This time it affects the 2013 and 2014 WRX and STI. Quote: According to the Subaru class action lawsuit, the rotating assemblies include defective connecting rod bearings, defective connecting rod side clearances, and/or insufficient channels of engine lubrication. As the connecting rod...

These VOA’s are courtesy of JarHams on nasioc and are posted in the Car Part Reviews forum there. The main reason for the voa’s is because Subaru of America sent a letter to dealers stating that the HPGO 75W-90 “is available as an alternative to the current K0322AA093 75W-90 Go Extra S Gear Oil...

I saw it mentioned on cars101.com and checked with SoA. I inquired if it had anything to do with the consumption/oil control ring issue. Quote: Dear Mr. bluesubie Thank you for taking the time to contact Subaru of America, Inc. regarding our recommendations for engine oil. Yes, for the 2015...

I know these are both good choices in a turbo Subaru, but I just thought I would share these entertaining (?) comments posted at nasioc. This thread was split off from the original thread because it went a little crazy. Quote: Not a fan of Rotella because it doesn't hold up well under high...

UOA by Oil Analyzers Inc. Previous uoa here. Driving conditions: Oil in use January - August 2012. This is my first full uoa after installing a Cobb Accessport and I am running the standard "Off The Shelf" tune which explains the increase (?) in fuel. Previously noted fuel levels were...

I found this on nasioc. The poster there had a noisy transmission in an Impreza. He called the dealer (I think it's a dealer) to ask what they used and they told him 50 weight gear oil. I think that woud have been better than whatever this is. 30 weight engine oil would have been better...

Ok, you Honeywell haters/Framophobes. You now have a new Wix optiIon. I was browsing nasioc's Newbie forum (of all places) and came across a reply stating that there is a brand new Wix filter with the Subaru 23 psi bypass seting that wasn't even in stores yet. The person did not state their...

This is my wife's car and she has AudiCare. It's driven about 25 miles each way to work and occasionally on weekends. The drive to work is hilly and twisty so the engine gets a good workout. I did a uoa to help me decide if I felt comfortable going to 10k miles as Audi recommends. As I...

UOA by Oil Analyzers Inc. Driving conditions: Oil in use since March 2011; 7 mile daily commute each way; spirited driving with a few redlines here and there on days where I have a 30 minute drive. A trip to SC during June. Most of my consumption is usually on trips if I’m driving on the...

UOA by Oil Analyzers Inc. Driving conditions: Oil in use since Sep 2010; 7 mile daily commute each way; spirited driving with a few WOT’s here and there on days where I have a 30 minute drive. In October, a trip to RI and to the White Mountains of NH (fun mountain driving). Most of my...

UOA by Oil Analyzers Inc. Driving conditions: Oil in use May – September; 7 mile daily commute each way; spirited driving with a few WOT’s here and there on days where I have a 30 minute drive. A trip to RI in May and to SC in July. Most of my consumption is on trips after driving on the...

1. Subaru Forester 2.5 XT (EJ255=STI block, different ECU, different intake manifold, and a WRX turbo) 2. API SL/GF-3 5W-30 recommended for fuel economy; 10W-30 & 10W-40 allowed over -4F; some straight grades and 50 grades also allowed in severe conditions. Subaru now recommends 3,750 mile OCI's...

UOA by Oil Analyzers Inc. Driving conditions: Oil in use Nov. – June; 7 mile daily commute each way; a couple of days driving on the beach, no mods but spirited driving with a few WOT’s here and there. Oil changed but filter not changed. My last uoa is here . Sodium dropped nicely so it looks...

UOA by Oil Analyzers Inc. Driving conditions: 7 mile daily trips; driving on the beach; several days of 100F+ temps (including one week vacation in SC in June with heavy load); towed a guesstimated 1,400 pounds 200 miles to Rhode Island in Sep; no mods but spirited driving. OEM turbo was...

This is not my WRX, the uoa was posted on nasioc.com: Stock car, OEM air filter, Purolator Pure one oil filter, lots of stop and go driving during the daily commute. M1 5W-30 went in again. Miles on oil: 4,900 Miles on motor: 70,700 Element Value (Universal Average) ALUMINUM 2 (3) CHROMIUM 0...

I hope this isn't a re-post, but I just found the recommendation on amsoil.com. I'm a bit surprised by this but I guess they're covering themselves. IMO, the bulletin came about due to owner neglect and/or modified engines without a modified oil plan. My dealer's head master tech has only seen...

My OEM turbo was replaced under warranty about 4,000 miles ago due to excess oil getting past the turbo seals (intermittent problem for a year). I had just switched to SSO a couple of days before the oil change and the head tech at my dealer said I was fine leaving the SSO in there. Originally...

This is not my uoa. It was posted on nasioc and is a very popular cocktail used by folks looking for the right combination of friction for the synchros and protection for the gears (hopefully). It is known in the Subaru community as "Uncle Scotty's Cocktail" and I know that there have been...

UOA by Blackstone and oil was in use March to December ‘07. My usual slightly elevated fe and si, presumably due to my five mile daily trips. Late July summer vacation to Myrtle Beach, SC and the Outer Banks, NC saw a few days at 100F. 2,000 miles on that trip. Also did about 20 miles of beach...

UOA by Blackstone and oil was in use December 23rd to March 6th. I was pleasantly surprised with this UOA because I suspected that oil with a viscosity of 9.9 cst’s at 100C would shear to a 20 weight. I switched to the Motul because I was having high fuel dilution during the winter due to my...
