Or switch back to Mobil that I first used a few years ago?
I should also mention that she generally warms up the truck only for 10 seconds in the morning...although I tell her to warm it up at least 30-60 seconds.
Also, she does not speed to work.

I'd change it twice a year and what happens...happens. Heck it's only racking up 4 miles per day, it could last a long time. And for that trip it doesn't have to be in optimum condition. If it does wear out, there are used SBC engines which could buy her years more service at that rate. No need to bother with annoying warm up procedures.
