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

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....

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?

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)

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 ?

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

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.

I can just tell, threads gonna be about which oil is better. haha, my 2 cents....i use magnatec 10w30 and couldn't be happier...cus it's free!

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

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

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!

      This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
