I know that synthetic is far superior to conventional
I fear for the Solara if you give it to your daughter when time comes. Even 15k oil changes go right past the feeble minds of some women. Oops, I forgot daddy!
I say that Castrol EDGE is a checkbook slasher/pocket picker. They lost respect from me after they went with the whole non-synthetic synthetic BS...even thought Castrol is highly recommended.
Either way, even 15k protection doesn't guarantee anything:
"We don’t think oil type plays much of a part in wear, but we bring this up to illustrate the point that buying expensive oil doesn’t necessarily mean you can run your oil longer."
