Im looking to do first oil change on Sienna. It is recommended 0w20 or 5w20 and total needs 5.8 qts.
I picked up Castrol Magnatec 0w20 5 qts, and i still do have new 5 qts Mobil 5000 5w30 in garage.
Should i mix them or should i pick up another 0w20 5qts?
Im pretty sure 99% will say use them haha
I strictly use in my SIenna 5W30.
Those engines can run pretty much anything, and your manual does not say that you MUST stick to 0W20.
Same engines in Europe are recommended for 5W30 ACEA C3, which are borderline 5W40 oils.
