So, I tried posting this on the Facebook page, but it quickly got lost in the YOHB shuffle. So, I went to the dealership to get Trans/Diff oil and was given a white bottle of 75W-90. I only got three bottles to do the front and rear diff. Forgetting that front diff and trans are basically the same, I went back to the same dealership to get more oil. I was then given black bottles of 80w-90 and told THAT is the stuff for STi's (I have an 09 STi). I have been unable to get any confirmation as to which one is actually correct and find it interesting that two trips to the same dealership yielded two different results. Any confirmation on which one should be used is greatly appreciated so that I can get this oil changed. Thank you in advance.
