·I see the new statement from Toyota Customer Service about using synthetic
oil still states if you switch to synthetic oil, you should not switch back.
I have tried repeatedly to get Toyota to say why this is recommended in
their vehicles. I want to use Mobil 1 in my 2004 Sienna because I change my
own oil most of the time. However, for those times I need an oil change and
have to go to the dealer, they will most likely only use their conventional
oil. I sure would like to know what the problem would be if I did this.
Mobil 1 has long said their oil is compatible with all other conventional
oils, and you can use both from time to time. Charles Ranheim
