Oil Change Before Track Day!

[Zaver]

Hey guyz, im finally getting the oil changed in my car and have a decided to use Motul Turbolight 4100... Well i use it for everyday use but my car will be seeing the track in few days and that is the main reason im changing the oil now... But i need it for all round performance which would be track as well as Day to day!!

So what vicosity oil would u guyz recommend?? I was a little confused with the 0w40 and 10w40 when the mechanic asked me today!! Or should i be using some other vicosity!!

And what sort of oil filter should i pick up and from where...

BTW i have a R34 GTT pulling 180KW at the Rear...

And what brake fluid should i buy , will just top that up as its a little low...

on my first track day i found the yum cha fluid to goto shit after a three'ish laps.

i would bleed it off. i was recommended motul rbf600. seems to work well. ive done 3 changes with it. get it from autobarn etc

there is a missive thread on oil in gen maintenance.

ive been using 4100 10w40 and changing very frequently (2-3 track days), its goes dark pretty quick. but most would recommend chrono v300. its exy, tho

not more than doing a rebuild on your engine but...

was going to give 8100 a try, but its lighter? once the 4100 is hot the pressure is quite low.

depends on the milage and health of the engine, a tired engine with blowby issues, -50 or -60 which is the hot rating. A healthy engine -40 is the way to go, the 0w40 will protect better when cold than the 10w40, but Turbolight only comes in 10w40 (still nothing wrong with it 10w still protects very good when cold).

the 0 and 10 refers to the weight when cold. 0 is thinner when cold (or is it the other way round???) but either way, the lower the number the better it is for cold weather and coming into summer the cold range of the oil is going to be less important than a few months ago so 10w will be fine
