Hey guys finally got around to changing my oil, but the oils is black and smells of petrol is this normal?. Thanks

Hi, a few question so we can maybe help...

- when had previous oil change been done ?
- was the oil quantity ok or too much ?
- how many miles is the engine ?

Regards, Bernie

It's pretty normal in some circumstances:
- long oil change intervals;
- short trips, the engine runs on a richer mixture when cold;
- thermostat stuck open.

Cheers for the reply guys,

last oil change without filter even though I was told it had was a year ago. It has done 94k and I do a lot of short trips, but it takes a while to warm up say 10mins.

Hmmm, short trips, engine not warming-up, seems like Aurick already had the answer...

When the engine is cold, the ECU asks for a richer mixture, that will partly deposit on the cold engine surfaces: intake ports in cylinder head and cylinder itself. The final result being a mixture at (or close to) stochïometric ratio.
Side effect is that the petrol deposit partly washes the oil on the cylinder wall and finally drops in the crankshaft housing, giving that petrol smel to the oil but also altering its lubricating properties...
Regarding the thermostat, is the T° stable once the engine is warm ?

Regards, Bernie

ps: Curious to know you fuel consumption ?

You should get into the habit of regular oil & filter changes. Possibly the easiest & best thing that just about any one can do. I echo the short trip type driving. One last thing, don't get hung up about "best" brand oil, use the spec for your engine. Regular changes....remember..

Yeah it's stable once warmed up, consumption is 39.5 average.

Hi,

consumption doesn't seem too bad to me, ca 40mpg (bit more than 7.2l/100km) doing short trips is quite reasonable.
Stable T° indicates the thermostat is working properly; have you ever thought about limiting the air intake to the radiator ?
A carton board and few tie-raps would do the job perfect, I'm pretty sure Aurick does that in cold Bucharest...

Just remember to NOT cover the turbo intercooler area (the lowest grid) nor the fan area (passenger side for UK) !!

It doesn't have a turbo but what do you mean shorten the airflow.

Wasn't meaning to restrict the airflow to the engine but to the radiator in order to allow faster heat-up of the engine... (only in cold weather !!)
