Scheduled maintenance, when?

[MAC]

Got a question on “scheduled maintenance.“ Oil change, lub, tire rotation, etc. When? 3000 miles? Every 3000 miles? I bought a dealer service contract for $900, 3 years/36K miles, zero deductible. They told me it is $150 each service, well then, 4 times a year, $900 3 yrs sounded good. According to the H2 manual, it basically depends on the oil life indicator shown on the dash, not by the miles. I have 2200 miles after 2 months, at 65% oil life, and oil looks very clean, does that mean my service is at least 2 months later at approx. 4500 to 5000 miles? seems a bit too long. What’s your suggestion?

You can tell I am not the kind who knows what’s under the hood or the floor, I opened the hood for the first time today. Alabama Bill asked what is the sticky stuff on the underbody, I took one look at the Hummer and decided I am NOT going down there to look. Thanks for the help.
