Would using B100 cause the car to exhibit blue smoke more?

I've read the posts here and this is funny because blue smoke is what happens to vegetable oil when you pour some into a hot frying pan! Try it sometime! Although you will have some wear in your engine at 366,000 miles, I recently had my head totally overhauled and a 3 angle valve job performed and I still get blue smoke when first starting out. Cold starting in the '30's is not a problem and it fires right up the first time. I took mine to Emissions just for curiosity and it passed with flying colors! Blue smoke from a veggie burner, which is what biodiesel is, does not cause concern at federal emissions testing stations. According to them, if it did, they would have to shut down every fast food joint belching blue smoke from their billowing smoke stack grill vents during lunch hour!!!! Veggie smoke is considered biodegradable and not a health threat. Except for what is cooking on the grill that could wind up on your waistline!!!!
