For the first 6 months until we see MK6's everywhere we also get a smug git gauge. Mines running at full boost all the time :grin:

I used to have mk2 GTIs which were the last ones to have an oil temp readout on the MFA.

No they weren't...my Mk3 has it too!  :grin:

I tend to stick to below 3000RPM and as little load as possible until it starts to show a value on the display as opposed to ---, then as the temperature climbs, start using it normally. I'd say 80+ would be OK...

I have seen 116 degrees on my Mk3 16v.

Reducing my Golf count by the week....
..but gaining motorcycles.

How right you are!  :embarassed: My daily driver is a mk3 and it has one too! I'd forgotten as I only use the car around town and never really look at the MFA unless I want to depress myself looking at the fuel comsumption.
I still don't class the mk3 as a proper GTI though as it doesn't have a black headlining!  :grin:

Ideally you want to keep your oil under about 120 deg

That advice is only really relevent for older style oils, or oils from American manufacturers who use Group3 basestocks.  Better quality European souced oils, which use Group4, or the even better Group5 basestocks - should have much higher tollerances - upto 150 deg C will be fine.  The VW LongLife oil standards include a 'HTHS' test, which means 'High Temperature, High Shear' - and this includes a continuous test at 150 deg C.


Modern oils are very much better than the old oils though

Some modern oils are better, but others are just full of marketing hype - the most noticeable is the company who sponsor 'The Grid'. :sick:


but then again the GTIs have turbos and put out a lot more power than in days of old so the oil gets put under a lot of stress.

The turbo is THE crucial issue. :nerd:  Hence why a turbo petrol should NEVER be on LongLife servicing. :sad:

More importantly, I think, is to make sure your turbo cools down before switching the engine off when you're been running the car at speed.

Yup, crucial. :afro:

I'm sure T_T will be along to put us right once and for all....... :smiley:

Have I done my 'duty'?  :laugh: :laugh:

Just over 100 for me, TT said start driving enthusiastically after about 85 I think.

Yeah, it is around 85deg C when the oil has reached its maximum abilities.

Out of interest, how long does that continuous test last? And would you have a copy of the VW504 00 test requirements?

The continuous test lasts for 625 hours, which is over twice the ACEA A3 300hour duration.  I don't have the actual test standard on my lappy, it is on my foobaar'd desktop.  What does google throw up?

I tried, but Google throws up too many RTFM forum conversations about "which oil should I use". But 625 hours answers my question - cheers. Should be adequate to cover any spirited long distance drives I make into Europe (625 hours at 120mph = 75000 miles!)  :grin:

All this testing and they still can't make a car that dosn't split valves, corrode wheels, rattle, fill it's lights with water and sound like a diesel.
