I hope your employment situation changes for the better SOON.
There are lots of folks in your situation.
Your oil and filter choice sounds very good, both have a good reputation.
Particularly in cold weather, having a occassional trip that is long enough to get your motor warmed up to the point that moisture will be able to evaporate out of the system would be a good idea.
Even 20-30 minutes should be plenty long enough to do a pretty good job of that....particularly in FL where it does not get as cold as many other places do.
Hopefully you will have a GOOD job by the time cold weather comes back around.
The other thing to keep an eye on is your gasoline.
Sitting in the tank for as long as it is at 20-30 miles a week could cause some issues.
A fuel system add, like Redline Fuel System Cleaner (in a maintenance dose) would be my choice.
1 bottle will treat at least 3 tanks of gasoline in a maintenance dose.
There are other quality fuel add choices as well.....
