    forged pistons?

    hi guys, i bought my car stock about a year ago only had a tbe 3" ever since i bought it, i burn oil realy quick, i know turbo cars burn abit of oil wich is normal but my oil finishes (after a service) 200 km i would look on the dipstick and there would be only a dip of oil left, no i dont have any blue smoke ( only under hard acceleration but very faint), turbo has been changed didnt fix the problem( got a brand new turbo td05) , no leaks checked rocker cover gaskets, sump, sump plug, rear main, chrankshaft seal, turbo return line, theres no leaks at all,valve stem seals dont seem to be blowing smoke? compression is good around 150 @ each piston wich leaves me to my last conclusion, forged pistons i heard they burn alot of oil this true? i think the previous owner had abit of work done to the car due to finding cut boost lines in the cabin, underneath engine covers missing (possability of front mount)
    so bassicly is there anyways of seeing if internals are stock? without ripping it apart lol or could there be another explaination of my oil problem i use to use
    fully synthetic 5 w-30 royal purple, now i use fully synthetic 10 - 30w penrite, should i use something thicker?

    You could use a bore scope to look at the piston tops. I would change the oil to a 5w-40 or 10w-40.
