Redline ShockProof Gear Oil for Front Axle?

Apologies if you have already found this link. It does at least show what specifications the AGCO product claims to meet.

Thanks for the link. I seen that PDF from AGCO previously. It does tell quite about their product. However, it will still be inferior to a true synthetic oil that is Group IV or V base stock, the Permatran 821XL is group II base stock. Pretty average oil used through out the industry. So there is room for improvement to use something better over it, especially in the HST or Front Axle, but especially in the HST. Most HST's fail due to heat caused by friction. In all HST's there is a decrease in performance over time, however, using a high grade oil will prolong a life of HST by decreasing heat.

Group II

Group II base oils are defined as being more than 90 percent saturates, less than 0.03 percent sulfur and with a viscosity index of 80 to 120. They are often manufactured by hydrocracking, which is a more complex process than what is used for Group I base oils. Since all the hydrocarbon molecules of these oils are saturated, Group II base oils have better antioxidation properties. They also have a clearer color and cost more in comparison to Group I base oils. Still, Group II base oils are becoming very common on the market today and are priced very close to Group I oils.

Group IV

Group IV base oils are polyalphaolefins (PAOs). These synthetic base oils are made through a process called synthesizing. They have a much broader temperature range and are great for use in extreme cold conditions and high heat applications.

Group V

Group V base oils are classified as all other base oils, including silicone, phosphate ester, polyalkylene glycol (PAG), polyolester, biolubes, etc. These base oils are at times mixed with other base stocks to enhance the oil’s properties. An example would be a PAO-based compressor oil that is mixed with a polyolester. Esters are common Group V base oils used in different lubricant formulations to improve the properties of the existing base oil. Ester oils can take more abuse at higher temperatures and will provide superior detergency compared to a PAO synthetic base oil, which in turn increases the hours of use.

since you're looking for quality, how does Mobil 1 full syn 75/90 compare to your Redline in terms of specs & price? just asking since you're considering....i'll prob go w/mobil 1 syn in my next vehicle gear oil change, but stick w/conventional 80/90w in tractor. i can't advise for HST fluid since i don't own nor ever will, but imho i'd just go w/sud2 if i did ....happy new yr.

You missed out Group III.
Definition:
Greater than or equal to 90 percent saturates and less than or equal to .03 percent Sulpher with a viscosity index (VI) greater than or equal to 120.
Confusingly products formulated with these types of product can, in North America, be described as 'synthetic'.

Yes, I chose to omit Group III. Since it's only a bit better than Group II. Most M1 oils use Group III and are labeled as a synthetic oil i.e. M1 5w-30, however there are some M1 oils that use a group IV stock such as the M1 0w-40 Euro care formula as well as Shell Rotella T6 is a group IV. Redline uses IV and V base stocks, but mostly V. Basically ultra premium synthetic oils made from the ground up.

I would actually consider it above average to very good. I would have no problem running their formulation as long as they have not downgraded their base stock to III. Here is a fun article regarding "best" gear oil. Unfortunately, it is sponsored by Amsoil - guess who won... they ranked M1 second right behind Amsoil.

Reality is that off the shelf item and not a premium exclusive oil like Amsoil / Redline work well in 99% of the applications they are intended for. Specs are similar, slight edge to Redline/Amsoil on paper, price winner is M1 for sure.

Kubota SUDT2 is a Synthetic Blend Groups II & III mix most likely. Amsoil 5w-30 is the only HST fluid that is 100% synthetic base stock, Redline does not make a hydraulic fluid for agricultural use.

Actually Group III base oils are considerably 'better' than Group II. A number of OEM specifications require Group III since stocks of the Group I and II types simply cannot meet the requirements, oxidation performance for example. The confusion regarding these stocks arises from the decision to permit them to be described as synthetic (in North America).

Well, Group III is that niche group for the oil industry so they can call something synthetic without it actually being formulated ground up from a synthetic base rather its been hydrocracked and label as synthetic in the USA. However, true "synthetic" oil is a Group IV or V base stock engineered always to be synthetic. Therefore, I omit Group III since yes it is better than I or II, but it is not a true synthetic engineered from beginning. If I have spend $8-9 per quart on Group III, I rather spend the extra $1-2 and just get the Group IV/V.

Human beings love to judge things we cannot see... it's our nature.

As a purist I agree with you about the use of the term 'synthetic' in that it should really be confined to Group IV and V. However, in North America it is not, and that is confusing to consumers. There is nothing wrong with Group III based fluids, in fact generally they are very good, but they do not have all of the same properties as for instance PAO/ester formulations, e.g. heat transfer, and low temperature performance. One has to decide for oneself whether the extra cost of a true synthetic is worth the extra expense, assuming that you can correctly identify it a such.
