    Rated 5 out of 5 by from Royal Purple HPS street motor oil Excellent synthetic oil. No leaks on Buick 430 motor. More power, less friction and higher oil pressure.

    Rated 5 out of 5 by from A small budget means using the best stuff. I use this oil in my 1977 Buick Electra that I purchased as a daily runner in 1993, This car only goes to shows and cruise nights now days, and I want a full synthetic with the ZDDP additives for peace of mind, as an engine replacement for this car is way out of my budget. This oil is probably overkill for my application, but I only change it once a year, The ratings for this oil are hard to beat, If it’s good enough for the Ring Brothers, that’s all the information I need!

    Rated 5 out of 5 by from RP HPS There is a ton of opinions on oil and some people believe RP is junk oil. I cannot speak for their API oil as I have only used the HPS and XPR oils. I have done more than 10 oil analysis from BlackStone Labs and the tests show positive results. I have used RP oil and lubricants for 7 years now without a oil or lubricant related issue. Mobile 1 Advanced Full synthetic and Pennzoil Ultra are a few that I would use as well. I used Mobile 1 for many years and it's a great oil. Pennzoil Ultra I have wanted to try since it is converted from natural gas called pureplus.

    Rated 5 out of 5 by from Awesome Stuff Once a year oil change, and it still looked clean. Must use the RP oil filter for optimal filtration and performance.

    Rated 5 out of 5 by from Best street motor oil I've used RP HPS oil for several years now. This oil keeps engines quiet and clean. Really stays with it, without burn off or oil loss.
