I have a 2007 Corolla bought last fall. I usually wait for synthetic oil to
come on sale at the local Canadian Tire store, and then I buy at least a
couple of jugs at a time. When I get my oil changed at the Toyota dealer, I
bring in my own oil and ask for a credit. I know that you can get your oil
changed elsewhere a little cheaper, but my dealer is good at looking out for
other potential problems while they do the oil change.
BTW, I'm getting some Amsoil MP metal protection spray today to undercoat my
car myself. We'll see how that works out.

Yes. Excellent explanation.

You might be able to take an oil sample out and send it to be analyzed
to see if it is regular oil or synthetic. Other than that, how do you
really know what they did? You can't for sure.
I doubt that they have high school students doing the oil changes at
most Toyota dealerships. However, if they do, the high school kid might
be doing an excellent job.

You can buy your own oil bottles from Walmart, O'Reilly, Autozone, etc.,
and ask the oil change technician or service rep. to return the empty
bottles to you. Shucks, I even ask them to return my used
oil filter ;-)
Last time at the dealership, I even tipped the oil tech guy, but the
service rep. told me the techs never get tips [chuckle]

When you undercoat the vehicle, make sure the underbody is pristine and dry,
otherwise, the spray may trap dirt and moisture between the coating and
underbody, accelerating rust. Also avoid getting anything on linkages,
wiring, and exhaust.
