oil levels.

[09FD1]

hey all,

i dont know if its just me but today i have noticed when checking oil levels while the engine is cold that the levels are lower then when the engine is up to temp, so i was wondering which one is my actual oil level at? while its cold or up to temp?

cheers guys!

Check when cold.

oh okay. strange because i just got a service done not long ago and my transmission oil is down quite a bit already :S

thanks for ur help :)

Are you talking about engine oil or transmission oil? They are both totally different things and have to be checked at different temperatures.

[09FD1]

never mind. just had a quick read of the car manual and found the answer there.

thanks anyway :)

What's the answer then?

I always just checked,like,wheneva! :)

My tranny oil was low,after I did a change,hence why the auto was changing gears too early I think cause I topped it up and it's back to normal.

Does that sound right Aaron?

(I put too much in,then I took too much out lol,the damn thing only holds 1.9L!!)

for transmission oil check when engine is running temp. i use to check whenever too LOL. noticed it happens with coolant too, much more coolant in the reserve when engine is running temp compare to when its cold.

[beeza]

So:

Coolant = running temp
Trans fluid = running temp
Engine Oil = ?

Cheers mate.

oil level can't be higher after a drive...maybe you aren't reading the dipstick properly.
anyway check in the morning and you can see the oil level clearly.

[09FD1]

im quite sure it was lower this morning b4 taking the car out then it was in the afternoon when i got home. and in the civic manual it states that to check tranny fluid while engine is at running temp =S. i shall check again tmr morning before i head off to work.

@beeza
not sure for engine oil.. today when i checked both times, cold and running temp, it was on the same level on the dipstick.

aaronng, engine oil check at what temp?

[beeza]

Cheers mate!

[09FD1]

as stated in civic manual "make sure the engine is warmed up and the vehicle is parked on level ground. turn off the engine and wait approx 3 minutes before checking the oil level"

so engine oil = running temp.

[09FD1]

no problemo :)

[beeza]

hehe :)

So that's all 3 at running temp then.

I'll do that tomorrow!

[aaronng]

When cold, the oil is a smaller volume, but all of it is in the sump.
When hot, the oil is expanded to a larger volume, and part of it is in the valvetrain.

So in the end, it will be similar. :)

[beeza]

hahaha,classic!

Thanks for clearing that up Aaron :)

I know where the level were today on a cold engine,I will check when running temp. 2mozza!

[beeza]

Cold the tranny fluid read full,after being warmed up,it read 1/2 full.

[09FD1]

LOL

mine is opposite :S

oh well, as long as theres stil some in there and its not running dry.

[beeza]

haha,far out!

I will double check it over the weekend lol!
