If you will do a search on this forum, you will find several threads with more text than the US Constitution on the favorite oils used by site users. And, Mobil 1, Royal Purple, Castrol, and others are popular here.

I've been using Valvoline for almost 20 years no reason to change now. Been using the Syn Power stuff for almost 10 with no problems. The last truck was sold with 210K and burned no oil and got 20mpg on the highway doin 80mph not bad for a 4.3L in a brick shaped Blazer. Oh and I change the oil every 5K.
You know here's my 2c:
Moving to synthetic, if you use a true synthetic, you should have better luck. That's what I did last oil change although my particular choices were derived from existing stock rather than first preference. I used what they had, and luckily they had the good stuff.
However, when (if?) the Big Guns come out, they gravitate towards a 'cleaner' of the synthetics, such as Castrol, Redline, or Mobil, all of which are flying Mighty high in the ls1 community, because of the various oil analyis seen. Though neither have spotless results.
In the short term the transition is not as important; both consistant oil changes and proper material choices are equally as huge. Obviously synthetics will normally run longer without needing an oil change (from what I hear). However, as a consumer it's virtually impossible to predict the oil change interval beforehand (even with thicker synthetics), without comparitive oil anaylsis done on each car during 'normal' driving conditions.
The result is, the printout is comprised of a percentage of various metals and contaminents, and an overall 'condition' analysis of the blend. This is what counts, although it doesn't hurt to analyze specific components. Afterwhich, the change interval, as well as the viscostiy and/or brand of oil can be modified, for both synthetic or blends, which as I said before can be very different from goals to goals, car to car, and budget to budget.
