Oil use Mobil 1 (0 - W40) and compression is 10 to 12 bar. 12 bar is V Good.

12.4 bar cold engine and 10 bar hot.i think i am ok.but i am worried because spark plugs have some oil.

Maybe stuck oil rings allowing oil to pass. Put a teaspoon of transmission fluid into each of the affected cylinders then put the spark plugs back in an run the engine until hot. Do this outside as you will get a lot of smoke from the exhaust, this should free the rings and things will come back to normal.

To keep the engine running during this process you will need to keep the revs up to, at least, 2k rpm.

i will try eric.i am afraid because i dont change the engine oil for 2 years because i dont have many km.i will change next week.i think 10-40 for greece is ok.

Sounds like the car is not used much so the transmission fluid trick may work. But use Mobil 15 - W40 for the oil and filter change.

full synthetic?semi? or what?

They only do one type, simply buy Mobil 1 (15-W40).

my other problem is.......i have fault at my ecu ram.i delete but....again fault.when i stay in the car with P or N i feel the engine to move the car left and right strange......like to dont work good one or more cylinders.before 5 days i change spark plugs,clean injectors and throtle body because was so dirty.maybe from the ecu i have all symptoms like spark plug oil and strange move?

I do not fully understand what you are saying, perhaps english is not your first language? Have you had the fault codes read out using diagnostic equipment?

im sorry eric but im greek.we reflash the ecu chip back to original stock but i have fault code at my ram.

What is the fault code?

 

[g(sl500)]

really i dont remember the code. before i tell u that i feel the engine move strange like one or more cylinders dont work good.i make compression test and is ok.i change sparks,clean injectors and throtle body.maybe all symptoms have to do with ecu fault?

Without the fault code this is a waste of time.

File,
Please give the year of your car, etc, so we know what you have.
You will get more help this way.

By the way we have a few Greek members.
Did I mention that most members know that I speak Greek. Lol.

Oil 10W40 is fine, two years between changes, is way to long.
Remember oil is cheap, aluminum engine is NOT.

Welcome to the forum.
