Step-by-Step Guide to Changing Your 2020 Honda Foreman 520 Oil
Now that you have your tools and supplies, let’s get down to business. This detailed walkthrough will show you how to 2020 Honda Foreman 520 oil capacity changes are done safely and correctly.
Safety First: Always ensure your ATV is on a level surface, the engine is off and cool enough to handle, and the parking brake is engaged. Hot oil can cause severe burns.
- Warm Up the Engine (Briefly): Run the engine for 3-5 minutes to warm the oil. Warm oil drains more completely, carrying away more contaminants. Then shut it off and let it sit for a few minutes to allow oil to settle.
- Position the Drain Pan: Locate the engine oil drain plug. It’s typically on the bottom of the engine case. Place your drain pan directly underneath it.
- Remove the Drain Plug: Using the correct socket (often 17mm), carefully loosen and remove the drain plug. Be ready for the oil to flow out. It will be dark and potentially hot.
- Allow to Drain Completely: Let the oil drain for at least 10-15 minutes. While it’s draining, you can proceed to the oil filter.
Replacing the Filter
Your Foreman 520 likely uses a cartridge-style oil filter, located behind a cover on the engine case.
- Locate and Remove the Oil Filter Cover: This cover is usually held on by 2-3 small bolts (often 8mm or 10mm). Place your drain pan underneath again, as some residual oil will come out.
- Remove the Old Filter: Carefully pull out the old oil filter cartridge and any springs or O-rings. Note their orientation.
- Clean and Inspect: Clean the filter housing and cover. Inspect the O-rings for the cover; replace them if they appear cracked, flattened, or damaged. Many new filter kits include fresh O-rings.
- Install New Filter: Install the new oil filter cartridge, ensuring it’s oriented correctly. Lightly coat new O-rings with fresh oil before installation.
- Reinstall Filter Cover: Place the filter cover back on, ensuring the O-rings are seated properly. Tighten the bolts evenly, following the torque specifications in your owner’s manual (usually quite low, around 7-9 lb-ft).
Refilling with Fresh Oil
With the old oil drained and the new filter in place, it’s time to add the fresh stuff.
- Replace Drain Plug: Once the oil has finished draining, clean the drain plug and install a new crush washer. Reinstall the drain plug and tighten it to the specified torque (refer to your owner’s manual, typically 18-22 lb-ft). Do not overtighten!
- Add New Oil: Using your funnel, slowly pour in approximately 2.8 US Quarts (2.6 Liters) of the recommended engine oil. This is a good starting point for your 2020 Honda Foreman 520 oil capacity.
- Check the Oil Level: Reinstall the dipstick (without screwing it in if it’s a screw-in type, just rest it on the threads for an initial check). Pull it out, wipe it clean, and reinsert it. Check the level. It should be between the upper and lower marks.
- Start the Engine: Start the engine and let it idle for a minute or two. This allows the new oil to circulate and fill the filter. Check for any leaks around the drain plug or filter cover.
- Re-Check Oil Level: Shut off the engine and let it sit for a few minutes (3-5) to allow the oil to settle back into the sump. Then, re-check the oil level using the dipstick. Add small amounts of oil as needed until the level is between the marks. The final fill, with filter, should be around 3.0 US Quarts (2.8 Liters).
This careful approach ensures you hit the ideal 2020 Honda Foreman 520 oil capacity.

This section addresses typical hiccups and offers practical solutions.
Overfilling vs. Underfilling: The Dangers
Both overfilling and underfilling your engine oil can lead to serious problems:
Underfilling (Too Little Oil)
- Symptoms: Low oil pressure warning light, engine knocking or ticking sounds, overheating, reduced performance.
- Dangers: Insufficient lubrication leads to excessive friction, rapid wear of critical engine components (bearings, camshafts), and eventual engine seizure. This is particularly dangerous for an ATV pushed hard off-road.
- Solution: Immediately add the correct type of oil in small increments until the dipstick shows the proper level. Check for leaks if you consistently find your oil level low.
Overfilling (Too Much Oil)
- Symptoms: Excessive smoke from the exhaust (blue/gray), strong burning oil smell, frothy or aerated oil on the dipstick, oil leaks from seals.
- Dangers: High oil pressure can blow out seals and gaskets. The crankshaft can churn and aerate the oil, creating foam that doesn’t lubricate effectively. This leads to overheating, reduced lubrication, and potential engine damage.
- Solution: This is more critical than underfilling. You need to drain some oil immediately. Use a small pump through the dipstick tube or carefully loosen the drain plug to let a small amount out. Recheck the level repeatedly until it’s correct.
Always double-check your dipstick. It’s the ultimate arbiter of correct 2020 Honda Foreman 520 oil capacity.
Dealing with Leaks
Oil leaks are frustrating but often identifiable.
- Common Leak Sources: Drain plug (improperly tightened or bad crush washer), oil filter cover (damaged O-rings or loose bolts), valve cover gasket, crankcase seals.

Frequently Asked Questions About Your 2020 Honda Foreman 520 Oil Capacity
We get a lot of questions from our FatBoysOffroad community. Here are some of the most common ones regarding your Foreman’s oil.
How often should I change the oil in my 2020 Honda Foreman 520?
Honda generally recommends changing the engine oil and filter every 100 hours of operation or every 6 months, whichever comes first. If you ride in extremely dusty, muddy, or wet conditions, or use your ATV for heavy-duty work, consider changing it more frequently.
Can I use car oil in my Honda Foreman 520?
No, you should not use regular car oil. Your Foreman 520 has a wet clutch system, and most car oils contain friction modifiers that can cause clutch slippage and damage. Always use ATV-specific 4-stroke oil that meets JASO MA or MA2 specifications.
What happens if I don’t change my oil filter when I change the oil?
While not ideal, if you skip the filter change, the new oil will immediately begin to pick up contaminants from the old, clogged filter. This reduces the lifespan and effectiveness of the fresh oil. It’s always best practice to change the filter with every oil change.
How do I check the differential oil level?
Both the front and rear differentials have separate fill/level check bolts. Typically, you remove the fill bolt, and the oil level should be right at the bottom edge of the fill hole. If it’s low, slowly add the specified gear oil until it just begins to seep out of the fill hole. Be sure to use the correct type of gear oil.
My oil looks fine, do I still need to change it?
Yes. Oil degrades over time and with use, even if it doesn’t look visibly dirty. Additives break down, and its ability to lubricate and protect diminishes. Stick to the manufacturer’s recommended service intervals to ensure optimal protection.
Taking care of your Foreman’s oil system is one of the easiest yet most impactful ways to ensure its longevity and performance.
There you have it, folks! A complete breakdown of everything you need to know about your 2020 Honda Foreman 520 oil capacity and proper oil changes. By following these guidelines, you’re not just performing maintenance; you’re investing in the life and performance of your ATV.
