How does Bar’s Leaks Engine Repair work?

Engine Repair contains a combination of the best performance additives to repair the most common oil-related problems. Engine Repair restores lost compression and power, reduces noise and oil consumption, while improving the performance of worn cylinders, rings, bearings, and seals.

Will Bar’s Leaks Engine Repair clog my oil filter?

No, Bar’s Leaks Engine Repair does not contain any sticky substances that would clog or damage your oil filter. It works chemically to stop leaks in gaskets and seals.

Will Bar’s Leaks Engine Repair work in synthetic oil?

Yes, Bar’s Leaks Engine Repair is compatible with ALL types of engine oils, including petroleum, synthetic and high-mileage formulas.

Isn’t Engine Oil Enough?

Engine oils are generally used to reduce friction between moving parts. In addition to lubricating, motor oil must cool, provide corrosion protection and is a method of removing contaminants. As lubricants degrade, their properties change, leading to increased friction and wear. Over time the natural wear that occurs inside the engine causes reduced oil pressure, loss of compression (power loss), lower fuel mileage, oil consumption (leaks & smoking) and noise (knocking & ticking).

Can I add to existing oil?

Yes, remove engine dipstick and check oil level. If oil is low, remove oil cap and install entire contents of the two chamber bottle. Do NOT overfill. Top off with manufacturers recommended engine oil as needed. Reinstall dipstick and oil cap. Drive/idle engine for 10-15 minutes.

If I install more than the recommend amount, will it work faster or better?

No, we have formulated our product to work best at the suggested dosage amount.

What are the dosage recommendations?

One 15.5 oz bottle of Bar’s Leaks Engine Repair, part number 1000, treats 4 to 6 quarts of oil.

If first application does not completely stop my leak, may I add another bottle?

Yes, in engines with seriously damaged components, a second treatment may be required. In this case, it is suggested that the oil and filter be changed, and a second application of Engine Repair be added.

How long does it take to start working?

Bar’s Leaks Engine Repair starts working the minute you install and start driving the vehicle. You will usually see results in about 250 miles or three (3) days of driving.
