ok I have used mobil 1 for the past 2 years in my eclipse, now i put it in my 7000 mile 2007 wrx and at first it ran a little wierd, i had to give the car a bit more power to get going and it burned oil in about a week, i had to add an extra qt. I let the car warm up 1 minute and drive slow for the first 5 minutes of driving before i decide to even punch it just a little bit to 5k rpms, today i was running some errands and decided to speed here and there between freeway's and now i needed to add an extra quart. After hours of reading I finally decided im done with mobil1 5w30 for this car, there are just as many bad posts about it as there are good posts, so now im just here wondering if this combo seems good
Redline 10w40
Pureone oil filter
if you have something better in mind let me know ill take it under consideration.
It's always been my understanding that your not supposed to put synthetic in a new car until it reaches 10k miles. This allows the engine to properly break in.
My tuners are part of Subaru Canada's Rally Team ... I was having smoking issues with my02 wrx. First thing they asked was if I used Mobile 1 at any time. After explain that I have never used Mobile 1 in the Suby we discovered that my smoking was coming from the oil seal within the turbo. Anyways ... long story short, They tell me that all the Suby's that they have/use/abuse all use ELF 10W50 which is a full synthetic during the hot summer months and suggest not using any other brand. Little bit more expensive but worth every penny!
Redline oils are great in fact i sell them in my shop. A lot of it has to do with weather conditions. where I am during the summer tends to be hot and humid ... 10W50 or the 10W40 should be fine. in winter when its DAMN COLD I would use 10w30 or 5w30 full synthetic.
would you recomened 10w30 or 10w40 for a stage 2 wrx? the temperature here ranges from 65 degress in the morning to maybe 80-100 in the afternoon but lately its been in the 80's
not sure, i need to change my oil soon im at the 2800 mark, still deciding between 10w30 and 10w40, after seeing that post i want royal purple but i thought royal purple is only gl-4 rated and we needed gl-5 rated oils
Subaru recommends an ILSAC GF-4 grade oil or API SM oil marked "Energy Conserving". As for viscosity, Subaru recommends 5W-30.
Keep in mind "True" synthetic oils are Group IV oils that have a base stock of PAOs. Mobil 1 is classified Group III, and it's base stock is factionally distilled petroleum that has been hydrocracked.
I use Royal Purple in my STi and I love it. I switched from Mobile 1 and I won't go back. The car seems alot "happier" and more smooth than when I was using Mobile 1. It is expensive (about $7-$8 a qt) but worth it in the long run.
guess im going royal purple for sure now after alot of reviews and reading, alot of people are running royal purple 10w30 what do all of you run with royal purple?
well upon hours of research on nasioc.com i decided to just go with what i had locally and bought redline for 29.99 for 4 quarts, and another single qt for 7.99. I decided to run 10w30 for now and maybe next oil change ill goto 10w40, if i like it ill stay with it forever probably. Btw if your looking for royal purple or redline i noticed alot of "local" stores such as monument auto parts or stockton auto parts carry this stuff rather than autozone or kragen n such. The guy at the store offered me a K&N oil filter, walked straight out the door =) Anyone agree that pureone filters are 2nd best next to the new subaru oem ones?
Interesting post.
I was just in for my 1st oil change @ 3k mi, on a new '07 wrx.
when i pulled into the bay at the dealership, they asked if i wanted a blend of conventional/synthetic...
they recommended the blend and for an extra $6, i had it done. any opinions?
Castrol GTX you mean. anyway, Robby, where do you buy your Purple? i know that Summit sells it, and Pep Boys. I've been contemplating about changing from Mobil 1, and Wal-Mart sells it for 6.76 i think. only in 5w30 though. will it make a difference if its 5w30 or 10w40? because that picture showed the 10w40.
I'm pretty erked right now because i just changed my oil friday.. damnit.
I switched to Royal Purple and a PureOne filter at my first oil change at 1000 miles and the car has been nothing but happy.
