How often should i change the oil in my car after a new engine has been installed?

i had a new engine installed about 4 months ago, and had the oil changed after the first 1000km. is it every 10,000 km or should it be sooner/later? or possibly every 4 months? thanks for your input.How often should i change the oil in my car after a new engine has been installed?
it should be every 3 to 5 thousand miles...depending on the type of driving you do but not more that 5 thousand miles.


after 5 thousand miles the viscosity ( i think i spelled that wrong) of your oil is so broken down it is doing little to protect and lubricate your engine.





*edit*


on a side note here...if you put a knew or even a rebuilt engine in your car be careful....you don't want to push that engine to hard for the first 500 or so miles....500 miles is your average break in point....i like to put about a 1000 on mine before i make it do any hard work but then again i am a little over cautious.How often should i change the oil in my car after a new engine has been installed?
Change both the oil and the filter every 5000 miles.
Every 3 months or 3,000 miles.
Newer engines these days, like the one in my Toyota Tacoma, requires an oil change after 5,000 miles instead of the standard 3,000 miles/3 months. Check with your mechanic to be sure.
3,000 for regular oil





5,000 for synthetic oil
depending on how many miles are on the engine, 3 months or 3000 miles but if the car has an extremely large amount of miles on it you might want to do it more frequently especially if it is driven mostly on residential roads rather than highways driven
you can go wrong with 3months or 3000 miles. it has to be a decent engine to be installed in your car in the first place, well at least better than the one u had.
I'd do it every 3 months no matter what the miles are, to keep the engine running smoothly.
3 months
every 3 months or so
ther same as every thing else every 3 months
Probably more often then you changed it on the last engine.
Depends on the type engine you have. Ask the company who installed it, but generally we're told every 4000 or so miles.
every 3 months or 3,000 miles
dont worry about changing it they will put new oil in each time motor is replaced
Every 3,000-5,000 miles.
