What are the pros and cons of running a full synthetic oil compared to conventional? And with synthetic do I need to run a zinc additive for a non roller can?
Thanks!

I've always ran torco 20/50 semi synthetic with a bunch o zinc.
Not everyone carries it so kinda tough to get but leaning towards lucas marine oil,it's extreme duty so it says on the side and has a bunch of zinc also.anf I can get at local auto parts stores.

Delo 400 15w40 or Shell Rotella 15w40.
Found everywhere. More zinc than most.
$6-7 PER quart for "racing oil", or $13 a gallon for heavy duty motor oil.
Delo is all I use on 2 boat motors, 3 diesels, xr600r, etc...
Definitely use 1060 napa gold or wix 11060 filters (Chevy #'s)

You didn't say if your cam is a flat-tappet or conventional hydraulic. You need additional zinc during break-in on non-roller cams, then I use Mobil1 15-50 synthetic.

Advantages of synthetics include less carbon deposits in cylinders and throughout the engine, less wear, and longer oil change intervals. Mobil1 advantage is its wide availability at stores lite Walmart and Autozone and reasonable price, $22.88 per 5 quart jug. Disadvantages of synthetics are the higher price and they leak more from engine seals and gasket gaps as the engines wear. The conventional Dino-oils clog up over-clearances so you have less "sweating" and drips of oil. Many good oils out there to choose from. My engines usually die from breakage rather than wear! I change it once or twice a season, whenever it looses its transparency and darkens up. My boat engine consumes oil from all the sustained hour+ runs at 4,500 rpms while bouncing in 1-3' waves. I add a quart every 5-10 hours or so of run time. My spark plugs never foul with Mobil1. I have a mild Chevy Vortec 350 with a carb. My set-up also has dual oil filters, and of course I use Mobil1 filters. I also use mobil1 red grease on my jet pump. Happy shopping.

Thanks!

I going out on a limb here, but I think he has a non roller CAM, not a non roller CAN... :screwy:
I would avoid a synthetic for that very reason.

A "non-roller cam" could have either hydraulic or mechanical lifters. Mechanical lifters take more of a beating and would benefit more from Zinc.

Thanks! This is really what I was looking for.
