Frequently Asked Questions
Can I just use the same oil I put in my car?
You should avoid doing this unless your manual specifically says it is safe. Most cars use friction modifiers to increase fuel economy, which will cause your ATV's wet clutch to fail prematurely. Always stick to oils designed specifically for powersports applications.
How often should I change my ATV oil?
A good rule of thumb is to change it every 50 to 100 hours of operation. If you mostly ride in deep mud or dusty conditions, you should shorten that interval to 30 hours to clear out contaminants. Dirty oil is like sandpaper inside your engine, so do not skip this chore.
Does the brand of oil actually matter?
Consistency is more important than the specific label on the bottle. As long as the oil meets the viscosity requirements and the JASO standards listed in your manual, you are in good shape. Pick a reputable brand and stick with it so your engine knows what to expect.
What happens if I mix two different brands of oil?
It is not ideal, but it will not destroy your engine in an emergency. If you are low on oil in the middle of a trail, adding a different brand is much safer than running low oil levels. Just make sure the weights match and change the oil properly as soon as you get home.
Is more expensive oil always better?
Higher price points usually indicate full synthetic formulations with advanced additives. These oils handle extreme heat and long-term storage better than cheaper options. While you do not need the most expensive bottle on the shelf, avoid the bargain bin options that lack industry certifications.
