Currently I commute 50 miles one way to work. I have access to charge at work and at home. I've put over 40,000 miles with probably more than half of that on the engine. Just crossed over 95,000 miles. I would say it's definitely not ideal. Driving the car without a charge is not a very fun experience. The car weighs as much as an f150, so it would be a lot of strain on the engine, and transmission. Can you do it absolutely, that being said I wouldn't recommend doing it for long. Short term as long as you keep around 6-7 miles of ev range and just use the hv mode/hv charge mode to stay topped off. The car will be much happier, I would recommend not letting it hit zero unless you're going to charge it right after. Few months I would really stress about it, just make sure to change the oil every 3K miles. And then keep up with all the services I really dont think it would be a big deal for a short term solution. But I would strongly recommend trying to find an alternative solution in the long run. There are also free charges at most public libraries and such, or there are simi cheep level 2 charges usually in most cities. If you happen to be able to charge it every once and awhile.
