What oil on fresh rebuild?

[captain j]

Just got my engine back from a full rebuild. I got it installed and am putting all the stuff back on. It's almost time to put some fresh oil in it and start it up. I think before I had it rebuilt I used 20-50. What do you recommend is good for it now. I know there will be a bunch if different opinions but let's hear them all. I did read on here to dump 4 in the pan and one through the dizzy hole. Good info and I will do!
Thanks josh

Mineral or some other cheap oil for ten hours, then remove it and replace with the 10- 30/40 of your choice.

After probably spending 2500$ (or a lot more), what did the rebuilder suggest??

yes ask your builder for warranty purposes

this is off the AER site read #1

i would change it after giving the engine its initial shake down. personally i do it 2-3 times after a fresh rebuild don't be penny wise //dollar foolish. you'll be surprised whats comes out and don't reuse it, oil is cheaper than engines

If you change the oil every 2000 mi or so with detergent type after a few changes the engine will be clean inside. Don't worry about dirt being embedded in the bearings, just change the detergent oil.

I us Rotella diesel oil cause It has zinc in it to protect
the lead bearings.

I suggest changing the oil after only 10 - 15 miles to be sure everything from the rebuild is out of the engine and again after 100 miles to be sure. Better safe then sorry and oil is cheap. If you wanted to you could filter it and use is again after the second oil change.

But of course what did the rebuilder tell you?

Oh my.

[captain j]

I'll give the builder a call today and see what he thinks I should use.

I always suggest the use of any good diesel oil in my rebuilds. I prefer Rotella but Delo or Travelers will do. I have also used Wal-mart brand if it is diesel rated.

Is there an additive in diesel oil that not in regular oil ?

[captain j]

Builder said to use whatever weight I prefer as long as it's a non detergent oil. He said that it's not good for the Babbitt it could seperate it from the block or cause it to flake. Ill prob go with a 10-40 weight non detergent.

Now I read in other posts that a lot you you guys use detergent oils????

What century is your rebuilder living in?
Clearly detergent oil doesn't harm babbitt or every one of our engines would be in the do over position and we'd be out of business for recommending it at break in and throughout the life cycle of the engines.

Bad information from the rebuilder. That's a warning sign that the babbitt will separate from the block and flake.??

[tbirdtbird]

J&M is right on. Also, you will be hard pressed to find a multi weight oil in Non-D anyway

[captain j]

What harm would it be to use a non Detergent oil anyways? Napa carries it. I understand with all of you guys using detergent oils that I'm sure it's fine. I don't want to go against the builder and have issues

OMG

Tell him that someone you were speaking to called him an idiot for giving that advice and ask him the reason so you can tell that guy off.

I'm real interested in hearing his reason.

The true story is ALL types of all are used in the model a and none have been proven to be bad for babbitt.

[Mitch//pa]

who is the builder since i am local to you

[H. L. Chauvin]

Hi Captain J,

Individual Recommendations: Oil is a much discussed subject on Model A Forums.

Sometimes it appears that all of the past varying types of oil recommended by individuals appear to be linked somewhat to whether the individual prefers white wall or black wall tires.

As recommended above, if you have a "warranty" & use what oil the rebuilder recommended, at least both you & your rebuilder will not worrying about oil for a long time.

I hope this isn't a defensive warning from the builder due to the possiblity of his babbit seperating and flaking.

This doesn't leave me with a good feeling about the babbit job.
