How can you be losing oil if you have no obvious leak?

Imagine this: you’re driving down the road, and suddenly your oil level light comes on. There’s is no puddle under your car, and you’ve never seen evidence of any kind of leak. The bad news is that oil loss can happen for a multitude of reasons, and a leak is just one of them.

The good news – we can help your oil loss situation, whether it’s a leak or not.

For now, let’s assume it’s not a leak. So what’s going on?

How can my car be losing oil if I have no leak?

When your car begins to lose oil in the course of everyday driving and there is no leak, you’re probably burning it away. Though you may not see any visible signs of leakage on the ground, oil loss can still happen. This typically happens because as a car ages, engine seals harden and shrink from the plasticizers being removed over time. It’s normal, but it’s a pain.

So does that mean I’m burning oil?

Probably, yes. Oil burning happens when older engine parts allow oil to seep into the combustion chamber. A telltale sign is the bluish smoke coming from your exhaust. But even if you don’t see any signs of blue smoke, you can still be burning oil in trace amounts. Over days and weeks, this leads to low oil levels, and eventually your oil indicator lighting up on your dashboard.

Oil loss isn’t something to sleep on. Losing too much oil can result in serious engine damage and expensive repairs, especially with high-mileage cars and those that see a lot of stop-and-go driving or driving in harsh conditions. 

So what can I do, short of taking it to a shop or dealer?

Bar’s Leaks has been known for effective, affordable leak repair for over 75 years. We have a few oil leak repair solutions, but the most powerful among them is our professional-grade Oil Seal Engine Oil Burning & Leak Repair (most often referred to as Bar’s Leaks Oil Seal, part number OS-1).

This is our strongest formula ever to stop main seal, valve seals, timing cover seal, cam seals, crankshaft seal, oil pan, valve cover and all other oil sources of oil leaks, no matter what size.

What does Bar’s Leaks Oil Seal do, and how does it work?

This product is incredibly effective against oil leaks, but what about oil burning? We have that covered too. 

There could be two possible reasons as to why your vehicle is burning oil. (1) It may have an oil leak or (2) it could be burning oil during the ignition cycle. One common problem is if the cylinder walls are allowing oil to leak up from the bottom of the engine, past the piston and into the combustion chamber. So when the fuel ignites, the oil does as well, and then expels it out as exhaust. Before you know it, you’re dealing with an oil burning problem. 

The good news is that with a single application of Bar’s Leaks Oil Seal, those problems will be history.

Will Oil Seal work in my car?

Short answer: almost certainly.

Your vehicle is a good candidate for Oil Seal if it does not consume more than one quart of oil per day. We have designed this product to work in all gasoline and diesel engines including turbocharged, EcoBoost, hybrid and even racing engines. This covers 3, 4, 5, 6, 8 and 10 cylinder engines in all cars, trucks, vans and SUVs. Our product can also be used in heavy-duty applications referencing the appropriate dosage level. 

This product doesn’t just work on cars, either. It also applies to a wide range of other motor applications too: tractors, boats, RVs, motorcycles (including wet clutch), ATVs, and lawn equipment.

Oil Seal’s main technology

Bar’s Leaks Oil Seal is a professional-grade product specifically formulated to tackle every kind of oil leak, burning and consumption issue. Synthetic polymers combined with premium seal restoring additives work together better than all other regular treatment products to create a long lasting repair. These polymers also fill in small scratches and wear marks preventing oil from passing and being burned. All of this centers around a few main chemical components:

  1. Seal restorer – restores seal size, flexibility and elasticity lost due to engine heat, age and high mileage.
  2. Seal polymer – chemical polymers work where other stop leaks fail to seal leaks that is caused by normal engine wear. This includes grooves worn in the crankshaft seal mating surface. The polymer forms a film between the seal and the crankshaft, preventing leaks.
