Purple Oil XPR

[SKY888]

Royal Purple XPR — eXtreme Performance Racing oils are formulated for applications such as racing, modified engines and off-road use. XPR’s high film strength make it exceptionally well-suited for today’s high performance cars and trucks, particularly turbo and supercharged engines and / or engines using a nitrous boost.
XPR produces winning results on the race track and is safe enough to use in your daily commuter car.
Professional engine builders and race teams cite increased horsepower and torque, and longer engine life with the use of Royal Purple and independent tests performed on racing engines show as much as an 80% reduction in wear





After a week of grabbing my car from the dealership, I was able to rack about 200 miles and did my first oil change using Purple Oil XPR. I reset the DIC after the oil change.

3600 miles later, when I checked the DIC, the oil life is only 72%.

I'm not sure if the DIC is a good basis for changing the oil. Regarding oil life, DIC base it on the way you drive, mileage, and etc. I already did about 3400 miles with my Purple Oil XPR, and drove it hard most of the time.

With my previous cars, I usually just changed the oil every 3000 miles and use fully synthetic Mobil 1 5w-30.

Here are my questions:

1.) Do I need to wait until the oil life goes down to 10%?
2.) Should I just do my usual routine and just change the oil every 3000 miles?
3.) Is XPR really that good, and that's why my DIC is telling me that oil life is still 70%, even though I drive my car hard and already went past 3400 miles?


Tech guys.......your input will be appreciated!

Here are my questions:

1.) Do I need to wait until the oil life goes down to 10%?Actually no, keep in mind that the DIC is only a guide, in general, the manual states on my page 250, "Your vehicle has the Engine Oil Life System, a computer system that lets you know when to change the engine oil & filter. This is based on engine revolutions AND engine temperature, AND not on mileage. Based on driving conditions, the mileage at which an oil change will be indicated can vary considerably".
Also use your senses and common sense, I pull the dipstick out and look at the oil, if its still nice and clear, keep going, if its starting to turn black change it. To me the DIC is strictly a guide, I usually change my oil every 6000-7000 miles no matter what the DIC says, and I use M1 15k mile version..
2.) Should I just do my usual routine and just change the oil every 3000 miles?I'll share this site with you also, about the 3000 mile oil myth, you have been trained well.. Motor Oil Myths and Facts
3.) Is XPR really that good, and that's why my DIC is telling me that oil life is still 70%, even though I drive my car hard and already went past 3400 miles? Interesting, this oil is not even on the bible list, or it is under a different nomeclature as far as type on the bible, or perhaps is not a public oil that I can go and buy myself.

In the interest of discloser, I will admit that this source, the "motor oil bible" is created and being maintained by an Amsoil distributor and website. HOWEVER, the data represented is accurate and others in the industry use it as a bible on motor oil and it has yet to be refuted OR the facts false to my knowledge. Below I have attached the bible file for those interested, it is the latest one available, it DOES get updated from time to time as the that particular oil gets changed in any way, those oils with changes are in orange color on the charts on appendix A. Unfortunately due to this site file size limitations of 1.91kb d/l, I could not attach it, BUT the link to the file is attached, go and get it, altho this person is also a religious person, so just ignore all that and just read the oil info, then you will know everything there is to know about oil and oils in general. A couple of site are below. Go here and D/L the bible file, this site won't let me attach anything, file is to big..

1). No. You can change the oil anytime you want, but you really don't want to go past the OIL or one year.
2). Do whatever makes you happy. There are a lot who are rigid in the 3/3000 routine and there's nothing that will convice them otherwise.
3). The DIC has no idea what type of oil you have in the pan. It doesn't perform an analysis, just a calculation from engine temp, rpm, and time running. It's an very good tool, but you can still change earlier if it makes you feel better.

Well I for one have NEVER done the 3000 mile thing. IMHO its just not necessary. This believe has been drilled into everyone's mind so they can get you in for service more often and of course make more money. If you look at almost any car manufacturer's guide, it will state anywhere from 5,000 to 7,500. I usually change mine around 5k but if I'm late a little I don't sweat it. This is especially true with synthetic motor oil. If your changing synthetic at 3k then your crazy. What a waste of money. If this motor oil is even better than the typical synthetic motor oil then I would guestimate that DIC is reading about right but I'm not sure how it calculates oil life. But if this stuff is better then I would say it probably is good for 8 or 9k worth of miles. Do you want to push it that far, I don't know maybe 7 to 8k. Check it as you go past 5k, 6k and so on and see how it looks.

Everyone I'm sure has an opinion on this and that's just mine.

Hi Bro...I'm not sure if the DIC knows if the oil is better or not by analyzing/calculating engine temp/rpm/mileage/etc....but by the looks of it......dic seems to distinguish it. Not sure though.....

Anyways, if I run the oil for about 5-8k, I bet the oil will be good by 8k.......but what I'm worried about is the oil filter. Oil filter might not be good past after 3k? Please englighten me..

thanks!

Sorry but ah, I turned into an oil and filter geek when I bought my roadster..Everything I have posted and referenced I have read every page of those sites.. Of course our filters are not a cartridge, it is only an element, but at least you get an idea on what material is used with these manufacturers and how small the particles that are filtered are.. give ya an idea if you will..
