texas Ashland oil. via Valvoline. ( my my guess is special new EP , additives used allow that)

Does walmart ship that valvoline 80w-90 gear oil GL4/5 worldwide??

Can the Valvoline-High-Performance-80W-90-Gear-Oil-1-Quart GL4/5 be used in both transfer case and front/ rear differentials??

i can speak any company or shipper, only you can easy, click add to cart then answer the questions bingo your answer.

question #2 yes.  that is why it has both GL4 and 5 on the label , and means just that, yes.
