Bardahl T&D Additive for Gear Oil – Transmission and Differential Treatment, 250 ml
Noticed your car’s transmission or differential sounding a bit grumbly or feeling a tad stiff? A dash of Bardahl’s T&D additive might just be the ticket. It’s designed to go straight into your gear oil, smoothing out those gear changes and giving your components a bit of extra protection against the daily grind. Most folks don’t give much thought to what’s lurking in their gearbox oil, but this little bottle really does pack a punch in keeping everything running sweetly and quietly.
Why bother with a gear oil additive?
Transmissions and differentials have it rough – they’re under constant pressure and heat, which takes its toll on both the oil and the metal parts. Over time, friction wears things down, leading to noisy gears, rough shifts, or even leaks. This additive steps in by boosting the oil’s protective powers, cutting down friction and wear, and generally making your gear changes feel a whole lot smoother. It’s especially handy if you’re hearing a bit of racket or feeling some stiffness but aren’t quite ready to splash out on pricey repairs.
Simple to use, brilliantly effective
Each 250 ml bottle is perfectly sized for a typical gear oil change – just pour it in when you’re topping up or switching your oil. No messing about with complicated measurements or extra tools. Bardahl’s a name you can trust; they’ve been in the game for years, so you know this stuff is up to snuff. Just a heads-up, it’s strictly for motor vehicles, so keep it for your car or van’s gearbox rather than your lawnmower.
