Just wondering if 1 year old le-607 diff fluid is alright to use. Thoughts, opinions?

 

If the bottle was sealed I don't see why not.

 

Its not a good idea to drink it but if you mix it with a soft drink or dilute 1:1 it will be fine... Mikey said so....

 

If it's in a sealed bottle it's 100% OK to use.

 

If it were in your car for a year it would still be okay also.

 

It turns the bottle purple after a few months... lol

 

Cool. but after mixing it 1:1 with a soft drink I dont feel so well.

 

Not necessarily. Oil oxidizes over time. hence the reason your owner's manual gives both MILEAGE and TIME as intervals to do OCIs. Whichever comes first, you should change it.

Also, keep in mind, LE607 is NOT synthetic. So it will oxidize faster than say Mobil 1.


I would never leave LE607 in a diff for more than a year.

 

Does anybody know OEM diff fluid is synthetic or dino ?

 

WI,

People have had this stuff lab tested at the two year mark and it was still going strong. Why the one year limit?
