Can I pour a 100% Sea Foam Motor Treatment into my diesel engine fuel filter? If so, is there a sequence I need to follow after I have started the engine? I have a 2004 Chevy 2500 HD 6.6 liter diesel.

Good question.
Yes, you can. Here’s a summary of the instructions:
Getting started: Add a cleaning dosage of Sea Foam Motor Treatment to the fuel tank. Best to
add at least 2 ounces per gallon of fuel when tank is low to maximize treatment concentration. I like to add a full can (16 oz) to a low tank of fuel (1/8-1/4 of a tank).
Hope that helps!
So my friend has a 6.9 1987 Ford F-250 we did this per instructions and his engine sounds more crisp , more in tune and just overall idle smoother , before it would miss like a loping idle and shake and just sounded wrong and now what a difference, It works
