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).
Your window enters the onset band.
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
