New to me Express 2500...Time to change oil! Help!
So, I checked the OM. It says nothing about must use Synth Oil. The guy that sold it to me said they followed the Om recommendations. So I am assuming using the 5-30 regular Valvoline oil for my 6.0, V8 in a 2008 Express 2500 would be ok? I have 60k miles on it. The reason asking is that all the vids I have watched on the oil changes are throwing in synthetic or a quart of it, for good measure I guess. Anyone have any advice?

My 2013 requires the new top level standard Dexos. most top brand oils are dexos rated now, but in case you are not sure check. GM now says you should use that dexos rated oil in all your gm vehicles old or new.
As I am always looking for a deal. I noticed that Wal Mart sells the Valvoline semi synthetic Maxx life oil. Its is the cheapest option for me, and it is Dexos rated. Also, the actual gm dexos oil you get at the dealer is semi synthetic, not full synthetic....so its a good match.

General Motors vehicles built in 2011 and later, required the use of dexos™ licensed engine oil. My Express is 2008 so I guess I am good with Non Dexos. Looking to go with a blend if possible ...just dont want to cause leaks after using regular for 60K

They did go on the say that you should run Dexos in all gm vehicles since its a better oil with a better base. However yes you could just run anything. I like high mileage oil because of the extra zddp which is an antiwear additive. Quaker state Defy, and Maxx Life from Valvoline are semi synthetic high mileage oils. You will have to shop around.

I have been using Peak full synthetic oil for years. Didn't even realize it is Dexos until now. Anywho, we use it in all of our trucks/equipment and buy several cases a year on Amazon. Its priced right.
