I have one vehicle that needs 5W-20 and another vehicle that needs 5W-30. I'd sure like to just stock one weight of oil. I'm considering just putting 5W-30 in both vehicles.
Your '07 FJ Cruiser has been back spec'd for a 5W-20 grade.
And since you're not adverse to using expensive oils I'd recommend Amsoil OE 0W-20 for both. It is heavier than an OEM 5W-20 but not as heavy as their OE 5W-20.

I've heard that elsewhere but I've never been able to find a reputable source online. Can you tell me where you heard that?
It's the recommendation of Toyota Canada but the source of the info actually comes Toyota Japan.
Amsoil 0W-30 is no lighter on start-up than a typical premium 5W-30 syn.
My recommendation of Amsoil OE 0W-20 for both the Caravan and FJ is conservative as that oil has a higher HTHSV than what the OEMs require.
Either or will work just fine. If you like 20 grades go with them,or if you prefer a 30 grade then stay with it.
The 20 grades will gain you a minute gain in fuel economy if you care.
