## Overview

BlueDevil Rear Main Sealer is an 8-ounce liquid additive designed to permanently fix rear main seal leaks by restoring rubber seals while driving. Compatible with all engine types and oils, it offers a safe, easy-to-use solution trusted by thousands to stop oil leaks without costly repairs.

## Description

BlueDevil Rear Main Sealer is a product designed to fix leaks in the rear main seal of an engine. The rear main seal is a critical component of an engine, as it helps to keep the oil inside the engine and prevent it from leaking out. Over time, the seal can become worn or damaged, leading to leaks. Bluedevil Rear Main Sealer is formulated to be a non-particulate sealant that can mix with the engine oil and flow into the damaged areas of the rear main seal, creating a permanent seal. It is designed to work with all types of engine oil and can be used in both gasoline and diesel engines.

Review: As advertised - I used this 2 times now the leak never came back. The first time I used it I was really sceptical about this product still leaking for two days but as I drive along the leak suddenly disappeared. So when I did my oil change I pour another bottle no more leak up to now. I think it does its job kudos to the seller and kudos to bluedevil.
