So today I changed my oil. I switched to 5w-20 Royal Purple oil and a Royal Purple filter. The filter is purple and the oil is colored purple as well.

The RP oil and filter is good for 12k miles. I plan to change my oil every 7500 miles or 6 months. (every october and april) This way I don't have to change it in the middle of the winter. I drive just under 15k miles a year, so it should work out good.

Royal Purple seems expensive, but for the whole year it's really not bad for a top of the line, premium, fully synthetic oil and filter.

Cost:
1 quart = $7.24 (5 quarts = $36.20)
Filter = $13.75

Total: $49.95 + tax = $53.95

1 year total = $107.90

First impression........ it has significantly quieted our normally noisy engine. I didn't notice at first, but after a drive when I got back home I got out and listened and the engine was noticeably quieter. Felt really smooth while driving too, but that could just be the fresh oil feeling. From all the reviews I've read it's supposed to increase horsepower as well. I'll see what the dyno says on that.

Be sure to let us know if that normal engine noise shows it dirty little face again over the next 1000 miles. Then you will have idea as to whether its the RP or just the new oil making it quieter.

RP is good oil, used it in my 97' 3000GT VR4 for 2 years, no complaints.

Damn, about time a Lancer has used RP! I've always wanted to use that, but it will have to wait. Only got like 2600 miles right now haha.

I'd be interested in hearing about how it sounds in a couple of thousand miles later.....see if it still makes it quieter....

Every time my wife is walking around my car while it is idling....she keeps asking if my car is o.k....it sounds weird!

Oh well...whatcha gunna do LOL

Yeah BABY!! join the RP club brother..

For all the ones who asked how it sounds in 1000 miles.. I switched to RP when i had 1000 miles on my car, then changed with RP again at 3500 and now have 8500 and still sounds as quiete as it did when i first changed it. Performance still holds up and oil is significantly cleaner compared to other oils i've used.

I need to change it again but cant find 5-20 in local shopts.. i currenlty drive on 10-40 which is going to suck in winter. (IMG:style_emoticons/default/sad.gif)

I'm sure this question has been asked to death, but I just want to confirm, is it OK for the engine to go from conventional to synthetic at any time? I have about 65000km (40000mi) on mine and looking at the figures, it would be MUCH cheaper to do 2 RP changes than a conventional change every 2 months (i drive about 2k-3k per month)..

Regards.

Some speculate that you should chagne after 12K miles, but on newer engines its proven you an switch with your firest oil change.

For you, having 40K already - you wont have any problems at all. You're way past the questioning point

RP oil and E3 spark plugs have been the 2 products I have seen pushed the most recently, specifically on things like PowerBlock TV. I'm curious what overall results your going to get having switched over to RP. They will show dyno gains from an engine on PowerBlock TV, but thats just from a couple pulls, more curious about over the lifetime of a car not a week of demoing it etc.

Either way it is still hard to get in Canada and I have only so far found the small bottles and have been waiting for the larger bottles to be available before I put too much effort into it.

Thanks for the recommendation bro. You can get the 5w-20 at pep boys or at www.summitracing.com. Summit has it for 7.95 a quart +shipping.




Ya like simmoes said you should be fine, but I would recommend that even if you switch to RP to still chnage the oil every 7500 miles. It's good for 12k but RP says if your still under warranty to stick with the manufactures maintenance schedule.

-------------------------------------------------------------------------------------------------------------
And for everyone else. I'll post back to this thread in a few 1000 miles and let you know how the engine sound is.

*update* - they now have Royal Purple Break-in oil. Im totally switching my oil to that when i buy my next car as soon as i bring it home (IMG:style_emoticons/default/smile.gif)

As far as pepboys, i dont think there are any pepboys in my area, i live in western massachusetts 50 years behind the rest of the world. Im ordering the 5-20 oil on summitracing right now but i dont see the filter there. i've always used k&N filter and it does just fine, but really would like to try the RP filter. (IMG:style_emoticons/default/sad.gif) (((

Pretty important question..

Will doing my own oil change void the warranty? I heard it does for most cars... I mean unless I can give them the oil, but that's still "non OEM" according to them

NO. changing your own oil will not void your warranty, as long as you stick to recomended weight and change it regularly. As long as you have clean oil in your car and you dont overfill or underfill it, you'll be fine.

and keep records...keep the receipts for as long as u own the car

as long as u can prove u did the service they cant deny warranty

Ya I've seen the break in oil, very sweet. I'm also going to try the Purple Ice radiator coolant additive too. Supposed to lower the temp of the engine.

The RP filter is only available at pep-boys, RP has some deal with them. The RP filter is made by champion labs who also makes the K&N filter, so I assume they are very similar if not the same product.

What exactly is the break in oil for? I was reading about it on their site, but it doesn't really make sense to me what the main purpose is. Is it for low mileage cars?

ok guys its time to level on here..... ive never heard of this royal purple stuff.... whats the deal with it? what makes it different from reg oil and is it really worth switching over? pros/cons

Supposed to increase HP, fuel millage, reduce overall engine noise, last longer, increase component life. Everything a good oil should be doing but it has been showing better results than a lot of higher end oils. The gains maybe small but they are showing up on dyno's etc. Gains are small but are due to reduction in friction, MPG gains are the hardest to prove (and minimal anyways) in comparison to it's other claims since you driving habbits, air temp etc all effect your mpg also they are not exactly reliable.

To add what Izerous said (which is right on), it's a full synthetic oil and it also has a proprietary additive that only RP uses called Synerlec.

Here's some info on it:
Synerlec, Royal Purple’s proprietary, additive lubricant technology, is the cornerstone of RP's entire product line. It creates an ionic bond that adheres to metal parts to provide continuous protection even at start-up and strengthens the oil to provide unparalleled performance and protection.

Royal Purple’s high film strength prevents contact between metal parts and improves sealing inside the engine for more complete combustion and dramatically reduced wear. Improved combustion creates more power, better fuel economy and reduced emissions.

Royal Purple remains on the metal surface long after ordinary lubricants would have been squeezed out by pressure and heat. It actually improves engine surfaces by responding to increased pressure with increased viscosity until the metal peaks (asperities) undergo deformation and flow into the low spots. Over time, the metal surface becomes extremely smooth and can even develop a mirror-like surface.


If you do some google searches on RP oil, you'll find lots of racers and engine builders who swear by it. (of course you'll find some critics as well, but most of them are pro-amsoil websites, since RP is amsoil's biggest threat, it makes sense). Just remember RP is API certified and amsoil is not (except for their xl line). Our cars and warranty call for API certified oil only.

aside all the "ionic bonding technology" (IMG:style_emoticons/default/tongue.gif) RP is proven over and over at race tracks. I cant say much about fuel economy, ever since i got my muffler and intake i cant get my foot off the pedal so screw fuel economy. What i do know, is that this is the only oil that holds its viscosity after 5000m of beating. Mobil 1, Penzoil, etc etc come out of the crankcase like water after 5K miles, where as RP comes out as think as it went it. What does that tell you? RP does not lose its chemical properties after many miles of high heat beating (with my driving conditions).

All i need to do now is get Royal Purple tattoo on my a$$ and start getting paid for advertising.. i feel like a whore doing this for free lol

ROFLMAO!
