The Ford Barn

Before I get beat up, I tried to find the answers through a search but couldn't find any. (I don't have good luck with the site's search function) So I thought I'd just ask them.
1. What quantity of engine oil do you use when changing it? I thought I read somewhere that most people use less then what is called for in the manual.
2. Do you guys use any type of sealer on the transmission drain plug? Mine developed a small drip and I want it gone. Plumbers dope? Silicon? Teflon tape?
Thanks.

I know, that search function can be frustrating. These are pretty common questions. I put four quarts in when I change it. Some put 4-1/2, but in my personal experience I've found that to be too much.

Regarding the plug, a good washer should stop the leak. I have a brass on one car and a kind of plastic somethingorother on the other. The plastic one came with the car, and it works, so... if it ain't broke, I don't try to fix it. I don't put anything on the threads.

On the transmission use teflon tape or #2 permatex.

4 quarts regular oil/filter change, 5 if the pan has been off.

I use 20w 50w wal-mart brand, about 1 quart will stay in motor at oil change..

Oil dripping from the drain plug could be coming from another source and finding the lowest point to drip from.

OK, it's going to be Teflon tape and 4 quarts of 20w 50w oil. (I'll get 5 but use 4 if that's what it wants.)
newshirt, I checked the area around the plug by wiping it clean/dry then running the engine for a while, let it sit then checked the area again and found the surrounding area to be dry but the bottom surface of the plug with a small amount of oil ready to drip. So, off to the store to get some fresh oil for the engine and I'll reuse the trans oil as I just replaced it approx 10 miles ago. Thanks for your input.

Try tightening the plug before you drain tranny.

I use 10-40 here in the area of Oregon we live in. I would guess the weight of the oil should be considered based on the area you live in and the temperature considerations for the time of year you drive it. I agree that the drain plug on the tranny would have a hard time to leak unless the threads are really messed up. Would check for another area for the leak.

The oil is changed and a new brass washer fitted on the plug. No leak.
I tightened the trans drain plug as much as I could, within reason. It did move a little bit, hopefully enough to seal it. If not I'll remove the plug and wrap it with teflon tape and call it done. I looked all around the the trans for another area that would cause the leak and found nothing. There was the usual oil moisture but nothing that resembled a source of a leak. So, I'll check it tomorrow and see if the little bit I was able to tighten the plug was enough to seal it.
Thanks for all your input (on such a basic subject!)
