hello everyone. i would just like to know if this is normal. i noticed the other day when i got fuel($1. 80/gal) the other day. it was night so i could see the haze from my stacks under the light. the haze had a blue tint to it. i looked at my pryo gauge and it was at about 275*. is this normal or am i burning oil. i looked at the dip stick and it was at the full mark. thanks richard
