Heyyy! The last few weeks i’ve had a new 2023 prius and it’s worked incredibly well. It’s at 700 miles now. The issue is, I live in an insanely hilly area, and I therefore basically can’t follow the break in rules (Sustajned RPM from the hills, etc)
I’m worried this will have a meaningful impact on me later on… is there anything I can even do about this?
Just do the best you can. The break-in period is there to allow the piston rings to seat properly and to allow the metal components in the block to wear In together without creating hot spots in the engine that could lead to uneven wear down the road.
As long as you do the best you can to limit your speed and try to take it easy you’ll be okay.
Do a break-in oil change At about 1,000 miles to get the new engine debris out before it causes damage to the engine. Some people say to do two, at 500 and 1,000 miles, but that’s up to you.
Do you think it would be unwise to do the change at 5k? I plan on doing it every 5k synthetically, and i’d do it at 1k too but my parents would find it unnecessary haha
