The towing package is optional, maybe an extra $39 a year or something, but offered through the insurance broker that I went through. I went through a broker, because they could compare the rates from many different insurance companies, and get me hooked up with the company that offered the lowest rates.
That particular broker appears to have gone out of business last year, and I got a notice that I now have a new broker. I don’t know about them yet, but the old one would check every year when it was time to renew my policy, and if a different company was better deal, they’d notify me and ask me if I wanted to switch.
I believe there are different kinds of gas treatment, that offer different benefits. I get one that specifically says carburetor or fuel system cleaner. No particular brand, just one that says it’ll do what I want it to do. They seem to work well for carburetor’s, but the one I tried for fuel injectors never helped, and I wound up buying all new fuel injectors. That’s just one of the reasons I prefer carburetors.
