WM gets a lot lube products from WPp up north here. WPp stuff has worked better for me than Mobil HD80W90 - which really doesnt belong in a modern car.
Does it really matter who blended this stuff ? as it is ancient technology made with low grade, high volatility napthenic oil.
I was wondering who made it so I could track down the product data sheet. I couldn't find one. WPP also doesn't seem to post their sheets anymore either. They have a SDS portal on the website, but it's wonky at best, and I'm not looking for safety data. I was looking for kinematic viscosity data.
I looked quickly for a SDS but didnt find it online quickly.
Where is it going? general 3rd member lube in a garage grease pit?
Good questions? That is precisely the issue. I need a 80W-90 for front and rear DIFFs. The rear DIFFs all have LSD. Normally, I wouldn't buy such an oil, regardless of the application being used for, but only because I like to stick with what I know works. Lately, the market has changed and I can't get conventional oils with LSD additive and I'll have to add the additives to whichever conventional oil I choose. I wanted to make sure the viscosity isn't way out of range from the spec I like to use (Valvoline High Performance Gear Oil 80W-90 Limited Slip). Having said that, I don't even know where to begin evaluating whether an oil is made from a low grade or from high volatility napthenic oil. How can you determine the "grade" of oil it was made from?
