Because they were make in Korea I heard.

And that means anything, why??

What possible change would occur in an engine to make it run E85 that would change the weight of the oil? I can understand maybe injectors, maybe valve metals/ valve seats but I don't see how that would necessitate running a lighter weight oil. I think its just to improve fuel mileage for CAFE.

You are actually allowed to change your own oil. Magnuson-Moss Warranty Act (a U.S. federal law) prohibits warranty voidance solely because you perform your own maintenance, provided you follow the manufacturer’s specifications.

See above posts #13, #14, and the follow-up, #15.
I'm not allowed to change my own oil (unless I owned a licensed repair facility) if I want to keep it under warranty.

If your warranty explicitly states that oil changes must be performed by a licensed repair facility, it is possible for the manufacturer or dealership to deny a warranty claim related to engine issues if you perform your own oil changes, even if you do them correctly. This is because you're not following the warranty's stated requirements.

However, this restriction could conflict with the Magnuson-Moss Warranty Act, which prohibits manufacturers from voiding warranties or denying claims solely because maintenance was not performed by an authorized facility, unless they provide the maintenance free of charge or prove that improper maintenance caused the issue. This is true whether the warranty was free or not, cost is irrelevant.

Here’s the key distinction:

1. If the manufacturer proves negligence (e.g., wrong oil used, improper process), they can deny a related warranty claim.


2. If you comply with manufacturer specs (correct oil, proper procedure) and document your work, you have legal grounds to contest a denial under the Magnuson-Moss Warranty Act.

We have 5 other vehicles in our fleet. I have enough other maintenance to worry about. I'll just let the Stealership do the maintenance on the new Trax. We don't drive it much, so even if it needs 2 oil changes per year, the added cost of having someone else do them couldn't be much more than $100 per year. So, whatever. I pay a little more, and get to read the equivalent of a book or two while the maintenance gets done and documented. If we own the Trax for 15 years, that's ~$1500. Some people have to pay that just to buy an extended warranty, and not even a lifetime one, at that.

Hopefully, we'll never need the extended warranty, but since they gave it to us for free...
Like I mentioned before, It is what it is.
