Ruin good engines is something riders often overlook — the wrong engine oil level. Whether you overfill or underfill, both can cause serious trouble under the hood. ⚠️ What Happens If You Overfill?

Too much oil may sound like extra protection, but it’s actually a problem:

  • Foaming & Aeration: Excess oil gets whipped by moving parts, causing bubbles that reduce lubrication.

  • Increased Pressure: Overfilled oil can create excessive pressure, damaging seals and gaskets.

  • Poor Engine Performance: It can cause sluggish throttle response and overheating.

⚠️ What Happens If You Underfill?

Too little oil is a fast track to engine wear:

  • Lack of Lubrication: Metal parts grind against each other, leading to premature damage.

  • Overheating: Less oil = less heat dissipation.

  • Oil Starvation: Especially during high-speed riding or cornering, oil might not reach critical engine areas.

🧠 Pro Tip from Experience:

  • Always check your oil level using the dipstick or sight glass on level ground after the bike has cooled.

  • Refer to your owner’s manual for the correct volume and recommended grade.

  • Use only high-quality motorcycle engine oil that’s built for your riding style and climate — like DashOil.

✅ Conclusion

Your engine doesn’t need more oil or less oil — it needs the right amount of the right oil.

Riding with the wrong level is like running a marathon with the wrong shoes — it might not hurt at first, but the damage adds up. Check your oil. Ride smart. And always trust a premium oil like DashOil to protect every ride.
