How much oil does a 1992 5.7 take?
Typically about 5 quarts (approximately 4.7 liters) of engine oil with a new filter; about 4 quarts (roughly 3.8 liters) if you’re not replacing the filter. This covers the common 5.7L GM V8 family from 1992, including trucks, SUVs, and LT1-powered cars. Always confirm with the vehicle’s manual or under-hood sticker and use the correct viscosity for your climate.
In 1992 GM offered several 5.7-liter variants, from the truck-oriented small-block to the LT1 powerplant found in performance cars. While the basic capacity is broadly similar across these variants, precise figures can vary slightly by model. The general guideline remains: plan for about 5 quarts with a new filter and check the dipstick to reach the correct level. Viscosity recommendations of the era typically favored conventional 5W-30 in moderate climates, with adjustments for extreme heat or cold.
Variants and capacities
Below are the common oil capacity figures for the 1992 5.7L family, assuming a standard oil change with a new filter.
- 5 quarts (4.7 L) with filter
- 4 quarts (3.8 L) without filter
Bottom line: for a standard oil change that includes a filter, fill to about 5 quarts and then check the dipstick, adding a little oil at a time if the level sits below the full mark.
Practical tips for servicing
Use the recommended viscosity for your climate (commonly 5W-30 in many 1992 GM applications). Always install a new oil filter and, if applicable, a new drain plug gasket. Start the engine after refilling and recheck the level once it has run to operating temperature and the oil has had a moment to settle.
Summary
For a typical 1992 5.7L GM V8, plan on about 5 quarts of oil with a new filter, approximately 4 quarts if you’re not changing the filter. Verify with your specific model’s manual or sticker, and use the recommended oil viscosity for your climate. Regular checks with the dipstick will ensure you maintain the correct oil level.
