Subject: Re: [T3] Engine oil temp?<br>
<br>
Yes he did , and I understand how this works. And this has to do with oil<br>
weight and of course bearing clearance. I use SAE 40 even when I rebuilt<br>
this engine and on a hot freeway run I'd come to a stop and the oil light<br>
would come on. This is why I didn't go down to SAE 30 , 30 may be fine<br>
