[jUsT-dRiFt-iT]

Hi there, just bought a R33 Series 2 GTS25t and the oil is BLACK like totally black , obviously the last owner hasnt changed the oil in a while so i want to flush the engine and was wondering what the best way to go about it is? Cheers.

Just do multiple oil and filter changes within a few kms, like a day's worth of driving, or around the block of eachother. Depends if u wanna do 2 oil changes in a day or not. haha. Also stay away from "engine oil flush" additives...rumor has it they no good for the motor. Have fun.

correct me if im wrong but from what i have read, having black oil is good.. it means its actually doing its job.. alot of the good oil have additives that clean ur engine so it would be suspended in oil for your next service.. having clean looking oil doesnt necessarily mean clean engine etc.. 2c worth

change your oil - and yeah - id change it and then change again within a week maybe

The only reason why people would get shitty about using an engine flush is that when they are used, they will remove a lot of carbon buildup on the piston rings, which in some cases is the only thing that is sealing the compression of the motor from worn rings. They're actually quite effective.

Drop your oil. Fill it with new oil, run it in with an engine flush and then drop it again, if its doing its job properly it will be black as. So that when you fill it once more it should be fine

Mate best way is to use engine flush then drop oil

and maybe repeat process once if fussy depends

on how badly fouled it is inside the engine.With my

car I change it every 3000km and after every track

day with out fail.This is a must if you want a good

reliable engine, oil is cheap rebuilds are expensive.

I have personally seen cam sharfts snap in 2 through

lack of oil changes.Always use full synthetic oil and

you can repeat your engine flush every time you change

your oil just to be safe in get it back to square one.My

oil after 3000km is just starting to lose its colour,you

have to remember that these cars see alot of revs

and take a huge amount of heat.Hope this helps

one oil change is enough..

there is a reason for a new oil filter.
