Best Oil For Rb26?

[Kinks]

fair enough. i have only heard good things about motul oil so would be surprised if it was the cause of an engine meltdown. anything can happen I guess.

10w 40 and two engines, oilcooler on second, unless there's somthing inside this one i don't know about but it should be stock and been in place for 3 years.

The factory workshop manual recommends 7.5w 30 sg grade ( but thats for japans weather ), 4.2 liters without filter change and 4.6 with.

Your engine failure wasnt due to the oil

Its due to a LACK of oil

Not sure could be alot of things but lack oil certainly not i have always made very sure the oil level was just over the full line ( about 3-4 mm ) before every time i went on to the track, both happened on very hot days ( 30 DEG and up ), one at Wakefield and one at Eastren creek and so i've stopped doing track days when its over 30 DEG and that seems to be working.

You need to overfill by a litre

Best oil is no oil!!!!

Go electric!

motul 300V is good enough for many factory race cars including nismo. it's good enough for me. franky, i'm not sure why your engine didn't 'like' it, but I'd say it's some problem with the engine, not with the oil. I have now been running it for 3 years. oil pressure at 80degreesC at 3000rpm is 6 bar.

If its all standard approx 4.5 Litres with filter of course, Enjoy your first journey of removing the oil filter from standard location its not fun

Its actually not as hard as everyone says it is . You just need to be standing in the right position (awkward) and get a backwards grip on the filter to pry it loose, then your home free.

I just hate the cleanup afterwards ....

Main reason I haven't got a remote setup is because I don't mind the little extra effort it takes on an RB26.

My oil = Mobil 1 10W30. For $85 for 5L it better be as good as the rest.

Yes many factory race teams probly do use motul oils but 300v we can buy of the self not likely,

6 bar 3000 rpm is to high when the recommended pressure at 6000rpm is only 451 kpa ( 4.51 bar, 65 psi ) as per workshop manual ( page 39 - en-22 ),

the first engine spun number 6 big end which i'd put do to tight off camber corner and the oil pick up drying out but the second one was all 6 and mains and to me thats oil failure,

which was not my point to start with, the point is stock or near stock GTR street driven buy any oil thats full syn and it should be just fine

6 bar at 3k rpm when warmed up sounds high. i only ever hit 6 bar when my engine is dead cold, when running it's 1-4bar depending on idling vs driving.

some people reckon that pressure is just a restriction of flow and that high pressure is a bad thing - means you should be using a lower viscosity oil.

i think having "some" extra pressure when stressing the engine is a good thing though. you want to make sure the oil is forced into the bearings and stuff.

Having used 3 types of oil since owning my GTR, including motul 4100 turbolight, motul 300v, and Neo platinum - all 10W40, i'd have to say the 300v came out on top. Pricy yes, but the car was alot smoother than either of the other 2.

Its only really pricy the first time you use it, because you need 2 bottles to put 6L into the motor (or so ive been told) so the next time you'll only need the 4L (1 bottle).

^^ that is lack of oil to a tee mate

yeah as i said, i have to find out what was wrong with it by giving it another go.

i know for a fact though it is one of the best products money can buy.

I'd say lack of oil before failure of the oil itself.. if the oil came out seeming normal then it's not that. if it came out runny as water and smelling burnt then yes it may have been a problem with the oil.

[XKLABA]

yeh like water considering i put it in the day before the track day as i always do it was black as the ace of spades and very much like water, not lack of as i said before i always check my oil level before going on to track.
