What Is Rislone Rear Main Seal Repair?
Rislone Rear Main Seal Repair is an additive designed to restore and rejuvenate worn engine seals, specifically targeting the rear main seal area. The idea is that instead of replacing the seal mechanically—a costly and labor-intensive task—this product softens and swells the existing rubber seal to stop leaks.
Why I Chose Rislone Rear Main Seal Repair
Replacing a rear main seal usually means a major engine teardown, which can be expensive and time-consuming. I wanted a simpler, more affordable solution, especially since the leak wasn’t severe yet. Rislone promised an easy fix that could be done during regular oil changes, which really appealed to me.
How I Used the Product
The instructions were straightforward: add the entire bottle to my engine oil, then drive the car for a few hundred miles to allow the product to work its way through the system and condition the seals. I made sure to use it during an oil change to avoid mixing it with old oil.
My Results and Experience
After about 300 miles, I noticed the leak had significantly reduced. It wasn’t completely gone, but the amount of oil on my driveway diminished noticeably. I think this product works best for minor to moderate leaks rather than completely worn-out seals. The engine ran smoothly, and I didn’t notice any adverse effects.
