I use millers nanodrive 5w 40 👍

[Irfy]

Awesome GTI used millers nanodrive 5w40 in mine (mkII).

Normal spec is 5w30 iirc

[TommyRS3]

I'll go for 5w40 then. Seems to be thicker when engine hot so better protection

Yes recommended spec is 5w30

[TommyRS3]

Many people make the change from 5w30 to 5w40?

If your going for a map, your car will run higher temps so better going for the 5w40

I would only use 5/30 - 504/507 spec oil as recommended by VAG,as for running hotter the RS has a bigish oil cooler at the bottom of the front bumper which would come into play when running at high RPMs & high speeds.
Check the oil temp next time your giving it large & see how it changes ?
The make of oil is a personal preference but as long as it meets the VAG spec you cant go wrong .😊

The Rad in the front bumper is for Coolant.....

The oil cooler is above the Filter housing and has coolant running through it.....

Whats the one on the other side of the front bumper? Gearbox oil cooling perhaps?

 

Come on T-800, do your stuff!

The above is mk 1 RS 3,

The mk 2 has 2 one on each side.

Aaaah, serves right for wandering into the MK1 section

Hi mate would i be correct in saying that the aux side rad is being used as an oil cooler as its connected via a water pipe from the oil/water heat exchange on the side of the oil filter mounting housing ?

Most VAG cars have this type of oil/water heat exchanger but not plummed into an aux rad ?

To me the 'whole' system is interconnected anyway.....

However the smaller one does look as if it's a 'satellite' off the main Rad that connects onto the Gearbox cooler / Oil Cooler.

Item 7 is listed as an Oil Cooler in ETKA parts catalog.

Cheers for that  mate i thought it was more than another rad for keeping the engine water temp in check !

Yes mate item 7 is an oil/water heat exchanger & thanks again

There's 2 off them on the MK 2 Dell.

I presume Audi have fitted the 2nd rad to help control any additional heat that the extra BHP the MK2 may generate in the cooling & oil systems ?

In the past ive dumped the VAG oil to water cooler & fitted an Macal oil to air with great success in controlling the engine oil temp
