royal purple or mobil 1

[b1epgh24]

Soon i will be changing my oil to synth i was going to put in some mobil 1 but i heard good things on the royal purple so now i dont really know which one i should use is their really a difference .

[RX9]

neither one, i am using Motul 8100 now.

[chinsterr]

neither one, i am using Mutoal now.

But if he is looking of a budget "synthetic" I would go with the Royal Purple.

[aris]

I use Royal Purple....

[Mazda3X2]

Royal Purple.

[Donutz]

Royal purple. As for why, use the forum search engine. There are many really good discussions about oil here on the forums.

[RX9]

motul 8100 is not that expensive. i am not talking about 300V. well, it maybe little bit more than RP, but it still stand stong after 5000km.

[JordanAndrew]

I have never used Royal Purple before but I've been hearing a lot of good things about it so as soon as I run out of free oil changes(I have about 12 free oil changes left, LOL!) then I will switch to royal Purple. I've used Mobil 1 before and it's really good as well so either one works I suppose.

[mazdas3sporte]

iam using good old free oil change iam getting from mazda!,IMO no point using synthetic for normal cars , not including speed 3, dont kill ur self if ur driving a regular 3 , u wont get jack shit when u sell the car, even if its 10 years down the road,

You do realise that these cars use sym synthtic oil right....

What you wrote has nothing to do with what he is asking:loco

I'm using Royal Purple right now and I feel gained about 50 extra km before hitting half tank. Could very well be a placebo effect but its doing good for me so far. Perhaps Mods should have a poll?

[b1epgh24]

ill probably try the royal purple thanks for the suggestions guys

[Zoom Zoom Boy]

Amsoil for me.

[alhope34]

mobil 1, 50,000kms strong in my modded MS3.

mobil 1 in the Yaris for 90,000kms too. I used to abuse that engine a lot, and it still purrs like it's brand new.

[b1epgh24]

at which km would you guyz recommend me to start using full synth is 5200 km to early should i wait at 8000 or 10000km.

[Mazda3X2]

I switched at 1700 kms.

There isn't the same concern for switching early as there used to be. You probably haven't had an oil change yet going by your kms right? I would do it on your first change then. Which I would do fairly soon.

If you car is a turbo (seeing as this is the Mazdaspeed section I'm guessing it is?) I would recommend a grp IV synthetic oil. If not, any grp III would be a good choice.

Good information here;

[alhope34]

I did a regular Mazda change at 1800kms and changed to synthetic at 8000kms. I wouldn't change to a full synthetic earlier than 8000kms because the engine might not get enough friction to do a proper break-in and you could lose compression as the engine ages by a few 10,000 kms.

[Donutz]

Yep; switched to synthetic at my first (or second) oil change.

[aris]

I switched to synthetic at 22,000km...and i used RP

I switched mine when its 16000km, so my second oil change.

[lightingwhite32008.5]

where can u get royal purple, and also do they have the filter to? like amsoil

This is a highly debated subject. Waiting until the first scheduled change is a good idea and a safe bet.

I tend to follow the train of thought that technology advances in the designing and building of the engines at the factory no longer requires the same break in as in days of yore. Drive it right for the first 1000-2000 kms and you're good to go. That's why I like to get the factory oil out shortly after that initial period to get fresh synthetic in.

Others believe in the traditional break in period which is quite a bit longer and requires certain kinds of warms ups and driving conditions.

To each his own. Either way doing the switch at your first scheduled change at around 8k works out.

Here are a couple exeprt from the Amsoil and Royal Purple sites regarding this.


I heard that new cars require a break in period with petroleum before you switch them to synthetic.
Answer: AMSOIL Synthetic Motor Oil can be used during break-in trouble free. In fact, vehicles such as Dodge Viper and Chevrolet Corvette come factory filled with synthetic oil.

Since most new vehicles come filled with petroleum oil, it only makes good sense to change to AMSOIL at the first scheduled oil change interval. New engine components generate high levels of wear metals and can contain contaminants from assembly. By allowing the engine to operate with the petroleum oil until the first oil/filter change interval, the wear metals and contaminants are removed prior to installing AMSOIL.


Can I put Royal Purple into my brand new car?

Yes. Royal Purple currently offers many viscosity grades of API-licensed motor oils. To allow for proper break-in of the engine, Royal Purple recommends waiting until the manufacturer’s first scheduled oil change or a minimum of 2,000 miles in new gasoline engines. Allow 8,000 to 10,000 miles before using Royal Purple in diesel engines.

well for me one of my friend works at Canadian Tire and got me some and for the filter i'm not sure if they have it.

[MRT_MS3]

im getting my oil change tomorrow at oakville and was wondering if they use synthetic for the speed3.

I am pretty sure that they use the same oil as all mazda which is smi synthetic oil

i spoke to a tech at my dealer and they said they use semi synth too.
as for the ratio of synth and dino oil, i dont know for sure but my guess is 20% synth and 80% dino. I dont know why i came up with those numbers, but just a guess :)

if you're lucky enough to own a garage, try learning how to change your own oil, you'll save a lot.

Have you tried on a speed 3? Its a little different than a regular car.
I believe you have to get it done by a shop/dealer or else your warranty will be voided.

