Good day.

Noticed the last two days that oil seems to be dropped.

The weather last week is very cold (maximum 6-7C).

Could it drop 1l in two-three days?

Might be because of the cold weather this oil (castrol magnatec) is affected and changes form somehow?

Before was on the blue line,a bit more than maximum.

 

Hi,

All fluids are changing the volume with temperature. In my case i changed the oil in late summer and it was around 27-28 deg Celsius. It was right at the max mark.

Checked again during winter at 5-6 deg Celsius and it was 2-3 mm under the max. I also checked after i drove the car for about 1 hour and the oil was up to temp, typically around 100 deg Celsius in my case, and it was a little above the max. 

So yes, temperature does have an impact, so you should check it at the same temperature each time, or at least as close as possible to the same temperature.

Yes sure, but within two days such difference?

The first day temperature was 8C the next day 4C, so could that change it so much?

Not from the temperature difference of 4 degs.

An I have never seen a car to burn that much oil in 2 days. I've seen cars leaking that much oil though from bad oil filter gaskets, but this would be easy to see when you open the bonnet. Since you opened it to check the oil level, i imagine nothing seemed leaking anywhere?

Mechanic checked it and said nothing seems to be leaking.

Could the temperature since it is very cold make the engine oil particles stuck on the engine's parts (inside)?

Well, there is a lot of oil left, so drive it and check again in 2 days to see if it dropped further?!

I guess there is always some oil in the engine, not everything drops back to the sump. But would less oil drop back when it is cold.... this is a good question, and I don't have an answer.

Exactly that is the question. Perhaps when temperature is that low, there is a significant difference for enfine oil between 8C and 4C.

Checked today.

The engine oil level seems dropped.

Filled 30-40ml and almost reached maximum.

In both pictures the particles near maximum seem to have a gap and while seconds pass they seem to be uniting.

This picture shows oil level four days before, before dropping.

Have you got the car parked in exactly the same place, as the level on the dipstick relies on the car being exactly level. Even a slight slope can give a false reading.

I can't see what you are complaining about. In your first post you say it has dropped 1 litre? According to your picture that is not correct, as it is only just below the full mark. The level from the minimum mark to maximum mark is only a maximum top up of a litre, and that is if you are checking as I say below.

Do you know how the only way to check oil level correctly is? The picture in your first post clearly shows you have not wiped the dipstick and then reinserted it.

Park veh on level ground - leave overnight - remove dipstick in morning and wipe clean - then, reinsert dipstick, remove and check level on dipstick.

Doing the check any other way will not give you an accurate reading, just an approximate one.

Yes.

Yes.

On october it required almost one liter. It was filled a little more than maximum.

Why dont you check the oil level as is recommended, take picture, drive 200 miles (320Kms) and recheck oil lever as per correct procedure again.

Note, oil level should never be above the maximum mark - causes oil leaks/seals to fail etc

You say when you topped it up in October, it wanted nearly a litre - but it didn't because you admit it was then above the maximum mark - why did you overfill it - the maximum mark means what it says maximum - you don't have to keep a veh at maximum, a bit below it is more than ok

After mechanic changed the oil I just noticed that it required a bit more to reach maximum.

I started filling it slowly. One drop - check, one drop - check. But later it reached somehow more than maximum.

Sounds like you didn't allow enough time for it to trickle down to the sump before adding more.

Perhaps although the first two-three times the difference was visible on the dipstick.

Just checked again. The weather is cold but not so cold as yesterday.

Engine oil is fine, as it should be.

Don't worry about the dam temperature - just check the level following the CORRECT procedure

That oil level is ABOVE the MAXIMUM - WHY?

Explained.

Thank you.

3-4 mm above is, alright.

Today.

 

Is that after standing on a level surface overnight, then taking dipstick out in the morning, wiping it dry and then re dipping.

I wouldn't want the level to be ANY higher than that.

Don't forget the oil level does not have to be at maximum all the time, it is quite in order to drive as much as you want with the level at least a quarter of the way down below the full mark

any higher than it is now?

yes.

Ok, so now you need to do weekly correct checks of the oil and, when it shows the level is in the centre of the minimum and maximum marks, tell us how many Kms it has done since todays slightly over the maximum reading 

The engine doesn't burn oil.

But certainly i shall check.

 

Thank you.
