High Viscosity Oil in 2.0 RAV4

[MrQuackers]

I bit on that Walmart clearance. Decided to use it (Pennzoil High Mileage 10w-40) in the RAV4. So far I like it, very smooth scooting down the highway. This vehicle is truly HM at near 300k miles. Not tracking mpg yet. Maybe it will improve efficiency. Stranger things have happened

Glad you like it.
At operating temperatures, no commercial oils is too thick.
