200K Transition Mobil1 To Amsoil
- Thread starter RobbS

But not for much longer intervals with perfectly good engine oil ready for more miles to go. Mobil1 can't and Amsoil can
I’m not sure you’ll see any benefit going from EP to Amsoil. Especially going 5K on EP to 10K on Amsoil.
The Amsoil is a good product, but it’s not magic, and it won’t do anything drasticly different than M1. Sure, it has more additives (TBN), but depending on the EP grade the base oil is probably only marginally “better”. In a low performance Corolla that difference is largely irrelevant imo.
The EP is capable of 10K or more miles as well, that doesn’t mean you should do extended intervals however.
I would as suggested above, run your Amsoil at 10k intervals and call that good.
