ehsnils Posted September 25, 2011 Share Posted September 25, 2011 Should there be a difference in oil weight used in the rear diff? Based on outside temps Since it's specified as a multigrade oil you shall be fine in all the temperatures the car is specified for. Link to comment Share on other sites More sharing options...

4Rings6Stars Posted October 20, 2011 Share Posted October 20, 2011 Just read through this thread... I bought an 06 recently that had a bad turbo (got a good deal on it). I had the dealer replace the turbo / flush the oil system and I was told the same thing mentioned above - DO NOT USE SYNTHETIC. I've never worried about oil before in my Audis (non-turbo) and now I'm paranoid that not using the correct oil will kill my new turbo... I'm not sure what oil was used for the first 88K miles but given that the turbo was junk as a result of "using the wrong oil or not changing frequently enough" (according to the mechanic at the dealer) I'm now paranoid! At this point I'm thinking I should: start using 5w40 synthetic and change every 3K. Does this make sense? Link to comment Share on other sites More sharing options...
NWSPECB Posted October 20, 2011 Share Posted October 20, 2011 That's what I do..granted I Havnt had the car long enough to have any problems arise out of this but there is a lot of faith in the rotella t6 5-40 synthetic. Link to comment Share on other sites More sharing options...
ehsnils Posted October 20, 2011 Share Posted October 20, 2011 The "Do not use synthetic" is just bullshit. As long as the oil conforms to or exceeds the specs required you are good. 5W40 is fine, but also check the other specs. Link to comment Share on other sites More sharing options...

I don't understand - is it some global conspiracy where Subaru dealers want us to use regular oil? There has to be some reason behind it...profit motive? Why not say that all Subarus should use regular oil? Or do they think that because most people don't understand turbos they can slip it by them?

ehsnils Posted October 20, 2011 Share Posted October 20, 2011 If you have free service then the dealers don't want to use the top line oils but the cheapest oils that they can get away with. Link to comment Share on other sites More sharing options...
epic legacy Posted October 25, 2011 Share Posted October 25, 2011 Subaru dealers do have a "subaru brand" Synthetic that they use on their newer cars. This came of a dealership website. "All 2011 & 2012 Subaru Foresters, 2012 Subaru Imprezas and all turbos are REQUIRED to use synthetic oil." Link to comment Share on other sites More sharing options...
GeraldG Posted October 25, 2011 Share Posted October 25, 2011 That's odd. Saw this at the dealer and it didn't say that 2011 non turbos needs synthetic. And the synthetic oic is 7.5k?! Wow. http://i146.photobucket.com/albums/r254/ggar015/c1135704.jpg Link to comment Share on other sites More sharing options...
DirtyDan Posted October 25, 2011 Share Posted October 25, 2011 7,500 miles? Not in my turbo engine. I've gone that far in my old Chevy truck with a stock motor that never sees more than 3000 rpm, but only once. Link to comment Share on other sites More sharing options...
ehsnils Posted October 26, 2011 Share Posted October 26, 2011 They state 15000km (roughly 10000 miles) for the diesel. But I had my first at 6500. Link to comment Share on other sites More sharing options...
ssbtech Posted October 26, 2011 Share Posted October 26, 2011 140,000km on my XT, still not burning any oil. The level never drops below the full mark on the dipstick. Am I just lucky? Link to comment Share on other sites More sharing options...
captainobvious Posted October 29, 2011 Share Posted October 29, 2011 A friend of mine had a Forester with over 165,000 on it and he says that i should use synthetic 10w40 for my Turbo. I plan to do all the fluids with AMSoil in the tranny, the diffs and the Oil change. Link to comment Share on other sites More sharing options...
Max Capacity Posted October 29, 2011 Share Posted October 29, 2011 (edited) I'm using Amsoil 5w-40 European in my 09 Spec B with Amsoil Sever Gear 75w-90 in the Tranny and rear diff. HAMMER DOWN got me on the stuff. He's over 177,000 miles on the 0w-30, check out his post on here. I also use Blackstone Labs for my oil Analiese. My 05 has what ever 5w-30 or 10w-30 or Rotella 15w-40 conventional oil and Amsoil Sever Gear in the tranny and Extra-S in the rear diff because I had a bottle left over. If It didn't the replacement rear diff would have Sever Gear in it.

planelazy Posted November 3, 2011 Share Posted November 3, 2011 I go 50,000 miles between oil changes.. ..on my semi-truck I change my oil about every 4-5 months, which is usually around 2,000 miles or so for me. Link to comment Share on other sites More sharing options...
Alopez6337 Posted December 6, 2011 Share Posted December 6, 2011 I just bought a 07 legacy specB with 89k on it. ill be doing the first oil change this weekend. Ill probably be running 5w40 Motorcraft syn-blend and see how it goes. Yea i know everyone is talking about M1, royal, rotella but ill go with motorcraft mainly because I work a ford dealership in northeast atlanta and it comes cheap with my discount and its pretty realiable. Ill keep you guys posted on how the motor likes it and see where I go from there. Link to comment Share on other sites More sharing options...

akula Posted December 9, 2011 Share Posted December 9, 2011 Ok, OT post warning but w/ all the oil interest I figured I could get a valuable response. Been using 10w/30 amsoil for a while since it has the best thermal and wear properties I could find from the amsoil lineup suitable for the 2.5gt. Problem: My 05 oil consumption has gotten worse over time but was always bad ever since I bought it used. I'm now at a quart every 2-3 weeks of sporadic use cycled in w/ my other cars. Recently I've begun to notice burning smells, perhaps oil, inside the cabin on sporadic occasion, sometimes puffs of smoke from the hood scoop after stopping at a red light. I pull over and pop the hood and NEVER see oil drips, oil gushing or leaking anywhere from above or below. If it's leaking it burns up as soon as it contacts something, perhaps the exhaust manifold? I can't figureout where the hell my oil is going! Btw, car passes smog in CA. Thoughts appreciated. Link to comment Share on other sites More sharing options...

Anyway's, it's most likely a valve cover gasket that's leaking. How many miles on it ? My 05 uses oil too. I can smell burnt oil a couple times a week. I also smell power steering fluid. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

ehsnils Posted December 11, 2011 Share Posted December 11, 2011 I agree that the valve cover or spark plug well seals are the most likely culprits - unless there is a driveshaft boot that has gone to it's ancestors. Link to comment Share on other sites More sharing options...
roundthirteen Posted January 2, 2012 Share Posted January 2, 2012 (edited) Does anyone have an opinion on Red Line VS Mobil 1. I know y2kimports.com swears not to use synth but isn't that what came in the car???

DirtyDan Posted January 2, 2012 Share Posted January 2, 2012 Redline is an excellent oil. Mobil 1 depends on which one you are referring to. Mobil 1 15,000 mile is the full synthetic, the other 2 (5,000 & 10,000) are mineral/synthetic blends. Anyone that tells you flat out, not to run synthetics is an idiot.
