What should the oil temp be in a RS?

[aslsw]

bradw's posting about the engine temperature in the 1.8 reminded me of a question I've been meaning to ask you guys and girls.

The Octavia RS has a digital oil temperature read out in the MFD, but there is no indication of what "good" or "bad" should be - unlike the coolant gauge. I've read the manual, including the Australian technical supplement.

Normally it hovers around the 99 deg mark when warmed up, sometimes I've seen it at 102 deg when I drive it a bit harder. But the first time I took it and the trailer camping at the coast, it climbed to around 115 deg by the time we got to the top of the Clyde. My stress levels climbed in synch with the oil temperature! Not sure if I'd be game to do that in the middle of summer.

So, what should it be? At what temperature do I start to panic, shut down the car, call Skoda Assist?

Does it? Mine doesn't.

Does your display have the older red letters or the newer white ones?

I think the newer cars have it - our MY10 Octavia RS doesn't have it, but our new MY10 Jetta does. I think they added it to cars built this year. Golf GTI I test drove had it as well.

Yeah the white MaxiDot has Oil Temp as an option on the MFD. Mine's (TSI) is around 98-102 during normal operating temps. It's not ever been as high as 115, but then I've not been driving with the Oil Temp as the primary focus.

I don't think 115 is much to worry about, especially when the engine is working hard. Comparatively speaking the BMW 135 can have normal operating temps for the oil around 120!!

Mine seems to hover around 102 degrees too!
Sounds quite consistent to the above...

One thing I have noticed about the TDI though is it takes a lot longer than my previous TFSI to warm up.
Both engine and oil temps...

IIRC, max temp for mineral oil was 250f (121C). Synth was 150C. I think the break-down point is above this.
Drop a line to the techo folk at Shell (Shell Helix Ultra plus) and Penrite (eco10 or whatever it is) and ask them what they think. Don't waste your time with Skoda Assist.

If you are regularly hitting above 120C then I'd think about 7500km oil changes just for peace of mind.

Other than that, I find a lot of the info given by gauges to be irrelevant & something to make us lose sleep at night.

^^ What he said.

Notice how the temp gauge on most modern cars doesn't move at all once warm? It's been designed like in order not to worry / distract the driver - how likely do you think it is that your car remains on EXACTLY 90 degrees water temp no matter what the conditions.

If you are getting it to 115, I'd just recommend that you make sure you give it a chance to cool down before you turn it off.

I can't remember where I read it, but on VWs, you can adjust how sensitive the water temp gauge is. That's why it goes up to halfway & stays rock solid. So if you really wanted to, you could get in there with VCDS & remove the "variance tolerance" so that the temp gauge moved around a bit depending on how hot the water temp is.

Our Commodore does this (needle moves all over the shop) and it gives me the poops. I'd rather have it like the Emporors Clothes & just believe that it's OK.

Diesels always take a lot longer to warm up than petrol engines.

I just picked up my MY11 RS TSI and after a bit of driving (with oil temp showing) it varies between 85 and 100 in normal driving, and was up to 112-115 in spirited mountain driving (not full on thrash, rather ride the torque between 2500-5K) It came down reasonably quick when it was settled down on the highway. (although even though they said it doesnt need run in, im still not sitting on constant revs, and changing revs often and loading and unloading engine)

From a mechanical perspective, dont stress, Modern Synthetic motor oils are happy up to 135-140. Yes if your doing a lot of Clyde Mountain runs then get a 7500klm service for oil and filter. If your over 140deg then worry.

dont stress at 115 its nothing.

Yes new oils are happy up to 135-140 but is the temperature measured at its hottest point in your engine?

[aslsw]

Thanks for the advice everyone. The high temperature is not a regular thing, I just noticed it on the first occasion that I drove up the Clyde Mtn with the trailer. And that shouldn't be regular either - maybe 3-4 times a year at most.

So, at this stage I won't panic but when I drive the mountain with the trailer on I WILL be watching the oil temp.

[brad]

My car hasn't got an oil temp gauge and I don't think I'm missing out not having one. If you didn't have the gauge, you wouldn't look at it & would continue to drive up Clyde Mountain in blissful ignorance. One of the reasons I didn't fit the Kufatec kit.

We've even had a few cars now without a water temp gauge. Blue light for cold, no light for "hammer it", red light for "somethings wrong".

My comments where just based on 15 years of motor racing experience where the oil temp was always measured in the Pump or Sump so you are getting the average, of course the oils going to be intensely hot when its sprayed up underneath the piston to the gudgeon pin area, but these cars have oil coolers, although small, but they do a decent enough job.
