Weight Of Oil For R32 Gtr

[seventhirteen]

I know this topic has been beaten to death numerous times but I just wanted an experienced opinion on what weight of oil you guys would use in my car.

Its an r32 gtr 94 model with about 130k kms on the clock and no serious mods (basically stock). Now seeing as factory weight is 7.5-30, in your opinions would you guys go full syn 5w-30 or 10w40?

[Ben C34]

I would go 10 40.

Your engine is old.

[seventhirteen]

Yes it is old, thank you for pointing that out. So why go thicker? My car isn't burning or leaking oil so is there a reason to go thicker?

[Ben C34]

As the engine wears the clearances get larger. To maintain decent oil pressure a thicker oil would be required.

Do you have an oil pressure gauge? How is the oil pressure now? If it's fine jeep using whatever you are using.

[seventhirteen]

Yeh on the factory oil press gauge it sits about half way when driving and drops a bit on idle but I've heard that the factory one can be a bit dicky sometimes.

I think I will go the thicker then.

Also do you know of the sump capacity by any chance?

Just go buy some 5W50 Mobil 1. It is cheaper than the thinner grades and far better than the SEMI SYNTHETIC oil Nissan originally specced. Get the 5 litre container and tip all of it into the motor.

Not a fan of the Mobil 1 5W-50.

I run Penrite Premium 5 (5W-60). Their racing 10 (10W-40) was fine with two track days.

My engine's pretty much the same as yours.

Nulon or Penrite, keep it Aussie!

[BuuBox]

Without a functioning oil pressure gauge, or knowing the history of the engine, you should err on the side of caution and run at least a 10W40.

Sump capacity is allegedly 4.5 litres, but put 5 litres in.

Run 6. Middle of the hump.

[MrStabby]

AFAIK the only good reasons to run a thicker than specified oil is to;

1. Return oil pressure to spec on a worn motor,

2. Provide a safety margin in a motor that is overheating the oil,

3. Make an engine run more quietly, however, higher noise does not appear to correspond to higher wear

I run Mobil 1 0W-40 in my Stagea daily and in my street, but tracked, GTR. IMO its a good bang for buck oil. In the stag its still good after 6000kms so ill try 7000kms and re-test this fill. I will test the GTR @5000kms next change.

On a stock motor a ?W-30 should be fine as long as the oil pressure is within spec.

Alright so ended up getting the Penrith 10w-40.

Thanks for the replies guys, appreciate it

If your engine explodes let us know

[Sinista32]

Lol - "Penrith" oil is likely to be hash oil. So it's likely to be awesome in cabin as it burns off

surely Penwrite

Hahaha Penrith.

Did you get the Racing 10 or their semi syn?

[jiffo]

I'm giving Valvoline Synpower 10W50 full synthetic a few tries.

Engine has 125,000 (by the clock).

[niZmO_Man]

It'll be fine.
