Let me start by saying, when you’re dealing with leaks in your vehicle, especially from something as crucial as the rear main seal, it can feel like a big deal.
I found myself in this situation with my car recently, and the thought of forking out thousands for a repair wasn’t something I was excited about.
That’s when I stumbled upon BlueDevil Rear Main Sealer. After researching and reading numerous user reviews, I decided to give it a go.
Now, if you’re here because you’re wondering if this product is right for you or if it actually works, you’re in the right place. In this review, I’m going to share my experience, break down the pros and cons, and compare it with other sealers on the market.
My BlueDevil Rear Main Sealer Experience
I’ll be honest. When I first heard about the BlueDevil Rear Main Sealer, I was skeptical.
I’ve always been cautious about “quick fixes” for cars, especially anything that promises to seal leaks magically.
But after reading some reviews, I figured it was worth a shot. What’s a $20 bottle compared to a $2,000 rear main seal repair?
I poured the BlueDevil into my engine as per the instructions, which was straightforward enough.
You don’t have to be a mechanic to figure it out. After driving my car for a bit, I didn’t see immediate results, but I wasn’t discouraged.
Many users reported it took some driving before they noticed a difference.
After a few hundred miles, I noticed the oil spots on my driveway were starting to shrink. This was promising! By the time I hit the 400-mile mark, the leak had all but stopped. I was genuinely impressed. What would have been a costly repair job was seemingly fixed with a simple product.

How BlueDevil Rear Main Sealer Works?
For those unfamiliar, the rear main seal in your car is designed to keep oil from leaking where the crankshaft exits the engine. Over time, this seal can degrade or shrink, leading to leaks.
BlueDevil Rear Main Sealer works by flowing into the seal and restoring it to its original condition. It’s specifically designed to work with both synthetic and conventional oils, making it versatile for a wide range of engines.
This product doesn’t contain harmful chemicals like petroleum distillates, so it won’t damage your engine seals. Instead, it’s formulated to be safe for your vehicle while effectively sealing the leak.
Pros of BlueDevil Rear Main Sealer
Based on my experience and what I’ve gathered from others, there are several standout benefits to using BlueDevil Rear Main Sealer:
- Easy to Use: You don’t need any special skills or tools. Simply pour it into the engine oil, and you’re good to go.
- Restores Seals: It doesn’t just temporarily cover the problem. It works to restore dried and cracked seals.
- Compatibility: Works with both gasoline and diesel engines and all types of oil, making it suitable for most vehicles.
- Affordable: Compared to a costly repair, this product is a bargain at under $20.
Cons of BlueDevil Rear Main Sealer
No product is perfect, and BlueDevil is no exception. Here are a few downsides I noticed:
- Not a Permanent Solution: While it works well initially, some users report that the leak can return after some time, especially if the seal damage is severe.
- Effectiveness Can Vary: Not all leaks are created equal. If your rear main seal is too far gone, this product may not be able to completely stop the leak.
- Takes Time: It doesn’t work immediately. You need to give it time and drive your car for several miles before seeing results.
Tips After Using BlueDevil
Once you’ve used the BlueDevil Rear Main Sealer and seen positive results, it’s essential to take steps to maintain your vehicle properly. Here are a few tips I’ve found useful:
- Monitor Oil Levels: Even after the leak stops, keep an eye on your oil levels to ensure everything is working correctly.
- Regular Oil Changes: Change your oil according to your vehicle’s maintenance schedule to prevent any future issues with your seals.
- Drive Consistently: Drive your vehicle regularly after using the sealer to allow the product to fully circulate through the system.
- Inspect for Other Leaks: If your rear main seal was leaking, it’s worth checking if other seals or gaskets are starting to wear out too.

Comparing BlueDevil Rear Main Sealer With Other Brands
When it comes to sealers, BlueDevil isn’t the only product on the market. I’ve tried and looked into a few others for comparison, and here’s how they stack up:
Bar’s Leaks Rear Main Seal Repair
- Effectiveness: Bar’s Leaks is another well-known brand, but many users report it doesn’t last as long as BlueDevil.
- Price: Slightly cheaper than BlueDevil, but you might need to use more of it over time due to its shorter lifespan.
- Ease of Use: Both are easy to use, but Bar’s Leaks tends to be a bit more watery, making it easier to pour.
Lucas Engine Oil Stop Leak
- Effectiveness: Lucas Engine Oil Stop Leak works well for smaller leaks, but it doesn’t have the same long-lasting effect as BlueDevil.
- Price: Lucas is similarly priced but often requires more frequent use.
- Compatibility: Lucas is also compatible with synthetic and conventional oils, but it’s better for smaller leaks or for preventative measures.
ATP AT-205 Re-Seal
- Effectiveness: ATP AT-205 Re-Seal is known for working quickly, but it’s not specifically designed for rear main seals. It can help with other seals, but results on rear main seals are mixed.
- Price: More expensive than BlueDevil, making it a less attractive option.
- Ease of Use: ATP is easy to use, but because it’s a general-purpose sealant, it might not work as effectively for rear main seal leaks.
Is BlueDevil Rear Main Sealer Worth It?
In my experience, BlueDevil Rear Main Sealer is a great product if you’re looking to save money and stop a rear main seal leak without tearing your engine apart.
It’s not a miracle cure, but it can certainly help prolong the life of your car and stop those annoying oil spots on your driveway.
However, if the leak is severe, it might be a temporary fix, and a more permanent repair could eventually be necessary.
That said, it’s worth trying, especially if you’re not ready to commit to an expensive repair.
Just keep in mind that the product’s effectiveness can vary depending on the condition of your engine and the severity of the leak.
Where To Buy BlueDevil Rear Main Sealer?
Before we jump into my experience, you’re probably wondering where you can purchase the BlueDevil Rear Main Sealer. The product is widely available online and at most auto parts stores.
I got mine on Amazon, where it’s frequently stocked, and shipping was quick.
If you prefer a more hands-on approach, you can check with your local auto parts retailer like AutoZone or O’Reilly Auto Parts. Both of these outlets usually have it on the shelves, and you can even ask for advice from the staff.
