Fuel/oil dilution pattern
powertrain.engine.fuel-dilution
Fifth-generation Honda CR-V model-year evidence; engine/configuration scope remains disclosed rather than inferred from an untrimmed complaint.
- Symptom
- Gasoline odor and an oil level above full after use
- Why it matters
- Fuel-diluted oil may reduce lubrication and contribute to engine damage; reports also describe fuel odor in the cabin.
Observed complaint mileage band; not an incidence probability
Reported onset roughly 1,200–40,000 mi (median 5,000 mi).
Onset window is behind this candidate — verify whether the issue already occurred/was repaired.
Based on 511 usable reports (812 censored). Complaint mileage is an observed report band, not a population incidence estimate.
What to inspect
- Check the oil level on a level surface and smell the dipstick for fuel odor
- Review oil-change and dealer diagnostic records
Pro check: Independent pre-purchase inspection.
Mitigation
- Verify current manufacturer guidance and maintain documented oil changes
- Have a qualified technician inspect persistent fuel odor or rising oil level
