I was wondering how many quarts of oil and which oil weight I need for a 2011 Chevy Silverado WT with the 4.3L V6... I downloaded the owners manual online, but it did not specify the amount of oil needed for an oil change. I did find that it requires dexos certified oil. I'm not quite familiar with dexos oils. Can I use synthetic oil?

Any help would be greatly appreciated. Thanks!

 

These should help:

And I ALWAYS use synthetic.

 

Thank you very much! Any harm in putting in 5 quarts even though it calls for 4.5?

B-u-u-t, maybe that's just because I'm old ….
