I hear the severe gear oil is not GL4 approved and they do not make the Series 2000 stuff anymore. Any other options from Amsoil?

Thanks

 

Yes, AMSOIL still offers AGT and ALU, both 80w-90 GL-4 lubricants. See my post in the Group Deals section for Dealer Cost offer.

 

Do you know how this stuff compares to the Series 2000 stuff? Also are these lubricants synthetic?

 

Ed,
I noticed on Amsoil's website that the AGT is rated as being GL-4 compliant but the ALU only made reference to the GL-5. Are you sure ALU is also GL5? ALU would be easier to buy as they come in the regular 946ml bottles where as AGT comes in a much bigger container.

 

My impression from Amsoil and BITOG posts was that the SVG can be used in GL-4 apps......

 

The question is, will 80W90 be light enought for a good Toronto winter night? I shied away from 80W90 in Chicago going for the extra 15 or so degrees in pour temps and peace of mind a 75W90 gear oil gives. JMHO.

 

Yup viscosity also had me worried with the 80w90 vs 75w90. Maybe it is wise that I stick to something else because of the temps we experience. Any idea on what the 80w90 ideal temp range is?

 

If it's synthetic, I think you are okay. If you compare an sythetic to a dino type gear oil, the synthetic keeps it's true viscosity MUCH better than dino. When dino gear oil is cold, man who knows what the viscosity starts out at.

 

The AGL pour temp is -33°C (-36°F) per their website. Windchills can beat that around here.

 

windchills arent factored on inanimate objects, windchills are only taken into account with mammals since we radiate heat and we get weak if too much heat is lost in a short amount of time. you want ambient temperature with regards to what oil you choose.

 

ALU is GL-4 rated...

 

Some of us have entered into this debate already. The SVG is labeled GL-5...it's not clearly labeled GL-2 thru GL-5 as were the oils it replaced. However, the Product Data Sheet for SVG says it "can be used in rear axles where GL-4 is recommended." I called AMSOIL Tech Services for clarification and they told me that although some folks were using this oil in transaxles, the best choice would be GL-4 AGT (or ALU) as the SVG contains a more "aggressive" additive package than the oils it replaced. For that reason I have not been recommending folks use SVG for our applications...

 

Unless Nissan specs something different for Canadian vehicles, my factory service manual for the '98 says use "GL-4 80-90 ONLY". That being the case, AGT or ALU should be your oil of choice.

 

forget this confusion and try some Redline MT-90.....smooth as butter shifts.....

 

Is there any major difference between either ALU or AGT?

 

ALU and AGT are essentially the same products, just targeted for different markets. They have the same performance specs, they are both approved for automotive GL-4 applications and the tech data sheet lists it as "AGT, ALU" with one set of performance numbers. AMSOIL Tech Services has told me that ALU contains slightly more water emulsifiers than the AGT since the ALU is marketed for marine applications, and that's the only difference...

Several folks have purchased a gallon of AGT and one quart of ALU...and that seems to be working out fine for them...

 

I used the term windchilll because it's a term most non technical people can understand. Does convection cooling of the transmission case in a very cold windy night sound better? The gear oil won't know the difference, only that it is cold. -33°C is a possibility in Toronto.

 

Great..

I am running the SEVERE SERVICE in my 2003 6 speed maxima... And now its the wrong oil? I spoke with tech service at AMSOIL and he said it should be fine running this..

Should i swap it out?

 

i got the gallon of ALU, and quart of AGT from ED, and it works fine, havnt had any problems so far, and yes they are BOTH GL-4

BTW- Buy from Ed, great seller, great customer service, and i got my oil 3 days after i ordered
