Battle Garage Racing Service Maintenance Guide

Welcome to the Battle Garage Racing Service Maintenance Guide! This guide is specifically tailored for FA20 and FA24 BRZ Gen 1 and GR86 Gen 2 enthusiasts who want to change their engine oil but are unsure about the best oil viscosity and brand to choose for their modified vehicles. We understand that choosing the right oil can be a daunting task, so we've simplified the process by offering Maintenance Oil Kits that contain everything you need for a worry-free oil change.

Our Maintenance Oil Kits include the precise amount of oil required for your FA20 or FA24 engine, eliminating the need for extensive research on your part. We've also taken into account the additional oil used by oil coolers, commonly utilized by HPDE competitors and dedicated track enthusiasts. Our kits feature reputable brands such as Subaru OEM, MOTUL, AMSOIL, and more. Each kit also includes an oil filter and a drain plug crush washer for your convenience.

For those seeking a bit more edge, we've introduced the Casual+, Canyon+, and HPDE+ tiers, delivering that extra performance boost without requiring a leap to the next level.

Let's break down our Maintenance Oil Kits based on your driving habits and vehicle modifications:

Casual: Recommended for Daily Drivers and Occasional Canyon Runners

These kits are ideal for enthusiasts who primarily use their vehicles for daily commuting and occasionally enjoy spirited drives through the canyons. If you're not pushing your FA20/FA24 too hard, we recommend sticking with the factory recommendation of 0W-20 oil. This oil viscosity strikes the right balance between daily driving and occasional spirited runs, ensuring your engine's longevity and performance.

Canyon: Recommended for Frequent Canyon Runners

If you're a frequent canyon runner, our Canyon Kits are tailor-made for your needs. With the demanding conditions of canyon drives in mind, we recommend using 5W-30, a thicker viscosity oil to enhance engine protection. While these kits are well-suited for mostly stock vehicles, for those with an oil cooler installed, we recommend acquiring an additional quart of oil to guarantee optimal performance.
