My only purpose for switching to different viscosity is for engine longevity. I don't care about gas mileage.
I want this bad boy to be my last vehicle.
I don't have any data. I only read what's on the interwebs.
Chat gpt mentioned the new engines have tighter tolerances than previous gen...
I searched chat gpt and it said the 5W-30 is more for the older engine. Juat like the guy in the video in a previous reply said.
If you can point me at a research that proves the 5W-30 is better on the 6G 4Runner, please do.
I am going to change my oil at 1000 miles this weekend. I live in Az and we now get 3 digits heat. Does anyone use a different viscosity? The manual we can use 5W-20, anybody else did some research and use other viscosity?
Good morning guys. I have this same issue on my 6th gen 4Runner TRD OR. It is dripping in my garage. It's not water, it seems to be thin oil. I will post pics and a video later.
Did the op have the dealership what cause it?
