75W-90 is the one for our transmission.
Cool thanks brotha! And I think I read in manual it's 3 pints or something that it requires if I drain and fill?

5w30 engine oil is pretty close to 75w90 transmission oil in terms of thickness. they measure differently.
I had a jeep required 5w30 as transmission oil and ATF as transfer case oil.
The other thing is make sure its the right grade. GL-5 will react with brass syncros in many transmissions. That's why most transmissions require GL-4.

My dad had a 95 Silverado he sold a few years ago that had amsoil from day 1. It had 240k on it when sold, and the only thing ever done to that engine was a water pump replacement. I think he told me every 12k miles he changed the filter and added a quart....
Oh, yeah...."well my Dad" had a 2001 Toyota Avalon that had over 350,000 miles on it. He just took it into the local oil change shops and had them put in the regular conventional Pennzoil or Quaker State for its whole life.

Point is these oil debates are mostly pointless. Stick with a quality brand, stay with the manufactures spec and weight, change at manufacturer recommended intervals...

Worry less, drive more.

Comparing a toyota economy sedan to a performance engine that has entirely different requirements is not even apples to apples.

^ This.

A DD family sedan's oil requirements are going to be a lot different than a performance vehicle, especially one that has its tach reach the limit a lot.

I agree with you. A Toyota Avalon engine is not the same thing as a 5.0 Coyote or 2.3 EcoBoost.
I'm only trying to convey that 99% of these oil threads have no real data to validate if "oil A" is better then "oil B".

I actually fall into the camp of over thinking which oil to use.
I'm a car enthusist, I 100% get it....I want to run the best oil I can for my Mustang.

If you study VOA and UOA on sites such as bobistheoilguy.com you realize that most oils within a given spec are very very similar regardless of brand.

But, I still try to find some differentiating real data to validate why to choose brand A vs brand B.

For me Pennzoil ULTRA Platinum 5W-20 is the oil I choose to run in my Coyote. Why? It has a great additive package (verified by VOA) and performs very well on UOA tests and the NOACK (% burn off) test.

To quote my earlier post (#42):

Pennzoil Ultra Platinum and Pennzoil Platinum base stock is made from Natural Gas. This is a new patented process that makes Pennzoil Platinum products very pure and also different.

Shell Oil claims that Pennzoil Ultra Platinum keeps pistons 25% cleaner then the leading synthetic oil (Mobil 1).

BMW used to use Castrol....but since 2012 they have used relabeled Pennzoil Ultra as their "BMW brand oil"
SRT recommends Pennzoil Ultra
Ferrari recommends Pennzoil Ultra
Hennessey Performance recommends Pennzoil
Some of the above is probably just marketing $$ at work.

BUT, real numbers are where it counts, Right!?
The Volatility Burn Off (NOACK) [% mass loss, 250 degrees C or 482 degrees F @ 1 hour] tests are a good indicator on the quality of the base stock. How much of the oil burns off in extreme temperature conditions?

The NOACK tests are very good on Pennzoil Platinum Products:

Pennzoil Ultra = 6.6%
Quaker State Ultra (Quaker State, like Pennzoil is owned by Shell Oil) = 8.8%
Amsoil OE = 10.9%
Royal Purple = 10.9%
Mobil 1 = 10.1%
Castrol Edge = 11.1%
http://www.pqiamerica.com/March2013P...sallfinal.html


6.6% burn off for Pennzoil Ultra Platinum vs 10.1+ % burn off on the others listed above. That's a big advantage for Pennzoil Platinum in my book.
Pennzoil Ultra also tests very well on UOA data posted on bobistheoilguy.com.

Also, Pennzoil will warranty all oil lubricated parts of your engine for 500,000 miles if you use Pennzoil Ultra! You just have to start only using Pennzoil Ultra before 75,000 miles. See their website for the details.

All this PLUS the fact that Pennzoil Ultra is available for $22.47 for 5 quart jugs at Walmart.com ($4.49 quart).

Why pay higher prices for other synthetics when Pennzoil Ultra tests better, has a great warranty and is cheaper??
