I have included the major brands that I know of. I am limited to 10 choices unfortunately.
Royal Purple uses a different chemistry than most oils. They are one of only a handful of marketers using Molybdenum Disulfide (Moly) in their oil. Moly is a solid material, which is specifically banned by Cummins®, due to excessive valve train wear.And what would those be?
Professional engine builders and race teams have cited increased horsepower and torque, and longer engine life with the use of Royal Purple According to multi-year IHRA Top Fuel Champion Clay Millican, “When we began using Royal Purple, I couldn’t believe the difference. Run any oil back to back with Royal Purple and you’ll see a difference.” It produces winning results on the racetrack and is safe enough to use in your daily commuter car.
This was a post from another forum..........Royal Purple is garbage in daily driven vehicles. I'll never use it in any of mine. The motor I'm running now in my truck was used for 50Kmiles on Royal Purple before I got it. The whole inside of the engine was coated in a thin purple film. Not something I want on the inside of my motor.
Royal Purple is purple so one will find a purple coating.
I guess the guy with the truck is :4-looney:.Does Royal Purple maintain its purple color after it’s put into service?
No. The dye that’s used to color the oil dissipates shortly after being put into service. The color will turn brown at some point.
Maybe......I was just fowarding info. Never truthfully said I stood by the statements, they just steered me away from royal purple. Originally I was going to use it but decided to stay with Mobil 1. I've beem using mobil 1 since I can remember......old habits are hard to break .I guess the guy with the truck is :4-looney:.
Not pinging on you, just the truck guy. It seems that for every person that "swears" by something, there's another person that "swears" at it. That's why facts are more important than opinions. As Patrick Moynihan once said: "You are entitled to your own opinion, but not your own facts."Maybe......I was just fowarding info. Never truthfully said I stood by the statements, they just steered me away from royal purple. Originally I was going to use it but decided to stay with Mobil 1. I've beem using mobil 1 since I can remember......old habits are hard to break .
BTW did you install the replacement filter or the CAI? I used the mopar filter....but didn't drive my car long enough before to get an idea of any increase of performance.
On another note. I read an article written by a motorcycle race crew chief where he described the loss of the oil pump during a race with 5 laps to go. He credited the Royal Purple with it's ability to leave a protective coating on the engine parts for allowing the rider to finish the race...in first place.
If you liked that, how about this one:Very interesting......more info like that could certainly change my mind!!!
Racing Beat has been recommending the use of synthetic oils in rotary applications for several years. Our research has found that synthetic oils provide superior friction reducing between sliding surfaces, reduced foaming, and lower oil temperatures. We have tested several different synthetic oils and have found that while most offered improved wear and lower oil temperatures, none offered any horsepower gains... except for Royal Purple!
Our in-house testing has yielded up to a 2% performance increase after changing from mineral-based oil to Royal Purple Synthetic Motor Oil. How could this be? Jim Mederer, co-founder and chief engineer at Racing Beat, was truly puzzled. With over 35 years of professional racing experience under his belt, he has seen and tried just about every “new” lubricant that hits the market. All offered better wear and lower oil temperatures but none offered any horsepower improvement. After spending time consulting with the engineers at Royal Purple to better understand the reason for the horsepower gain, it was explained that the secret was the proprietary ingredient “Synerlec”. This Synerlec ingredient provides an ultra-slick film on internal engine components to significantly reduce power-robbing friction. Less friction equals more power!
Other professional engine builders have confirmed that Royal Purple Synthetic Racing Oil delivers measurable horsepower gains. Independent dyno tests show increases up to 5% (on smaller displacement engines) with nothing more than an oil change.
