2010-2024 Toyota 4Runner Oils & Fluids

The 1GR-FE's reputation for going forever is not accidental — it rewards proper maintenance and punishes neglect in proportion to how long the neglect ran. Keeping every fluid in the truck at the right spec for what the engine and drivetrain actually need is what 2010-2024 Toyota 4Runner Oils & Fluids cover, from engine oil through transfer case and front and rear differential.

 

Full-synthetic engine oil is the right choice for the 4.0L regardless of use, given the wide temperature range it operates across and the elevated heat load during towing or long low-range trail days. Differential fluid in both axles should be changed more frequently than the published maximum on 4Runners doing water crossings since both axle breathers can take on moisture during a deep crossing.

 

Keeping every fluid in the fifth-gen at the right spec is the foundation everything else rests on, and 2010-2024 Toyota 4Runner Oils & Fluids cover all of it. The full engine performance category is at 2010-2024 Toyota 4Runner Engine Performance Parts, cold air intake options are at 2010-2024 Toyota 4Runner Cold Air Intakes & Air Filters, and cat-back exhaust options are at 2010-2024 Toyota 4Runner Cat-Back Exhaust.
