Oil Stop Leak Additives – Do They Work?
So you’ve just noticed the tell-tale stain of oil where you usually park your car and, on further inspection, the level’s down. There’s no doubt. You’ve got a leak. Now what? One course of action is to reach for a stop-leak product – but do they actually work and are they worth it?
Firstly, let’s have a look at what causes an oil leak from your engine. While there can be a lot of reasons, the most common is a fault with engine seals – gaskets, O rings, and other seals – giving up the ghost to varying degrees due to age, heat, mileage, and/or pressure, causing said seals to shrink, harden, or dry up. This creates a space between the seal and what it’s meant to be sealing, allowing oil to seep out.
Stop-leak additives are designed to prevent that by reducing the amount of oil getting out of those spaces. Early versions used ‘mechanical’ methods – clogging the holes with nut shell particles suspended in castor oil. Others used sawdust and teeny bits of metals. As you can guess, nut shells, saw dust, and aluminum sprinkles aren’t exactly ideal to have floating around in your engine.
The next generation contained petroleum distillates to cause the seals to swell and therefore stop the leak, but these didn’t last long and the leak would return, better than ever. Today, the best stop-leak additives are actually absorbed by the seals and then expand the seals, returning them to their original shape, flexibility, and size.
Now that we’ve got that on board, let’s cut to the chase – do they work? The short answer is . . . sort of. While the new formulas will stop those leaks in many situations, they aren’t a permanent solution. The leaking seal will, sooner or later, need replacing.
Technical Features of Oil Stop Leak Additives
| Feature | Description |

Types of Oil Stop Leak Additives
| Type | Description |
|---|---|
| Particle-Clogging | Uses particles to block leaks; can cause long-term engine damage |
| Absorbent Formulas | Penetrates seals to rejuvenate them; safer for engine health |
| Petroleum Distillates | Older formulas that can deteriorate seals over time |
| Plasticizers | Chemicals that restore rubber seals to original flexibility |
Oil leaks can be a nuisance, or they can be the forerunner of something catastrophic and need to be looked at. We reckon that’s best done as soon as possible. We also recommend that any oil leaks be looked at by a fully qualified, local mechanic on AutoGuru.
Common Causes of Oil Leaks
Finding oil spots under a parked vehicle can be both worrying and stressful for any vehicle owner. If the seal’s leak is small, oil may start to accumulate on the underside of the engine. But as the leak gets bigger, the oil leak will become visible in the front side of the engine. Regular maintenance and routine oil changes minimize the issues associated with oil seals and potential oil loss.
