Re: engine noise, cold weather start up....
10W-30 Should be ok for winter, but you might do fine with 10W-40. For my '85 either oil is "recommended." Things changed in the 90s, and I'm not 100% certain what is recommended.
However, while I have a completely different engine than you, it is normal for pushrod engines to be a little on the noisy side on cold morning starts. My engine quiets right down after the engine warms up.
If your engine isn't of the old-fashioned pushrod design, it could be you need to adjust the rockers (provided they are of the adjustable type). But again, expect to have some noise on cold morning starts. A slightly thicker oil will help a bit, but you don't want to go overboard. Stick with what's recommended for your vehicle. I'm not familiar with the engines that were used from '92 onward...
