Purpose and Specifications

ELF Tranself Syn FE 75W140 is a fully synthetic transmission oil designed for heavily loaded gearboxes, axles, and differentials in trucks and heavy vehicles. It meets API GL-5 and SCANIA STO 1:0 standards, providing extreme pressure protection that keeps gears smooth under severe loads like towing or off-road use.

This 1-liter bottle delivers practical benefits: flows easily in cold weather down to -40°C for quick starts, stays thick up to 150°C to prevent breakdowns, and resists breakdown for extended drain intervals up to 200,000 km or 24 months in normal fleet service. Its anti-wear formula cuts gear friction, saves fuel, and protects against rust even with water exposure.

• Perfect for manual transmissions, hypoid axles, and differentials in demanding conditions.
• Key perks: Smoother shifting in cold, stable heat performance, longer oil life.
• Shelf life: 5 years unopened in cool, dry storage.

When to Use / Replace?

Use ELF Tranself Syn FE 75W140 in high-load applications like construction trucks or long-haul semis where standard oils fail early. Ideal replacement if your manual calls for GL-5 75W140 spec, especially in freezing winters or hot summers.

Replace every 150,000-200,000 km or 18-24 months, or sooner if you notice hard shifting, unusual noise, or contamination. Check levels monthly in extreme conditions.

FAQ

Q: Can I use this in my passenger car differential?
A: Yes, if it specifies API GL-5 75W140; great for hypoid gears in SUVs or performance cars under heavy towing.

Q: Does it work in cold climates?
A: Absolutely - the 75W rating ensures easy flow at -40°C, making gear shifts smooth on winter mornings.

Q: How long does it last compared to regular oil?
A: Up to twice as long, often 200,000 km, thanks to superior shear stability and thermal resistance.
