Liqui Moly Pro-Line Gear Oil Leak Stop – 500ml Additive for Manual Gearboxes
Got a stubborn leak in your manual gearbox or diff? The Liqui Moly Pro-Line Gear Oil Leak Stop might just be your new best mate. It’s specially formulated for all manual gearboxes, drive shafts, and differentials. Just a heads-up though – it’s not suitable for fully automatic gearboxes or boxes with oil-bath clutches, so best to double-check your vehicle’s specs before cracking on.
So, how does it work?
This clever little additive gets poured straight into your gear oil—one 500ml can treats up to 10 litres. Once it’s in, it sets about sealing those pesky leaks that leave oil spots on your driveway or garage floor. Even better, it helps rejuvenate those rubber and plastic seals inside the transmission, keeping them supple and less prone to cracking. Don’t expect miracles overnight though; you’ll need to drive around 600 to 800 kilometres before you see the full sealing effect kick in.
Why go for this product?
Oil leaks aren’t just a pain in the neck for your wallet—they’re a right nuisance for the environment as well. This product tackles leaks head-on, meaning fewer drips and less mess to clean up. It’s professional-grade stuff, trusted by the experts to get the job done without any faff. Plus, it’s dead easy to use—no complicated tools or setups required.
When to reach for it
- Spotting oil drips beneath your car’s manual transmission? This additive can help seal those leaks.
- Great for giving manual gearboxes and differentials a bit of TLC, keeping seals soft and flexible rather than brittle and cracked.
- Ideal if you want to dodge expensive repairs or stop your garage floor looking like an oil slick.
That said, don’t expect it to work wonders on seals that are completely knackered. It’s more of a preventative measure or a handy repair aid. When in doubt, have a quick word with your mechanic before giving it a go.
To sum up, Liqui Moly’s Pro-Line Gear Oil Leak Stop is a cracking little product that keeps your manual gearbox and diff running smoothly without the hassle of oil leaks. A small bottle with a big impact—say goodbye to messy oil stains and the worries that come with them!
