Sorry to sound stupid but from the first post should I consider Motul 300v to be the best oil to use? Where can I get some?

I have a R33 RB25DET daily driver so should I be using 10w30?

Thanks in advance!

I dont think 30 is high enough, personally id go for a 10w 40, if the engine is using oil then increase it to 50

300v is a good oil , its a mixed opinion subject, but most high quality synthetic oils are good enough, i prefer to pay more and feel reassured, I found Mobil 1 Gold to be a good one, currently using Royal Purple but might switch back next change..

It's only got 80000kms and doesn't seem to be using much oil at all, also temp needle never over half.

Previous owner said he always ran Motul oil but not sure which one, I'd like to continue using the same one because its a nice drive feel ATM, so 300v is the best choice then?

Also does the oil filter make a huge difference? It's got a light blue one in there now, can't read the brand.

sougi bit hard considering its off the road. i got a btach of mobil1 5w30 for free from work the other day put it in seems to be ok so far but when warm the oil pressure on idle sits at about 20psi on the autometer guage

300V is probably overkill for a daily at stock power, can't get it in 10w30 without mixing anyway. Maybe if it had 300kw+ on the street, or was taken to the track I would spend the premium for 300v.

4100 turbolight (10w40 semi-synth) would be more than suitable if it's a stock rb25det, next step would be 8100 (full-synth) x-max (10w40) or x-cess (5w40), then 300v (full synth double ester)

It honestly is a complete waste of money. Get a nissan oil filter and motul 8100 xcess or the full synth sougi one if anyone still has it (probably not).

300v is over $100, if you change it every 5,000 that is $2000 over that time! you could buy a whole new motor and have change for that haha.

I think mobil Gold is my choice, i never used oil using that one, now i use a little with royal purple.. so who knows lol

$2000 over 100 000kms

for alot of people who dont daily drive there cars thats like 10yrs +, twice a year change, so $15/month for the best oil, but lets not go into too much detail here ok, lol :whistling:

You are right, but most people will keep their skylines for what ~5 years before upgrading or moving on yeah? It is just putting it in perspective, the better oil really won't make ANY difference, might as well save your cash yeah?

Its not like it is an 8 second drag car where it might means you get 20,000kms out of the motor instead of 10,000.

yeah thats right,

could really just put shell helix in , probably wont notice the difference over a few years, i just dont like to skimp, but probably end up doing the rb30/25 deal eventually cause i dont wanna sell after spending thousands on it now..:unsure:

Exactly, something I keep saying, 25w50 $5 oil will almost certainly not kill your motor, probably burn a lot of it and might clog the turbo feeds eventually but it won't be instant death.

Might not sound/feel as nice though whistling.gif

Roberto, the guys above are all dead right. I've never read a bad word about motul 8100 or 300v. But you can experiment with oils, see what you like. Just change every 5000km and you're sweet (some oils may last up to 10000km, your call on that).

On filters, I seem to remember buying k&n filters for $22. k&n are a fairly well known brand, the filter is almost certainly going to be better than ryco or nissan, and for a couple of dollars more I thought it was worth it. Also, and MOST importantly, it has a nut on the end so you can use a spanner to take the filter off when it's time for a change :D

Drift do on their filters too, I once picked up 3 drift filters for $20 each from autobarn on sale, was very happy. It's worth keeping a look out for oil and filter sales and stocking up.

Oil change diy, follow this and you'll be sweet.

    • @Haggerty this is your red flag. In MAP based ECU's the Manifold pressure X RPM calculation is how the engine knows it is actually...running/going through ANY load. You are confusing the term 'base map' with your base VE/Fuel table. When most people say 'base map' they mean the stock entire tune shipped with the ECU, hopefully aimed at a specific car/setup to use as a base for beginning to tune your specific car. Haltech has a lot of documentation (or at least they used to, I expect it to be better now). Read it voraciously.
    • I saw you mention this earlier and it raised a red flag, but I couldn't believe it was real. Yes, the vacuum signal should vary. It is the one and only load signal from the engine to the ECU, and it MUST vary. It is either not connected or is badly f**ked up in some way.
    • @Haggerty you still haven't answered my question.  Many things you are saying do not make sense for someone who can tune, yet I would not expect someone who cannot tune to be playing with the things in the ECU that you are.  This process would be a lot quicker to figure out if we can remove user error from the equation. 
    • If as it's stalling, the fuel pressure rises, it's saying there's less vacuum in the intake manifold. This is pretty typical of an engine that is slowing down.   While typically is agree it sounds fuel related, it really sounds fuel/air mixture related. Since the whole system has been refurbished, including injectors, pump, etc, it's likely we've altered how well the system is delivering fuel. If someone before you has messed with the IACV because it needed fiddling with as the fuel system was dieing out, we need to readjust it back. Getting things back to factory spec everywhere, is what's going to help the entire system. So if it idles at 400rpm with no IACV, that needs raising. Getting factory air flow back to normal will help us get everything back in spec, and likely help chase down any other issues. Back on IACV, if the base idle (no IACV plugged in) is too far out, it's a lot harder for the ECU to control idle. The IACV duty cycle causes non linear variations in reality. When I've tuned the idle valves in the past, you need to keep it in a relatively narrow window on aftermarket ecus to stop them doing wild dances. It also means if your base idle is too low, the valve needs to open too much, and then the smallest % change ends up being a huge variation.
    • I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.
