Rated 5 out of 5 by from Remarkable product!!! STP High Mileage Oil Treatment works wonders. Takes about a week or two for it to fully kick in. Stopped the issues I was having. I highly reccomend it.

Rated 4 out of 5 by from Seems to slow oil leaks Don't know if this works simply because it's thick goop, but adding it did seem to slow down overall oil leakage in an old Rav 4 with over 200K miles. It won't change your life or anything like that.

Rated 5 out of 5 by from Great product feature I brought this for my car that has over 193,000 miles on it. It was running a bit rough and the next oil change is not due for a couple more thousand miles. I added this treatment in the engine and its been running pretty smooth. Today in Southern Ca was over 108 degrees and it had no problems.
