I have a 2011 Nissan Altima 2.5 SL with about 35k. I was wondering if anyone has ever used Royal Purple Oil Synthetic in this engine? I am mostly looking to extend the life of my engine and quiet down the cold starts. Is it a waste of money and how well does this oil work in this engine? Thanks for reading everyone!!

Never used the Royal purple brand. I believe its a great oil. I do use
the Mobil 1 brand full synthetic and have had great results. what ever
you do choose us the correct weight and viscosity. 5w-30 should be correct.Royal Purle is awesome oil and i use it personally in my car, the 3800 seems too like it a little better, Royal purple has additives like friction modifiers that help the oil cling too parts and lubricate them, it also has excellent film strength… its a good performance motor oil but costs about $9.00 a quart.
but collage mans oil of choice is very good too and is my second choice of oil, Mobile 1 full synthetics are VERY good oils, as well as Valvoline. i greatly dislike Penzoil personally, the biggest thing you can do however is keep your cars oil regularly changed, and use what Vescocity your manufacturer recommends.
also Napa oil is made buy the same company that makes Valvoline.
Royal Purple is among the premium oil brands, and of that group it is probably toward the bottom of the list as quality goes. Mobil 1 ranks a bit lower yet.
However, unless you are using your car for competitive sporting events, about any decent oil will do. My car requires synthetic oil and I go to Walmart and buy whatever is on sale but I change it every 3000 miles. The best oil is clean oil.
I find it rather humorous that certain car brands, who advanced extended oil changes, are now having to do warranty work because owners followed their instruction.

ooh yea, you can go 7,000 miles between oil changes now… thats what they all say, then Royal purple says something like 10,000 miles, sorry im changing my cars oil at the tride and true 3,000 mile rule of thumb, no more than 4,000 miles.
Just reading over what I wrote. Placing Royal Purple at the bottom of the premium brands means it is still a premium brand. But there are better brands and very much more costly. And saying Mobil 1 is a notch below that is another way of saying it is a very good oil.
in your opinion what is the best brand of oil?
too me its all up too the application, oil is oil, what makes most of these oils a “Better.” oil is there additive packages, Royal Purple is more of a performance motor oil and has friction modifiers that reduce friction and enhance oil film, it may also have some detergents. other motor oils have detergents and other additives for higher mileage engines that help seals and gaskets.
you can take oil like Royal Purple and knowing it costs $9.00 a quart, and unless you are out on the track pushing the engine too its limits these oils are almost pointless. for many engines a conventional bottle of Valvaline of the proper vescocity will do the job just fine the biggest thing is changing the oil on a regular bases of 3,000 miles.
I have never used Royal Purple myself but I think it’s overkill for your car. I have used nothing but Castrol lubricants for over 40 years and have never had an oil related part failure in anything I have ever used it in. Castrol Syntech/Edge is one of the few oils that VW Mercedes and BMW endorse for the use in their cars. They have the most stringent oil requirements in the world.
Mobile One would be my second choice.
“in your opinion what is the best brand of oil?”
Well, naming oils for this application is pointless. Now, if you take a 2 liter engine and build it to 600 horsepower using a turbo that boosts to 40 psi and then go out and flog it all afternoon at the track making 9 second runs I would say Brad Penn oil in 20W-50 is the best. However, in the cold that stuff turns into a solid. A guy on another forum had this happen and contacted Brad Penn about it. Their response was, “And the problem is?”
Amsoil also makes a very good product. However, whenever I think about the fact that they also sell a 25,000 mile oil filter smoke comes out of my ears.
Amsoil has a 10W-40 oil they sell for stationary engines that contains no plastic (viscosity indexers) so it is all oil. I’ve tried to get them to sell it with an automotive package but so far no joy.
Like said above a few times, use a quality oil at the right viscosity. I like using Castrol and Shell oil. But that’s really because those jugs are closer to the till where I buy bulk when I need it.
I like the above statement that reads the best oil for your car is clean oil. If you really want to extend the life of your engine change the oil routinely. In recent years I’m lucky to put 15,000km on my car in a year. Witch if you look at the time over km Id be way over due each time. Now I just change it with the turn of each season. IE one at the start of spring, one for summer, one start of fall, one start of winter, etc.
It drains out cleaner than most cars but at least I know its clean. My car is older, reliability is crucial for me.I’ve been an AMSOIL dealer for 15 years, new to this forum. Would like to make a couple of points:
1. The AMSOIL engine oil filters come in two versions, 1yr/15K miles and 1yr/25K miles. The difference is filter size (capacity).
2. There’s no such additive termed “viscosity indexer.” The oil you are referring to is formulated for Natural Gas stationary engines. If you’re looking for an automotive 10W-40 we have two choices – Premium Protection and XL. They’re both excellent.
A synthetic oil will help you out where noisy cold starts are concerned. I don’t always follow the manufacturers advice on oil viscosity, especially where 5W-20 is concerned. For several years I have used 0W-30 in winter and 15W-40 in summer without issue. That said, I don’t think 15W-40 is the best choice for OHC engines unless they’re turbocharged.
