Octavia III VRS 162TSI Oil Temperature

[dinot81]

I know not exactly the topic but to make it little worse, cars like that are usually driven at high speeds in Germany and their service intervals over there are 2 years or 30,000kms for most newer cars. 15k interval for high quality oils is no problem. I have read German VW & Audi forums where owners have mentioned temperatures of 160 degrees at top speeds. Engines still run and no issues with oils.

Well, I wouldn't want to test that out in my own car, maybe in a hire car.

The General rule for engine oil service life is that it is decreased by half for every 10 deg above 60. This is mainly due to oxidation which is the main cause of oil degradation (increases viscosity, depletes additives, increases sludge deposits, increases acidity). So running for long periods at high temperatures is definitely detrimental. Now, OEMs obviously would have to be doing all the development testing to determine what the acceptable limits and service intervals are and we know synthetic oils can withstand higher temperatures being more resistant to oxidation but it still occurs. It doesn't make sense to me to be able to run at those temperatures and still keep normal service intervals and expect a good service life out of your engine.

Saying all that, I'm really not worried that 110 deg cruising is going to damage my engine. It's just interesting that VAG/Skoda would choose to allow higher temps compared to previous versions given for example oil consumption issues they have let alone other engine warranty problems.

Remember that they claim that 1L per 1000km is acceptable! Could you imagine having to use 15L of oil between services?!

I use ~6L between 10k oil changes - I have a 5L oil container in the boot
It's a bit of a pain - you come out of a restaurant, start the car and it complains about oil!
I'm trying the Liqui Molly "Visco Stabil Visco Plus" product which is meant to help

Ouch!! That is pretty bad. If my mkII was like that I probably would not have bought the mkIII. They've both been great cars overall though, nothing else on the market (in my budget of course) was as versatile and fun to drive. Apart from a clutch failure on the mkII I was pretty happy, I'm hoping it doesn't go again within 60thou or I'll be fairly pissed.

My mkII used very little oil over 100,000km. I topped it up twice I think between services with about 500ml.

As mentioned I do mostly highway driving for extended periods so I am at normal operating temps most of the time. I think this has helped keep consumption low, since my wife took it over and does mostly short trip driving I have had to top up nearly as much in 3000km than what I did for the firsts 2.5 years. I didn't do anything special when running in the engine just drove it normally without babying it and pushed the revs higher every now and then through some mountain runs.

Hmm I thought with the FL engine change the oil issues were left behind with the TFSI engine. We saw a bit when new but hardly anything ever since. Certainly no more than around 200ml every 15k at the worst.

Effectively, putting in a litre every 1,000 KM, you'd be changing the oil three times between services, no need for an oil change every 15,000 KM ever!

My Eos with the 155TSI engine sits at or just over 100 in suburban driving and I imagine it would behave similarly to yours at highway speeds, I'm comfortable with that.

After reading this post, I took the old girl out for a spin (140 km round trip). The first 70 km of the journey the oil temperature was between 90 to 93 degrees. On the return leg the temperature rose to 101 degrees and stayed at the temperature.

However, last year going to QLD via the Newell Highway the oil temperature sat on 107 degrees and after a couple of over-takes the oil temperature rose to 115 and slowly decreased to 110 degrees.

I also consider not only the load on the engine but, the ambient temperature of the day plays a part, during winter l have to travel 7.5 km before the oil temp gauge comes off --- to register 50 degrees, and during the summer months a distance of 4 km for the gauge to register 50 degrees...... (but l am know expert just my 2 cents worth)

Off topic note: The engine consumes 250 ml of oil between servicing

What model have you got?

Mine is pretty consistent, doesn't matter too much between 20-40 deg ambient it's pretty much always 105-112 on the highway after warmup.

Mine tend to peak between 101 - 105c, it rarely goes beyond 105c even in the recent Brisbane heat and I always give my car the bean whenever the condition allows me to . I've seen the temp rise to 110c maybe twice. The engine does consumes oil, around about 1.0L of every 8000km or so.

Pushed my MY16 Polo GTI hard on the run home from Bathurst-->SYD-->NTL yesterday after the 12hr race. Hottest I saw after climbing up to Mt Victoria was 106C.

You'd never know/care if the oil temp display wasn't there.

My Mk6 Golf GTI was the same, 113C on a track day at 38C ambient (Wakefield Park)
