I had an oil change done for my Cummins 5.9. Everywhere online quotes 12 quarts for this engine.
I purchased three x 4 gallon jugs and gave them to the mechanics to use. They put 1 in the filter but another 13 in the engine. They went by the line on the dipstick, which they showed me.
So ....
1 - Why does 14 quarts fit and show ok on the dipstick, albeit at the full mark.
2 - What should I do, remove the extra quarts? Or leave it? What would be the issues if any?
