For those of you adding 2 stroke oil, how much are you adding per tankful? I am using Power Service curently in my 2002 Ford 7.3 and have not had any issues.
I run about 16 oz per tank (my 5.9 cummins & my folks' 7.3 powerstroke), usually only add ever other tank though.
From what I've read some people will run twice that much, but not many.
ps: Buy a small bottle of Walmarts Outboard (smokeless) and the gallon jug. Dump the small bottle and fill it from the gallon when you're ready for the next tank you'll have what you need.
