Rear 80W90 or 75W140; front the same or 75W90.

When replacing conventional fluids with synthetic, you should remove as much of the old fluid as possible.

Bullhocky Syn and dino are the same thing one is just engineered in a lab to not
have as many impurities!! It's 2008 if you were to look at the actual molecule they
are the same chain of parts. Mixing the two is what a semi syn is, Some syn depending
on the level are actually made from out of the ground oil and some are made from other sources. Now the syntectic additives that are included are better since they
don't breakdown as readily as the additive package that is put into dino oil!! But the
extended change interval is not something I adhere to and swap out my fluid when it
is called for(mileage) or I note some breakdown or water intrusion.

The recommendation to not mix them comes from the factory manual I have.
