SOURCE: Oil Change queries SUBARU IMPREZA RS 2.5 2005 MODEL non turbo

I am confused - I have a simple query and logged on to your site as you offered free advice! Do you not offer the service as described on your website. I definitely don't need a team of experts to answer my very simple question.

SOURCE: 1995 Subaru Legacy oil and filter

Oil is 10-30 and the type of oil filter is up to you, you can go cheap or you can go expensive it is all up to you what you want to run in your car.

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: Cause of noise in front differential of 1997 Subaru Legacy Outback.

there is a plug on the shaft-side of the differential. Using a ratchet remove the plug and with the engine OFF, stick your finger inside the hole and you should get fluid just below the threads of where the plug goes in.

No power going to rear wheels

is your car a rear wheel drive vehicle? if yes, check your drive shaft, it might already be disconnected to the transmission or differential. Transmission is the one attached directly to your engine, differential is attached to the rear wheels.

I changed my oil last night with my boy friend who does frequent oil changes. Afterwords, my transmission started shifting extremely hard and late. Please help. I do not believe he drained the tranny...

e: subaru legacy transmission dipstick Transmission dip stick is behind the engine in front of driver side firewall. Move a few hoses out of the way, look down and you'll see it has a yellow top.
Other side (passenger) lower down yet, again move a few hoses aside, yellow top handle, you'll find the shorter differential dip stick.
In either case, if your gaze reaches the ground, you've gone too far.

Automotive problem. 1991 Subaru Legacy C

Lubricant may not resolve it sounds like it could be your water pump froze up. Look to see if it is turning. Even if it turns it still could be bad.Usally the first sign of it going bad. Stop by your local auto parts store to see if they agree.

Turbo 2ooo i think it might be some sort off bushes

juddering is UK english for shuddering in US english. The center bearing shouldn't move, i/e/ the shaft should rotate w/o side play in the bearing, but the rubber mounts for the bearing should be flexible. The needle bearings in the universal joints in the front to rear drive shaft can go bad, causing noise when accelerating and they're not changeable w/o special tools. Your problem also sounds like differential, which would mean that you need to change the gear oil in the rear differential. As the oil ages it stops working properly in the limited slip differential even if visually OK. Do the front differential at the same time, engine heat ages it even faster. The center diff is in the AT, so you would change the AT filter and fluid.
How to tell which problem you have... in a parking lot with dry pavement, stop the vehicle, turn the wheel hard right, accelerate a moment, and repeat hard left and centered. If its worse turning, than straight suspect the differential fluids first. If its the same turning or not and especially if its the same on wet or dry pavement and at slow and high speed then look into the propeller shaft first.

Steering

There are a couple of causes, and the solutions in order of cost are to first change the gear oil in the front and rear differentials and drive a few miles, then the transmission filter and fluid. finally consider "the infamous torque bind" as detailed at http://legacycentral.org/library/torquebind.htm, but a '91 is very likely to have been resolved by changing the differential fluid.
