<p class="MsoNormal">In all of my modern vehicles, I run exactly what the owner's manual calls for. There are certain cases (like for example back when I had the VW TDI) that using the wrong oil could be literally disastrous. One of our current fleet is
turbocharged, and there's another place where the vehicle manufacturer has done extensive testing and knows best.<o:p></o:p></p>

<p class="MsoNormal">My "modern" (early 1990s) diesel tractor gets Rotella 15W-40. I'm not against using any other major brand diesel-rated oil in 15W-40, but it's so easy to find Rotella that I can play the brand-loyalty game even though I don't really believe
it.<o:p></o:p></p>

<p class="MsoNormal">All the gas-powered equipment gets a suitable viscosity oil in SJ grade. That standard goes back to before they reduced the ZDDP content, pre-2004. Typically I can find this at the parts store in brands that claim to be "Motorcycle" oils.
Usually 10W-40 and 20W-50 exist. For stuff that needs to run in the dead of winter (It sometimes gets down to 0F where I live) like for example the snowblower and the generator, get 10W-40. Mowers get 20W-50. Those high-output aircooled engines (Kawasaki
17HP and 24HP V-twins) run quite hot and I'll get the protection of the 50 end of the spectrum.<o:p></o:p></p>

<p class="MsoNormal">Hi John<br>
This May I needed to change oil in my Oliver 770. Yes, it is diesel,<br>
so maybe my answer here is not rellivent to your question.<br>
Anyway, it was the first oil change since I have owned it. I wondered<br>
what I should put in it. The book said 20w20 but the local Bomgaars<br>
didn't have any, so I called our family friend who is a mechanic at<br>
night, and always seems to know a little bit about a lot of things. He<br>
suggested I use 15W40 in it, but he said "do not buy anything but<br>
Rotella brand oil." I forget why he said Rotella, but maybe try that<br>
brand and see if it makes any difference?<br>
They do have 10W30. The only two gas burners left are my John Deere A,<br>
and Dad's 550 Oliver. Everything else here is diesel.<br>
Let us all know how it goes.<br>
Take Care,<br>
Tyler Juranek<br>
