What happens if I make more than one payment per month on my car from Ford?

I want to ferociously pay my car loan off as soon as possible. My car payment from Ford is due every 15 of every month, but I was wondering if I could make more than one payment per month. Lets say if I make 6 payments in one month of 100 dollars on top of the monthly payment due on the 15 of every month, is that allowed by ford, or do they charge a fee for making extra payments on their car loans?

Thoughts on Doug Ford and who will be tougher. Doug or Trump?

While I don't agree with many of his policies mainly because hes conservative and I'm skeptical of where his cuts are going to be.

I'm glad to see hes working with Trudeau and hes going to fight these ridiculous Tariffs Trump is putting on this country.

Time to give these Yankee's a hard pull.
