This oil has been used in my new engine the past 2 years. I started with the Driven BR 15W-50 and once the engine had a 1000 miles on it ,I went to the HR-1 15W-50. It has been a great product and the service at PI has been superb. Thanks to management and staff. Wayne

Product arrived in a well packaged box, with crush proof plastic on the inside top and the oil was packaged in 2's in clear plastic bags. A job well done. I have used the driven break in oil and found it super. I have now installed the 15W50 HR1 street engine oil and have full faith in it's capability to lubricate and protect my engine. Thanks again.

They carry all your performance components you may require at a good price. Shipping time is fast and convenient. Had a issue with a order and their customer service has been amazing with helping deal with the issues and attempt to solve as best as they can. Highly recommended!

Time will tell I guess. seems like the right product for an older muscle car engine

Good oil. No additives needed
