Help me break the bank and get in debt

Just don't use Mobil 1, use a decent synthetic and you should be fine.

A number of us on here run Shell Rotella 5W-40, and there are also people on here who swear by Amsoil.

Leaving the oil that's in there for break-in won't hurt anything. The important part is staying below 4k rpms and not running at any one engine speed for an extended amount of time (according to the Subaru manual).

 

Yes, as I mentioned, openecu has definitions to support the canbus ECU cars, so the 09 (and '10, after it comes out) will be supported for openecu tuning.

Yes really. Doing custom tuning is very hard on your car. The tuner will basically be doing many full wide open throttle runs from 2k to redline. Modern cars are a little better regarding break-in, but you for sure are going to want a number of miles on the car before tuning.

Regardless of what you do on day 1 of ownership, I'd recommend changing the oil at 500-800 miles.

 

ok that really threw me for a loop. isn't mobile 1, one of the few true synthetics? i know that the oil companies sued so that they could make semi-(fake)-synthetics (super reprocessed non-synthetic oil) and call it a synthetic because of how many times they refine the oil.

so why is mobile 1 bad?

 

It's contributed to the killing of a number of motors in the past. It tends to shear down pretty quickly, leading to spun bearings. Searching around on Nasioc will get you a number of threads about it.

 

Mobile one is the synthetic version of water.

 

I knew when he started talking about oil changes M1 was going to be brought up.

ofspunk7,

Here are some highly recommended thread reads:

and lets just get this one going too..

NICE



** also thanks for the threads. I did a search and have been reading since the last post. good thing work is slow today. i will check out those other threads. glad i said something about the M1. thanks again for the save on that one.

 

ok here is some outside feedback i got today

"Did a quick look
Shell Rotella 5W40 is primarily designed for truck and diesel applications, however, they do approve it for gasoline
engines.
Secondly, it is one of those "synthetics" that is not a true synthetics.
Its base is a XHVI group III, which means it is a highly refined petroleum product.
Mobil 1 is a PAO base group IV, which is a true synthetic product."


also what about the oil information on - www.motoroilbible.com

 

i personally run oil in my race car.

 

Do you mind if I ask why you're fixated on synthetics? Not meant to be a dig at all, just curious.

Trust me when I tell you that the Rotella will be much, much better for your car than anything marked Mobil 1.

 

I have a close family member that is pretty insane about oil. he has been doing research for the past 7 years. looking at the break down periods. the reason i brought this up was i know that the beter the liquid the better and longer my engine will run.

i like the info on rotella - but it is one of the oils that sued for the right to be called synthetic even though it isn't.

 

Run whatever oil you like. Just check your level often.

Don't try to reinvent the wheel with oil change intervals, even if some eBook told you to. Change at manufacturer's specs, especially during the warranty period (especially if 09's are still blowing, ringlands, was it?)

If you really want to know what's up with your oil, every couple changes send a sample off to Blackstone. They will tell you what's going on with it, and whether or not you can extend your change intervals.

 

i have no problem changing at the correct times, just want to do what is best for my car. I don't plan on runing 5k to 10k on the oil.

 

Rods and rod bearing issues on the 09 WRX's.

But yes, nothing incredibly special about oil. Use a decent oil and change it often, and your engine will be fine.

 

i think i'll pick the happy medium. my source says AMSoil or M1, because they are both true synthetics. every thread i have read today says AMSoil or Rotella. sounds like AMSoil is the way to go.

 

+1 for rotella. i switched over to it recently from m1. my car feels a lot better with rotella in it.

 

For a true synthetic, Amsoil or Royal Purple. I've used both with very good results on both. The car really seems to love the Rotella tho. Comes out alot cleaner than the Amsoil did.

 

Where are you guys buying the Rotella-T locally?

 

wally world

 

this is not true. it is a refined oil where they try and refine it enough to take the larger molecules out of the oil. these are the ones that break down quickly in regular oil. They only try to leave the shorter molecules. they actually took this to court saying that because they change the molecular structure of the oil it can be classified as a full synthetic when it really isn't. amsoil is a full synthetic.

 

Rotella was made for diesel engines which see a much much much harsher environment than our gas engines. 16:1 or higher compression and over 30psi, not including the soot. I will from now on run Rotella in my aggressive engine.

Just take your time on your mods. I understand that you want some rubles off the bat. $800 is a bit steep for a catback imho. If you can wait a month or two, you can get something nice for waaaay less money. Patience is a virtue in this world. I've been modding my car for almost nine years now.



Sounds like DarkDan is your family member. We had a little snit and I will never post on fivezeroseven again. That is all.

 

yeah I am not saying it is bad. I don't have anything to go on because i have never used it. i was just saying that it is labeled a synthetic because of some fancy lawyers won a case so they could market the label that way.

don't know who this person is. no my family member is like 50 and doesn't really do the forum thing.

 

I am not speaking with knowledge or opinion but when I purchased my 09 3 weeks ago...Subaru Dealer said Subaru DOES NOT recommend using a synthetic oil....just an
FYI..they also told me use BP or Shell gas only....just passing this along if someone wants to agree or not....

 

yeah i am sold. check the link a few pages back. there was a few pages about gas. it is weird because when it used to be Amoco i dated a girl in high school (like 12 years ago) and her dad would freak if she didn't take her mustang 5.0 to Amoco to get gas.

 

The early build 09s had issues with rods and rod bearings. Mine was a build date 08/08 and it went. The later build cars arent having the issue. Either way, its not a reason to not buy the car. If it happens, Subaru is very good at taking care of the issue, as well as the customer. If I could rewind and do it all over again, I would still sign the papers and take er home.

 

damn... see that i what i love about forums. you think you have a well rounded answer and someone goes and drops some knowledge on you turning your whole world upside down.

and I think i am going to just drink the sewage water and skip the OJ.