I got a hatch but same cartridge filter style. It's not hard.
You won't void warranty, just have to provide all receipts you purchased Mazda oil filters. I even bought the Mazda oil cartridge socket, because it's an odd ball flute count. That and I'd be afraid to add stress onto that plastic housing.

OP, I'd go with Royal Purple but I personally use Amsoil Racing synthetic.

i have never let the dealer do any service on my car since day one. (Ajax)mazda said they wont void my waranty as long as i keep the receipts and write down the km of when i change my oil and do other things. as long as you own the car and did not lease it, i dont see why you cant change the oil yourself without voiding the waranty. check with your dealer and ask them just to be sure, i know some dealers can be quite nasty about this topic (cough cough ....vw at eglinton west of vic park)

[kingpin748]

Change your own oil. Just keep a log and receipts if possible. They can't void a warranty for that.

I've used both oils. Same difference if you ask me. Just change it ever 5000km.

Something interesting about Royal Purple, got it from Racing Beat's site.




Racing Beat has been recommending the use of synthetic oils in rotary applications for several years. Our research has found that synthetic oils provide superior friction reducing between sliding surfaces, reduced foaming, and lower oil temperatures. We have tested several different synthetic oils and have found that while most offered improved wear and lower oil temperatures, none offered any horsepower gains... except for Royal Purple!

Our in-house testing has yielded up to a 2% performance increase after changing from mineral-based oil to Royal Purple Synthetic Motor Oil. How could this be? Jim Mederer, co-founder and chief engineer at Racing Beat, was truly puzzled. With over 35 years of professional racing experience under his belt, he has seen and tried just about every “new” lubricant that hits the market. All offered better wear and lower oil temperatures but none offered any horsepower improvement. After spending time consulting with the engineers at Royal Purple to better understand the reason for the horsepower gain, it was explained that the secret was the proprietary ingredient “Synerlec”. This Synerlec ingredient provides an ultra-slick film on internal engine components to significantly reduce power-robbing friction. Less friction equals more power!

Other professional engine builders have confirmed that Royal Purple Synthetic Racing Oil delivers measurable horsepower gains. Independent dyno tests show increases up to 5% (on smaller displacement engines) with nothing more than an oil change.

No idea if it's true or not, but it's a pretty good endorsement in my opinion.

Link, make sure you select "Oil System" from the drop down on the left, then select any of the oil grades. (http://www.racingbeat.com/FRmiata.htm)

That is good info you posted

Ive been on purple since the start. 50km in and oil change every 4k. They do sell a burn in symthetic oil now :) wasnt there when I got mine changed. Also not I did get free oil changes from mazda but always brought in rp. mazda uses semi synthetic I think.

[steve220s]

Is anyone worried about their catalytic converters when using RP?
I say this because they are certified SL and not SM.
http://www.torontomazda3.ca/forum/showthread.php?t=27258&page=3&highlight=royal+purple

[condor888000]

From what I remember 04/05 cars called for SL oils I wouldn't be too worried. And odds of Mazda doing an oil analysis for a warranty claim seem fairly low to me.

[Mazda3X2]

I am not worried about it personally.

The difference between the SL and SM isn't really all that much and was brought around because of manufactures having to cover their cats under warranty for longer. So they wanted more protection to save themselves any possible claims.

SL API oil rating 2004
zinc = 0.110%, 1100ppm
phosphorous = 0.100%, 1000ppm

SM API oil rating 2005
zinc = 0.087%, 870ppm
phosphorous = 0.080%, 800ppm

I wrote RP about this and they decided against the new SM classification because they believe strongly in the lubrication properties of these additives and until they are satisfied that lower concentrations will provide the same levels of protection will not switch or "upgrade"

I don't know of any cars running SL that had catalyst problems because of zinc or phosphorus coating the inside of their cats and failing emissions.

My opinion.

I found RP's e-mail regarding this and thought I would post it for your info.


Barry,

RP oils are API serviced, but not with the current API SM rating. That is why the star burst in not on the front, but we do have our API license on the back on the bottle.

API SM oils (the most current API service) have reduced anti-wear additives, which are proving that they can not provide the same level of wear protection that the API SL oils do.

The API SM rated oils are designed to extend the life of the exhaust catalyst. The US government (EPA) deemed that oil additives might be a contributing factor in catalysts not working after 5+ years and require that API SM oils have a reduced level of anti-wear additives by 20- 35%.

Royal Purple API SL oils work extremely well and have not caused any catalytic converter problems being used in both high performance vehicles as well as daily drivers. We've decided not to move "up" to an SM rating until we can guarantee the same outstanding wear protection, performance and the ability to extend the drains of the API SL version we currently make. Royal Purple Motor Oils have not had a single catalyst plug or stop working, even using our XPR racing oils in streetcars with over 150,000 miles.

We are offering a corporate warranty to you if you choose to use our SL oil in a car requiring the use of an SM oil and your dealer refuses your warranty on any oil related failures due to the use of our oils. See attached.

Have a great day and thank you for your email.

More importantly than the brand name, is the viscosity.

Wrong viscosity for even one oil change can have significantly more damaging effects than any difference between brands.

This has also been brought up many, many times to much debate as well.

thanks for the info mazda3X2. I think i will go with RP for my next change.
