SOURCE: what oil for my 1995 Subaru Legacy 250T?

I know I will get some argument on this one, but regardless of what manufacturers recommend, the best possible lubricant is a good synthetic. They far exceed any manufacturers needs in both lubricity long life and resistance to thermal changes. they do not burn off or form deposits readily and work in any temperature climate. as far as rating, a 10-40 or 50 works for everything. With synthetics those #s are almost a decoration on the can because in reality they cover a far larger span. Personally I would not use mobil1 (too much additive package not enough real stuff) on the other end, amsoil is one of the best (they even offer a 0w50 oil)
Whatever you use make sure you keep it clean. A good oil filter is essential and if extending oil change intervals, you can just change filter and any oil lost.
I know I've ranted, but the actual lab testing results and notes I've made over the years is far longer!
good luck whatever you decide on!

SOURCE: 95 Subaru Legacy loses power at stop lights after

I don't have enough information from you but here is my advice. Any sensor can throw the computer off coolant sensor, O2 sensor(s), MAF sensor. In your case it sounds like sludge or carbon build up. Start with the most basic and affordable things. Tune-up, intake, fuel, ignition and lubricants. Disconnect the negative from the battery to restart the computer, buy a new air filter, change the fuel filter, change the ignition coil, spark plug cables and spark plugs. Change the engine oil, filter and add Lucas, change the transmission oil, filter and add Lucas. If the car has the engine light on you can take it to Auto Zone and they will scan it for free, this will give you a hint to where to start. If no engine code give it a full tune up follow my directions. You have to give it a full tune-up. Since your vehicle is about 14 years old get the best and recommended lubricants and other tune up parts, don't forget the Lucas. Restart the computer by removing the negative or ground cable from the battery. This is a must for safety reasons but mainly because the computer is set to work with old spark plugs, clogged filters and whatever else you may have. Giving it a tune-up may not get rid of your problem completely but it will improve the situation noticeably. While doing the tune-up check for broken, cracked or swollen hoses, vacuum hoses radiator hoses etc. check any visible cables and anything out of the ordinary. These things can be done over the weekend or when ever you have time it don't have to be done in one day or have some one do it for you. Also there are other easy things to replace like the thermostat and PCV valve, these parts are part of the tune-up. To put it in simple words start with a tune-up before moving on, my recommendations is to guaranty it wont be a half-*** tune-up. There are tutorials on-line about Seafoam this is something I do recommend in your case. Its best if you take it to a shop and let the profecionals do it. If you don't feel comfortable putting chemicals in your car you can clean the throttle body by removing it and cleaning it by hand with throttle body cleaner. To put it back on replace any hoses and gasket attached to it with new ones. You can do the same with the EGR valve. Search on-line or ask around for ways to get rid of sludge and carbon build up. You can try the above but Subarus are infamous for idle problems.

SOURCE: how do i bleed my power steering rack on subaru legacy rs turbo

A power steering dosent need bleeding. If you replaced it a week ago and was fine until now then it's not an air problem. Power steering fluid is pumped through the system even when the steering is not being used. Definatly not an airlock problem. Cheer's

2002 Legacy 2.5,Auto,stubbles bad in low gears

I'm gonna do this from memory because my All Data is not working. I believe that the EGR is stuck open, your getting too much ERG or getting it at the wrong time. Easy fix either free up the valve test it with a vacuum gauge erase codes and try it out.
Use shop manual easy steps in doing this.
