Stp stop leak for old cars
Since my car is older than my dorm RA’s playlist, I grabbed this STP high mileage oil treatment + stop leak for weekend grocery runs from campus. My Civic has like 180k miles and was starting to leave tiny oil spots where I park behind the dorm. I poured the whole bottle in when i changed the oil in the parking lot with my roommate watching TikToks. drove it around for a week and the little spots on the concrete are basically gone and the engine sounds smoother. I’m glad it’s thick enough that the engine doesn’t sound so rattly when I hop on the highway to go home.

Good for my old college car
I grabbed this for my ancient Honda that i keep on campus. It was drinking oil and leaving tiny spots in the dorm lot. I poured the whole bottle in after an oil change and the dripping slowed a ton. Engine sounds smoother now too. Reallly glad my car made it through finals week drives.

Recommended for high mileage cars
I always use this for my Kia Sportage. With normal maintenance, I am pussing 190,000 miles on the car and I haven’t had many issues with adding this when I need an oil change.

Oil leak
Bought this because my car has a very small oil leak in the top somewhere. So far it doesn’t really seem to work too good.
