BAR’S LEAKS

MAIN SEAL™

MOTOR OIL LEAK REPAIR

P/N: MS-1



Will Bar’s Leaks Main Seal Motor Oil Leak Repair work in all types of oil?

Yes. This premium quality synthetic blend works with all types of motor/engine oil including regular

petroleum, high mileage, synthetic blends and fully synthetic formulas.

Will Bar’s Leaks Main Seal Motor Oil Leak Repair work in my engine?

Yes. We have designed this product to work in all gasoline and diesel engines including turbocharged,

EcoBoost, hybrid and even racing engines. This covers 4, 5, 6, 8 and 10 cylinder engines in all cars,

trucks, vans and SUV’s. Even can be used in heavy-duty applications referencing the appropriate

dosage level. This applies to a wide range of other motor applications too: tractors, boats, RV’s,

motorcycles (including wet clutch), ATV’s, lawn equipment.

What are the dosage recommendations?

For most applications the entire bottle will be used. One bottle treats oil capacity from 5 quarts (4.7

liters) to 7 quarts (6.6 liters). Use ½ bottle for smaller oil capacity systems from 3.5 quarts (3.3 liters)

to 4.9 quarts (4.6 liters). In heavy duty applications and for larger systems use 1 bottle for every 6

quarts. In small engines including ATV, motorcycle, lawn equipment, tractors, etc., use approximately

5 ounces of Main Seal to every quart of oil capacity.

How does Bar’s Leaks Main Seal Oil Motor Oil Leak Repair work?

This product works in two ways to help solve most any motor oil leak.

1) A specially-engineered seal rejuvenating additive restores seal size, flexibility and elasticity lost

due to engine heat, age and high mileage.

2) An advanced seal polymer additive package works by building a polymeric film around the seal

to help prevent excess oil from bypassing the seal during normal engine operation.

What causes the seals to leak?

The most common cause of seal leaks is age and/or high mileage. The seal can also leak due to the

vehicle being stored for an extended period of time. Extended storage in particular causes drying and

hardening of the seal which leads to shrinking and cracking, and consequently leaking.

Main Seal Motor Oil Leak Repair Continued Page |2 What are the symptoms of an engine oil leak? Depending on the severity of the leak, the first thing you may notice is the oil level decreasing. If not corrected quickly, the oil pressure light may come on or oil pressure gauge may start reading low. The next thing that happens is spotting, where you will find oil spots, located on the driveway or garage. These spots are usually brown or very dark, almost black in color.
