How many quarts of oil does a 2002 5.3 hold?
About 5 quarts of engine oil, including the new filter, is the standard capacity for the 2002 5.3-liter V8.
The 2002 5.3L V8 (GM Vortec LM7) uses 5 quarts of oil with the filter changed. If you drain the oil completely and replace the filter, you can expect to add roughly five quarts as part of a typical oil-change procedure. Variations may occur due to filter size or slight differences in the pan fill during servicing, so always verify the level with the dipstick after refilling.
What the official spec says
General Motors’ documentation for the 2002 Silverado/Sierra and associated 5.3L V8 engines lists the oil capacity as 5 quarts (with filter). This figure is widely echoed by the owner manuals and service guides for that model year.
- 5 quarts with a new oil filter (the standard capacity for the 2002 5.3L V8).
- About 4.5 quarts if you drain only the pan and do not replace the filter—note that this is not typical practice for a full oil change.
In practice, most oil-change procedures target adding around 5 quarts, then checking the level with the dipstick and topping up as needed to reach the full range on the stick.
Why the capacity matters
Knowing the correct oil capacity helps prevent overfilling, which can cause foaming and pressure issues, and underfilling, which can lead to insufficient lubrication. Always verify the final oil level after a change and adjust as necessary.
Practical steps for an oil change on a 2002 5.3
Prepare the correct oil grade (typically 5W-30 for many climates), a new filter, a drain pan, and basic hand tools. After draining old oil and replacing the filter, add about 5 quarts of oil, run the engine briefly, turn it off, wait a minute, and recheck the dipstick. Add small amounts if needed to bring the level to the full mark.
Tips for accurate checking
Check the oil level on a level surface with the engine off and at its operating temperature (a warm engine shows a more accurate level). If you recently changed the filter, ensure the filter is seated properly and that you’re using the correct filter for the 5.3L V8.
Summary
The 2002 5.3-liter V8 generally requires 5 quarts of oil with a new filter. Always verify the exact level with the dipstick after an oil change, and adjust for any minor variation based on filter type or servicing practices.
