Yes what Sheriff Wan said.

If you check it after the car has been driven / warmed up, the oil level will not be accurate.

Check it first thing in the morning is the best, so a cold engine.

^Yes thats right.

The oil must settle 1st.

If you read the oil dip stick while the engine is running, oil pressure will build up and again, oil will be all over the dip stick and you wont get s correct reading.

I agree with the guys, And I recommend oil to be checked first thing in the morning as the car hasn't been started for many hours. I even recommend that for changing oil so that all the oil is down the bottom. If gota do it after u been drinving the car than u must stop the car for at least 2 hours, or more if possible.

I don't agree.

hot dip it within 20 minutes of stopping the engine.

Remember that oil is viscous, therefore it 'expands' and 'contracts' under different temperatures - so it's probably ideal to check your oil when it's warm to simulate oil level when the engine is actually running.

So do I (disagree)!

You can check the oil level any time you like, as long as the engine isn't running, and the car is on level ground. If the engine has been running, leave it for as little as a minute before checking. After all, it's only a rough indication of oil quantity - it's either visible on the dipstick, or it's not. If it's visible, it's either high or it's low.

And always run the engine for a few minutes before changing the oil - the oil flows out much easier when it's warm.

Definitely doesn't take 2 hours for all your oil to drip/seep back to sump. 15-20 minutes if car has been driven and then when you've pulled the sump plug leave it out whilst you change filter and clean up, even go make yourself a coffee. I normally leave plug out for 20 minutes or more.

the skyline manual I have says to check the oil when the engine is at operating temperature and has been off for a few minutes.

for best results make sure the car is on level ground, pull the dipstick out and wipe it, then dip it again to check the level

I drop my oil when it is at operating temperature and let it drain for about 20 minutes to get as much of the old oil out.

just have to be quick moving your hand out of the way when undoing the sump plug, because naturally, hot oil burns like a bastard lol

Yeah you probably right, I just like being on the safe side, n wait a bit longer to let all the oil go down.

i always used an open spanner after undoing the sump plug with a socket.

takes a while for the hot oil to start dripping but when it does use the spanner and let it drop into the oil so you dont get 2nd degree oil burns.

make your tea as stated earlier then pour the oil into an old oil jug (remember you are not meant to bin it - recycle man) and grab the plug out or your drip tray when you can see it, wipe it with a rag and bung it back in there.

used to be able to cope tith hot oil but now i have girly office hands it burns like a bitch.

i also believe that oil levels should be checked at cold as this allows the oil to settle, and when adding oil you are not heating it up to operating temp before adding it. therefore factors such as heat and the expansion or retraction of oil variables are reduced. dip stick markings in my opinion would indicate the absolute reading at the period where conditions are least subject to variables such as oil in the motor and temp - ie ambient temp after the greatest portion of the oil has dropped to the sump.

my 2c :(

i cant believe it had to be asked, but spose better than not asking.

might i also add dean you should check it regularly. I check mine when i wash her usually as habit, along with coolant levels, washer bottle, power steer and glance over brake fluid etc. Its always better to check it before problems develop, coz its usually one of your first signs somethings going wrong.

Other than an automatic transmission and power steer almost every fluid on your car is DESIGNED to be checked cold. The dipstick is not designed to allow for heat expansion as its a poofteenth effect. WHY cold and after sitting for a while? Coz its a true reading as almost all the oil has dropped back to the engines sump.

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
