Hey guys. I bought 2 80oz bottles of PS Diesel Kleen (Grey Bottle). I was wondering would it be ok to put it into my big 500 Gallon tank. Would it break any of my engine components of my trucks and tractors? Hope to hear from your guys' input. 
Are you trying to treat your fuel against gelling? IIRC, the grey bottle is just a cetane booster, the white bottle is anti gel and cetane booster ( I use it year round anyway) and the red bottle is "holy ****, I'm already gelled up"
As for hurting anything, um no, after all the product is made to be a diesel additive.
Yup, 160 ounces (minimum) for 500 gallons. But you should be using the white container this time of year. The silver container is intended for use when there's no threat of gelling.
