I know you have already discussed the oil thing but im a little worried about the oil ive used in my g. i live in New zealand. Down here i was recommend to use 10w40 synthetic the sales rep then recommended i use penrites new and improved 10w50 full synthetic which has replaced the 10w40 altogether whats your guys thoughts on this thanks

 

The manufacturer recommends 5w-20 and thicker oil is not good, that is why 90% of engine wear occurs at cold startups. This is a great read:

If you can't get good quality off the shelf synthetic oil out there like penzoil (not m1) for peace of mind I would go to the dealer to buy my fluids. If those are out there... Never been. I used to buy AMS oil online ahead of time, it really was convenient to have it waiting at my door with a nice filter too. Don't skimp on your filter, I run Bosch, K&N, AMS, or OEM.

 

50W is way over the operating capabilities of this engine. Stick to 5w30 or close but no reason to run any higher in a daily.

 

Never take the word of a sales rep on any subject especially what weight oil to use, most are not knowledgeable enough to give advice. Nissan recommends 5W/30 state side and I would run pure synthetic because it runs cooler and cleaner. New Zealand must have dealerships, ask what weight oil they use?

I'm running 10-30 in this area as the temps rarely drop below freezing.

 

+1 .. the owners manual actually has a temperature scale and weight listing. take a gander.

for the 2c on my part, If google is not lying and your average weather temp is indeed 10-Celsius on the LOW end .. stick to 10-30 per the manual and go full synthetic. go with the stuff made from natural gas.

 

Seams you guys in the states have a different opinion than that of Australia and England guys over there are are running 0w60 5w50 10w50 10w40 ive got 150km on my engine so thought i would get more protection useing 10w50 full synthetic when the engine was at optimum temp only had the beast for a week want to look after my new baby

 

Are you talking about other Nissan VQ35DE drivers?

 

Yes vq35de drivers. the oil was ok in mine i just toped it off with 1 lter of this 10w50 full synthetic should be ok shouldnt it or do i need to drain it

 

You're all severely misinformed. Your weight of oil is dependent on the temperature of the environment in which you drive it. I ran 20w50 conventional in my G for about 2.5 yrs before I switched to syn blend. Guess what happened..? Nothing. You get a little better gas mileage with thinner oil, but more compression with thick.

There is no "one size fits all" oil, and it should be dependent on your specific situation. I've run everything from 5w20 synthetic in my old Honda to straight 40w in my old dodge truck, and 20w50 in multiple cars.

Thicker oil = more cushion for the pushin, baby. Just not to be used in cold.

I run Royal Purple 5w30 year round in my G but I live in st.louis where it could be 80 degrees one day and 10 the next.

 

Thats the impression i got just went to my mechanic spoke to the big boss there and he reassured me i had nothing to worry about so peddle to the metal for me watch out fuzz

 

Fer sher, that makes sense. I live in San Diego where its 80 everyday of the year. No reason not to run 20w50, except I changed to syn blend which has better cooling properties so I switched it to 10w40 for the better mpg.

That's why car companies recommends super light oil: they have to adhere to govt mileage regulations. The lighter the oil, the less resistance.
