Dumb questions that deserve good answers.

So for changing my oil in my massey gc1715 . . . Instead of using my Havoline favorite . . there a real reason to use a "diesel motor oil" ??

I'm not saying I dont believe it . . But its a little hard to swallow as many years as I've been around oils.

I'll do some checking on it. At least Castrol is my second favorite brand aftet Havoline. Lol

Oh balderdash ! Relax. Your user's manual tells you what "services" the oil should cover that you use. API Service Classification CC or CD for example. Just confirm that whatever oil you buy includes that "service" in the fine print on the jug. Whether it says diesel or not doesn't matter so long as it lists the "service" your manual specifies. If it says "diesel" on it OK. You will never know the difference in this lifetime. Favorite brands are also fine (if you care) but that will never matter either in reality. All of the east vs west wax content and so forth mentioned above is obscure, negligible, and mostly old wives tales. Just get on with it and don't sweat the small stuff (in my opinion of course...)

It is my understanding that compression-ignition (diesel) oils were needed because of the naturally higher build up of soot in the oil, and that diesel oils have additives that will hold that soot in suspension rather than building up in places where it could lead to problems.

Years ago, it was explained to me that this is the reason most diesel oils will turn very black very quickly after changing, and that the very dark color of the oil is not necessarily an indication of "old" oil as it often is in spark-ignition (gasoline) engines. Curiously, the oil in my GC stays relatively clean for quite a few hours before turning black. :confused3:

I'm sure there are other differences as well, especially if there's a turbocharger involved (not on my GC, for sure! :laughing.

I do know that in two of my vehicles --with turbos, both German design-- the manufacturers were VERY specific about only using oils that meet their quite stringent specs, and only synthetic at that.

JWR is correct, however: both service classifications he mentions begin with a "C," meaning compression ignition. I use Rotella in my tractor, but choose to use their T5 synthetic blend, CG-4/SM.

"Balderdash" ?? Last time I heard that word was more than 40 years ago. And then it was a rerun of an old 1950s "Tennessee Tuxedo" cartoon show. lol.

Is there a link or location available that allows calculations of fluid needed to fill/load tractor tires (lawnmower sizes and scut sizes) ??

. . But I know in the 70s as an example that texas oils and pennsylvania oils were diffrent because oil pans would have a waxy build up on the bottom of the oil pans if Pennzoil was used compared to a texas brand. It used to be one of the reasons that Pennzoil or Quaker State were priced lower than the Texas based oils.

Much has changed in forty years and that includes lubrication technology. The Pennzoil full synthetic that I use in my car isn't even made from oil- it's made from natural gas. As a previous post suggests, I'd be far less concerned about brand and far more concerned as to whether it meets the requirements spelled out in your owner's manual. As good as the oil that I use in my car is, it will never see the inside of a diesel- afaik it doesn't meet API certifications for diesel use. Shell (who owns Pennzoil) does make oils specifically designed for diesel use- Rotella. Using an oil that doesn't meet the requirements spelled out in your owner's manual, no matter what brand, is just asking for trouble.

Here's one chart. Not sure if your tire sizes are on this.

It's a pdf file. You need Adobe Acrobat Reader to open it. It shows its there in my post and it opens for me.

I don't even see a link to it. Can you pm me?

Check post 10 in this link. Your tires may be there. Or do a google search for tire fill chart. There have been many posts on the subject.
