Merc6 Posted June 16, 2010 Share Posted June 16, 2010 I believe the part # is not the same because the engine oil filter has "engine" written on it and the transmission filter has "transmission" written on it. Otherwise, I believe the construction is probably the same. On Amsoil's site, it recommends the same filter for both the engine oil and transmission fluid. Yeah I wasn't gonna stick a $50 blue fram (or wal-mart fram) one on there. This one didn't say tranny clearly like the one pictured on FBP thats why I asked. If I used the factory $7 qt subaru fill I could just change it out every 4 oil changes if it was that serious. Thank god this wasn't GT-R tranny fluid! 2005 Satin White Pearl Subaru Legacy 2.5 GT Unlimited 5EAT (Project Car) 2019 Agate Black Ford Explorer XLT 4WD (DD) Link to comment Share on other sites More sharing options...
apexi Posted June 17, 2010 Share Posted June 17, 2010 I'm surprised blackstone hasn't gotten back to you yet. Mailing from PA to IN shouldn't take very long, and blackstone usually has quick turnaround after they get the sample. Link to comment Share on other sites More sharing options...
JoeFromPA Posted June 17, 2010 Share Posted June 17, 2010 I've seen them take up to 3 weeks. Mail can take up to 1.5-2 weeks to get them, normally. On the flip side, I've seen them do 4-5 days. Link to comment Share on other sites More sharing options...
bluesubie Posted June 23, 2010 Share Posted June 23, 2010 This is random, but in follow-up to a bet I made with Unclemat about 9 months ago, I ran Castrol GTX 10w30 for 3500 miles and sent in a sample to Blackstone to see if it sheared down a grade (thereby showing whether or not a solid dino was capable of holding it's viscosity in our cars over the recommended interval). Sample sent in 8 days ago, just waiting for the results. My prediction is 9.1 cst's. Although it would have been another 250 miles for the recommended interval. -Dennis Link to comment Share on other sites More sharing options...

ShrinerMonkey Posted June 24, 2010 Share Posted June 24, 2010 I switch between Valvoline Synpower and Penzoil Platinum depending on which I got on sale. I have a 2.5i and I change the oil once a year as I don't usually drive much over 6000 miles a year. Link to comment Share on other sites More sharing options...

TheWeatherWarrior Posted June 26, 2010 Share Posted June 26, 2010 I go for between 3500 to 4500 using non-synthetic (yet). Just rolled over 101k (only 12k since purchase) so may stick with the 3000-3500 on synthetic. Link to comment Share on other sites More sharing options...
addison Posted June 26, 2010 Share Posted June 26, 2010 ^Good oil, and I am not being sarcastic. its cheap and readily available too so i use that to justify changing it every 2.5-3k even tho it could easily last 5k+ no problems Link to comment Share on other sites More sharing options...

Max Capacity Posted October 4, 2010 Share Posted October 4, 2010 Wow after all these years I just found this thread. 132,000+ miles, I use Fram oil filters, whatever 5-30 or 10-30 is on sale at Walmart like Mobil 5000 or Shell. This April I started using Shell Rotella 15-40. I check the oil every few days and alway's top it off as needed. Change the oil anywhere from 3000 miles in the summer to 5500 miles in the winter. Been at stage 1 since Dec 04 and stage 2 for about 5 weeks now. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD).

Soda Popinski Posted October 4, 2010 Share Posted October 4, 2010 Still runnin Motul 5w30, doing oil every 4000ish. Still adding around 1qt per 1000 miles after though. I'm not sure why the motor uses that much oil. Link to comment Share on other sites More sharing options...

I'm not sure why the motor uses that much oil. Have you tried switching up to 10w-30? Esp in the warmer months. All I need now is a hill holder and a center passing light...

Max Capacity Posted October 4, 2010 Share Posted October 4, 2010 I believe most of the oil useage in blowby. Talking with a Machine Shop that does most of the Subaru rebuilds from the local dealers he say's they use a soft ring on these motors. Just keep checking and topping off the oil as needed. Glad I use cheap oil. I'm close to most, useing about a qt every 1000 miles. I don't both to firure the actural usage out. Just keep adding, I think of it as the engines alway's getting fresh oil instead of having the smae old stuff in there for 3500 miles. You need to rationalize. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

Polo08816 Posted October 5, 2010 Share Posted October 5, 2010 Still runnin Motul 5w30, doing oil every 4000ish. Still adding around 1qt per 1000 miles after though. I'm not sure why the motor uses that much oil. I have a 2008 LGT 5EAT with about 23,000 miles on the ODO. I do 5000 OCI using Amsoil oil filter and M1 0w-40. My engine does not burn oil at all. Maybe if you tried a higher weight oil it would burn less? Link to comment Share on other sites More sharing options...
Polo08816 Posted October 5, 2010 Share Posted October 5, 2010 OEM ATF is just fine, as a matter of fact many aftermarket fluids aren't up to spec. If you want to go with a tried and true synthetic, get an Amsoil flush. I don't think the ATF filter is the same as the oil filter. You are looking at the one located under the battery, correct? Last I replaced it, 3 years ago, the part # wasn't the same and it was a bit more spendy. It's not the same part number because the ATF filter has "transmisson" written on it. I can't imagine the construction of it being different than the engine oil filter. Regardless, I'm using a regular oil filter for it. lol. Hopefully it doesn't become an epic fail.

HAMMER DOWN Posted January 9, 2011 Share Posted January 9, 2011 Wow after all these years I just found this thread. Almost 155k, my OCI avg.12k with Amsoil 0w-30 SSO & Ea oil filters( filters down to 15 microns. And down to 2 microns with a by-pass filtration which I run. http://legacygt.com/forums/showthrea...11#post1715611 Cobb st1 93 map, max boost is still 16.2psi.

That is also on my car now. Earlier someone said amsoil has the same part# for them both but subaru doesn't. The tranny one from subaru is like $45+ and engine is like $7. I was gonna swap for a K&N or something not fram like. 2005 Satin White Pearl Subaru Legacy 2.5 GT Unlimited 5EAT (Project Car) 2019 Agate Black Ford Explorer XLT 4WD (DD) Link to comment Share on other sites More sharing options...
