Oil Change - Perhaps Royal Purple?
 

Hello Fellow 86 members! I know many of you guys are wanting to do an oil change ASAP. For those of you with Pep Boys around the area, they are providing a $35 discount when you purchase 5QT & an oil filter. This should bring the total oil change cost to roughly $30-$35.

there is a reason there is a coupon for it.
that crap never sees my garage
now, RP synth max atf is good stuff

Any reputable sources or anyone with bad experience? I ran RP for awhile in my RX-8 without a problem (yes we can use synthetic). Then I switched to Mobil 1 and my engine seals gave out at 90k miles. I'm not sure if it's the oil or just the common RX-8 curse.

I've always heard mixed things about RP oil. I personally plan on going with the Subaru oil for my FR-S. I assume other popular oils aren't tailored for boxer engines, and in that case, Subaru oil should be the best.

I have an old streetported N/A FC and have only used Idemitsu oil in it (premix and engine oil). Idemitsu Rotary Engine oil is just that. Oil tailored to rotary engines ;p. Additionally, rotary engines typically need a rebuild much sooner than piston engines, so it's not surprising your seals gave out at 90k.

At the end of the day, I doubt it matters which oil you plan on using if all one does is street driving.

RP 5W-20 is the go to oil for the SVT Focus crowd, that is all my Focus has seen in 60K miles. costs a bit more, but I don't worry about running an extra 1000 miles (usually 4k) before the next oil change. Most swear by it, and it was in my car when I got it, so it stayed.

both oils I avoid...

That's a great deal, thanks.

Nothing wrong with Royal Purple. They make great synthetic oils and a really supportive company for racers.

Royal Purple is fine and the reformulated GF5 oil is made from Group IV and Group V base stocks (according to emails from RP). If anyone has data showing that RP 0W-20 (or Mobil1) is not good a good choice in a BRZ/FRS, then I'm all ears.

An inadequate oil, be it because of its grade or poor quality, would do damage in the long run. Heck you could run with olive oil for a few miles before the engine gives out...

It's a bit like saying you were just fine when running naked in the snow and caught that darn cold right when you sat by the fire. Not that I do that often. :D

You'll be fine using RP.

For the Supra's $$$ V160 tranny, owners swear by RP Synchromax over the Castrol oem oil. I'm running RP Sychromax and MaxGear in my Soup w/out any issues. I run the Shell Rotella T6 in my motor.

royal purple has been confirmed to be...not the best in a subaru motor. i don't know of ANY subaru owners running it and if they did, they immediately switched. i would never touch anything royal purple.

they may be good. but not for a boxer motor.

rotella t6 has excellent results. this is my UOA on my sti with rotella.

The Subaru WRX owner's that have run it, and had it analyzed, were running the Energy Conserving 5W-30 or 10W-30 in a turbo. RP even recommends on their web site to use their HPS oil in a modified car.

Go post your STI analysis at IWSTI.com :). Compare apples to apples please. Oh wait, you did post this over there.

Motul FTW lol

ive used rp for years without any issue (3s-ge engine)

Anyone have any thoughts on AMSOIL? Was planning to go with that as it worked wonderfully well in my S2K...

I used RP in my b16, and rb26 with no ill effects afaik. I didn't get my oil analyzed, and changed it excessively frequently though... Most of the oilguys say it's not so hot, but it was reasonably priced, and it easily available in the weights i wanted to run.

edit: that being said, i'll probably be using the oem oil for now until napa has another 3.49/qt sale :P

dude, relax. it's for reference. i'm not sure what RP everyone was running, i just know it wasn't good. most of these owners have never owned a subaru before, so us that have STi's sure as shit will be able to help and guide them along.

Love Amsoil. Ran it for years in many different vehicles. I really don't think you can go wrong with any of the synthetic oils on the market as long as you change filters and keep up regular oil changes.

I'm just trying to stop the myth that all Royal Purple is bad, or that all Mobil1 is bad.

-Dennis
p.s. - Your fuel dilution is killing the viscosity and Flashpoint of the RT6. It sheared to a 30 weight.

I'm running RP in my BRZ right now, and the engine just BLEW UP!!!!

Oh wait, no it didn't, my bad.

RP is fine, all modern oils that meet the manufacturer specs are fine, some better than others, but none are bad.

I may go amsoil with my future changes just cause I can get it a bit cheaper than the RP I bought, but I wouldn't be against Mobil1, Penzoil, or any of the others.

