how long for the engine to losen up

[zippyy]

see title

 

[Fred@BTM]

depends on the engine and how its driven

on a 172, the going rate is 20K untilthey come alive

thrash the crap out of it, best way to loosen it up

 

[Sport182]

My 172 got quicker and quicker as it went on the 182 seems to be doing the same 2.5k now and its much better then at 1k

 

[Ben H]

Ahhhh... have arrived at 21k miles on my 172!!!

 

[BenR]

deffo have to thrash it

 

[Little Newms]

Mine was quick when i got it on 12500 miles, but 5000 thrashed miles later is soo much better!

 

[Neil82]

Well mines been beasted from 500 miles and oil changes every 5 k and now sitting at 19400 miles and it fooking flies!

 

[rory182]

mine flys at 17000 and approaching its third oil change

 

[nixontim]

So how do we break them in? Thrash from day 1 or is there some preferrred technique to follow?

 

[peterh2]

Get it warm then give it death... worked fine for me. You have a warranty if it doesnt.

 

[zippyy]

What about the running in period?

 

[Big G]

Drive it like you stole it .

My Cup was going like a rocket from about 3.5k miles and ran the 1/4 in 14.5secs at that mileage, it got a little better after that but was basically run in from about 6k.

20k is too long unless you never thrash it.

I ran mine in gently as per the Renault recommendations (read the handbook) then gradually built it up and did its first 1/4 mile run at ~1250 miles

Always let them warm up fully first, but you can drive them hard and they lap it up.

 

[blink172]

650 miles of varied driving from new. Some hard workouts and some motorway stuff.

After that, once its warm give it hell!

 

[tango82]

hell from day 1. it has a warrenty and unless your going to keep it for more than 3 years who cares. as the boys said DRIVE IT LIKE YOU STOLE IT, lol

yeah but you had a special "northern" cup, so it was always gonna be faster from day 1

seriously though, the quickest clio ive driven has 75000miles on it (52 plate!!!), all the others ive driven still feel tight

 

[Fred@BTM]

high load, low rpm, best method for runing in

do that for 300miles, then weld the right pedal to the floor

Some cars do take a loooong time to run in though, my mates mk1 172 was pretty lame until it had about 50k miles on the clock then all of a sudden it was a rocket ship!?

He sold it a few months ago with over 100k on the clock and it was a flying machine...

i think 20 k it opened up and then again at 30k mine was going.

At 75k it is rapid as you would expect.
