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.
What other factors can contribute to oil leaks?
A few things can cause an oil leak that are not the fault of the seal or gasket. If the oil level is too high
(filled over the full mark) or the PCV (Positive Crankcase Ventilation) system is not functioning correctly,
leaks can occur. The PCV system prevents pressure from building up inside the engine and if it fails,
the pressure will cause the oil to leak. It is a good idea to clean or replace the PCV valve regularly to
prevent this problem. Oil leaks can also be caused by severely worn rings or a broken piston which
pressurizes the crankcase pushing out the oil. Lastly, which is mostly seen in cold areas that use salt
on winter roads, is a rusted out oil pan. For this issue, a pan replacement will be required.
Do I need to use Bar’s Leaks Main Seal Motor Oil Leak Repair with every oil change?
In most cases the oil leak issue will be repaired with a single dosage. However, for best results and to
prevent the problems from reoccurring, use with every other oil change.
Will Bar’s Leaks Main Seal Motor Oil Leak Repair clog my oil filter?
No. Bar’s Leaks Main Seal contains no particles to plug the leak. Instead, its technology relies on
special polymers and seal conditioners to stop oil leaks permanently.
My owner manual says not to use oil additives, is this product safe?
Yes, this product is completely safe to use in your vehicle. Keep in mind the main goal of the automotive
manufacturers is to get your car past the warranty period. These same manufacturers also have their
own private label chemicals which are sold and used at their dealerships. Older vehicles have different
requirements than a new car which allows them to benefit from certain oil additives.
