I use a good quality 10-40 w oil, but 10-30 w is also recommended by the manuafacturer.

I replace the filter and put in 4 quarts and start the engine and run it for a few minutes. A few minutes after the engine is turned off, then I check the level and add to full. I think when you use the long oil filter the capacity of the engine and filter is 5 quarts for a 250 l6.
