We prefer to replace the terminals with similar-to-stock (Subaru does not sell the negative terminal except as part of it's sub-harness): https://www.buyautosupply.com/products/k13101-toyota-gm-style-battery-terminal-kit-positive-negative.html We cut off the factory Subaru crimped negative and crimp/heat shrink a lug to the cable for use with these terminals from BAS. These retain the stock look and feel and 10mm tooling of the OEM terminals. Use of quality terminals, some form of protectant (grease, spray, etc), and NOT torqueing them till you break the plastic around the terminal and cause the battery to leak are key to success here.

We don't recommend viscosities lower than 40 for older Subaru's. The main line on the block gets wallowed out to pretty ugly large clearances and this drops oil pressure to the already narrow rod bearings. We run Amsoil 5w40 for everything under ~400 WHP. Over that we go to either Signature 5w50 or Dominator 15w50 depending on use case. GD

Step 1: Install car lift

probably not the terminals, but the cable itself.. best option is to replace the entire cable - that changes the terminals as well
