RE: Synthetic
Welcome to the site.
You can get slightly better fuel mileage with a synthetic oil. It has good wear protection and some claim you can extend the drain interval, thereby justifying the extra cost. Synthetic has been around for many years and I think has proven itself to be a good oil.
You shouldn't have a problem making the switch to synthetic at that mileage. I have a 99 Carvan with around 145K and a Spirit with 172K and switched both to synthetic on the last change. The Caravan is using, leaking, burning a little more oil than usual. The Spirit lost about a pint in 1000 miles, which is about normal for it. Synthetic oil will leak past worn seals quicker than conventional oil, so that is why some people will recommend against using it on higher mileage vehicles.
Pick your brand you are comfortable with. I use Wal-Mart's Supertech oil. It is API certified. Many people recommend Mobil One. For the price difference and the fact that it does have the API symbol on the jug, I'm switching all my engines over to the Supertech. At under $13 for 5 quarts, it is comparable to conventional oil and about half the price of Mobil One.

RE: Synthetic
Mine has 202K, I use Mobil Clean 5000 and Lucas. I still change the oil every 3,000 miles anyhow. From everything I've heard, if you switch to a synthetic, or start using a product like Lucas, you have to stick with it. Anyone else heard that and know why? Or is it even true?

RE: Synthetic
No, you can switch back and forth without a problem. Oil just coats the surfaces of the engine to reduce friction. When you change it, the new oil just replaces what was there before. Some oils are definately better than others, but you can switch between brands, weights, and synthetic or dino oil without a problem. Check out the forum webbee linked to, it has a lot of good reading.
