how to do run-in for new car?

Glen999 SG

i'm collecting new VIOS this weekend.

Is it necessary to do run-in for a new car?

carmour SG

I dunnoe if this is true, but a Subaru SE told me that new cars do not need to “run-in” anymore as “run-in” is only for cars of the past.

That's my understanding too..........but I am really a novice (knowledge of cars). Hopefully, you will get better responses. Wink

just dun ram ur accelerator or brake too hard…. better to put that off until the first servicing… 1000km…

go to vios forum and ask loh

Recommended run-in for Vios:

Don't go beyond 3K rpm and keep ur speed below 80kmh. After ur 1K servicing, its showtime. Very Happy

it is stated in yr car manual. go take a look. Very Happy

In Vios forum, there is a whole extensive steps to properly run-in the Vios. I heard have to rpm certain rpm for certain amount of time then cool engine......

Better to go ask the Vios guys.

Not really lah. I'm from there too. Smile

Just have to make sure that u don't rev beyond 3K rpm until ur 1K servicing is done. U wouldn't want those metal residues in the pipes to rush through ur engine before they change the mineral oil. Twisted Evil

I think for new cars, you will still need to run in...

This is because the engine block in a new car is still not "seasoned" and furthermore, the walls in the cylinders are not lubricated enough...so if you just don't care about it and rev your new engine, it will not be good for the engine... friction etc...

It might not be obvious initially, but I've read before that in the long run, the engine will deteriorate faster.. so if you are kind to your engine in its early (infant) stage, it'll last longer...

If I'm not wrong, running in for different cars varies...some cars require up to 3000km before you can rev your engine above 3000rpm... you have to check with the mechanics when you go servicing...

Sorry folks, something was wrong with my Internet Explorer, that's why there is this repost.

I got the info from a friend who got his car last dec. It looks to mine to be some eleborate series of steps someone came up specially for Vios. Don't know if it is from the Vios forum.

Larry SG

Guess the whole idea is not to rev ur engine. Laughing

Best is to keep your speed below 80km/h ... No high revving , no speeding and of cos at that speed ... no overtaking on expressway ... Wink

wow…tats something new i learn…

Glen999 SG

hi, just found out from expert.

just drive normally. over 80km/h etc.. it's fine as long as 3 restrictions are adhered to:

1) don't 'cheong'.
2) don't do emergency brake
3) don't maintain the same speed for a long time.

Mogu SG

Running in is advisable for new engines. This is becos new engines exist particles from the walls and since first servicing is at 1000km, the particles will remain in the engine oil until u flush it.

Ramming the car will cos the engine oil to splash harder, cosing wear and tear to the pistons.

All u need is not to rav more than 3ooorev/min.

Glen999 SG

i asked the same questions. this is not true.

normally, factory already does some QC and revv your engline liao.. therefore, your car engine is not a new one theoritically.

mydear SG

Very Happy loot n loot n loot can liao Mr. Green

wbucket SG

They don't revv it long enough to achieve the desired effect from the recommendation of the Manuals. Since there is no way to know how long, or how fast the so-called QC revv the engine, I guess it would be safer to run-in yourself.
