Lubricating Turbos

[dal59]

Does the engine oil also run thru the turbos to lubricate those as well as the engine?

[Yeoman]

The blinker fluid takes care of that.

??????????

[JohnEnglish]

Yes.

[dal59]

I suppose I need to set my expectations for this forum even lower.

You had expectations?

I thought posting here was like throwing your words into the wind


Yes, your oil flows through your turbos, as does your coolant. That's why turbo cars are more harsh on the oil and it is important to run quality oil and change it accordingly

Wow, thank you!!! There are a handful of members (like you) that jump in and truly try to help. However, I do sometimes get discouraged with the responses, or lack of responses, from time to time.

Before I ask a question, I always refer to my owners manual and research online. However, If I feel like I am still not getting a complete answer, then I come here to ask others that have the same vehicle and may have the answer I am looking for.

In this case, I read that some manufacturers have a separate oiling system. And, much more specifically, I had just read an article that in 2020 Audi started introducing electric turbos on some models. Some of which included our 2.9 engine.

Again, thank you for your time and consideration.

tks, dal

I suppose I need to set my expectations for this forum even lower.I’m not too sure what you were expecting. You asked a yes or no question. If you wanted additional information you should have specified that or asked additional questions.

With the flow of the responses it read differently to me.

It read as though you were confirming the response I originally received regarding "blinker fluid".

I should have realized a veteran - four ring member would tend to be helpful. :) Thank you!!!

BTW - The reason I was asking was because how quickly the oil temps can rise 20 degrees after a couple of short, dynamic - full boost blasts. Obviously red lining the engine alone would do that, but I thought if that same oil were now also having to cool off the turbos which are spinning at crazy rpm', it might tend to make the oil temp, rise very quickly. It also goes back down nearly as quickly once you stop and go back to normal driving.

[JohnEnglish]

I've found that driving in S mode will keep the oil temperature a few degrees higher than driving in D mode.

I remember the days of turbo timers with older turbo cars running dyno oil when turbo cooling was a bigger issue. I think our manual says drive in chill mode last few minutes for cooling.

Sent from my iPhone using TapatalkIf you turn off the car and the turbos are still hot, the cooling fans and electric oil pump will run for a few minutes to circulate the oil and cool it off. It happens to me often after a short drive, the cooling fans will run for about 5 - 10 minutes after I shut off the car.

Interestingly, this post began because I was reading an article about Audi. It stated that in 2020 Audi started using electric turbos in some of their models. And, while the RS5 was not listed, our engine, the 2.9L 444HP engine was listed. So, not knowing for sure, I started to wonder. Anyway, some of the main advantages they listed were keeping the electric turbos cool and avoiding turbo lag.

The electric compressor spools up almost instantly to provide boost and then shuts off once the main turbos kick in.

Now that is pretty cool! Glad to hear there is a solution to turbo lag. Too bad it right before electric engines take over the world and make turbos a thing of the past. At least that is what my Tesla driving buddy tells me. I forwarded him the article about VW/Audi's plans to transition away for ICE cars completely by the early 2030s thinking he'd be pleased. Nope. Not fast enough. In his world, every car manufacturer should stop making ICE cars yesterday and immediately switch to electric only. its absurd...

Well, I am certainly glad I was around for the heyday of the ICE. Maybe I cannot afford the best of the best, but I got to see it and buy a pretty good piece of it. :)
