Hi everyone,
I have taken everyone's advice from this board and went out and bought some redline dfc for my new 79 300cd. I read the instructions and it said to use with 20 gallons of fuel. My question is should I pour it in when tank is full or empty? Should I wait until I do an extensive trip or is it ok to pour it in now and just ride it out in town and city? Some of you said use a whole bottle the first fill up and then use a certain amount of ounces after that. I want to make sure that I don't overdo it. I hope that I'm not sounding to rookish here. Just trying to be careful. Please help.
