Great product for high mileage vehicles.
Great value and I use in all my high mileage vehicles and the treatment has preformed as expected.

Happy with new STP rated for synthetic oil.
I use this to add extra lubrication and increase oil viscosity. I buy a nice used car, then drive it till it drops, which is typically about 10 years. My current Suburban I bought with 214,000 miles and now has over 300,000 miles. Before adding the STP, my oil pressure had dropped to about 36 psia at highway speed, so I added some of the new STP rated for synthetic oil and, after a few days of driving, my pressure was up to the perfect 43. I've been using STP standard of conventional oil for decades and it really does protect and extend my engines. I've now moved to synthetic and new STP for synthetic oil with good results.
