OK, Steve, thank you....I've located a dealer (Stewart & Stevenson) in Longview, TX....about 30 minutes from where I am....they have both the concentrate and premixed in ample quantities. Anyone out there know for sure how many gallons I'll need to put in if completely empty? I'm guessing 20 gallons, at least that's what someone told me one time. Any confirmation will help! Just want to be sure to purchase enough so I don't have to make two trips....
