Again, can somebody show me a bottle of Mobil 1 Extended Performance 10w40 that the OP is talking about?


I see your point. Me bad. They don't make one. I will settle for the 10w30. I still think the OW-40 Mobil Synthetic will do though.

An A3 rated oil would do that 10k without much issue.
The alternatives you mentioned should do as well - Mobil 1 extended, or the Mobil 1 0w40, etc.
UNLESS your engine is a 1mz-fe (3.0l) as someone asked. In that case, I would change the PCV valve and use a good synthetic with a plan and a place to change it after 5k on the road.

EP comes in 5w30 for sure.
I've never seen it in 0w40.

If around April I might even stick dino in it, like Pennzoil conventional, and change to full synthetic right before the trip. And that is no April Fool's joke.
