Buying Guide

Match the required viscosity

Choose a fluid with the viscosity grade specified by your vehicle or equipment manual (e.g., 5W, 15W, or hydraulic grade) to ensure proper flow and component protection

Synthetic vs. mineral base

Synthetic fluids like long-life formulations typically offer better thermal stability and shear resistance, while mineral oils can be suitable for basic needs and cost-conscious users

Check OEM compatibility

Use OEM-recommended fluids or ones labeled for compatible systems (for example, transmission & hydraulic use for tractors) to avoid seal swelling or warranty issues

Consider pack size and frequency

Larger bottles and multi-packs (1L bottles or multi-packs) lower per-use cost for regular maintenance on multiple machines or frequent top-ups

Look for application-specific tags

Select products tagged for your use case—power steering, fork oil, transmission & hydraulic—to ensure additives and friction characteristics match the system
