In another post, there was some discussion about Citgo Dex III. Is this good stuff compared to Castrol/Pennz/Valvoline, etc? Just wondering why Citgo / Harvest King / Mystic fluid was recommended in the "best dex III" post.

it was discussed as a low-cost alternative OTC to Specialty Blenders such as, Schaeffers, Redline, Amsoil, Mobil, and Royal Purple, etc.
As I mentioned in another post, our sponsors, including Schaeffers, Redline, Amsoil, Mobil, and now Royal Purple, are preferable to any OTC Dexron III not because they are sponsors, but because their selection of base oils and additive packages are not based on the economies of sale, but on quality and economy of scale.

Understood. However, is there anything that makes Citgo stand above other OTC $1-2/Qt. dino oils, or was that just a name you pulled out of a hat? I have no doubt that a quality oil from one of our sponsers is a better bet, but I am strictly talking about cheap OTC dino stuff.

Nothing personal, but I don't usually throw down product names with which I am not familiar.
I mentioned it because some rancher friends of mine buy 5 or more-gallons of HK DIII/Mercon at a time for their farm and ranch truck transmissions, and have had good service with these fluids. If you buy in 5-gal. quantities, cost is approx. $1.25/qt.
They use a 4 cSt parafinnic base fluid with VII's and the ATF DIII add pack.

Hope I didn't offend... that was not my intent.. I just didn't know if you were citing Citgo due to it's low price, or if it really was good stuff compared to the other "cheap" brands.
Thanks for clearing that up.

The above figure was WITH tax.
Cost per quart in quantity mentioned is $1.14.
Don't expect this fluid to last much past 30,000 miles.
Alright... if this is true, what is a good 50,000 miles fluid? Are ALL cheap dinos done by 30k miles?
I don't know much about automatic transmission fluid, so please educate me. I am looking to do a drain-and-fill on a GM FWD trans. With a pan drop, I can get 7 of 11 quarts replaced. What would be the best fluid? Let's take cost and OTC requirements out of the picture for a minute.

I think if you have a daily driver and run under normal service situations, then changing your fluid within 30,000 miles, the HK DIII/Mercon would be fine. The reason I say this is because of the additive package. If you are pulling loads or running in exteme heat at high speeds, then you are running in severe service conditions, and you may want to change fluid in less than this interval.
Now synthetic fluids have longer lasting (and more expensive) additive packages because they are expected to have > 50,000 mile longevity.
This is one of the reasons why the GM DIII(H) spec is on the scene. They expect these Factory fill fluids to last approx. 100,000 miles in NORMAL service, whatever that is defined to be. These fluids will have to be synthetics or Group II/IV blends.
