What kind of oil does a 5.7 Chevy take?

A quick answer: most Chevrolet models with the 5.7-liter V8 (the Vortec 5700) require Dexos1 Gen 1 approved oil, typically 5W-30, and about 6 quarts with a new filter. Always verify the exact specification for your year and model in the owner’s manual or on the under-hood oil sticker.


Understanding the oil requirements for the 5.7 Chevy


The 5.7L Vortec engine has lived through multiple model years and GM specifications. While Dexos1 Gen 1 is the common standard for many 5.7L applications, the exact grade and approval can vary by year and vehicle. Checking the owner’s manual or the service label under the hood provides the definitive guidance for your particular truck, SUV, or van.


What oil and grade are generally recommended


The following guidelines cover the typical requirements you’ll see for the 5.7L Vortec in most GM trucks and SUVs. Use the information as a starting point, then confirm with your specific vehicle.



  • Dexos1 Gen 1 certified motor oil

  • Viscosity commonly 5W-30

  • Oil can be synthetic-blend or full synthetic, both meeting Dexos1 Gen 1 standards

  • Oil capacity is about 6 quarts (5.7 liters) with the filter installed

  • Oil should meet API SN/SM or newer specifications in addition to Dexos1 Gen 1


Concluding note: While these specs cover the typical 5.7L setups, the exact requirement depends on your model year and region. Always verify the specification for your vehicle.


Practical guidance for choosing and changing the oil


To help you navigate selecting the right oil and completing a change, follow these practical steps. The list below summarizes a standard approach used by many owners and service shops for the 5.7L Vortec.



  1. Consult the owner's manual or the under-hood sticker to confirm the exact Dexos specification and oil grade required for your year and model.

  2. Select a Dexos1 Gen 1 certified oil, with 5W-30 as the most common grade for this engine.

  3. Choose a synthetic-blend or full synthetic oil based on climate, driving conditions, and manufacturer guidance.

  4. Plan for about 6 quarts of oil and a new oil filter when performing a change.

  5. Dispose of used oil properly and reset any oil-life monitor if your vehicle is equipped with one.


Concluding note: Using the correct Dexos1 Gen 1 oil at the right viscosity and capacity helps protect the engine, maintain performance, and support emissions compliance.


Model-year considerations and tips


Different configurations and settings


The 5.7L Vortec has appeared in various GM vehicles over a wide span, including pickups and SUVs. While the general guidance above applies to many of these models, some years or trims may reference a slightly different specification. Always rely on the official manual for your exact vehicle.


Dexos1 Gen 1 vs. other Dexos specifications


Dexos1 Gen 1 is the long-standing standard for many GM gasoline engines, including the 5.7L in many mid-2000s to early-2010s models. Some newer GM engines use Dexos1 Gen 2 or Dexos2 specifications. If a service label or manual notes Dexos2 for your vehicle, follow that instruction; otherwise, Dexos1 Gen 1 with 5W-30 remains the typical choice for most 5.7L applications.


Summary


For the Chevrolet 5.7L V8, the typical recommendation is Dexos1 Gen 1 approved oil, commonly 5W-30, in a synthetic-blend or full synthetic form, with an oil capacity of about 6 quarts including the filter. Always verify the exact specification for your year and model in the owner’s manual or on the under-hood label. Regular oil changes with the correct spec help protect the engine and maintain performance.
