Anyone has a new Toyota that came with 25K miles complimentary toyota care program that includes oil changes and tire rotations? I took my 2010 Corolla in for this complimentary service and found that they use conventional 0W20 Toyota oil. I rather use synthetic, but they did not have this option under the free program. They also scratched my plastic engine cover and did not clean the bottom of the engine after changing the oil. I am now due for the second oil change and I wonder if I should continue with this program or spend extra money and change oil with Mobil 1 0W20 synthetic and OEM Toyota filter myself? I am sure they use the least experienced techs to do jobs like this...
