I was speaking with my Toyota service manager. He told me that any mods I want to do are fine and won't break the warranty. He said 1st time incident he can cover. 2nd time he needs to justify. He also said it's absolutely worthless to do the oil testing on a engine with less than 30,000 miles...
Yeah, not gonna try it. Deleted the LED on the wheel. Don't want to mess with it. Installing JB4 is more important than some flashing lights on the wheel. I looked at a lot of those videos. Seems some work others don't.
