I wonder if this is a good Petrolhead quote? I made this one up myself.
"I don't care about miles per gallon, I only care about smiles per gallon."

That has been said a lot

Yeeah, not that good but keep thinking and dont give up, someday your quotes will be in history books.

I got one.
Don’t drive towards someone who you do not intend to kill.

Well it’s not exactly original but I agree with it

I don’t get it, if you’re smiling the whole trip and use 3 gallons, then isn’t it technically 0.33 smiles per gallon? lol, it is a good quote though

Here’s mine. The only type of clouds that Petrolheads like is the one that comes from a car’s tyres.

Sure you made it up. Did you travel back in time 5 years ago when i heard it first and said it then.
