Schaeffer's 221, 238, or 274 grease?

[Loobed]

What is better for my trucks suspension and linkage: Schaeffer's 221, 238, or 274 grease? I like the idea or extra moly in the 221 and 238, but I don't know if I need an "extra tackifier" that is in 238. The 274 seems to be better at colder temps. I have been in temps that go below 0*F (-18*C), so the 274 looks better. I like the idea of having an Aluminum Complex, rather than in inferiority inferior complex.

I am currently using Valvoline DuraBlend Moly Grease. Specs below.

For your application, the grease you are using is just fine. As for as which one of those Sheaffer greases is best, I would ask Salesrep.

All of these Schaeffer greases will work great for your suspension. Schaeffer's #238 is the "hulk" of the Schaeffers grease line-up and if only using for suspension will work the best, though it is really splitting hairs between these three Schaeffers oil products.

I use 238 in everything from ball joints to 4" excavator pins,5th wheels on and on this grease just works!

but like rep said there all good.

I'm running #274 in my Dodge 2500 suspension and drivetrain...it has served me well.
