I have a 2000 Land Cruiser. It doesn't travel as much as it used to but back when I was roaming Death Valley, AZ, UT, NM, CO, etc It literally never let me down. When I changed the oil (engine, differentials, gearbox) I sent samples off to Blackstone Labs. Every sample they told me to go up on the oil change interval (Mobil 1). The engine oil was changed on mileage, about every three months, sometimes sooner. I haven't driven it a few months and I guarantee you it'll start up like normal. I've driven Ford, Chevy, and GMC trucks all my life. I'll probably get a Taco when the GMC is done.