Extended service intervals are bunk in my opinion simply because few of us drive under ideal conditions. I have sent several oil samples in and most are near the end of useful life around the 3500 mile mark in fuel injected engines. Blackstone lab results indicated a base number of 3 at that mileage, and the oil I put in has a base number of 12. I could run my oil a bit longer, but I see no way it would ever make the 7500 mile mark…
Every time someone asks a question like this on internet forums there seem to pages of opinions.
None of us designed, built and tested the 2.4 Altima engine, and no one here is an oil scientist or lubrication engineering specialist that has tested numerous oils in that engine.
You cannot soundly argue that one premium synthetic oil of the same grade and spec is better than another premium product of the same grade and spec in the same vehicle running in the same conditions unless you run a comprehensive independent scientific test.
I could not argue that YY Brand 5w-30 ILSAC GF5 was a better oil than XX brand 5w-30 ILSAC GF5 unless it was scientifically tested in the same engine. It is also possible that one oil will perform better in a particular engine than the same spec oil of another brand but that may not be the case for all other engines tested with the same oils where that same oil spec is recommended by the manufacturer.
You do not know until you run scientific tests. Everything else is marketing hype, opinion and conjecture.
If the original poster wants to use Royal Purple and it makes him feel better that he is using a premium oil in his car – fine – as long as he is using the correct grade and spec as stipulated by Nissan for that 2.4 engine. He will never know if it would be better in that engine than a Castrol or Mobil 1 or Shell or Valvoline etc etc fully synthetic oil of exactly the same grade and spec. Only careful comparative testing would show, including pulling down the engine for wear tests.
The best thing he can do is:
1. Select a fully synthetic oil from a reputable manufacturer of the correct grade and spec for his car.
2. Change the oil and oil filter much more frequently that the manufacturer recommends. As a minimum at least twice the frequency recommended by Nissan because the oil change intervals on time and mileage now recommended by manufacturers are there for range of reasons other than minimizing wear on your engine and only apply under the most ideal of running conditions that few if any owners would ever emulate. (In fact if you read the fine print in owner’s manuals(few do) you will see that many manufacturers recommend more frequent oil changes than their standard service book shows based on the kind of driving many of us do which is far from ideal when considering engine wear and oil contamination etc).
In short select the correct spec fully synthetic oil as recommended by Nissan for your Altima engine and keep it clean by changing it (and the oil filter) frequently. If the manufacturer recommends different grades for colder months in your area of the world then follow that recommendation.
As with BarneyB, I am also a fan of 3000 mile oil change intervals(sometimes less miles than that) even though I use a premium brand synthetic which are claimed to last much longer. The oil change intervals (and using the correct grade and spec oil) are 100 times more important than whether you use Shell, or Valvoline or Castrol or Mobil or Penrite or Royal Purple or other reputable brand.
If Royal Purple have proof that their synthetic oils out perform all other brands of oils of the same grade and spec in all car engines I would like to see the evidence and the details of the testing they did. I doubt however that they make any such claim.
i don’t necessarily agree that royal purples oil change intervals of some what is it over 10,000 miles is a good thing? heck no i think that is a horrible idea! i don’t think any sort of oil will allow massive oil change intervals like that, your oil is going to get dirty and that is just the bottom line, i have said it and i will say it again, the best thing you can do is change your oil on a regular basis, and i have always been the guy who likes the 3,000 mile oil change interval, i could care less what royal purple says, i could care less about what the manufacturer for my car says, 3,000 miles is when i change my oil.
now as for longer engine life once again i doubt that its going too make a super huge difference! in fact a guy i worked with had experiences with this, a friend of his was advertizing for royal purple and was using it in his truck, well his engine wore out in his truck at relatively the same time as it usually would! the best thing you can do too prolong the life of your engine is too change the oil, the filter on a regular bases and that is once again too me every 3,000 miles and use the oil your manufacturer recommends like 5W-30 in the case of my car, and if it recommends synthetic use it!
i like royal purple personally because i think the engine in my car runs on it best, and i have used MANY oils in my vehicles over the years, i used too drive 200 miles every day and oil changes where a monthly thing, i have tried Valvoline and have, i have tried multiple kinds of Mobile 1 from synthetics too just regular oil, i have even had off brand cheep o oil in engines before and too me the oil the engine seems too run the best on in my experiences are Royal purple, Mobile 1, and Valvoline in my cars i have had.
Like you Ace, I am also a fan of Mobil 1.
However – I switched in one of my cars from the Mobil 1 to Valvoline fully synthetic in the same grade and spec as the Mobil 1 recently just to try it out. This car has only run 13000 miles.
Do I notice any difference at all driving the car. NO
Does the engine sound any different? NO
is the engine still running very smoothly at all rpms used on street? YES
Is the engine consuming oil? NO
Is the oil getting dirtier than the Mobil 1 was over the same time and mileage? NO
Do I change the oil(regardless of brand) much more frequently than the manufacturer suggests? YESHow can I possibly sustain an argument that one of these oils is better than the other?
SO FAR I CAN’T (at least not without doing multiple engine dis-assemblies which I sure will not be doing)
