pressure and condition
  • CV boots for cuts or leaks
  • Brake line condition
  • Lights
  • Brake fluid level

This can help you spot any issues before they turn into expensive problems. It’s also a good idea to lubricate any pivot points and linkage with a good spray lubricant, like AMSOIL MP. Doing so is a simple way to ensure your machine operates as designed for the long haul.
