What is the end goal? You have a 10 year old Toyota that is barely driven now. How long do you plan to keep it? How many miles a year, about 5000 miles or this going to increase post covid19? Let's look at 2 extreme scenarios 1) you get the oil up to temperature each trip and change oil every 5000 miles. 2) you don't do anything special to heat up oil and you just drive and you change oil every 20,000 miles.
I'd guess you'd have to go 50,000 miles before you started to see any differences between the two scenarios.
My in-laws have a 96 Corolla that is only driven to dr visits and the grocery store and every morning to the newspaper stand a half mile from their house. It's hasn't been above 50 mph in 20 years. They say it runs fine. There are many older folks that just drive around town.
I'd be more concerned about the exhaust system rusting out.
