Is my oil usage excessive?

Is my oil usage excessive?
My 2003 WRX PPP seems, to me, to be using a lot of oil. I had to top it up a litre around 2500 miles ago. Today I have topped it up another litre.
There's no smoke, there's no smell, the car sounds and drives normal etc. and the power seems to all be there. A search on here brings back lots of guff but I have managed to find people saying it's normal to use oil and people saying it's not, so I'm no happier.
What does everyone think? Car is on 102k now.

At 40,000 miles my 03 WRX used a litre per month, at 80,000 it now uses a litre per year.
I don't have an answer for it. I use stop smoke for MOT's but I thought that was a cure for a matter of days.

If your 2ltr consumes that much oil, something isn't right. The Newage 2ltrs shouldn't use any oil as an OEM build.
Get a leakdown test done.

I guess it varies slightly car to car, I cover around 120 miles a week to/from work mainly with the odd trip at the weekend. Never tracked mine and probably never will but have the odd bit of fun and literally checked my oil this morning and apart from being a bit darker hasnt changed level whereas some other owners are reporting high oil useage without any faults so I probably wouldnt worry too much and if you are have tests done to put your mind to rest

Whilst it seems heavy, it is not excessive. BMW for example say anything up to 1ltr per 500 miles is acceptable! As you have done, if you are concerned go for a leak down test.
What oil is currently being used? And does the car see any track use or is it just road fun?

Off the top of my head, I think I am running fully synth 5w-40 at the moment.
Tyler, the leak down test and compression test are two separate tests as I understand it. Compression test will give you a PSI value for the compression of each cylinder, leak down test will give a percentage value which I *think* (as I haven't looked intot his before now) indicates how much pressure loss occurs in each cylinder. I'm sure someone will correct me shortly.

I'm running fully synth.
Actually it needs completely draining and replacing with new so I might get some from Opie. I was in a bind and bought Triple QX stuff from ECP. I've not had the car massively long so having topped up with that, it is actually very possible it was running a different grade already.
Sadly, after I first discovered the issue and topped it up, I had bought a new oil filter and planned to do the full change and it ended up completely slipping my mind.
Guy, what would you recommend for me to buy today? 102k miles, PPP installed. If leakdown test is OK I plan to take it to 300 - 320bhp.

I would go for a 5w-40, but using a different one can reduce oil consumption as that can vary from car to car, oil to oil. If it was a basic oil in there, it could burn off quickly.

Out of those, the best ones are the Fuchs/Silkolene Pro S, Millers CFS/CFS NT, Motul 300V, Red Line and Gulf Competition. The Motul 8100 X-Cess, Millers XF Longlife, Fuchs GT1 XTL/Supersyn, Gulf Formula G, Shell Helix and Mobil Super 3000 are good, cheaper alternatives.
