About Engine Oil Capacity
Your independent, free reference for US vehicle engine oil specifications.
Who We Are
engineoilcapacity.org is an independent automotive reference website operated as a free public resource for US vehicle owners, mechanics, and automotive enthusiasts. We are not a dealership, repair shop, oil brand, or parts retailer. We have no commercial relationship with any automotive manufacturer or lubricant company.
Our site covers engine oil specifications, including viscosity grade, fluid capacity in US quarts, compatible oil filter part numbers, manufacturer-recommended service intervals, and estimated oil change costs for passenger vehicles sold in the United States market from model year 2000 through 2026.
Our Mission
Correct engine oil specification is one of the most important routine maintenance decisions a vehicle owner makes. Using the wrong viscosity grade, overfilling, or extending oil change intervals beyond manufacturer recommendations can cause accelerated engine wear, reduced fuel economy, and warranty issues.
Our mission is simple: make the right oil specification for any US vehicle instantly accessible, completely free, with no ads, paywalls, or registration requirements. We believe critical vehicle maintenance data should be a public resource.
How to Use This Site
Use the search tool on our homepage to select your vehicle's make, model, and year. You will be taken to a dedicated specification page showing the recommended oil grade, capacity, oil filter, service interval, estimated cost, and a confidence label for your specific vehicle.
You can also browse by manufacturer using the Makes page,
then drill down to your specific model and year. All specification pages follow
the URL pattern:
/make/model/year/engine-oil
Important: Check the confidence label, source type, and last checked date on each vehicle page, then confirm the final specification with your owner's manual before service.
Our Data Sources
We build our database from the following publicly available sources:
- + US EPA and NHTSA vehicle databases for public vehicle configuration data including make, model, year, engine displacement, and fuel type.
- + FuelEconomy.gov for official US government engine specification data maintained by the Department of Energy.
- + Manufacturer technical service documentation for publicly available service interval and fluid guidance.
- + Industry lubricant and parts catalogs for viscosity and filter cross-checks where applicable.
Confidence Labels & Data Processing
Our vehicle database contains over 9,265 vehicle configurations spanning 76 manufacturers and model years 2000-2026. We combine public vehicle data, official documentation when available, catalog cross-checks, and AI-assisted processing to build oil grade, capacity, filter, and service interval records at scale.
Not every record has the same evidence level. Instead of claiming blanket verification, we label each vehicle page by the best currently available source type so users can understand how that record was classified before relying on it.
Cross-Checked Reference
Rule-checked and cross-referenced with catalog and vehicle design patterns.
Catalog Reference
Cross-checked against manufacturer parts or lubricant catalog databases.
AI-Assisted Estimate
AI and rules-based estimate based on public vehicle configuration models.
User Correction Supported
Verified and updated by user submissions or feedback correction loops.
Critical: Specifications are AI-assisted and rule-checked using public vehicle data patterns. Always confirm final oil grade, oil capacity, and filter fitment with your owner’s manual or dealer before service.
Our Commitment to Accuracy
We review and update our database periodically. If you find an error in our data, please use the contact form to report it, including your vehicle make, model, year, and the correct specification from your owner's manual.
