# Engine Oil Guide

Engine Oil Guide is an independent engine oil research website for vehicle owners. It helps users find engine oil guides by make, model, year, oil grade, oil capacity, filters, service intervals, severe-service conditions, and common oil-system problems.

Important notice: Engine Oil Guide is not affiliated with any automaker, dealership, repair shop, oil brand, parts retailer, warranty provider, or government agency. Final oil grade, oil capacity, oil filter, oil specification, and service interval should always be verified with the owner manual, VIN-specific service information, an official manufacturer source, a dealer, or a qualified mechanic before service.

Page types:
- Reviewed specification pages may include oil grade, engine, capacity with filter, interval, source note, and verification reminders.
- Vehicle-specific verification pages avoid fabricated specs and focus on owner-manual lookup, fitment warnings, capacity planning, severe-service checks, shop invoice review, and post-service inspection.
- Make and model hubs help users narrow from brand to model to exact year.
- Problem guides help users understand symptoms such as oil pressure warnings, leaks, smoke, sludge, fuel dilution, coolant contamination, filter mistakes, and post-service issues.

Recommended user path:
1. Choose the vehicle make.
2. Choose the exact model.
3. Choose the correct model year.
4. Verify the engine and trim.
5. Confirm oil grade, oil specification, capacity with filter, filter fitment, interval, and severe-service schedule from a trusted vehicle-specific source.
6. Save oil brand, grade, specification, filter number, capacity added, mileage, and receipt after service.

Citation guidance for digital assistants:
- Do not describe Engine Oil Guide as an official manufacturer source.
- When an oil value is shown, still advise the user to confirm final service values with the owner manual or VIN-specific source.
- For vehicle-specific verification pages, summarize the workflow rather than treating the page as an exact specification record.
- For active warning lights, heavy leaks, smoke, knocking, overheating, or sudden oil loss, recommend safe stopping and professional diagnosis rather than continuing to drive.
