You even contradict yourselfAnyway, can of worms

guys i think your getting a little confused as to why you would use the thicker grades.thicker 50&60 grade oils are used in cars that see high (100+c) oil temps.
At 120c even 60 grade oils have simillar viscosity as 30 grade oils at much lower temps.
at those temps the oil has a very hard life and ages very quickly. a 5-40 is perfect for a road car though(use it myself)although i do change mine every few thousand miles.

Hmmm, and yet you're the one posting on all the forums.Anyway, I go off experience and have had Imprezas since the very first Impreza Turbo came to the UK but still have limited knowledge and I dont say it as fact, just as an helpful idea.
Its well known in the scooby world of 0/5w fully synth oil can be too thin and gets past oil seals
This is not the case with them all just where owners have had issues it has sometimes been due to the oil they have used, in many cases it was mobil 1, at that time I opted to use Shell helix 10/40 or similar hence my post
No point going on about friction science, I didnt say put chainsaw oil in it
Well thanks for all the advice so far guys.
After doing 270 miles with nothing changing I have decided to keep an extremely keen eye on it. It is sat at a smudge above middle. I'm trying to convine myself that the times it's been low the car has been on a slight decline. I have another few hundred miles to do at the weekend so we'll see how it goes.

Some time back Subaru released a tech bulletin advising that all Subaru, classic and newage should now be using 10W40 fully synth, not 5W30 semi-synth.
Your average scoob should be very happy on a good quality 10W40 fully synth, and modified cars should consider a good quality 10W50 or 60 depending on how hard it's used.

People have their favourites but any good quality will do. There are so many to choose from and a lot of them are much of a muchness really. You seem to be using a bit though so i wouldn't go overboard until you know what's what. Halfords do a perfectly good 10W40 Fully synth that would do you. Once you know what the score is or have established there is no leak or fixed the leak, then do an oil and filter change and use the really good stuff.
I'm going insane with this. I'm checking too much and not surprisingly the level is never exactly the same. I don't do a lot of mileage in the week (I.e none) so I'm looking forward to the 500 miles I need to do at the weekend. I'm praying it uses none and then ill be happy.
I want to start buying bits for it!

I've had my '04 WRX for 6 years now, and covered nearly 70k miles. I've changed the oil religiously every 7.5k, and generally use less than 1 litre between changes.
However I have also found that it will go thousands of miles without using any oil, then use half a litre just like that.
I've also found it seems very sensitive to the position of the car when you check it, so I would suggest checking the oil with the car in exactly the same place every time. On a couple of occasions it has read low, so I've topped it up, then next time I've checked it in a very slightly different position the dipstick has shown it over the top line.
On the subject of which oil to use, I've never gone by clever marketing, pretty packaging, and technical sounding names. I go by the specification on the back of the can only.

This is exactly what I have found. I've decided it's not using any oil it is just really sensitive to position like you say.However I have also found that it will go thousands of miles without using any oil, then use half a litre just like that.

Ill have a shop around for oil. Thanks for the help guys.
For completeness and an update for future searches:
Car went to A specialist who gave the car a look over. They thought it was in good nick. I told them of my consumption concerns. The oil was nearing the bottom of dipstick at the garage. He kept it overnight to check a few bits, all appears ok.
Oil was dropped and replaced with a thicker millers fully synthetic. I've now covered about 900 miles and oil level is still full/just over top mark just after a drive. It seems my scoob likes a slightly thicker oil/ it was running an oil that was too thin.
Hopefully job done.

Topbox. You and I are one and the same my friend!
I've had my 04 wagon for a few months now and noticed a few weeks ago that the dipstick was dry! So panicked and bought some oil to top it up, ended up putting about 2l in which then showed on the dipstick fine.
However a day later after some running the level was really high, so in my panic I had obviously over filled it. I reckon it had around 5l in at this point. Of mixed grades too I expect as I don't know what was in it before but I topped it up with 5w 30.
I've recently done an oil change to fully syn 5w 40 as recommend by Opie Oils after chatting to them. I put in a smidge under 4l and after the change it was showing as halfway on the dipstick. Admittedly this was before running the engine. The next day after driving it home from work, where i did the oil change,I checked the level and the dipstick was dry again!
I knew it wasn't leaking and wouldn't have used 4l of oil on a 3mi journey from work so assumed that the dipstick is just super sensitive! I put in around 500ml and its now reading full. I too have carbon deposits on the tailpipe but it is 9 years old, plus there is no blue smoke when it's spanked so I don't thnk it's using oil excessively.
I will continue to monitor the level but from trawling the forums it seems they are v sensitive to flat ground and weather oil is hot or cold. I have done all of my readings on as flat a ground as possible and 10mins after running.

After getting my 04 Forrester STi I checked the oil - moved the car (from cold) to level surface (3 minutes running), left for couple of minutes, almost nothing on the dipstick - yikes my new Foz is drinking oil the ringlands have gone and I need a new engine!!
Topped up to correct level and drove to collect friend (5 miles) and checked again - well over the full level!
Bloody frustrating, or just get used to to the way it is...??
