Cheers

had my car car on the dyno the other day had to change my oil before it went on. the dude that did it told me that castrol gtx 530 is the best for em.

Nissan reckons 10w30 is the best oil, so I've been using Valvoline 10w30 Semi-Syn, has been smoking a bit less lately.

is full syn not better to use then

[JayM35]

Yeh, i'll try that next go.

Usually it gets serviced at workshops(warranty rule) and mums work uses Penrite, which made the car smoke a bit when cold.

I was thinking of dropping in some of the new penrite full syth range they have realesed.. You can get all different weights, I hav normally steered clear coz most fully synth oils are too light for my liking...

I have tried a multitude of oils in mine, although I only stick to grade 4 and 5 oils. I have found for the m35 a 10w40 is perfect, anything thinner and it runs a bit noisy and thicker it doesnt seem to rev as easy.

The VQ burns a bit of oil at cold start but it isnt past the rings or valve seals, it is the pcv breather on the plenum. It dribbles out of the pipe down the middle two runners and onto the valves just waiting for you to start the engine. It can be stopped by installing a pressurised catch can but then you will need to empty it of water and oil monthly.

I don't know why you get water in your catch can Scott. I certainly get some oil but never any water....

For hydraulic lifter engines - Castrol Edge 10W-60

For solid lifters (ie RB26) - Kendall straight 60W

No oil is any good unless to totally refrain from flogging it until up to full temp.

It used to be water, condensate out of the oil from the cold Melbourne winters, now I get ethanol evaporating out of the oil also.

Are you running the stock thermostat? I had to go back to it as the water and ethanol wouldnt evap at the low temps...

I have the Nismo thermostat fitted on my car.

There you go, water wont evaporate very well at those temps, does your oil ever go milky under the oil cap? Mine used to with the low temp mishimoto, im sure it was the ethanol/water.

the Nismo was about 6 degrees warmer than the Mishimoto from memory.

No, never milky under the oil cap.
