We have a 2010 Sienna, 2GRFE engine I believe, with almost 10K miles on it now. I have 20K miles of free oil changes with Toyota conventional, but I'm unsure about what oil to use when I'm on my own. I don't want this to turn into a brand war that can't be backed up with facts, figures, or evidence, so please only let me know if you've had experience with certain oils in this engine. I currently use M1 5W-20 in my Civic with wonderful results (from what the eye can see, body can feel, and ears can hear), but was unsure if the 5W-30 would be optimal in the Sienna or of there was something that ran smoother and kept this engine cleaner. Since the engine's been around a while, there has to be lots of data available for it. Thanks for the info!
BTW, our trips are at least 30 minutes long one-way and 99% of the time it is brought to normal operating temp. That's not much of a factor since I'll more than likely want to use a full syn. We live in south Louisiana so summer's get around 100 with high humidity and winter's get around 30. We drive the vehicle easy with occasional revving with good intentions.
