AMSOIL’s synthetic motor oils are designed to meet or surpass the most recent industry specifications, including ILSAC GF-6, API SP, GM dexos1 Gen 2 and Gen 3, as well as dexos R. These oils are suitable for use in engines requiring any of these standards. Notably, the AMSOIL Signature Series provides superior performance, exceeding the GM dexos1 Gen 2 specification.

How to Check Your Engine Oil

 

It’s essential to check your Silverado Trail Boss’s oil regularly—like every 300-400 miles or before long trips. To get an accurate reading, park the vehicle on level ground. Check the engine oil level after the engine has been off for at least two hours. Checking the engine oil level on steep grades or too soon after engine shutoff can result in incorrect readings. Accuracy improves when checking a cold engine before starting.

If you cannot wait two hours, the engine must be off for at least 15 minutes if the engine is warm, or at least 30 minutes if the engine is really hot. Pull out the dipstick, wipe it with a clean paper towel or rag, then push it back in completely. Remove it again, with the tip down, and inspect the level. If the oil is below the cross-hatched area at the tip of the dipstick and the engine has been off for at least 15 minutes, add a quart of the oil recommended above in this article and check the level again. Make sure not to add too much oil as this can damage the engine.

By following these steps, you can be sure your Silverado Trail Boss is topped off with just the right amount of oil to keep your engine purring and running like a well-oiled machine.

Proper Disposal of Used Oil

 

Used engine oil is harmful to health and the environment. Always avoid skin contact, and wash exposed skin well if contact occurs. Recycle used oil by taking it to a recycling facility. Never dispose improperly in the trash, sewers, or water bodies.
