What Is At-205 Stop Oil Leak?

From my understanding, At-205 Stop Oil Leak is a specially formulated additive designed to reduce and seal oil leaks in engines, transmissions, and differentials. It works by rejuvenating old, hardened seals and gaskets, helping to restore their flexibility.

Why I Chose At-205 Stop Oil Leak

I chose At-205 because it’s known for being a professional-grade product with a reputation for effectiveness without harmful solvents or petroleum distillates. It’s also safe to use with all types of motor oils and synthetic oils, which gave me peace of mind.

Key Features I Looked For

  • Compatibility: I needed a product that works with various engine types and oils. At-205 claims to be compatible with both synthetic and conventional oils, which was important for me.
  • Non-toxic Formula: I wanted something safe that wouldn’t damage my engine or seals further. The water-based, non-petroleum formula of At-205 was a plus.
  • Ease of Use: Adding the product should be straightforward. With At-205, I just poured the recommended amount into the engine oil before my oil change.

How I Used At-205 Stop Oil Leak

I added At-205 to my engine oil during an oil change, following the instructions carefully. After running the engine for a few hundred miles, I noticed the leak had significantly reduced. It’s important to remember that this product works best on minor leaks and won’t fix severe gasket damage.

Things to Keep in Mind Before Buying
