I used BG in 2 of my Eclipses (which have the worst shifting transmissions) and BG was like night and day difference, I switched to GM Syncromesh on one of the cars and it worked better than the factory fluid, but BG still worked better.

Just My Experience, try and see which you like, you can always drain it and try something else.

 

I don't trust the royal purple because my friend did a commercial for them, and it was all bogus. He had a racing school and in the commercial he was raving over how good the royal purple was. When I asked him if they use it (it's free) he said "uh no, we're not too sure of it"

 

Royal Purple is junk, sorry to all the lovers of it out there. The company was started by a salesman....the products are just that too, all hype.

 

crap. just when i was going to post to not waste your money on royal purple. for what they charge, that oil is crap. you can get much better oil for the same money.
