I just had discussion's with my mechanic where i told him i wanted a 10w 40 redline rating in the gtr! What it had!

I find out he couldnt get it and has put in a 15 w 50 version ... NOw i am paranoid about this because of the complex componnents in the 26's head

. He made a statement that i will have better oil pressure because it reads low on the guage ...

I just belive the Gauge is intermitent . and waiting to install a better device..

Now we are talking $130 worth of oil here and i just wanted opinions if i should re change or run it until next change ... What could happen ? Topend ware?

to me the motor is very Quiet and strong with 140,000 km's .. I do know it had its magor service at 100000 belt (Etc)

What do you think ?

Bascisally, nissan recommend a 7.5 w 30.

Thinner cold viscosity helps it to lubricate the engine quicker when it's been sitting e.g. overnight. Most of the wear to an engine occurs during start up.

The warm viscosity isn't as important. But a thicker oil requires more heat to break it down at high temperatures.

Yeah its pissed me off a bit ..... I will do a short change 2000

To be hounest i just want the car outta his shop ...

He came across as knowing a bit but as you go along you realise that he is learning as he is going ... This is the last mechanic to ever touch this Car in the town of Albury Wodonga .. I have learnt so so the hard way ....

it is mega Cold here in winter so it makes no sense again!

Thanks

Yes do your own oil changees and use a nice PureOne or genuine filter.

The 15w50 will be fine, do remember nissan recommend 7.5w30 for a new motor with jap conditions being considerably cooler than ours.

I'd leave it in for the whole 5000k. No need to drop it. :(

As your spending so much on oil consider have an oil analysis done on it after 5k, then drop in the 10w40 do 5k on it and give that an oil analysis too. Will indicate which is better suited to the driving and condition of your motor.

Can you even get 20W50 in a good synthetic oil?

I've only seen 20W50 in cheap minerals oil, good for old XF Falcons and the like.

Have a go yourself, you couldnt, f**k up more then your mechanic already has. Didn't even do as you asked.

it was a case of me swallowing my temper to get my car outta there!

Redline make it in that Viscos For there Big ol Gappy motors in the States .

No, don't dump the oil. Redline being polyol ester base have pretty good cold pour point, i would say used it to 10k before you dump it.

The oil you have will be fine, but if you want to have an argument with the mechanic that's up to you. One-off oil analysis falls into the same category as cryogenic treatment......a complete waste of time and money.

Not a complete waste of time.

Early notification of fuel, water air filter problems... And gives you an indication of the oils VI over your change period.

With regards to wear yes it can be a waste of time.

SteveL it was way more things than just the wrong oil that caused tension.

I simply found out he had BS'd me on a few points > this Was not the Point of the Thread

I Asked here about the viscos because i didnt know and wanted to get the info form people that did, incase of Damage.

Regarding the OIL analysis I just found it Personaly interesting to see what becomes of the oil after a term, not to argue.

Its all good now ... Cars home ,it has its proper oil and the Vl Commie has its own batch now too, Nothing Wasted!

thanks everyone.

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      By Bireley_32 · Posted

      Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.

      The filter only filters down to a specific size. Add to that, the filter is AFTER the pump. So it means everything starts breaking your pump even if its being filtered out.
