I'm looking at different oils to use for my car,

need some recommendations, I'm looking at this one NULON

http://www.nulon.com.au/products/Full_Synt...sel_Engine_Oil/

thoughts?

Cheers

had my car car on the dyno the other day had to change my oil before it went on. the dude that did it told me that castrol gtx 530 is the best for em.

I have tried a multitude of oils in mine, although I only stick to grade 4 and 5 oils. I have found for the m35 a 10w40 is perfect, anything thinner and it runs a bit noisy and thicker it doesnt seem to rev as easy.

The VQ burns a bit of oil at cold start but it isnt past the rings or valve seals, it is the pcv breather on the plenum. It dribbles out of the pipe down the middle two runners and onto the valves just waiting for you to start the engine. It can be stopped by installing a pressurised catch can but then you will need to empty it of water and oil monthly.

I don't know why you get water in your catch can Scott. I certainly get some oil but never any water....

It used to be water, condensate out of the oil from the cold Melbourne winters, now I get ethanol evaporating out of the oil also.

Are you running the stock thermostat? I had to go back to it as the water and ethanol wouldnt evap at the low temps...

I have the Nismo thermostat fitted on my car.

There you go, water wont evaporate very well at those temps, does your oil ever go milky under the oil cap? Mine used to with the low temp mishimoto, im sure it was the ethanol/water.

the Nismo was about 6 degrees warmer than the Mishimoto from memory.

No, never milky under the oil cap.

      No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.

      God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.

      Nah, that is hella wrong. If I do a simple linear between 150°C (0.407v) and 50°C (2.98v) I get the formula Temperature = -38.8651*voltage + 165.8181 It is perfectly correct at 50 and 150, but it is as much as 20° out in the region of 110°C, because the actual data is significantly non-linear there. It is no more than 4° out down at the lowest temperatures, but is is seriously shit almost everywhere. I cannot believe that the instruction is to do a 2 point linear fit. I would say the method I used previously would have to be better.

      R33 Fuel Pump & Brakes after alarm swap

      When I said "wiring diagram", I meant the car's wiring diagram. You need to understand how and when 12V appears on certain wires/terminals, when 0V is allowed to appear on certain wires/terminals (which is the difference between supply side switching, and earth side switching), for the way that the car is supposed to work without the immobiliser. Then you start looking for those voltages in the appropriate places at the appropriate times (ie, relay terminals, ECU terminals, fuel pump terminals, at different ignition switch positions, and at times such as "immediately after switching to ON" and "say, 5-10s after switching to ON". You will find that you are not getting what you need when and where you need it, and because you understand what you need and when, from working through the wiring diagram, you can then likely work out why you're not getting it. And that will lead you to the mess that has been made of the associated wires around the immobiliser. But seriously, there is no way that we will be able to find or lead you to the fault from here. You will have to do it at the car, because it will be something f**ked up, and there are a near infinite number of ways for it to be f**ked up. The wiring diagram will give you wire colours and pin numbers and so you can do continuity testing and voltage/time probing and start to work out what is right and what is wrong. I can only close my eyes and imagine a rat's nest of wiring under the dash. You can actually see and touch it.
