Got my first oil change at the dealer on Friday. They put Dexos1 5W30 in and i made them flush it out and put the proper Dexos2 5W30 which is called out in the diesel owners manual. I was surprised that Dexos 2 is a synthetic blend and not a full synthetic and i thought Dexos 1 was a full synthetic. Does anyone know what the difference is between these oils?
Be careful when you take your truck in that the dealer actually uses the correct oil!
