  1. My BEST mpg city is 19, worst is 18. My best mpg highway is 24. This is significantly off from the EPA estimates by about 20%. This is calculated using the method of filling up and dividing by miles driven since last fillup.

     

    I have the identical problem to you (and have started at least one thread like this one which you've probably read!). My '98 Legacy L wagon with the 2.2L, 1-year old Nokian NRW tires, and a rebuilt 4EAT gets 21-22 mpg highway :banghead: traveling between 60-70mph.

     

    I have: cleaned the MAF, changed the air & fuel filters (OEM), have new plugs & wires, a new front O2 sensor, tried synthetic gear oil (Royal Purple 75w90) in front & rear diffs, tried synth oil in crankcase (pennzoil plat 5w30), semi-synth ATF (Specialty Formulations Autoglide) in the tranny, and maybe one or two more things I can't recall.

     

    Benefits of all this: synthetic gear oil helps with steering effort in low temps , same with using synth ATF (I use Royal Purple MaxATF) in your power steering. The Autoglide stuff makes the tranny shift very nicely. No difference with synth oil, except for louder startup piston slap. Havoline dino 5w30 makes the engine run nice & smooth and is just $1.40 a quart. ZERO effect on mpg's, unfortunately.

     

    Oh yeah, I'm in the midst of an AutoRX cycle (www.auto-rx.com) to clean out the engine and see if that helps. So far, nothing to report.

     

    About the only things I haven't tried are ultrasonic cleaning of the injectors and replacing the rear O2 sensor. I came across a post recently that claimed the REAR sensor is the culprit for the gas smell when cold: http://www.ultimatesubaru.org/forum/showthread.php?t=43624&highlight=outback+sport

    Easy diagnostic on the o2 sensors, if you are bogging down and shuddering on the low end, but dissappears with higher RPM's... Most likely o2. If you get bogging all over, fuel issue. But, if you can idle INSIDE an OPEN garage for about 20-40 seconds, shut off, get out and smell gas... You prolly need some new o2 sensors.

     

    Also, some people around here are under the impression that only replacing the front o2 sensor will quell your probs... They are mistaken. I tested that theory on a couple of tanks of gas. Save your self the time, $$$, and trouble and do both at once. OEM ONLY FOR THE REAR.

    Once my work bonus arrives just before Xmas I will invest the $85 in an OEM rear O2 and see what happens.

  2. this is all over the place. i would never ever expect any oil to last 10,000 miles, i dont care what the mfg says. 6000 miles is pushing it, as about that time all the additives are gone. Since most people always let thier oil changer go a little farther then they should, i would say 5000. DO a search for this topic, you wil find tons of information pro and con. Longer oil change intervals also allow for small problems to become big ones. a leaking fuel injector that may get caught at a 3000 mile oil change can destroy and engine at 7000 miles or more on the same oil.

    This is a case of penny wise dollar foolish, If you are doing it to save costs up front, it wil cost you later in an spun bearing. ALso another thing to remeber is that the filter may not be rated for 6000 miles, and you may still have to do a filter change before an oil change.

     

    nipper

     

    Actually there is a way to tell what the best oil change interval there is for your car - a used oil analysis. You can buy an oil extractor pump that'll pull out the 3-4 oz you need, so you can get a UOA without changing the oil. Places like Blackstone Labs will then do a UOA for about $20.

     

    The recommendation of the oil nuts over at www.bobistheoilguy.com with regards to extended drain intervals is this: do a UOA to determine what works best for your car, oil of choice, and driving style. You can't tell the condition of oil by its color or appearance. Go 3k, sample, test, repeat at 6k , whatever.

     

    Subaru engines are very easy on oil, as it turns out, and extended drain intervals are certainly possible, as much as 10k or more - but test to be sure. Once my current run of Auto-RX (www.auto-rx.com) is finished next fall I'm going to give Castrol Syntec 0w-30 a try, run it for 5k miles, do a UOA, and then probably go to an annual oil change which is ~7k miles in my case.

  3. The best single tire out there is the Nokian WR "All-Weather Plus" these are the only tires out there that are true all-season with the winter rating.

     

    Or like others have said, get a set of cheap used snow tires of ebay or craigslist.

