Curious Who Uses Walmart / Super Tech Oil?

Or it's all a scam.

I'm cheap but I don't skimp on oil. Maybe on my son's car. Not on mine.

And the small savings on my single cylinder air cooled stuff isn't worth the effort.

Basically, the type and quality of the base oils + the type/quality of the add-pack/viscosity modifiers, etc. Another thing to look for is additional car manufacturer ratings. These are typically more strict (BMW LL-X, MB 229.X, etc.). If a particular oil meets several of those as well, then it's probably a safe bet regardless of the brand. Though, some of those 3rd-party ratings are application specific (diesel engines, etc.), and there is a big push towards fuel economy these days. So, "higher" ratings don't necessarily mean "better", and it's good to know what's what.

Here is an interesting tool for a basic/crude comparison between the different rating standards.

Don’t get me wrong, guys, I do not believe in using inferior oil. My argument was that the no-name stuff is probably just as good in a lot of cases. And for any car I service that specifies manufacturer rating, I NEVER deviate from it. For my VW TDI, (which calls for a very specific VW spec oil), I use Liquimoly or similar European brand. Same w BMWs, Audis, etc.

I think we are in agreement for the most part.

I have always used name brand oil. Piece of mind is better than the pennies I save over cheaper alternatives.

These are "natural gas" Engine-Generator sets. And they are not the largest that CAT makes.

Each unit is 1.6MW ~ 2000 HP. G3520C. The G3600 series are 4MW.

We actually run them on low BTU landfill gas.
