* 10W-30 is a good all-around choice for most climates. This is likely what the owner's manual recommends.
* 5W-30 is preferred in colder climates to ensure easier starting.
* 20W-50 might be suitable in extremely hot climates, but is less common for this engine.
Regarding the *kind* of oil: Use a conventional motor oil that meets the specifications listed in your owner's manual. Many modern oils meet the requirements, so you have a good variety of brands to choose from. You can also use a high-mileage oil formulated for older engines if your Camaro has significant mileage.
Capacity: The oil capacity for a 1992 Camaro 305 TBI is approximately 5 quarts. It's always a good idea to check your owner's manual for the exact amount to ensure accuracy. You should always leave enough space for the oil to expand when the engine heats up, so don't fill it to the absolute brim.
