Oil gets black pretty fast, especially if its a lower quality I noticed.
Was the oil real thick as well, or have any white in it? Have you tried a bottle of octane boost? If there is water in the fuel that normally helps burn it out faster.

Where do I get octane boost and yea it is thick like thick enough not to drip off the dip stick would a bad batch of fuel last so long I let it run almost drina few times now and filled back up with 98 oct and I've done that probably 3or 4 times and dose any 1 no how much it is to do the spark plugs on my motor it's the 190 if it helps
When the air is colder at night, it might make the car 'feel' quicker compared to the day time. It can make the car feel different
Not a dirty air filter? you might need your spark plugs changed too

Thick black oil is a bad sign and usually means a sludged engine.
Take out the oil filter and see if its caked in thick sludge.

Do I have to drop the oil first to take the filter out ??

You should be able to take the filter out without dropping the oil, but if its thick it may be worth dropping anyway

No you dont have to drop the oil to check the filter mate.
Lets us know what it looks like and we'll see what to do next.

Personally, i think its due for new plugs
Plus a good oil cleanout

I haven't had the chance to have a look at filter if I drain the oil will it get "sludge" out of the engine or is there a way to flush it out and should I drain it cold or warm ?? I'm new to this thx for the help

Depends how bad the sludge is.
If its really bad get the engine hot and drain all the oil out.
Fill with cheap oil and a couple of bottles of engine flush and idle for about 30 mins.
Drain oil and refill with good oil and fit a new filter.
There is a risk that the engine flush will cause the dislodged sludge to block the oil pickup and cause oil starvation but this hasnt happened to me yet and Ive done a few. Just stay with the car the whole time and if it starts to rattle or knock shut it down straight away.

How would I fix it if it dose cause oil starvation and what sort of oil do u recommend to put in its done 130k and do i have to use the same type of oil to flush and to fill it it for example flush it with 10 30 and fill it with 10 30
And do I fill it with cheap oil till it shows as full then add bottle of engine flush or do I mix them and then fill it
Dose any1 here live in Melbourne

If it did block the pickup the sump would need to be removed and the pickup and clean it all out.
Just use cheap shit oil to flush anything close to 10/30 is fine, make sure the engine is hot then put a couple of bottles of flush in then add oil till on the full mark.
Then let it completely drain let it sit for half hour draining then put good oil in.
After that change the oil and filter every 5000kms.
No guarantees but its cheaper than a new engine or complete rebuild.

Yea it sounds cheaper I'm gonna give ita shot onfriday and do the plugs has any1 here done them before is it a big job

Just gotta undo the intake manifold bolts so you can lift it up enough to get access to some of the coilpacks/plugs. Dont have to actually remove it.
Just dont undo to front right and rear left bolt because if you do the manifold will seperate and may tear the gasket. The right rear bolt is a bastard to get to as well.

Ok so I drained the oil to day it was black like soy sauce but wasn't as thick as I thought but black as he'll the oil filter was filthy and I dnt believe it had been changed also put a k&n filter in it and it's running a lot better spark plugs early next week
