Just thought I would share how ATP worked in my car. I have/had multiple slow leaks from my engine. The leaks didn't amount to any more than a quart over an oil change. Just slow drips from multiple spots. I had been placing my car on cardboard in my garage to gauge the leaks.
My first attempt was PP HM 5w30 with substituting a quart of oil for a quart of Lucas Engine Stop Leak (3 qts oil + 1 qt Lucas ESL). After month, the leaks seemed to have slowed a bit, but none disappeared. Just looking at the spotting on the cardboard, it appeared to be less. After 1 month, I dumped that combination...
The combo I am running now is Mobil 1 High Mileage 10w40. My car has 140,000 miles on a Chevy V6. I also substituted 8 oz of oil for an 8 oz bottle of ATP 205 re-Seal. After 2 days of driving and leaving the car on cardboard over night, all but one of the oil spots has disappeared. I previously had 3 dime sized spots and 1 half dollar spot. The 3 dime size spots are gone and the remaining spot is down to roughly the size of a nickel. I would certainly consider this a success.
I am going to continue to run the 10w40 and I will probably add 1 or 2 oz of ATP reseal each oil change just to maintain the "fix." I may do two quarts of 5w40 plus two quarts of 10w40 in the winter just to help with the cold starting.
Just so we can get this out of the way... I am not a proponent of "fix in a can" in most cases. However, I am not going to tear apart the motor on a Chevy with 140,000+ miles on a rusty car worth $1600 KBB. This car is of the age, value, and appearance that I am simply going to run it until it won't run anymore or it needs a pricey repair. I am still keeping up on brakes, tires, and I did just replace the struts DIY recently.
