Have you realized that some dealerships are requesting you make an appointment to service your vehicle for an oil change? And if you do not set one up, then you risk showing up to a crowded dealership and having to leave or wait for several hours. This doesn't have to be the case where you waste an entire day trying to get your vehicle serviced! Switch over to Amsoil and not worry about changing your oil for a year while you protect your engine from stress and extreme temperatures! MADE IN USA! This is the recommended oil for your Am General H2. In our personal experience, buying your own oil and taking it to a local mechanic is much easier and cheaper than going to the dealer. We noticed that some dealerships refuse to put in your own oil. Hmmm, we wonder why they would refuse!
