Is there a preferred lubricant for leaf springs? TIA

Just an understanding of why it’s that way…

So has it been discussed for 20 years, or has nobody else noticed? Interesting responses in this thread.

Do you not notice a difference with M1?

OK sorry I wasn’t clear. I’m not concerned about the store shelves, but the separation. Why is it uniquely bad about separating?

Being possibly the #1 lubricant manufacturer in the world, why is M1 the only grease that reliably leaks on the shelves in stores? Couldn’t they do better? Am I wrong for assuming this is an issue?

Is the primary reason for choosing C-series oils over A/B oils the compatibility with DPF/GPF?

I already used traveller 15w-40 from tractor supply when I had a PS 6.7. Anything meeting Ford F1 spec is fine.

And most of these emissions devices reduce fuel economy, in turn increasing CO2.

and there are plenty of mixing calculators online. The short answer is that if you blend a two oils 50/50, you'll get something slightly LESS than the average of the two. You can verify this yourself on the calculators. Of course, these are just estimates.

Wow how ignorant

I use Traveller 15W-40. It’s like $10/gallon and meets all the specs.

I doubt it because their position statement on CK-4 came out very early. Early presentations shows some internal tests with proposed new CK-4 formulations.

I don't think the government is directly specifying anything here. The issue is DPF longevity.
