I bought my Almasol from Rick's.

I think most of the Amsoil users choose Severe Gear 75W-90 for the diff.

 

^ Correcto. That is what i used last week for my diff change.
Stuff is pretty thick, leave it out in the sun while you lay out tools and jack the car up to get it a little bit less viscous.

 

I changed mine last week and used the Amsoil Severe Gear 75-115.
Looking forward to some great results.

 

Hmmm...So should I get the 75W-90 or the 75-110? I live in San Diego, CA

What do most s2k users from Cali use?

S2K-lester, I think it's a no-brainer to go with the 75W-110 if the weight is available ... even if you lived in a cooler climate.

I am bent on trying Chevron's Delo gear oils and neither their conventional nor their synthetic is available in 75W-110 so I'm stuck deciding between 78W-90 or 75W-140.

Same for my back-up choice of Lubromoly: 75W-90 or 75W-140.

I may well be using the Amsoil gear oils 2-3 years from now ... and I would definitely use the 75W-110 in my AP2.

 

sounds good, Ill go with the 75-110 then

 

is it better to use 75W-90 or 75W-110 in a really hot climate like my country (Saudi Arabia)?

and which brand do you think is the best? having in mind my car is boosted (if it makes any difference)

 

in Israel we use a lot for a few years Redline 75w90 on drifting&tracking Miatas - so far no problems whatsoever.
but in SA temps are easily 10 degr higher than here....

(for gearbox we use Redline's MT90)

 

buzz944, as temps and horsepower/torque go up, your weight/viscosity should also ... it's just a matter of degree. I think the 75W-110 is a no brainer there as well. I'm not sure I'd go the next step with an 85W-140 without a UOA telling me the thinner fluids were lacking.

Hard to know what brands are available there. Maybe use Amsoil Severe Gear or Red Line Oil Shockproof? The Shockproof has a TON of molybdenum disulphide in it ... not sure of its effects on the limited-slip diff.

Croc, Interesting to hear that you use Red Line Oil MT-90 in your gear box as it is significantly thicker than OEM spec ... and you're not much warmer than the southern third of North America. I'd mix Red Line Oil MT-90 and MTL and see if you can't get an easier shifting action ... maybe 80/20, 70/30, etc ... until you find the best balance.

Or do the same with Amsoil MTG and MTF which are the Amsoil equivalents to the 2 Red Ljne Oil fluids.

One pretty firm rule when mixing is to stay with the same brand so the additive package works more harmoniously. A little additive clash isn't likely to do damage ... but protection can be compromised over extended drains.

Update on my situation: 1 case of Chevron Delo 80W-90 is on its way to me!

I'll be using this in my AP2's diff for about 10,000 miles then I'll drain and to a UOA. Not sure what we'll find out about the fluid with the fluid in use merely 10K.
