HPS® High Performance Street Motor Oil

I have been using RP street motor oil for many years in multiple vehicles. They run quieter, smooth power, no oil smoke in the exhaust closing in on 200,000 miles. The RP Max 2 cycle oil is also great in chainsaws.

I am very pleased with the follow item I used the royal purple break in oil and I want to follow up with the oil.

Been using this oil for years in many of my motors and it is awesome oil.

Bought this oil to keep a 98′ Accord on the road for many more miles. Has 145000 on now. I will probably go 12000 miles on this oil change. Royal Purple says you can go 15000 miles between changes on this oil. Make sure to get a synthetic filter that is made for extended oil change intervals. Also, a lot of cars will burn some oil going longer between oil changes. So keep an eye on your oil level. I also use this oil in vehicles that see use on my property without seeing any real miles between oil changes. You can change the oil once a year with this oil without worrying about moisture or acidity from fuel blowby that gets in oil on vehicles that are not used all the time. Great product!

I’ve used Royal Purple oil in my modified Mustang GT and both of my Harley’s. It’s a great performance oil and does a great job. The price is reasonable and delivery was as promised.

Customers highly praise the product for its superior performance. Specifically, it’s hailed as the best oil for vejhicles like the ’72 Duster and 602 crate round track car due to its high ZDDP content and dependable performance. Its quality is proven by the time slips users have. Users of synthetic oil also recommend it due to its excellent compatibility. The product exhibits a blend of optimal quality, practiciality, and reliable feautres, making it a top choice for different vehicle types, including street bikes. It clearly outshines the competition.

I have used Royal Purple oil since 2009. I has improved performance, fuel economy etc., and reduced engine wear. I have 165,000 miles and engine runs better than new and has required no engine work other than change the oil an filter with RP products. Improved quick start with royal purple oil filter backflow preventer.

First time motorcycle owner, been riding for about one year. I came across Royal Purple through a friend told me about it. Soon after I researched and did my first oil change with RP. Never looked back. Full synthetic absolutely amazing product, I ride a Yamaha vstar 650 which are known to get hot. RP keeps it alot cooler, last long I try and change it every 3k, sometimes I go 4k still goes strong. Most conventional oils have a burned smell, you can feel the drag on your bike, not RP. Highly recommend the filter gives out way before the oil does. Im amazed at how well it performs. Every change has been with Royal Purple and until they discontinue making it I will keep buying it.

The best oil money can buy.

Got over a million miles out of a 93’Peterbilt with an N14 Cummins using Royal Purple motor oil. Never any guesswork about when to change it, because I always sent the oil samples to a lab for analysis. When the lab test came back positive, I just changed the oil filter and kept on truckin’. This semi truck engine costs more than the price of most new cars. Have always trusted Royal Purple in all of my car engines as well. This oil has never let me down. Using Royal Purple has always saved me money because oil changes could be extended without worry. Use the best oil there is in the best that you have.
