Ummm... I think he said 5w50.

Which is what I use, over filled (to the bottom of the bump on the stick) ofcourse.

I think 10w30 would break down too early in an RB turbo engine (engine gets too hot for that oil).

Sorry yes 5W50. Same thing really. Still nice and thick.

The M1 10W30 won't break down in an RB. Its fully synthetic PAO based oil so it can handle the stress without breaking a sweat. Hell Nissan's OEM oil is 7.5W30 mineral stuff so if that can do the job...

Your average RB doesnt run any hotter than any other engine, why would you say that? The turbo is water cooled anyway so the turbo isn't as hard on the oil as the days of old.

i run 10w30 because i get it from work.. does the job and have no probs with it at all..

the numbers given to the weights of the oils r over rated ne ways... 50 is a large cold weight and 0 is just bull shit.. just oil componeys claming crap ( i know they go through sia testing)

50 is not the cold weight. It is the measure of the high temperature viscosity.

As for the numbers being crap, it is easy to compare the difference between two grades. Just tip some out of the bottle - it will suprise you how different they are.

Essentially, to compare the 5W50 to the 10W30 they are basically the same oil, just with different viscosity modfiers. The 5W50 will be "thinner' when cold & "thicker" when hot. This is a relative thing as obviously the oil's viscosity will decrease as it gets hotter.

At the end of the day you will be marginally better off with the 5W50 because it is more stable, most noticeably when hot.

is it 5W50, or 5W30? cause 5W50 sounds like a pretty thick oil to me.

its definitley 5w-50.... but u can buy 10w-30 aswell....

when is oil at its thickest? i never drive my car for longer than 50 mins at a time, i dont go on long trips.... so what would be better for me?

im only ever doing little trips to work and stuff... never big road trips..

Beef

whether you drive for 20 mins or 5 hours, once the car car has come up to operating temp the oil temp shouldn't rise (unless you are flogging it). normal oil gets thinner as it got hot, but multigrade oils are designed so they don't thin as much.

Edited by mad082

just doing a bit of research, normally oil thins at higher temp. multi-grade oils have polymers that stop it hinning too much (so its thin when cold, and not too thin when hot). the dissadvantage with high range oils (big gap between 1st and 2nd numbers) is that they are more prone to breaking down. it is the oil that lubricates, not the additives, so the less additives, the better.

Hi Guys,

There was mention above of filling oil past the MAX to the BUMP. I was told by one mechanic that this reduces the change of oil surge and is ok but by another mechnic that filling past MAX on the dipstick can cause potential damage. Can I get some sort of common consensus on whether this is ok?

Cheers.

    • Thanks for all the replies fellas. Gonna finish putting it back together and see how it handles the set up. If it starts pinging it’ll be parked.
    • Well, I can recommend the partial AV system translation CD I ordered from Car Audio Workshop in NZ. Whilst it didn't address the date issue, it has conveniently translated on-screen menu items into English, and now allows the GPS-received time to be offset in hours rather than minutes, so I can display Eastern Australian time accurately ( and bump it by another hour when daylight savings starts ).
    • Yuh, if it's 45°C outside, my car is driving in it.
    • I'd be curious to hear more. Otherwise, have you driven a modern x-trail? I wonder how it compares. Here in Australia they are/were popular for rentals and fleet vehicles. I have been in some and my impression was they are bad. But, this may have been very different in the 2000s at a good trim level. Twenty years is plenty of time to make the model worse. I do very much agree with the 2 silver cars in the garage approach. But, not driving because it's too hot would not leave a lot of time in the year for many Australians. I don't think you need to worry too much unless the car has actual issues with overheating. 
    • Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.
