I just got an email from a guy from Lubrizol claiming I was among those picked off this website as a prize winner for filling out a maintenance surey. I did fill out an online survey a while ago here. He wants me to email my address to him so he can send me a gift certificate of $25. According to him several were picked as winners besides myself. I sure get a lot scam email nowadays - anybody else hear from this guy....is he on the level??? DV
