"petrol blue" is the name of the color of this shirt and it's a perfect color for a 'mechanic' shirt. Even if you can barely change a tire, wearing this shirt will likely make your more attractive, more interesting and hopefully a better mechanic. If not, we're sorry!
Seriously though, it has a cool OutMotoring patch over the left chest pocket and exudes coolness in a MINI kind of way.
If you're feeling extra special you may want to pick up a OutMotoring Mechanic Jacket for those cool nights by the track- or running to Sonic to get some icecream.
