Oil Abit Over Full

[BLKek]

Does oil expand under hot temperatures (I know it changes density), or has it been developed not to?

I'd always check when cold, its what my grandfather taught me, he used to build hot rods so I trust him...

It does expand a bit. Accord to my father (diploma in automotive mechanics), whether you check it when cold or after it has drained for 5 minutes, they are roughly the same because of the oil expanding when hot and contracting when cold. But he does say that he waits for 2-5 minutes.

The best way to check oil level is in the your car manual. Spend some time reading manual. It has so many good tips. eg. when to shift for good fuel economy. If you don't have it, borrow from someone else...

Ah, okok. But will the splash guard protect against overfilling?

...

depends on how over full it is

there is a limit to how overfull you can go before oil in the sump will sit to high when the engine is running.

I dont know what that limit is.

I religiuosly set the oil to the top dot after servicing a car and recheck it after road testing.


seems to work ok.

i seem to be having a prob getting the setting of oil right also, my posts on the Tech side but my problem seems to be coming from an oil cooler install.

ECU-MAN can you comment on my thread also plz

Ahh, ok. Good too know that my dealer overfilling by that little bit won't do damage. Thanks ECU-MAN!

guys sorry to burst the bubble but i did some goggling cos i got confused. At the Clubrsx site they told me i was supose to check the oil whilst the car was settled for a while so i did a search.
All these sites tell me to check after a while or even in the morning which is overkill i think.

Have a read!

alright now i've done something that i haven't done for along time. I had a look in the car manual. Honda say to wait a few minutes after turning your car off before you checking your engine level

P.S Arronng You were right, you deserve some Rep for that, and i'll give myself a pat on the back for not just going with the flow.

Apparently the measure of the oil is how much is in the crank, so you need to let the oil settle back to the crank area. Thus give it about 5mins.

I've gone and taken the oil out for the 4th time now. After about 5mins its just on full. On hot take its about 2-3mm below the max line.
I think that should make the car less sluggish.
