🌡️ Carries heat away from moving gear surfaces 🛡️ Shields components under high pressure loads ⚙️ Prevents scoring, pitting, and early failure
Why It Matters
🚗 Car gear oil: smooth shifts, low drag, heat control 🚜 Tractor gear oil: extreme pressure and heavy load focus 🚚 Truck needs longer drain life under sustained stress
Cars vs Commercial
🌡️ SAE grades like 80W90 show cold and hot flow 💪 GL-4: best for synchronized manual transmissions 🔩 GL-5: use for differentials and hypoid gear sets
Read the Label
🔄 Check transmission type: manual, axle, or heavy-duty 🌏 Consider climate, dust, and terrain you drive in 💰 Balance gear oil price against drain interval and risk
