I had some interest in this when the tax credit still existed and it was going to be super cheap. Still like the concept but not so sure of the value. Check a few option boxes on the SUV version and it’s right up there with a base Model 3. Nevermind that depreciated low mile Model 3s are in the 20s.
dexos began as an effort for GM to control the oil change market because the Quick Lube Industry was eating into dealer service department profits big time. So they attempted to get other oem’s to develop standards as well and that would make it hard for Quick Lubes to compete because all the oems would be different. GM faced lot of industry push-back, mostly the quick-lube industry and they went to licenses. Still GM it making a ton of money (est'd 30-40 million in 2025) off the license structure as they charge a hefty fee to get oil tested then require a royalty on ALL gallons sold applicable to GM vehicles.
Those are parts changers. It can get expensive though. I was a mechanic for 30 yrs. My truck has made this noise since new. I really don`t know what it is. It really doesn`t bother me. I`m still in warranty but have not brought it to the dealer.
I`m not buying the oil pump prime thing. Screw the TSB. I believe it`s in the trans pump gears. They rattle when that piss poor ULV oil drains off after a while. I believe those sharp tooth gears, with backlash, can rattle when dry. Not a vane style oil pump. Wonder who`s right? Me, or the TSB?🤔
Maybe I`m wrong?
