Differential and transfer case oil

I was looking at the Walmart Supertech as they can be had for cheap. Anyone else using 85W-140 like ECGS recommends?

 

Couldn't agree with you more.

 

I have always thought the same about AMSOIL, though I have no experience with their products I have heard great things.

It's worth noting that the study was conducted by AMSOIL. Aside from Project Farm on YT it seems like there are no independent tests comparing AMSOIL to others.

 

Amsoil

 

oh no, not another oil brand thread.

 

Right.....

But its worth noting almost everything is better than Lucas branded products (including engine oil).

 

That's a good video, I usually reference that when people bash Pennzoil for it's bad reputation decades ago. They've come a long way since then.

People buy into oil brands like they do religions though, hard to sway someone's opinion when they're sold on one vs another

 

People just didn't like the parafin wax they had in the non-synthetic oil. I find it similar to people who bash fram for making bad filters.

 

AMSOIL seems to be one of the few lubricant company that releases test data on there products. I appreciate stuff like that.

 

Shoot for $15 for 5 quarts of Pennzoil at most of the parts houses it's hard to beat.

 

Damn I wish it was that cheap at the parts stores here lol, a 5qt jug is about $35 for the 5w30 synthetic

 

really? it's almost always on sale at my Advance.

 

tbh I haven't shopped around for it much...there's a Pep Boys a few blocks from my house that I just go to out of convenience. I might try Amazon though next time, probably cheaper

damn just checked Amazon and it's $22 on there

 

Ultra is $19.99 on Amazon and Walmart

 

I do have a Wally World not far from me, might swing by there and check it out

 

I've been wanting to give Super Tech a try. Can't be too bad considering they have to meet API standards. The try out will go in my old Chevy though both motor and gear oils. I'll see how that goes.

 

It tested well in the video @Wulf posted a few posts back, not as high as Amsoil or Pennzoil but still in the running, and you definitely can't beat the price.

 

I remember seeing Super Tech gear oil in gallon size for like $15.

 

I'm running super tech oil in my Tacoma and Lexus engines, Tacoma diffs, and my F250 diffs. No regrets.
