amsoil or redline diff fluid 75w140

[Ron Mexico]

was planning to order redline but my napa dealer has this sad little dusty amsoil section back in the corner that contains 3 qts of 75w140.


so fanboys aside... go with the cheapest, right?

Amsoil recommends 75W-90 for our cars so, I recommend ordering something other than the 75w140 on the dusty shelf.

My owners manual says 75w140. We must have different cars.

I use amsoil severe gear 75w140 in my terminator cobra. First with stock diff and then with Torsen T2R About 6 years now. two or three track days/year. no diff cooler, it has never boiled over on track. change it out every other year just to be safe. no problems

We do have different cars. I apologize for not noticing that in your signature last night. :??:

Based on another check of the Amsoil site, 75W-140 is the viscosity they recommend for your application. That said, Amsoil and Redline both offer excellent product lines. I'm partial to Amsoil, but I don't think you can go wrong with either one.

DITTO only with Royal Purple Max Gear 75W-140 and a Detroit TrueTrac instead of the T2R diff, still running the same fluid from the day of the diff swap.(2006)

Thanks, everyone. I'll buy the amsoil if there's negligible price difference.

I wouldn't pay full price for it. Here is a link you can use to get up to 25% off everything you buy from Amsoil.

Both are excellent, flip a coin. It's definitely a case where you should go with the cheaper option.

I have always used Redline 75w90 in my 8.8's. I have no idea why Ford says 75w140 for the new 5.0's but it is still an 8.8 rear. I bought Redline 75w90 for mine. If it works fine in a 9 second fox, it will be fine in a '13 coyote

 

[Ron Mexico]

I ordered redline. Thanks, gents.

Stock fluid was disgusting after 7500 miles. It was gray and gritty.
