As you hopefully won’t learn the hard way, not all side-by-side oils are created equal. Using the wrong oil can not only void your warranty, but it can also damage your engine. A basic petroleum oil is going to do the trick for a stock engine subject to moderate demands, but synthetic oils are where it’s at because they can handle tougher temperatures without breaking down.
First, let’s talk viscosity. Basically, viscosity just expresses how readily a liquid can flow. In the UTV world, this is a temp-specific value that is key to your performance. Your manufacturer should recommend a viscosity level according to usage, so always keep this front of your mind when shopping!
Oil filters are your engine's kidney. They remove contamination before it causes wear. Filter quality varies dramatically between brands. OEM filters are designed specifically for your engine and guaranteed to fit and function correctly.
Premium aftermarket filters from popular brands like K&N or Mobil 1 will generally go beyond your OEM specs while saving a bit of money, but when you get into the “super budget” category, you need to be really careful about cheap filter material and poor anti-drainback valves (which means dry starts!).
Beyond your standard oil change, additives claim to boost your performance or protection, like friction modifiers. Quality products backed by actual testing can, in fact, provide measurable benefits, but there are plenty of not-so-savory actors in this space whose claims go far beyond what their side-by-side performance additives do.
Fuel additives can clean your injectors or boost octane.
Stabilizers, for example, prevent fuel degradation during storage. These have legitimate uses but aren't necessary for normal operation with fresh pump gas and stock tuning.
Coolant and brake fluid eventually need changing, too. Change coolant every 2-3 years or when contaminated, brake fluid annually or whenever it shows signs of water absorption (goes dark or mushy feeling).
Transmission and differential fluids follow similar schedules to engine oil. Consult your manual for specific intervals and specifications for all fluids.
Can I just use automotive oil?
This all comes down to your UTV. Sometimes, yes (depends on wet vs dry clutch). Check your manual!
What are some signs I need an oil change?
First and foremost, your manufacturer will provide guidance on this, but if you’re checking your oil regularly like you should be (just sayin!), look for black color or metal shavings. If not, you can ride until you hit that recommended mileage.
Do I really need to change my air filter that often?
Yes! Whether you’re in dusty conditions or not, you will lose more power than you think with a clogged filter.
