Is this right?

50 wt becomes cement at sub freezing temps...

Delo 100 40 wt

The point was Mike the guy used 30 w because he could not find 40w and people clouded up and rained down on him that was my point.

I know if it was my engine and I needed a couple of gals of oil and 15/40 or 30w was all that was available the old DD would need to acquire a taste for 15/40 or 30 w because that is what it would get.

Take Sean his Neo always ran at 200 degrees or a little above he never used 50W as the book calls for, the book is a guide line but you do what you have to do IMO

Even though i had 40 wt with me, the shop wanted to use 30wt for the break-in of my engine for warranty purposes. Told me that once i got back to Yuma i could change it to 40 wt if i wanted to even though it would have less than 2000 miles on it.

All shops use 30w after a out of frame rebuild Ed and run it for 5000 miles and then pull a sample

It is very helpful for members of this board to mention when sales of this nature are on.
    I just called O'Reilley's and ordered my three cases.
    Thanks for sharing the news!

A little wear is an essential part of break-in.

I don't know about your shop ED but Williams,United and Stewart and Stevenson use a 30 W with a high ash content like 1.27 for the break in period after a out of frame so do I

So on the subject of ideal oil pressure, what should we be looking for? What is an acceptable idle oil pressure reading?

[Ed Hackenbruch]

Clifford, i am not going to change it yet....it only has 1625 miles on it now. Will pull an oil sample when i change it.     

Geom, the book for my 5A says with the engine hot, 11 lbs minimum idling.

[luvrbus]

The 6V92 anything above 7 lbs is safe the turbo takes some of the oil pressure always check the idle rpm before checking the oil pressure and worrying about it takes away the stress off by 50 rpms makes a world of difference
