39.9 cents per gallon for Chevron Supreme, 36.9 for Chevron. From what I could find, the Chevron logo used here started in the mid-80's. If that's correct, the price per gallon would be very low, thus the prices might be from that brief period in the 80's where some older pumps, because they could not display prices over $1.00, were converted to price based on the quarter gallon