     

    I concur on the WR's if you want a year-round tire with fantastic snow & ice handling. I have their predecessor, the NRW (they don't do the WR in 185/70R14 :() on my Subaru and the car is fantastic in snow, rain, and ice. Really unstoppable, although I must say my Nokian RSI equipped FWD Saab 9-5 does just as well in the white stuff. Previously my car had a set of the OEM Firestone all-season tires - the difference between those and the Nokians was night and day when the going got tough.

     

    As for the comment that 'if you can do FWD in winter, you can do a sub in summer tires': this is probably the worst advice I have ever seen on USMB and I hope the poster was kidding. AWD does not make summer tires stick in cold weather. AWD is an aid in poor weather conditions, it's not a panacea.

     

    Nokian WRs aren't cheap (14" ~$80 ea) but you can use them for several years year-round and won't need another set come spring. Think of them as an investment in your skiiing, or, think of them as costing a ski trip.

  4. the GT rear bar is SMALLER in diameter than the Outback

     

    the OBK rear bar is what I installed on my 99 GT

     

    GT rear bar = 16mm

     

    OBK rear bar = 18mm

     

    GT front bar is 20mm - - that's plenty beefy.

    no need to upgrade there unless you're racing the car ;)

     

    Ok, so there are several possibilities: L front with GT or Outback rear, or GT front with GT or Outback rear. Just adding an Outback rear swaybar would probably be the easiest. Would a GT front + Outback rear be too much? I'm not looking for massive oversteer here, with the 2.2L and an auto tranny this is not a raceworthy car :lol:

  5. I think I will be replacing the front struts & shocks on my '98 Legacy L in the springtime. I think I can get one more winter out of 'em... I was thinking about upgrading the swaybars at the same time. I know that replacing the rear one with one from an Outback of that vintage improves body roll. What about the GT rear bar -is it the same as the Outback?

     

    What about the front bar? After browsing http://www.subarugenuineparts.com it appears that the GT & Outback have a different swaybar than the L. Is it worth the effort to replace the front bar as well?

     

    My plan is to use the OEM springs and the KYB GR-2 struts from Tirerack.com.

  6. Greetings:

     

    After shopping online for several days at Discounttiredirect, Tirerack and Tiresaving, I am still hesitating between these 3 brandnames. Beside Bridgestone, I never heard of the other two. Surpprisingly, none of these web-sites suggest Michelin. Are Michelin really that bad?

     

    Kumho ECSTA ASX ~$435

    Avon Tech M550 A/S ~$502

    Bridgestone Potenza G009 ~$569

     

    I have the Avon summer performance tires, the M500's, that I use on my Saab. They are terrific tires, with tons of grip in the wet and dry. The word over on Saabnet.com is that the M550's are also very good all-seasons.

     

    Edit: comment on the Avons from saabnet (http://saabnet.com/tsn/bb/9-5/index.html?bID=121243) - I just replaced my Aero's Michelin Pilots with a set of Avon all season tires and I must say they are unreal. Less noise and a better ride. I have about 500 miles on them and the ride and wet traction is great. I am amazed, even after all the other reviews, that these are tires are as good as they are.

  7. I know there was someone on here a few years ago that did this with a late 90's Legacy or Outback. They just didn't bother with the high beams at all. With the HID, virtually unnecessary. I recall seeing some bulbs that piggybacked a standard Halogen high beam onto the HID bulb, but I have no idea how good they were.

     

    Aren't the HID retrofit kits off the market? I thought that some regulations changed a while ago that prevented them being sold anymore. ??

     

    Commuter

     

    All About HIDs:

    http://danielsternlighting.com/tech/bulbs/Hid/HID.html

     

    Can I convert my halogen headlamps to HID?

     

    So you've read about HID headlamps and have it in mind to convert your car. A few mouse clicks on the web, and you've found a couple of outfits offering to sell you a "conversion" that will fit any car with a given type of halogen bulb, for between $900 and $1300. STOP! Put away that credit card. Trying to "convert" halogen headlamps to HID is an unsafe thing to do. There are *NO* legitimate or safe HID retrofits for the headlamps of any car which didn't have HID lamps as a factory option.

     

    If you have the 95-97 headlights, there are much brighter H4 bulbs are available. If you have the 98-99 Legacy lights, you can retrofit the older lights.

  8. I have already pulled the codes, and I know what they are.

    I have also removed the intake tube from the back of the MAf while it is running to isolate the sound and it is coming from the Maf tunnel.

    throwing a CEL is no big deal.

