When lubricant maker Royal Purple® announced it was going to commemorate the company's 30th anniversary at the 50th Anniversary SEMA show in Las Vegas, November 1-4, 2016, with a Resto-Mod '69 Camaro restyled by Ringbrothers, it was obvious that the company was interested in high-performance cars. But for many old-car buffs, an even more exciting announcement by Royal Purple was the introduction of its new HPS oil.
The so-called "G-Code" Camaro, built by Ringbrothers, symbolized what a modern day performance car looks like and needs. The Camaro (as well as 50 other SEMA sjow cars) utilized Royal Purple products. Under the hood of the G-Code is a modern, high-tech General Motors LS3 V-8 built by Wegner Motorports. This engine features a Whipple supercharger. Inside the motor is Royal Purple 5W30 motor oil, which is well-suited for a modern LS3 engine.
RingBrothers of Spring Green, Wis., created the G-Code '69 Camaro.
But Royal Purple now has a new product that is better suited for older high-performance engines with flat tappet camshaft systems. The new line of HPS motor oils is aimed at the street/performance enthusiast who restores the great, high-compression-engined muscle cars of the 1960s and early 1970s.
It's common knowledge in the old-car and muscle car segments of the hobby that modern lubricants are no longer a good option for cars with high-compression engines. Several years ago, the American Petroleum Institute (API) began reducing maximum limits of common zinc/phosphorus anti-wear additives in motor oils. This reduction was part of API's self-governed licensing program. But the reduction of zinc levels, particularly, were a threat to old-car engines.
The changes forced many enthusiasts to look for alternatives to the API-approved oils that were fine for modern cars, but scary to use in older cars and muscle cars with flat tappet cams in high-compression V-8s. Car owners who worried about wiping out bearings in their motors began using special racing oils that were hard to find and very pricey. Some of these made-for-competition-use lubricants were more than twice as expensive as conventional oils.
To address these problems, Royal Purple decided to bring its new High Performance Street (HPS) motor oil to market. The company carefully points out that these lubricants are designed for "consumers with performance/modified engines and vehicles that have exceeded the factory warranty period."
HPS 5W-30 is a good option for many high-performance cars.
HPS is formulated with Royal Purple's proprietary Synerlec® additive technology and utilizes a more robust zinc/phosphorous anti-wear package than API certification currently allows. Synerlec provides increased oil film strength and the load carrying capability needed by flat tappet and/or high lift camshafts. This additive also exhibits outstanding oxidation resistance compared to common mineral or synthetic API-licensed engine oils. Royal Purple's HPS provides a more affordable option for performance enthusiasts looking for added protection.
The new High-Performance Street oils come in five different blends.
"Oil specifications are now more focused on emissions equipment compatibility at the expense of valve train protection," said Jared Martin, Royal Purple's director of consumer product sales. "As a performance oil manufacturer, we felt the need to tailor an oil line to the needs of our performance-minded customers."
According to Martin, customers can have the best of both worlds. They can select an API licensed motor oil for their car(s) under warranty that require an emission compliant API oil. But, those wanting more performance and wear protection can use HPS in modified vehicles and cars no longer under warranty.
