Our lemon 2019 Highlander was finally swapped out a little before 1 year of ownership. We chose to pay the difference to upgrade to the Hybrid model so we now have a 2020 Highlander Hybrid AWD. 2.5l I4 takes 0w16. After all the engine issues in our 2019 we will be changing the oil every 5k miles which will be about every 3 months. Mobil 1 0W16 seems to be the cheapest and easiest to get since it’s in stock at the local Walmart. Anyone own a Camry with this engine that has tried different brands? I see Valvoline is the thinnest and Castrol seems to be the thickest. Valvoline and Castrol are API SP and Mobil 1 is SN+. We put 100 miles on it yesterday and averaged about 34MPG at 81MPH. It’s so much of an upgrade from the 2019. It has an app you can remote start your car see the fuel gauge and miles to empty. Turn on hazards and lock and unlock the car. You can even see where it’s parked on a map in the Toyota App. The 2019 felt more solid and truck like while this one the suspension is kinda squishy and it feels more like a Jeep Compass than a Midsize 3 row. It’s got better acceleration than you would expect from such a heavy I4.
