Engine Oil

Hi

Just looking for some feedback on what everyone runs engine oil wise in skyline running over 400rwhp. I have used Mobli 1 full synthetic but switch to Motul 300V (10W40) however i have find it burns black pretty quick (change every 5000km).

The car is a track base car (rarely driven on the street).

I have talked to alot of people and have gotten alot of different answer... also i remember reading a topic on sau (i think posted by URAS) about engine oil and a test that was done however i can't seem to find the topic anymore...

Brands im currently looking at are Agip, Shell Helix Ultra 10W60 All were recommend to me by a mech that works at ferrari and deals with them day in day out. They all use the Shell but said some owners ask to use Agip and or elf. Has anyone had any experience with these oils?

Also I notice alot of Japanese tuning houses have their own oil, i know nismo uses motul but im not sure what HKS uses (if its there own blend or they use someone else product)

edit: nismo motul oil

[base oil concept]

* For the goal of engine protection, this ester-based oil was developed by adding polymer ester to compensates for the weaknes in low-temperature performanc of complex esters.

[Allowable torque of approx. 70kgfm (approx. 600ps)]

* This is a high-performance oil developed, through the use in tuning car racing and drift apprications for use in the RB26DETT, SR20DET and other turbocharged engines.

* The oil has high anti-shearing stability, ensuring good oil film retention from low speeds to the occurrence of high torque, with friction loss kept to the minimum possible level. It ensures the high stability required in situations such as the use of NOS, which can cause an extreme increase of torque.

* To ensure the highest posible reliability without sacrificing output performance, a special multifunction polymer has been used with high shear stability as well as improved detergentdispersant quality. This not only ensure oil film but also provides exellent anti_oil-coking performance, for improved lubrication of turbine bearings.

* SAE viscosity: 15W50

* 100-percent synthetic Duble-Ester technology

* Equivalent:API SL

* This oil was developed with the high-intensity driving of competition in mind; please note the two points before using this oil.

* 1. The product is not covered by Nissan Motor Co., Ltd, warrantee.

* 2. When this oil is used, it must be changed after every 3,000 kilometers of use.

Cheers

Plenty of threads on oils... And given plenty of people have 300rwkw these days, any number of threads will give you an idea - because everyone is different.

Here are but a few:

This one is about performance from the first post: http://www.skylinesaustralia.com/forums/Sp...p;hl=engine+oil

One point (before i close), if you are changing every 5,000km's and it's just basically a track car...

You are clearly not changing every 6 months? You should be. 5,000 or 6 months.
