I wanted to get another type of credit card of some sort to show that I have open lines of credit. Right now I only have 1 Visa credit card. I was thinking about getting a gas card to use in case of emergencies, maybe from like Chevron. Are gas cards good for your credit to show another open line of credit? I mean as long as I pay it on time and keep it to a low usage percentage right? Or would a regular old Visa/Mastercard be better? Does it matter? Whatever is better on my credit is what I am looking for, any input would help. Thanks
