Hi there, Novice Writer. It looks like this may have been your first story you’ve entered on WdC. So let me welcome you.
These are my suggestions only, so please take them as just that.

I think it would read better if you had mentioned Joe’s brother was called Derek in the first sentence because later you mention Derek’s car and the reader has to guess that he’s talking about his brother.
These lines: Joe drove his old Plymouth down the farm road as he planned to see if some of the remaining men would try to keep the farm and oil Derek's up and running. So far all who tried were killed. were a bit confusing. Derek’s what? His car?
Maybe you could have explained the brothers owned a farm. Joe was visiting to see if his guys there were all ok and to do a bit of maintenance on his brother’s car.


Writing ‘The end,’ at the completion of a story is unnecessary.
