Which Oil For Break-in?
Finishing my 383 SBC and I need to pick an oil to run. I want to run synthetic but I need a break-in oil so I was looking at the Joe Gibbs line, any suggestions on which weight? I know there will be more info needed to make a suggestion so ask away. Also, which weight synthetic and how many hours should I run the break-in oil before switching?
Thanks

If you are running a comp cam they have oil just for break in. Follow the instructions with the cam I believe it's 1800 to 2200
Rpm for 20 minutes varying the rpm but double check me on that it should be in the cam installation instructions as for weight I have used
Straight 30 weight in the past for break in. After the initial break in run change the oil if it a street motor I would not use synthetic at the first change put a few hundred miles on it and change it again and use what you want as far as synthetic goes. I am not saying comp oil is better than joe Gibbs it just what I have used for break in before.

This is the oil we use, we have tested all the other name brands. This is by far the best break-in oil we have found.

Someplace back down the list of posts is a great piece of information by an independent testor . .
Go read it . . . anything put up here in this thread is either redundant or possibly just opinion. I had several of my own "opinions" before I read it . . Now I have a lot fewer!

This is a solid roller race application with a single carb on gasoline that will be run on a stand before heading to the dyno shop, how many hours should I put on it before changing to synthetic oil? What break-in procedure would you suggest?

Go to track. Make a few passes 3 or 10 no set number, whatever you feel comfortable with. Come home cut the filter apart and change to the oil of your choice. I have been running the Amsoil Dominator racing. I have had great results with it, but I am going to be changing to Lucas 10w-30 synthetic racing oil. I can get the Lucas for about the same money, they are huge supporters of my sport, after researching I believe it will work a little better with methanol and I have never liked the way the Amsoil turns brown from red even though it doesn't hurt a thing.
