Well , just added a 2020 Toyota Corolla 1.8L (non DI) to the family fleet ... This will be the first vehicle that specifies 0W20 oil in the manual , so my questions are :
- I chose Valvoline 5W30 Advanced synthetic for my '17 Hyundai Sonata 2.4L DI engine (very good oil - less VII adders to reduce intake valve deposits) . Can I assume the 0W20 in the Valvoline Advanced line up is equally as good an oil ? Since I believe the Corolla 1.8L is not a DI engine - then I worry less about VII adders -> intake valve deposits .
- Pennzoil Platinum 0W20 (cSt 8.6) , M1 0W20 (cSt 8.8) , QSUD 0W20 (cSt 8.3) and Valvoline Advanced 0W20 (cSt 8.4) are the main synthetic oils I will consider for typical mixed driving OCI of 6 months / 5K miles. *Any of these oils found to be a favorite of the Corolla 1.8L engine ?
- Interesting that the OM states to use 0W20 and that "5W20 is acceptable only if 0W20 is not available - but switch back to 0W20 for the next oil change" . So , no range of oil weights allowed as does Hyundai 0W20 , 5W20 , 5W30 . Thoughts on this ?
