I'm thinking about swapping the mobile 1 for this after watching the video.

Video marketing is done by marketing genius's, is there a problem with the oil you are using right now? I see quite a few 50,000+ mile Vettes still running great and they are using the oil the factory put in it...Mobil 1.

Royal Purple is better....I felt a difference....runs smoother.

I think it was a sales picth!

Nope no problems the I can see or feel. Sample A of the video was supposed to be mobile 1. Was it? Who knows but if it was, it was terrible. Again who knows what was in the silver bottle, but if it was indeed a fair test with the real oils than the royal purple was impressive.

Sorry, but I say absolute...

There are definitely some better oils than Mobil1 from a lubrication and cleaning standpoint, but whether or not they are better for your car is up in the air.

Im running Pennzoil Ultra because I can get it relatively cheap ( only 3$ more per 5Qt jug than Mobil1 - so 6$ per oil change ) and on paper its a better oil.

"I felt a difference"

I notice that you can't reply to that post. Which speaks volumes to me.

It also appears that the only thing they are testing is the film strength. There are a whole lot of other properties of modern oil that are important that they totally ignore.

This happened when purple was first introduced:

A Corvette owner at the local Corvette shop was changing his oil to RP a day or so before we had a drag event. Said he expected with the RP in the crankcase he was going to run at least two tenths quicker in the 1/4! And, he was serious!!!!
Mutton head for certain...he actually ran slower, but someone convinced this guy that RP was a magic solution to better drag times. This at a time when most of us ran Redline in our cars.
You will not feel any difference seat of the pants wise or actual track time wise just by running snake oil....pure myth and marketing gimmick. A long time ago I represented Prolong, I know.

I was not interested in track times or better performance. I was simply posting for wear over time.

i can buy oreillys brand oil put a new label on it, have a video guy make a really slick video and sell it for $20 a quart. good oil is good none is really any better than the rest. its personal prefferance. they make videos like that for that exact reason to get you to buy their product.

I’ll repeat a reply I made to a similar question about the Royal Purple video a few weeks ago. If you saw it then, my apologies for the repeat. Simply ignore it now.

I am wary of tests that are as far away from actual engine application as the one in their video. What the video shows is that under cold start conditions, at loads vastly in excess of anything that will ever be encountered in an engine, and with oil “right out of the can”, Royal Purple beats the other oils. In real life, you have much lower loads, much more variable temperature, and must deal with aging of the oil due to extended time at high temperature and to contamination with carbon sludge. I remember a test by Consumer Reports magazine of several years ago, rating oils based on performance on some sort of bench test rig similar at least in concept to the one in the Royal Purple video. My company had done actual engine tests of several of the oils in the Consumer Reports tests, and they gave dramatically different results. The best two oils in the Consumer Reports tests were among the poorest in actual engine testing, while several of the top rated in engine tests were poor in the Consumer Reports test. That statement absolutely and positively should not be interpreted as meaning Royal Purple is a poor oil. It simply says that it’s dangerous to try to predict real world engine results with small scale, quick, bench tests.

The only true test is an actual engine test under controlled conditions in a dynomometer cell, and those are very expensive and time consuming. I have seen such tests on many conventional oils and a few synthetics. In such tests, the synthetics invariably due better than conventionals, a tiny bit better under “normal” conditions, with the differences increasing as conditions get more severe. Unfortunately, two thing prevent me from making any comments about Royal Purple. First, I don’t want to get in the business of recommending specific brands, and second, I have not seen engine test data on Royal Purple anyway. So bottom line, I don’t have any basis to say anything either good or bad about Royal Purple engine performance, but by the same token, I don’t see that the test in the video is very relevant either. As long as you choose a 5W-30 fully synthetic oil that meets GM4718M spec (I think Royal Purple does, but I'm not totally sure of that) you should be ok.

what do I say about the ad? advertising seems to work on some people....otherwise, it wouldn't be in that form.

I've felt a difference when switching oils but not in power only primarily in cold start ups the engine made a bit less valve noise. I personally have used mobil 1 castrol syntec and RP and out of the three I cannot say for sure if any difference was present. I have a personal preference for castrol but only because of a couple engine tear downs I've done that ran castrol. They were very 'clean' inside; again not saying that mobil 1 or RP isnt as good, I just have visual knowledge castrol works well. I have lost an engine using mobil 1 but it was a tired engine that had large clearances which I believe lead to the oil escaping the bearing surfaces too quickly, so I cant fully blame the oil type. Honestly I don't think there is much difference in the high quality synthetics. Just stick with a good synthetic and you'll probably wear the car out before the oil wears the engine out.

Now that's some shhhh right there!

Advertising does work on some people.....it's the same reason they put Mobil 1 on the oil filler cap.

coolsrt8

I didn't know you could smoke Royal Purple

kencz51

My car runs better after a car wash too. Lol.

And with all due respect to the post below yours, no way do I believe an engine runs smoother with a different oil. There is simply no way that is going to happen unless the oil you had in it before was total garbage.
