Lucas Oil 10279 Engine Stop Leak Additive – 3.785 Litre (One Gallon)
Got a pesky oil leak that just won’t quit? The Lucas Oil 10279 Engine Stop Leak might be just the ticket. It’s specially formulated to tackle those stubborn seal leaks, meaning less mess under the bonnet and fewer trips to the garage. This isn’t just any old additive — it’s a clever blend of Lucas’s signature additives and targeted base stocks that work together to restore your engine’s seals to good health.
How It Works and Where to Use It
Versatility is its middle name. Whether you’re running petrol or diesel, this stuff gets on with the job. But it doesn’t stop there — it’s also great for automatic transmissions, hydrostatic transmissions, and hydraulic systems. Just remember the dosages: for engines, aim for around 20% of the system’s capacity (so, one litre of the stop leak per four litres of motor oil). For transmissions and hydraulic setups, a 10% mix usually does the trick.
Why Choose Lucas Oil 10279?
Leaks aren’t just a pain — they can sap your engine’s performance and potentially cause serious damage if left unchecked. This product offers a straightforward, fuss-free fix that saves you both time and money. No need to faff about with complicated procedures or shell out for professional help; simply add it to your oil system and let it crack on.
