I found that my 65 has a oil drain plug different then any I have seen, but this is my first car older then 69.
The drain plug looks like a torx style, maybe a t-70? but I was able to use a ratchet that fit in the hole along with a small pipe wrench on the outer edge. (Way Way to tight,and the filter was too!!)
So , is this the correct plug for this car?

 

yep.

 

Thanks, Is this a torx? I do have a t-70 that was a little to loose,but could have worked if it was not so f ing tight.
Why would someone tighten this so much, and the filter too! I just don't get it!

 

Use a 1/2" drive ratchet ONLY without an extension. It should work fine. An extension usually slips in the splines and rounds them out.

There's a special 8-point tool especially designed for this drain plug but it's not commonly available anymore. Olds used this plug 1959-67, so it's not totally off the wall.

 

I saw a special antique GM tool on EBAY a couple of months ago that was for removing the drain plug, I thought about buying it just because it was so oddball. 1/2 ratchet works perfect.

 

I would like to see that.

 

Another Olds guy pointed out to me that in a 1965 A-body (probably '64 too) if you use the more common oil pan drain plug the bolt head will hang just below the front crossmember... so if you scrape going over a speed bump or anything else it's the drain plug that will be scraping

I have seen that happen, but it was on a 1970 SS with a after market nine quart pan. After a hard launch it came down and turned the plug out of the pan.
