Using oil with 3000 miles on rebuild

Hi
I'm just coming up on 3000 miles on the engine I rebuilt, and the car is still using about 1 litre per 1000 miles. I do not notice any blue smoke from the car, and it starts flawlessley even without glow plugs.
The pistons are 0.5mm OS Kolbenshmidt with supplied rings. I think the rings are the newer chrome based material and am wondering if this is the reason for high oil use. I'm running a 10w40 oil but topping up with 15w40 at the moment.
The turbo is a fully rebuilt exchange unit from a very well know turbo company here in the UK so I am not blaming that at this moment.
I realise its very hard to pin point the cause for oil use, but just wondered if others have had this experience with rebuilds?
Thanks

Did you baby it during break-in? Did you use synthetic oil?

No, the car has been driven normally, which has been mostly highway, but I made sure to load the engine often.
The engine was filled with no name 15w40 mineral for the first 50 miles, then changed to 15w40 Shell Rimula R3X for 1000 miles. It is now running 10w40 Fuchs Titan XTR semi synthetic, but topped up with Total 5000 15w40 mineral

Should be running dino 10w-30 diesel rated. Mostly highway is the worst way to break them in. Continual varrying RPMs with load is the best.
Do not use sythetic/blend until your oil burning stops...it may never stop now.

Probably never got broken in all the way and is just using oil because of that. Pull what you have and go back to the basic oil you started with. Save what you have if it is just been put in there.

Ok, would using any sort of running in oil help or should I stick to the real cheapo 15w40 mineral and drive it really hard. Im a bit scared to run a 30 weight oil.
I have seen this stuff but again this looks pretty severe on the engine:

Rotella T3 10w-30 it is diesel rated...New CAT engines are required to have it in there. My build had 10,000 miles on it to start before I switched to syth...as long as you didn't skimp on bearings, oil pump, ETC your engine will be just fine.
No experience with the liquid glaze bust.

We've been running Rotella 10w30 for our break-in. No real consumption as far as I'm aware...but we have a leak from our turbo drain line so its hard to know where the oil is going

We don't seem to have 10w30 diesel oils readily available in the UK, they might be sold in farm machinery shops though. It is mostly 40 weight oils for everything before 2000 and 30 weight oils for newer cars on long distance intervals.
I can get cheap 10w40 or 15w40 mineral oils with basic acea specs of a2, b2. No synthetic content, would these be suitable.
I obviously wrongly assumed break-in would take 1000 miles or so.
Is there any benefit to driving the car fairly hard when it is cold? Up until now I have been easy on it until the temperature comes up, then I drive it fairly hard.
The engine really seems to have loosened up in the last 1000 miles, is very responsive and starts 100x better than it did before rebuild.

You want to be gentle until it is up to normal operating temp. Then you want to do bursts of power, not extended full pedal runs. Like 3 seconds full pedal, 5 seconds no pedal, etc... The rings need the pressure of load to push them against the cylinder walls and then they need time off to cool.

Ok, so yesterday I took the car out. I haven't been able to change the oil yet, but I stuck it in 3rd and was doing good bursts of WOT from 3000rpm, up to about 4200rpm, gently coming off the throttle and letting it over run back down to 3000rpm then going back up to WOT etc.
The engine is really keen to pull, even to 4500rpm.
Am I doing this correctly? When I get some crappy 15w40 I will continue this

Does anyone think I should this Glaze Buster oil? It comes from a reputable lubricants company here in the UK, but SAE20 just seems to thin to run in one of these, even for a short period of time. Am I wrong? Or should I stick to the crappy 15w40 and thrash it

Shell oil. Rotella T-3 10w-30 isn't available? It is in every store that sells oil in my area of the USA. If not I would run the 15w-40 that is diesel rated. I wouldn't thrash it either, just keep it loaded all the time like Libby diesel said.
