Engine Oil... Excactly How Much Do I Need To Put In?

[br3ndan]

hey guys,

I was just wondering exactly how much engine oil do i need to put in my skyline. I have a RB25DET R33 using Ryco z145a filters... Does anyone know exact amount i need??

Cheers

Engine manual recommends 4.4L if you change the filter with the oil

[br3ndan]

If the filter is bigger then the stock one would that make a difference?

[Bliksem]

Ofcourse... Just buy 5L of oil and a new filter and measure how much you use. From then on you'll know exactly how much is required...

[NA_Goodness]

Doesnt really matter, buy a 5L container of oil, put half of it in, run the engine for 10 secs, the check the oil. Once that is done, keep topping it up until it is on the full mark. Depends on how much oil is already in the engine as to how much it will accept. But roughly 4.4L would be the norm

[br3ndan]

THe problem is i filled it up and it was sitting a bit above the 3/4 mark. And itts been like that for awhile now. When i checked it today its gone over the full mark?

Any reason for this? THe oil is just under 5000kms old.

I put little bit less then 5 litres in. And at that time and other times it showed a bit over 3/4. And i did check it when the engine was hot.

Im using mobil 1 5w-50w....

[br3ndan]

Im pretty sure i put to much but i did start it up let the oil move to the filter and again top up... and it said 3/4 on the dip stick.

Maybe its the mobil 1 oil? to thin when i put it in?

[Bliksem]

Did you let the motor sit to let the oil settle back down to the normal level?

Also Ideally you'd probably want to run something closer to what Nissan recommends such as a 5W 30 instead of the thicker 5W 50 (the last number is the viscosity rating when hot, lower number = thinner)

[br3ndan]

What oil are you using? ..

I think i will change mine, but i got one more bottle left of mobil 1.. 5w - 50 w.

So ill use it up.

What do u mean let it settle down? After ive changed the oil or just normal checking of the oil ?

[Bliksem]

When you do an oil change you have to let it flow to the sump before you check the oil level. Same goes after the motor has been running. If you check it straight after switching the motor off it will be an innacurrate reading as the oil is still flowing back down to the sump from the head etc, so let it settle for a good 15 mins or so in those situations.

I use Royal Purple 5W 30, Nissan Recommends 7.5W 30

[br3ndan]

where do you get this royal purple oil from? Maybe i might give it a go...

Or maybe the mobil 1 0 - 40...

each to there own. Ive been running 5w50 mobile 1 in a car that does track work for over a year now and couldn't be happier.

as for oil amount. if your changing filter then as already stated its just shy of 4.5L. if your going to be doing track stuff then maybe chuck in about 500ml more.

Cheers mate. THanks for the info

http://www.royalpurple.com.au/ It's available online from Hi Octane, and also from ebay.

nah we don't need to do that there are plently like them already

so if you ignore my "branding" earlier here is what i think is rough guide. Only get a fully synthetic, make sure the cold weight is between 5-10 so it gets things like the turbo lubed up nice and quick, and the hot weight really can vary from 30-50. I kind of go the thicker hot weight because these are old engines. my clock says 80,000 so in truth its prolly way over 100k so the internals are no doubt far from looking like they did 12 years ago. oh and finally make sure this happens every 5000km. Then everything in life will be just peachy

also have you read the goods on oils sticky? think you might find it most helpful.

cheers

Correct moobaque. I use oil with a viscosity rating of 30 but my motor is new... The only time it is not advisable to use a Synthetic oil is during the run in period...

[br3ndan]

All done.

Took approx 4.5 litres. Mint R33 you were correct, last time when i filled it up i didnt wait for the oil to come down back into the sump. This time i did and its all good!

I ended up using mobil 1 5w-50w since i had one more bottle left. But i might start thinking about other oil at a later date. i.e closer to the next 5000k oil change.

Haha.. yeah about the goods on oil... its just a massively long topic about which oil everyone thinks is better. I was kinda after the oil capcity rather then what oil to use .

Thanks for all your help! Appreciated!

[Bliksem]

Good to hear your all sorted out mate
