Ordered some LE1605 from HTG.com and was wondering if anyone else uses it up in the Northwest. I don't think it gets cold enough up here to worry about the viscosity increasing too much, it would just make me feel better if someone in the northwest uses this same fluid. Thanks guys!

 

ah, that's backwards ...... bigdoc211 splits hairs it.

 

I've been using since 11k miles and now have 53k miles. It's been great.

When changing my diff fluid I put the bottles of the LE607 infront of a space heater for a few minutes so then when I use the hand pump to pump the fluid into the diff it's a lot easier.

I also garage my car so it doesn't sit outside during the snowy days.

 

I've only used LE607. Haven't tried the new LE1605. My diff hasn't gone pop yet, & if it does I won't blame it on the fluid.

I barely researched LE1605 & found this thread. They claim that LE1605 replaced LE607, so I presume their properties are similar enough for this hair splitting discussion.
Unless you're driving around in -11 degF weather, I wouldn't sweat it. If you are driving around in that weather you probably can't sweat anyway.

 

... unless you gots the bald tires

 

At that point the sweat will be transferred directly onto the seat.

... While Greenie passes you doing 3 mph in the snow.

 

I swapped in LE1605 about 1000 miles ago. No complaints, but I haven't hit any real cold weather yet.

It is a direct replacement for the LE607, which is no longer made. The labelled weight has been updated to be in line with the new SAE requirements, but it is still the same weight as it was before. Many people were confused since the new one is rated as a higher weight than the LE607 formulation.
