  • How to Break In A New or Rebuilt Engine. This video will explain how to break in a new car engine. It is important to break in a new engine so you get a good piston ring seal and good wear on engine parts when it is first breaking in. This method applies to most cars but there are always exceptions so read your owners manual.

    马英九评党皇帝 (维基百科:纳粹党全称国家社会主义德国工人党。法西斯主义强调民族复兴、国家富强、强人主导国家政治、国家专权集中于一党专政,对内独裁专制,破坏言论自由、新闻自由、司法独立等,缺乏权力制衡。中国共产党本质上就是一个纳粹政党!共产主义、社会主义本质上就是一种法西斯主义!)

    I never once thought of myself getting a new car in the near future. Currently buying a 2019 in 2019 at 21 years old.

    That's why I tote around old cars. Brand new is never a good idea. Anyone can just come up to it in person or with another car and damage it.

    So basically city driving is great for breaking in a new car. I hope I got this right.

    I have found steady state light load good for initial warm up and 1st hour runtime similar to old cam break in at 2300 rpm for 45 minutes lets valve springs heat adapt and bearing surfaces develop contact pattern. Then no high revs above 4000rpm but accelerate to highway speed and slow down to offramp speed for awhile find a hill or steep grade or on ramp off ramp area get up to decent speed and rpm use 2nd and 1st gear on automatics to hold rpm then decelerate accelerate part throttle then decelerate another good ring seater go downhill and use 2nd gear engine compression to decelerate seats rings good remember to change oil and filter after 1st hour and 3-500 miles use. Run up to higher Rpm after 1000 miles. If racing engine run it like it will be driven.

    I have a 2017 SHO, its getting a brand new engine cause my had a defect from factory and failed at 7000km, however it has paddles to select gears, should i used those when breaking in the engine? Keep it at a high rev for a bit, then upshift keep it low, then somewhere in between, repeat, or would that. Cause an issue?

    I drove my brandnew car with 120kms per hour. Is that ok? I mean its my first car and got it from another town and its kinda far from where I live so I had to at least run it a little fast. If I did it wrong, is there any chances that I could just do the right thing over? Or maybe its just too late? Thanks man!

    Do the same rules apply for freshly rebuilt engines?

    I have a 2005 Mazda 6, and at 200,000 km i had to replace cylinder sleeves, pistons and piston rings. Do i drive as you said here, or are there any other nuances?

    Start the car and put the pedal to the floor for the first 500-1000 miles depending on the manufacturer's specifications. After that don't change the oil, and drive it normally. Lol

    You don’t need to break-in a new Ford. It will break down for you automatically. What’s the point. It’s not gonna last. Just turn on, drive away and floor the gas pedal.
