Mobil cautions about this though more at HM older vehicles. I think 20k is PLENTY of hours to coke up the pistons IMO.


So just that I'm clear, using Toyota conventional oil for the first 20k miles, then switching to Mobil 1 will be fine. Although, using Mobil 1 starting now would be even better. Thanks for all the help!

Mobil 1 just started making a synthetic media filter for this engine, but it's pricey. The only other synthetic media filter for this engine is made by TRD for around $12. Unless you're going over 5,000 miles on an oil change, it's probably not worth using anything other than the $4 OEM Denso filter.
