All 1 Known Issues
On the 2022-2025 Acura MDX, the 3.0L twin-turbo V6 in the MDX Type S experiences oil dilution from unburned fuel entering the crankcase during short trips and cold-weather driving. The direct injection system oversupplies fuel during cold starts, and the fuel washes past the piston rings into the oil, raising the oil level and reducing lubrication effectiveness.
Common Symptoms
- Oil level rises above the full mark on dipstick
- Gasoline smell in engine oil
- Oil appears thin and fuel-like on dipstick
- Slightly rough cold start idle
- Oil change interval warning earlier than expected
How to Fix
Allow the engine to reach full operating temperature on every drive — avoid frequent short trips under 10 minutes. Check oil level regularly using the dipstick (not just the electronic gauge). Change oil at 5,000 miles rather than the standard 7,500-mile interval during winter months. Honda/Acura may issue a PCM update to adjust cold-start fueling strategy.

Parts and tips from 520+ owners who fixed this issue
- NoteIf you primarily drive short trips in cold weather, cut your oil change interval to 5,000 miles. The diluted oil loses viscosity and can accelerate bearing wear on the turbo V6. Check the dipstick monthly.
