Default Forged piston
Hi guys, I've got a Wrx hatchback and it got rebuilt in September last year with forged pistons. Done 3500 miles since and it's used 5L of oil, been back to the builder and they said that's normal for forged pistons. Is that too much and if so hows it using that much?

0.5 per 1000 could be normal, 1l seems a lot but 5l over 3500
Mine forged 2.1l took maybe 0.2l over 1k miles

how was it 'run-in' on what oil and what oil do you use now??
what use does the car get in terms of normal road or track style??

Who build the engine?

Any smoke out the back?

A million reasons good and bad why an engine uses oil. Stockcar scratched the surface above.
