I have a 2014 Lexus Es 350 where the recommended fill is 0w-20. Non-Lexus dealer where I bought the car filled with 5w-30 synthetic.
My understanding is the 0w20 stuff is for fuel economy and the previous generation of ES had the same engine but the manual recommended 5w-30. I live in a really hot climate (Arizona)
I could care less about any MPG gains. I just want the best oil protection.
My first question is:
1) Can I leave the 5w30 in there?
2) Which is the best oil for motor life 0w-20 or 5w30.
I don't want to put in a "too thin" oil to hit some arbitrary CAFE number at the expense of engine life.
Thanks again