If you are racing, then that makes a bigger difference.

it's not all bad. i found some old threads with people running RP. if they still are, i'm not sure. i like amsoil also.

Offtopic...did you own a celica before?

:word:

T6 seems to be the fav among the turbo owners. On SF, that's the brand of choice.

Doesn't this forum have rules against trolling? This thread is a really poorly disguised effort. Yet, it is still being fed.

FAIL.

everythingcelica.com :thumbsup:
celica to a wrx to an sti...then after that, i had about 6 other sti's. two at once a few times lol. i have landed one that has been in my hands the past 3 years and probably won't go anywhere.

i like it. we will be doing an UOA on valvoline's vr1 oil too. that has gotten really good reviews also.

I definitely remember your blitz kitted celica. I thought your name sounded familiar. Nice to see we're on the same team yet again;)

gosh i know remember that? blitz front bumper was the fad. then i went full veilside.
i feel like such a ricer:bonk:

it is great! did you use the same username on there? it seems familiar..but i could be mixing it up with someone on iwsti.com

I used Royal Purple for my Evo before. Didn't seem to have any problems. That being said, I'm going to try out ENEOS now. I used it once before for my xB and liked it, but it was impossible to find at the time. I just found out a couple days ago NAPA Auto Parts just became an authorized dealer for ENEOS. I just picked up a case from my local store like 20 minutes ago. Pretty sweet to know I can get it easily now.

I've been running RP 0w20 for the past 500 miles now. Guess what? I lost the crickets. Go figure. It's either the oil or the fact that LA is now running the winter reserve gas. Which has less oxygen in it, AFIK. Something to do with summer gas being less polluting with more oxygen in the gas.

It's my first time I've ever run RP in anything I've owned, but so far it's doing one helluva job. I've pretty much decided to try all sorts of different oils in my car just for the heck of it. Maybe if I'm not too lazy I'll send the stuff off to Blackrock and see what they say. IMHO, I think the oil companies have got us all under their jedi mind trick. If the oil meets the specs then it should do the job. Just because you got better oil, will it protect more for the same abuse??? Only time will tell I guess.

I might pick up some more RP with that Pepboy coupon, then again I might not. But I've deicded to to run Mobil 1 soon after.

I've put Mobil 1 exclusively in both my Honda Ridgeline, and Toyota Camry, without a problem. My trucks at 160k, and still runs like the day I got it.. The Camry doesn't run as good, with 120k but its not running bad by any stretch...

I'm pretty confident I'll get 300k out of the Honda.

I'v run RP 5W-20 in my RX8 for 8 years with no issues what so ever and I have gotten better mileage than most 8 owners ~17 city/24 hwy. I've been to their manufacturing facility here in Houston and I was very impressed with what I saw. Their lead engineer use to race RX3's back in the day and is very familiar with Rotaries and racing in general. I intend to run RP in my FR-S and my CX-5 once its time to change the oil.

I have nothing against Redline or Amsoil, both are also fine products. I support RP cuz they are local and their racing heritage but you can't go wrong with either of the three.

I've got a 2001 Saturn SC1 that I got with 50K miles on it, it now has 280K miles on it and I've been running Wal-Mart full synthetic oil (Super Tech) since I got it and I have had zero problems. It meets current SN and ISLAC GF-5 requirements and SM, SN and ISLAC GF-4 as well.

I'm sure you can have labs analyze your oil and all that, but if the oil you use meets the manufacturers required specs. I certainly wouldn't worry myself to death about it or spend $10 bucks a quart (or more) for something else and that's just my opinion, nothing more.

what exactly is the subaru oil and where can I purchase it?

Saying RP is an inadequate oil is taking it a bit far dont you think? Magazines have ran tests that have showed it scratching the least amount compared to other oils on a bearing test.

To say its not a good oil when their are far worse out there. You can say that about a lot of oils. RP will be fine for your car just dont expect too much out of it. Its just oil. In its class its fine but nothing compared to for example Motul.

Royal Purple ..
I race the LS2 6 litre on it.. after 2 years and many race kilometers I only rebuilt the heads .. all else was fine ... my new 86 race car will only ever run on it.. period

The Subaru OEM oil (which I believe Idemitsu makes). I'm sure you can purchase it from the Subaru dealerships.

thanks! looks like I'm better off just getting the oil and filter from the dealer. does anyone recommend getting the tranny and dif fluid from them also? or should I try another brand? i have a MT

:popcorn:

I just did this yesterday. about $72 for a filter, gasket, and 6 qts of Subaru Synthetic 0W-20 oil.
