Take the Techron Trivia challenge here and you'll win a $5 Chevron gas card if you answer all the three questions correctly. I did this a few months ago and received my $5 card within a few weeks. Last time the cards went fast so hurry and get in on this fun promotion!
Offer is good in AL, AK, AZ, CA, DE, FL, GA, HI, ID, KY, LA, MD, MS, NV, NM, NC, OH, OR, SC, TN, TX, UT, and WA. You'll need to verify the email they send you after you complete the quiz in order to receive your card.
