Oil change before injector swap

[95Strokeee]

Hey everyone, I know I've been making a lot of topics recently! But I am changing my injectors to stage ones, as most of you may know. I also need an oil change, should I change my oil before installing the injectors or should I change it after? Does it matter? Thank you

Shouldn't matter unless u have real high mileage oil. I'd put new oil in before firing up new injectors, nice n fresh oil for new injectors.

After. After the fuel and oil from the rails drain into the cylinders, it can make it's way into the crankcase (depending on the method you use to get rid of the drained fuel/oil). Changing it after would at least get rid of any fuel that may have gotten in the CC. Cheers!
