2017 Yaris USB and oil question

[bentjazz]

I also have a lifetime powertrain, and I go into the dealer for all of my scheduled maintenance. Costs around $29/oil change for me, which is worth it because I don't change my own oil and in addition to changing my oil they give my car a good once over to see if everything is hunky-dory. The dealer also told me that if I change my oil on time, no need for synthetic.

$50.00 engine air filter I don't think so. I get a few free ones and some tire rotations so I got some time to think about it. I am going to go through the book and call them on the prices for various things. I did all my own maintenance on the 08 and she did fine so it is not a big deal to me either way. My wife has an 08 jeep JK which came with a factory lifetime powertrain warranty to the original owner and they let me do my own maintenance. Dealer knows I do things by the book so he doesn't question anything. It has around 150,000 miles on it and is on its 3rd transmission (for free). They put a factory heavy duty cooler on it right before they put the last transmission in. I keep it because of the warranty The road we use to live on was very steep and pretty bad. It ate Jeep transmissions for lunch but the Yaris ran the road every week day at least and was still going strong when I had to leave her

If you change the oil on time (5,000 miles or 6 months, whichever comes first - and the time is just as important as the miles, since it corresponds closely to short trips with little to no heat to burn out water and fuel contamination) then yes - you don't need synthetic for pure lubrication. BUT synthetic is less volatile - fewer fumes - so it keeps your engine cleaner (this is so important to GM that they are now specifiying full synthetic - dexos2 - oil changes for all their cars, even the most mundane). Also, there is a cool video explaining how conventional oil thins out over its live (the Viscosity Improvers shear down and can't do their job as well anymore) vs. full synthetic maintaining a more consistent viscosity without the need for VI's.
