i have about 3k miles on my rebuilt motor and have not switched to synthetic yet..... although i did buy the castrol dino/syntec blend for this next oil change.... i may just go with the blended mixture and change the oil every 1k-2k or 6months whichever is longer

I currently run Amsoil 10w30 in everything I own (even my mower). After the 383 gets broken in it will go straight to Amsoil as will the tranny & all greases. I like Amsoil, but others are just as good. Synthetics rule!

Valvolene Racing 10W-30 for the first 1000 to 1500 miles, because of the higher zinc. Then will change to Castrol GTX 10W-30.
I change oil twice a year and put on about 1000 miles in a good year. With the alleged extended drain intervals (milage) with synthetics, I would be changing oil every 5-6-7 years. Don't like that.

Comparative Motor Oil Test
When running a mult-viscosity oil, keep in mind that an oil requires viscosity improvers, or VIs, to increase the spread. As these VIs breakdown, the oil will go out of grade, particularly the cold grade. Mineral oils require more VIs than synthetics do. A good 10w30 synthetic, e.g. not a group III synthetic, requires very little VI to meet the 10w standard. So, if you go with a multi-vs mineral oil, I would stick with short oil change intervals.
