You don't necessarily want the cheapest oil, diesels need GOOD oil. I am a diesel mechanic and I highly recommend Shell 15W40 motor oil.

I would say the average grade of oil used in a Duramax is 15W40
Yes, synthetic motor oil can be used in a 2003 GM Duramax diesel engine. It often provides better protection and performance compared to conventional oil, especially in extreme temperatures. However, it's important to choose an oil that meets the specifications outlined in the owner's manual, such as the appropriate viscosity and API ratings. Always check for compatibility with your specific engine requirements.
15w40
The drain plug for the engine oil on a duramax should be on the back of the oil pan at the very bottom.
I use Amsoil 15W40 fully synthetic oil in my Duramax 6.6 LBZ. Runs great and no problems.

It can causes serious damage
I have a C4500 with a 6.6 Duramax and it takes 16qts. with the filter, also change your fuel filter with every oil change.
