Engine oil and another Q

[brad]

Righto, let's clear this up right now before someone stuffs up their car.

These specs are NOT INTERCHANGEABLE - 504 is for longlife petrol/507 is for longlife diesel.

The original enquirer to whom I was responding has a 2.0 TDI - hence my discussion re 505/506/507.

The use of 504 spec oil in any 2.0 TDI (or even 1.9 TDI) would VOID THE WARRANTY and probably lead to ENGINE FAILURE.

Highway is wrong - again! Bloody idiots.

Sorry for the caps - but jeez.

As much as I hate agreeing with Mav, he is right. By good planning, coincidence or serendipity all the oils tha have achieved 504 spec have also achieved 507 and viceversa, therefore the oils (not the specs) are interchangeable.

I have done my first oil changed at 5,000km and the oil is really dark black. I have asked the VW dealer mechanic and he said the oil that they use is the Castrol Super Longlife SLXIII. After the first oil changed with the ESP the car now run on another 6,000km and the oil hasn't been black yet, just turned to dark brown. That proved the Mobil oil is better quality and it's running very smooth on acceleration.

...

Oil is supposed to get black. Getting black is good, it means the detergents are working and the oil has good capabilities to handle solids in suspension (rather than them falling to the bottom of your sump).

As Obama says "Black is better".

Not sure who does the testing in Australia for a reasonable price, I know in the US they have cheap kits you can send in and get the result back soon after and it's a fraction of the price here. I'd rather just change the oil on a regular basis though.

There are a number of labs & depending on the level of analysis it can be as cheap as $25. For our work equipment (300L hydraulic reservoirs with major environmental risk when we change the oil) I buy the sample pots in lots of 10 & it works out at ~$35 a test including postage. The suction tool to put the oil straight in the pot without contamination/mess was $125 but you could do it with a $5 bigbore syringe & some tubing.

Castrol did UOA for me twice, 4 years ago, so I think that all big oil companies are able to do oil analysis, it won't be cheap, expect to pay around $100 for one of UOA only.

It's ok, I agree with what you said

.. VW 504.00 - Long-life petrol engines with WIV.
....

Sorry to drag up an old thread but we've just bought a 2007 Jetta 2.0 FSI Tiptronic and reading up on maintenance requirements. The vehicle data sheet indicates that service interval type is QG1 (variable/long life) and I've read that VW's made after 2000 are all QG1 - so I guess that means servicing is due every 15000 kms or 12 months (our Jetta has done only 22000km in 2 years and serviced twice in that time). I'll be doing routine checks to top up oil etc and in reading this thread came across the term "WIV" as in the quoted post. Can someone tell me what "WIV" means or stands for please.

Thanks... O
