i just bought and installed my brand new greddy turbo and it leaked and smoked like crazy. when i sent it back to greddy to get it checked out they told me that royal purple tends to gunk up in the turbo and eventually causes it to leak. So greddy does recommend for turbos, but they dont adtervise it. Just a heads up to people that use the oil.

 

wait so wat do they reccomend? and wat is bad?? i use royal purple and it works greatttt for me. never had a problem and enver heard of a problem b4

 

i have heard of the "royal purple gunk" so to speak

i know a very reputable LS1 builder tuner that had a couple/few motors take a **** for no apparent reason. they all had one thing in common.... royal purple

now i've never used thier motor oil but i used their synthetic trans fluid and i've tried A LOT of different fluids in the tranny and that was by FAR the worst i've used.

i would recommend mobil 1... tried and true to work.. plus i pulled apart a 90K LS motor that had mobil 1 all its life and i have pulled apart a lot of motors and i have never seen something so beautiful after 90K and 7 years. it looked brand spankin new. although i do use Castrol GTX myself which is also a great oil just change it more often than synthetic. i woulda stuck with Mobil 1 but for a while i was burning so much oil it got rediculous to keep using.

 

i spoke with chris at greddy and he recommends mobil 1 because of the high viscosity... he gets alot of bad turbos from customers and its usually from royal purple, so he says.

Explain to me how "mobil 1 has higher viscosity"? Since when does oil brand matter for viscosity? A rating is a rating, 10w-30 is 10w-30 whether its oil, water, ****, beer, dish soap etc.

That's like saying 10lbs of feathers is less weight than 10lbs of lead. *eyeroll*

FYI, I've run Royal Purple for over a year with no issues. And that's on a normally unreliable DSM.

 

royal purple is very good oil.....i don't believe all the info you guys are sharing is correct.

it's my understanding that all turbo manufactures will always blame the brand/type of oil used when it comes to one of their turbo's coming back with a failure. it's just how they like to deal with warranty issues....blaim everything else except the fact their component is a POS.

 

I sell Royal Purple and use it in all my cars, 0 problems here

 

I can tell you I have never installed a greddy kit on a honda but I have done about 12 on 350z's and atleast half the guys were using royal purple with out any problems and I used it on my turboed CRX and the car has been running for a year. You might want to try amsoil, or redline if royal purple is not working out for you.

 

Royal Purple 5w30 made my Garrett 60 trim smoke, but the 10w30 didn't....i have since stopped using it entirely

 

Uhhh, I had never heard anything bad until now! Does anyone have some factual back up to NOT use Royal Purple for turbos??

I have a Greddy turbo, and I just bought 4 quarts of RP to put in my car this weekend, but now I'm a little worried...

Well if you were to read any of the above posts, like mine, you would have some factual back up. Here's what you need to know....i ran Royal Purple for a little while, the turbo began to smoke on hard pulls, i changed to a different kind of oil and no more smoke....that's pretty cut and dry to me

I DID read the post, and you seem to be one of the only people that had a problem with Royal Purple. I'm seeing more posts of people saying it works great, and until this thread, I've only heard good things.

I'm trying to see if there's factual evidence that this oil does in fact gunk up, or if it IS in fact a bad oil to use for Turbos. I understand that's your experience, and if I were in your shoes, I would have done the same thing. HOWEVER, I read about 1 or 2 random bad cases on Honda-Tech all of the damn time when theres hundreds of other good experiences, so I'm trying to look at both sides to make my decision.

I will probably end up going back to Mobil 1, but I have heard a LOT of great things about this oil, so I was looking forward to using it.

^^^^ NO its not factual backup... but here is the way i look at it... have you ever heard anything bad about Mobil 1?

and here is some backup on the Mobil 1 i saw for my self

and the builder that i spoke of that had the LS1 failures said there was a unusual amount of buildup.. which from my understanding is from ash in the oil.. or lack of ash filtering by the oil manufacturer i could be wrong but i believe that is what it is...


BESIDES... putting PURPLE oil in my built motor has always made me a bit uncomfortable

big deal, ive pulled apart motors that got infrequent oil changes on dino oil and they looked perfect. thats not a factual proof that royal purple is no good.

really..


point is bad mouthing a product usually dosent come outta nowhere just like if your buddy says he heard so and so is bangin your girl it stemmed from something didnt come outta mid air. so i usually have reason to suspect that there may be some truth to rumors you just gotta filter out the BS i myself will go with a product i have SEEN work very well.

and lastly i started my statement with "not factual proof" so get off it. it was IMO. and that was made clear

Actually yes I have read bad things about Mobil 1. If you search through the oil forums, you will find all the info. you need about Mobil 1 to make an educated decision. Think of it like this: if you like Hondas then there is a good chance you'll go to HondaTech to learn something (sometimes haha). If you like oil then you go to the oil forums. What I'm trying to say is that I would not rely on HondaTech to give good info. on oil. Just as I wouldn't go to Mustang.com to learn about Honda engines. Go read those and you'll read plenty of factual data and proof that is against Mobil 1. But the jist of it is about M1, is that basically breaks down at a much faster rate and becomes thinner than other oils much faster. That's what I read/saw in data so take it as a grain of salt. Do you own homework and make your own decision about what is "best".

 

Good Debate, just in time for my next purchase - motor oil

What brand 10w30? So maybe the heavier oil worked better not so much the brand?

One thing is it is not recommended to start using Synthetic oil on an OLD MOTOR , I guess maybe over 50k+ miles. Synthetic is also not recommended for break in on a motor so....

ehh that sucks didnt know that one. will put that on the list of things to do lol. i have always used Castrol GTX myself and change it a little more often. it seems to be one of the better conventional oils. again i may read up on that one too

mainly i was very impressed with the condition of the engine i took apart after 8 years and almost 100k miles and 2 different turbo set ups. but i am also more used to every day cars being that i work for a mechanical repair shop. was a tech for years.

was there a thread comparing oils or was it mostly based on M1?

ill search and see what i come up with also

 

im not trying to diss royal purple, but to me it brings concerns that why a brand new greddy turbo go bad and smoke like crazy once fully warmed with the use of royal purple. Mayb it could have been a manufacture defect or greddy trying to sell mobil1 to customers, i dunno.

i was wrong when i said mobil one have high viscosity. i really meant that it had a higher break down rate then RP, just quoting what the guy from greddy told me.

 

you guys should check this out: http://schneidercams.com/Warranty.htm

Schneider cams will void warranty on their camshafts if you use anything else than the oils listed on their website. and royal purple is on the list. Mobil 1 is not.

some other interesting reads on current blends of engine oils.....

Problem with running synthetic on an older motor is most of the time the engine has so much crud holding everything together (Seals and such) that when you switch to the better flowing synthetic that the engine may smoke leak due to it being able to carry more contaminates and such? make sense? if not I have been drinking so that's my excuse.

Ask Saab Tech's, Saab has been using Mobile 1 for a while now and now they are having a lot of problems with oil sludge and such causing problems

You will be fine with any oil, they are all great oils

I was gonna post about the crud build up but didnt want to make a long *** posta agin
