    Asian (PHOAT) Coolant vs Prestone POAT

    I've recently been researching coolant technology and decided I wanted to try and find an affordable way to get the type of coolants the manufacturers are specifying, rather than defaulting to the 1 gallon concentrated gold-colored Prestone I've been using that claim to work for "all makes and...

    Where did Conventional 80W-90 Limited Slip Gear Oils Go?

    Again, I'm stunned by how little attention is put toward oils (especially in stores like Napa, etc.) I have been using Valvoline High Performance Gear Oil 80W-90 for a long time, and all of a sudden they are gone. I found a random case for sale on Amazon, but generally speaking...they are...

The rear all have LSD in them...
