ok i know this has been brought up probably a thousand times and ive even read a couple of threads on engine oil but i dont get it all the 20w to 50w or sumthin all that stuff just trips me out so i was wondering what the best engine oil would be for my car i have a 1993 r33 gtst and its done 101 000ks if that helps

The first number basically tells you how quickly the oil will be circulated from a cold start. You need a 0 or 10 there.

The W isn't all that important, but it's hard to avoid. It means "Winter", but I'm not sure exactly how it works.

The second number tells you how well protected the engine is while running. It depends on the engine as to what number you need, but the Nissan spec is 30. You could go to a 40 if you like.

The other bit you need is the SAE specification. I think it's up to "SM" - anything above "SJ" should be ok. This is basically a measure of all the additives, and how well they should work.

Synthetic is probably the way to go, but a semi-synthetic or full mineral will still work.

Stick with the brand names - Mobil 1, Castrol, Penrite, etc - and you should be ok. Avoid the "generic" brands - K-Mart, Woolworths, Target and the like. The regular Woolies Catalogue can offer good prices for oil.

Motul 8100 xcess 5w40 Fully synthetic is what i use in my 33. Prices range from $75-$80 for 5 litres. A lot of people on here use the Motul Chrono but thats over $100 and is only sold in 4ltr and 1ltr bottles. Noticed your car has done 100 000k's have you changed timing belt etc? if not it would be advisable.

Motul 8100 xcess 5w40 Fully synthetic <--- good stuff here..i used it for my R34 GTT...but thinking using the Motul 4100 next time...

Use to use Motol Chrono, very good oil mate you can't go wrong but for $100 for 4 litres it'll depends on your pocket cause remember 4 litres aren't enough.

Neway I'm using royal purple now around $80 for 5 litres and it's doing a very good job. I've got about 110 000 KM on the clock and around 250 RWKW so it is a good oil.

To me oil is something that people shouldn't be tight about. Amazes me how some people can complain about spending $80+ on oil every 3 or so months, yet it's the same person that spends $1000 on gauges and $400 on a blow off valve. (Not talking about any one specific but more so of what i see through work).

i swear by castrol edge 10-60 which costs around $75 depending where you get it from

Unless your belting it hard on a track thats a tad too "thick" in the ways of viscosity.

Oil depends on how you drive. If you are the "average" skyline driver that takes it easy when its cold then gives it a bit of stick while its warm any where from the 5W30 to the 15w40 will be ok. Basically the more you belt the car the higher the oil temp gets, which decreases its viscosity. If you are on the track you want something "thicker" because the oil will get to higher temps make it "thinner" (very very basic way of thinking about it)

go redline oil number one choice and then motul anything else really don't get a mention in my books you would be surprised how much of a difference a good oil makes to the performance of a car turbos spool faster engine revs easier and not too mention its better protected

    • 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.
    • 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.
    • So I found this: https://www.efihardware.com/temperature-sensor-voltage-calculator I didn't know what the pullup resistor is. So I thought if I used my table of known values I could estimate it by putting a value into the pullup resistor, and this should line up with the voltages I had measured. Eventually I got this table out of it by using 210ohms as the pullup resistor. 180C 0.232V - Predicted 175C 0.254V - Predicted 170C 0.278V - Predicted 165C 0.305V - Predicted 160C 0.336V - Predicted 155C 0.369V - Predicted 150C 0.407V - Predicted 145C 0.448V - Predicted 140C 0.494V - Predicted 135C 0.545V - Predicted 130C 0.603V - Predicted 125C 0.668V - Predicted 120C 0.740V - Predicted 115C 0.817V - Predicted 110C 0.914V - Predicted 105C 1.023V - Predicted 100C 1.15V 90C 1.42V - Predicted 85C 1.59V 80C 1.74V 75C 1.94V 70C 2.10V 65C 2.33V 60C 2.56V 58C 2.68V 57C 2.70V 56C 2.74V 55C 2.78V 54C 2.80V 50C 2.98V 49C 3.06V 47C 3.18V 45C 3.23V 43C 3.36V 40C 3.51V 37C 3.67V 35C 3.75V 30C 4.00V As before, the formula in HPTuners is here: https://www.hptuners.com/documentation/files/VCM-Scanner/Content/vcm_scanner/defining_a_transform.htm?Highlight=defining a transform Specifically: In my case I used 50C and 150C, given the sensor is supposedly for that. Input 1 = 2.98V Output 1 = 50C Input 2 = 0.407V Output 2 = 150C (0.407-2.98) / (150-50) -2.573/100 = -0.02573 2.98/-0.02573 + 47.045 = 50 So the corresponding formula should be: (Input / -0.02573) + 47.045 = Output.   If someone can confirm my math it'd be great. Supposedly you can pick any two pairs of the data to make this formula.
