hbgti, thanks for the read on the fix, but I wouldn't trust that type of a repair to the tech's working at my Scion dealer. From what I've read on here and other forums not many people feel comfortable taking their Scions in for routine service, ie oil changes, they messed up 2 oil changes on my xB and I've haven't been back.
I will probably just use a 5/30 syn oil and see how that works for my next oil change.
By the time Scion gets around to doing something about this problem most of the 08/09 xB's will be well over 100k and won't fall into their recall fix.
Again, thanks for the information!
