When should I do the first oil change on a new 6.0 liter gmc van? It has the computer which tells you when to change oil. Shouild I trust this for the initial oil change? Do you have a suggestion based on engine hours as the van engine is used to run a pto source which is significant.

Engine oil change for break in period?

Leave it alone. More damage is done to engines by botched oil changes than any other cause. Don’t do anything early on the van, it has an oil filter. No problem? No repair.
