The Purple
Best oil out there! Want better gas mileage and higher performance? Use Royal Purple and see for yourself. I use the 5w20 in a 2005 Dodge Ram 1500 with the 5.7 HEMI. It cost more because your getting more in every quart. Try it and like me you won't use any thing else in your car or truck. See Facts that I researched before I started using Royal Purple. Do the research or try it for youself before you lend judgements on items or comments by those who have. Of course, buyer always beware. Research: The racing markets associate outstanding quality and superior performance with Royal Purple®. This reputation has been earned through Royal Purple's® relentless pursuit of lubrication excellence. Royal Purple® formulates the most advanced lubricants available on the market today. Synthetic oils enable Royal Purple® to make superior lubricants; however, it is Royal Purple's noncorrosive, proprietary Synerlec® additive technology that provides Royal Purple® lubricants with their amazing performance advantages. Synerlec® additive technology truly is beyond synthetic. Royal Purple's® Synerlec® additive technology forms a tough, ionic, chemical film on all lubricated parts greatly enhancing the oil's performance.

Superior engineering
I have a 1998 ford taurus with 156,000 miles on it. I have been running RP since my mother gave me the car at 120,000 miles. Since then, this car has been resurrected from death. It may be due to the synthetic oils in general, but there is still something to be said about RP specifically. Royal Purple has a high film strength. That property is the single reason for its lubricating superiority -- which results in more horsepower, less friction, less emissions, greater efficiency, and greater fuel economy. I've been using the k&n air filter, RP synthetic, and the RP oil filter. On the drive from Columbus to Philadelphia, the total number of miles traversed over the number of gallons used was equivalent to 30 miles per gallon. This car, stock, was designed to get an EPA estimated 27 miles per gallon. This improvement is no doubt due to a combination of factors including aftermarket iridium bosch spark plugs, royal purple synthetic oil & filter, and the k&n air filter. If you look up the falex lubricity test of this oil compared to the other major synthetic brands, you find that RP is demonstrated to outperform.. However, it's not clear that the all of the independent variables in the experiment were controlled. Specifically heat may not have been controlled, and as the third trial was conducted on RP, there is the possibility that the data was manipulated to give RP an advantage.. If that doesn't make sense without a visual, just search royal purple on youtube and you'll find a few experiments done by royal purple and its competitors on oil film strength.. Think about it, and you'll see what I mean. All I'm saying is RP needs to make more of an effort to demonstrate proper use of the scientific method with their extraordinary claims. After all, extraordinary claims require extraordinary inscrutable evidence. This product came in an amazon box, with the royal purple box of twelve one quart oil bottles within that. Very satisfied for what I ordered. ... show more

Royal Purple....Amazing
I used to use Pennzoil Ultra Advance Synthetic Motor oil and Mobil 1. I switch on and off between them. Both of the oils Work Perfectly fine. Car runs great and then I started to hear about royal purple, How people tell its an amazing oil and works wonders. I thought Synthetic oil is as good as it gets. Until I tried royal purple...this is THE best oil i've tried yet so far, I haven't tried Ams oil nor Red Line. But I'm sticking to Royal Purple, Great Idles, More Torque and Power to the wheels, Engine Overall Performs Excellent. An Oil that Out Performs, Royal Purple. Go Buy it! ... show more

Pricey but good
This is very good quality oil, don't get me wrong. But for this price point, any other API certified synthetic like M1 or Valvoline (etc) is just as good and is easier to get at your local parts store or wallyworld. I think I'll go with RP's HPS formula if I decide to go with a higher performance oil that I can't get locally. ... show more

Noticable improvement in performance and convenience
I'm no car expert. In fact my first car blew up because I didn't know I was supposed to feed it oil at all, but that turned out to be great incentive to learn more about oils! Now, having tried various oils over the past 10 years, I only use Royal Purple whenever possible for a number of reasons: - My car immediately ran smoother and quieter when I switched to Royal Purple - Conveniently, I only have to change my oil every 8,000 to 10,000 miles - Though it costs more per quart, I save money in the long-run due to much less frequent oil changes - Synthetic oils don't seem to gunk up my car's inards nearly as much as organics I also only use Royal Purple in my transmission and differentials. The ironic part of all this is that I work in the oil industry, and most of the people I work with and talk to say to use synthetics. I've shopped around quite a bit, and it seems the prices don't vary much, unless you purchase by the case (12). Amazon is your best bet for that. ... show more

the best motor oil
I purchased a 1989 ford ranger pickup after my xmission went out on my Mercedes ml320. I needed something quickly I was in Tenn. it was Sat morning and I had to be in Maryland Sunday night. The truck looked like new and had a v6 . the oil was clean however I could tell it was changed recently. When I got to Maryland the engine sounded like it was going to come apart.I found out that this v6 had an oiling problem to the rocker arm assembly which was an oversight by engineering when the engine was developed. I got on the Internet and found this oil and read some amazing reviews, so I thought I would give it a try. I have been using it about 2.5 years and without a doubt I am sold on it. The engine was much quieter and ran better. I currently use it in 3 vehicles and will add another soon. Royal Purple motor oil. ... show more

I Dig This Product
While I understand that there are a ton of folks on both sides of the argument on whether this oil is worth the money or not, I am one of those that will say that I am satisfied with this product. Like many people out there, I am not a chemist or oil engineer, but I have done plenty of research and feel as educated as I can get. I feel comfortable using this product. And I feel even better about investing in it since I found it cheaper by the case right here on Amazon. At the discounted price and free shipping (plus discounted oil filter), a quart of RP oil breaks down to about $7.40. That makes it a bit easier on the wallet. Too many ignorants and wannabe "oil experts" are on the internet bashing this product. I'd say research it yourself and make your own decision to either use this product or not. I've done mine, and I have no complaints thus far. ... show more

Best Synthetic Oil
I highly recommend Royal Purple to any one that loves high quality products and is willing to pay the premium. This is my second purchase of the 12qt pack and it has worked very well in my Subaru car. I do recommend a high quality oil filter like the K&N if performance is your desire, but I have used it with OEM filters and nothing bad to write about. The higher gas mileage that some report by using this product is slightly accurate, it just isn't a huge increase considering price. The oil last a long time, in fact, longer than the oil filters but like I said this is the best Synthetic out there so if you can pay for it great, if not, use the cheapest option in my opinion. ... show more
