Hi everone, just curious as to what type of oil you folks who have the 223 I6 use. I'm going to be changing my oil for the first time since I bought my truck and I'm going with 10w-40. Also correct me if i'm wrong but does the 223 use 4qts instead of 5?

 

I use sae 30 non detergent but it is in a1954 that is what the book calls for.

 

I wouldn't use a none detergent oil in any engine . The 223 was a sludge maker, and using an oil which isn't HD would just add to the problem. I think i'd rather use 10-30
than 10-40. I had a 59 F100 with a 223 in it worked it hard for 15 years engine worked
fine. After a while the timing chain will talk to you, but thats no big deal to
replace, and you will have to adjust the valves if they get noisey, .019. I took care
of a few of them in the fleet I worked for, to bad the bodies didn't last.

 

Is this an F-100? Click the picture below for a scan of a lube chart. Let me know if you can't read it. I have a hi-res copy.



According to the chart you'll need 5 quarts of SAE 30 for temps above 32 degrees. Not sure which of today's multi-weight oils would be best. Kotzy's recommendation of 10W-30 would probably work. If you don't trust the chart, put four quarts in, run the engine for a few seconds and check the dipstick.

Hope this helps!

Thanks for the replies. The truck is a 1960 F100 but it has a 1963 223 I6 engine in it. I think i'll go with the 10w-30 and go with the 5qts per the chart that FFF posted.

thx.

 

My 223 has 10W30 with no problems but the oil amount is a bit inbetween, 5 liters brings it just over the full line.

 

I run 4 qts 10W40 Redline Oil and 1 qt Lucus oil.. Never had a problem and runs great on it in the Ca. heat

 

5 qts Valveline 10w-40 HD

 

The manual calls for straight 30 weight, so that's what I'm using. It's also cheaper...and I can use it in my lawnmower too.
