Yes-do not use your card at the pump anymore.    The funny thing is that credit cards can limit you to $75.00 at the pump but what you don't know is this.  I put $20.00 in my tank & the credit card was authorized for a $100.00 transaction.  It took over 1 week & discussion with the fraud department to get the $80.00 that I didn't use at the pump put back on my credit card.  
The gas station used my $80.00 for their benefit, for 1 week, until it was put back on my card.  When is the last legal time you could use $80.00 of credit or debit without being charged for it for a period of 1 week?  We are so used to plastic that paper money seems to be a thing of the past.  How many people have you seen lately carrying plastic gas cans because they ran out of gas & the last gas station has a hold on their $$ so they can't fuel up again?
My experience has me using cash at the pump now.
