Before this gets into a huge technobabble about high compression and detonation, you should use whatever the manufacturer states. Period. Don't take advice from a salesman that is telling you what he thinks you want to hear..

If, if you don't have spirit driving during this 900 miles and do follow the break-in instruction by your owner manual, your car would be fine as long as you immediately switch back to what the owner manual suggests, 91 or better.
87 should be fine for normal/conservative/mild driving. I believe there are many ppl outsides this forum using 87 or 89... However, 91 above is the best for your 04TL. IMO. If I see Grandma feeding 87 into her 04TL, I won't stop her and waste my time to convince her how necessary the premium gasoline is... :o
