    Thank you! I am just about to get my first brand new engine, it's exciting but I know you have to take special precautions to prolong longevity of a new engine

    Hey Cris thanks for you knowledge!

    Question. Manual doesn’t say and dealer says that I need to first service at 500 miles. In a new car, is it true the first service needs to be done at just 500 miles? If not how long can the first new oil from manufacture last?

    This seems excessive but it’s simpler than it sounds

    new engines so sensitive you have to break them in properly no wonder why the engines break so fast

    Even new cars have 50ish miles from people test driving them. I hope they weren't too rough.

    Hey Chris I know this is an older video but does this also apply to reman engines I just got a new 4.6 2v put in after my car seized and I’ve been really paranoid about it

    That new car engine was already broken in before it left the factory.

    The OEM “break in recommendation is a fail safe in case the rings didn’t get seated 100% during the factory break in.

    In the quest to adhere to and surpass fuel economy standards, nearly all new vehicles Today are designed with extremely thin piston rings. Thinner rings seat almost immediately under load.

    “Tire break in” that’s a new one!! That’s 100% to reduce service appointments for road noises and ride complaints.

    I came here because i wanted to share my experience with a used 2018 subaru impreza hatchback. 2.0i limited.i got it for the awd for snow. I didnt love the lack of power only 152hp. I do routine maintenance and after the factory maintanance package c the car felt different. Felt faster off the line. This was after 60,000 km now i love it. Is this from the tune up or me getting used to it? Bought it at 39,000km no recordsof maintenance from previous owner. Gonna do spark plugs and transmission fluid change next.

    My biggest fear is that my used car hasn’t been broken in and because of that it won’t last

  15. Avataaar/Circle Created with python_avatars Illuminate me says:

    I know I know.. it’s old but I MUST address this. Those automatics actually use a dual clutch transaxle.. so.. there is a clutch (two of them) and you can manually shift through the gears. It’s like two manual transmissions combined into one unit. Remember the shudder problem in these?
