I took home a sample of oil from the local Wendy's to titrate it before we run our 1st batch. Looked like good oil. Titrated @ 9.8 ml. twice. Thought what the heck? I went inside and titrated new virgin olive oil... .8 ml. Slightly used Soy oil - used once last Walleye fry - it titrated @ .9 ml. I think I need to get other samples from the Chinese places and Safeway (they use Canola) and forget about Wendy's.
