Mixing synthetic oil and dino

[JPhil]

Will it hurt anything to drive my car for a couple hundred miles with a mix of dinosaur oil and synthetic in the crankcase?
I recently had an incident where I lost most of the oil (no damage, I caught it in time) but had to put dinosaur oil in it to get safely back home. For reasons I won't go into, I haven't been able to take care of it yet. Last night I found out about a funeral today that I need to go to and it is important to me that I drive the car.

as long as it's the correct viscosity it'll be fine but I wouldn't want to leave it in there for another 3000 miles ...

10-40 Amsoil synthetic and 15-40 Rotella CI, about half & half each.

Rotella is a Diesel oil but I doubt it will hurt anything....

Don't they sell part dino, part synthetic oils? Must be OK to mix them.

Simple fix, just drain out the half 15w-40 you put in there and put in the correct 10w-40. Oh, wait, this isn't CFOT. Wrong place for a smart ass comment!

See. If you ask, someone has the simple answer.:search:

What if I just add some straight 5w to bring the 10w-40 up to 15w-40?

Your just going to be carefull in how much you add.....you see, with a 50/50 mixture, you currently are running 12.5w-40.
