Royal Purple11744 HMX SAE 5W-30 High-Mileage Synthetic Motor Oil - 1 Quart

Listen, I get it. Everyone has some automotive elixir or magic potion they swear by. "Put this in your tank, and it will be like a new car!" We all wish it were true, but in reality, there's nothing you're going to put in an engine to bring it back to life, or keep it running 500,000 miles. But I can tell you this with complete honesty: Royal Purple was (and continues to be) absolutely worth the money in my case.At around 140,000 miles, the engine of my 2008 Jeep Grand Cherokee was noticeably louder than it was in its youth. Not a terrible noise, but there was definitely a mechanical clatter that wasn't there before. I'd also started to notice that when I changed the oil, I was getting less and less back out. I'd put 5 Qts in, and 3,000 miles later I'd drain out just 3 or even 2.5 Qts. I never noticed any oil on the driveway, so I don't know if it was burning it or only leaking while running, but it was going somewhere.One morning, after I'd gotten a little lazy and went a bit past my usual 3K oil change interval, I noticed the oil pressure light starting to flicker. Checked the stick and it was just barely registering. Something had to give. I didn't want to be the guy putting a Qt of oil in his old clunker every week (in other words, my Dad).So I started looking around and saw that Royal Purple was making some big claims with their high-mileage oil. Rejuvenating seals and cleaning your engine, that sort of thing. I kept doing more research, and the surprising thing was that more and more people seemed to be backing it up. What finally convinced me to make the switch was a YouTube video where they took the valve covers off an old engine before and after running Royal Purple through it -- there was no denying it looked cleaner inside.So I spent the money, even got the proper filter. Went ahead and did the shorter interval for the first change that they recommend to get the loose stuff out of the system before really settling in to the fully synthetic oil, even though it meant spending double. I figured if it worked, it was worth the money.Well, that was over 20,000 miles ago, and I'll be damned if things haven't improved. The engine is without question quieter, and at idle, is noticeably smoother running. But the best part is that the oil loss has been reduced dramatically. Now when I put in 5 Qts, I get 4 Qts back out. It's not perfect, but considering nothing has changed other than the oil, I think that's a big win. I no longer have to religiously check the dip stick every week for fear of an empty pan before the kid needs to go to school.End of the day, I'm just one guy who enjoys fiddling under the hood from time to time. I'm no expert, I can't tell you how or why things improved with Royal Purple. Maybe it's all just coincidence? All I know is that it's worth it for me to keep spending the extra money. I want to keep my engine running as well as possible, for as long as possible, and to me that means always using Royal Purple.

We have a Toyota Prius V with 211,000 miles.For it's entire life, I've only ran Royal Purple and the engine shows no signs of wear or mechanical issues.I use Royal Purple filters as well.This is the high mileage formula, designed for smaller engines which run at slightly higher RPM's and the oil also compensates for slightly increased critical surface area tolerances, again, due to the higher mileage.Royal Purple as a 100% synthetic product does cost more than standard organic petroleum products but based on my results, I cannot justify using anything but synthetics.I would highly recommend Royal Purple products for all of your automotive, both commercial and passenger, needs.

My car just rolled past 200,000 miles and I want another 200,000 miles out of her so I did a lot of research for my next oil change and I'm so happy with the performance, appearance, and color of this oil. It is designed for high mileage vehicles and will seal and give great temperature control for the engine. It's called purple, but it's the color of regular oil. It's the right viscosity for my engine and it lasts 75,000 between oil changes. Really incredible!!!

This oil works very well especially in cleaning the internal engine !

I'm driving a vehicle that has 250k miles on it and had probably never had any kind of engine treatment, so of corse the top of the head had allot of carbon build up... I've heard only good things about Royal Purple oil and filter, so I did some more research and found I don't have to add any kinda of engine treatment that could possibly cause damage to seals or gaskets... I wanted a product to basically pour in run for a period of time that's not an additive... I have now had Royal Purple high millage oil and filter in it for about 450 miles.. Im highly impressed with the power gain (whitch isn't much), the idle is cleaner aswell as inside my valvue cover looks clean enough to eat off of. I'm going to run it about anouther 450 miles and change it again with Royal purple oil and filter... 100% recommend

I just changed my oil last week from Castrol 5-30 to this stuff. holy cow my car runs so smooth now. kind of stayed away from RP since its priced so high, but I though about tryin it out since I only needed 5quarts for a oil change and it was only a few $ more at the time. well worth it. would order again, vehicle in question is 2013 Nissan Juke with 95k miles on it

I drained out Castrol High Mileage Synthetic blend from my 07 chevy Suburban with a 5.3 and replaced it with this royal purple high mileage. At start up it sounded about the same...Slightly less noise I would say. I'm not sure if you can say it was quieter because of the Royal Purple or because the Castrol had 2,500 miles on it and it was time for a change. I will say that it did have a little valve noise at first. It did however quiet down after about 2minutes; which I would assume is about how long it took the oil to fully cycle through the motor and coat the metal surfaces well enough.I did notice a difference on long road trips and after I got the motor really warmed up. The Castrol always had a slight valve rattle even when it was just poured in. The Royal Purple seems to keep the noise down at all temps, especially after long trips when the engine is nice and hot. When I pull up to a stop I no longer have the infamous 5.3 afm rattle. If you know about the chevy afm motor you know what I am talking about.My 5.3 has never really had a problem with excessive oil consumption, so I can not speak for oil burn with the Royal Purple. I generally have put .75 to 1 quart per 3k. I would not consider that an oil consumption problem. I have 120k on the motor and it runs Very strong; 1 quart every 3k is fine by me.Overall, I think it has made my engine run a bit smoother and quieter. I will buy again.

Love the color but better than that I have had excellent results with this product.Improves my old cars engine.I drive a 2012 BMW 128i coupe and have 222000 kms on that girl. Changed the Vanos selenoids and still had a rough idle at start. Was going to clean the Vanos oil screens but decided to just use this oil to do so and I have no regrets.

The price: Too much expensive

El aceite es cierto que llega en presentación diferente a la de la foto, pero el producto es genuino y el precio es más accesible que en auto zone mexico

I use royal purple for all my fluids in my 00 civic, best quality, but comes at a price, but if you care about your ride spending a lil extra on maintenance items in my books is worth it. Especially when you can tell the difference of drive quality royal purple oil has compared to castrol high mileage oil.

Excelente llego antes de lo previsto y está funcionando al 100 gracias muy recomendable
