don't believe there will be warranty, or oil related issue with the warranty. There are two warranties on the truck. The standard warranty provided by Toyota and a complimentary Lifetime Powertrain Warranty. How I see it is the UOA will provide a baseline reading should something happen. Just because you don't change a fluid or do a recommended service does not mean that you void the warranty provided.
I bet both warranty state OEM OCI's.
Why wait 20k to start UOA's? If you're that concerned with doing 10k OCI's then start UOA's at the first oil change to show a trend..
Remember, you have to prove in a Court of Law that you were in the right regarding Oil Changes. How long will it take and cost you in lawyer fees, while your Tacoma is sitting broke somewhere????

I will use it for tire rotation and to lube, no oil.
What lube? Most modern vehicles have sealed bearings, ball joints, tie rod ends, etc?
You get free maintenance and won't use it? What a waste of time and money!