    Pull battery cable off for 30 minutes reconnect , dont touch anything , turn off once warm.

    ECU reset.

    Anyways.

    Thanx

     

    I have the identical issue on my '98. I recently replaced the K&N air filter with a run of the mill STP, having lost faith in the K&N's filtering ability after reading about many tests of it. The air box is tightly sealed, along with the tube to the air reservoir...I'm thinking I may peek inside the air box to make sure the filter is seated correctly.

  9. The tranny oil pan based sensor gives you a slower, average and lower reading. The line sensor gives you max oil temp and shows you quicker temp spikes.

    I have mine in the line. Fast driving is up to 160F (i have a medium sized tranny cooler). Towing, especially when hilly, spikes the temp to 210-220F easily. I use synth ATF BTW.

     

    Could you describe how you installed it in the line? I haven't looked at the fluid lines to the radiator so I don't know how big they are, and I also don't know how big these sensors typically are...

     

    I just switched my car over to Specialty Formulations Autoglide ATF, a semi-synth, high quality fluid that's about $5/qt after shipping. Shifting is greatly improved over the dino ATF the tranny shop put in, especially on those chilly mornings.

  10. I recently did this on my Toyota RV. I couldn't find a sensor that mounted on the pan (besides, there were significant concerns about where and very low clearances). I found a sensor/guage kit for around $60 where the guage mounted in-line with the tubing which carried ATF to the front cooler in the radiator. The only trick there was deciding which line was the "hot" line going into the cooler so as not to mount it in the "cool" line returning from the radiator. Other than that it was a pretty straight forward installation. I found it useful on the RV because of the amount of weight of the motorhome on an engine/tranny originally designed for a light weight truck. I also added a cooler which was even easier to install.

     

    Where'd you get the sensor for that location? I'm really mostly looking to keep an eye on my rebuilt transmission - after sinking $2400 into it last January I figure a $50 gauge is cheap insurance. I was looking at the Cyberdyne gauge at http://www.egauges.com.

  11. My legacy wagon is a 2.2L, automatic. What size is the fuel tank for this particular model? I'm concerned about mileage. i'm not totally sure what the mpg should be, but we're getting around 20-ish miles to the gallon. I don't seem to remember ever putting more than 9.5-10 gallons in for a fill-up. Not sure if it's a faulty fuel guage or not.

     

    Join the club...there are many here who get poorer mileage than they should on the 2.2L auto. My '98 gets 21 mpg on the highway...there are many things you can try to do to improve it, the search feature will turn up many ideas. I calculate the mileage from the odometer & the amount I add when I fill up.

  12. Just wondering if anyone has some tips on driving through deep snow?

     

    How much can you expect to be able to navigate through in a Suby Legacy L?

     

    Ok, second question.....Nokian Hakka 2's, or RSI's for best tread life, variable driving conditions, and long commutes??

     

    I would hesitate to go through snow that's much deeper than your ground clearance - these cars aren't plows :-) If it's light and powdery, you could do more snow.

     

    I used a set of Nokian RSI's last year on my wife's Saab 9-5. They were astonishingly good, quiet on the highway, made 6" of fresh snow feel like dry ground. I wouldn't hesitate to get them if you're not going to stud 'em.

  13. 22 mpg highway, '98 2.2L auto, 112.5k miles. I have had a tranny rebuild, new O2 sensor, new plugs & wires, new air & fuel filters, new PCV valve, new engine temp sensor (that got me 2 mpg). I also have synth oil (royal purple 75w90) in front & rear diffs, and synth oil (Pennzoil Platinum 5w30) in the engine.

     

    I am currently doing an Auto-RX cycle (http://www.auto-rx.com) to try to improve things. Yes the stuff works, go to http://www.bobistheoilguy.com for info.

     

    My next step will be a set of rebuilt, cleaned fuel injectors serviced by http://www.rceng.com or someplace similar.

  14. With the left side sagging on my '98 Legacy L, I think I will need to do a new set of springs all around sometime in the early spring. With 113k miles on the original shocks, I'll do those at the same time. I've got my eye on the KYB GR-2 aftermarket shocks for a slightly firmer ride.

     

    What aftermarket shocks are available for this model & year? I'm looking for less body roll and a more responsive ride. Or is the GR-2 with ($60 ea) OEM springs a good enough upgrade?
