Chip Tuning: Higher Oil Temperature?

Hello, diesel enthusiasts!

I'm new to this forum! I also have a question right away: I've installed two tuning chips on my 110 HP TDI! The noticeable increase in power is significant, and I'm very satisfied! However, I'm a little concerned about the oil temperature! Now, I'd like to know from you what the maximum oil temperature is considered safe! When I drive on the highway at 220 km/h (I'm not kidding ), the oil sometimes gets very hot! So, 110 degrees or more is quickly reached!
As a second question, I'm interested in knowing whether using a better oil can lower the temperature. If so, what oil have you had good experiences with?

Thank you in advance for your answers; it's certainly an interesting topic, isn't it?

Regards, MR...

2 chiptunings? Are they on top of each other, or what is the relationship between them, and where did you read the oil temperature from?

Hi,

Below 120°C, it is not critical.
You will find it difficult to lower the temperature by using a different oil.
I can think of two possibilities for that.
a) Higher thermal capacity of another oil, resulting in greater heat transfer capability.
b) better lubrication, which results in less friction heat that needs to be dissipated.

Regarding a), I can't say much, but there shouldn't be any major differences.
b) All oils are suitable for lubrication, and the differences between them in this regard should not be significant.
Overall, I don't see any need for you to take any action.

Best regards, Rainer.

TDIs already have oil coolers or heat exchangers, which are connected to the cooling circuit (coolant). Modern high-performance oils are supposed to withstand temperatures well above 350°C without problems. Just think about the temperatures in the sliding bearing of the turbocharger. 110°C in the oil pan is nothing compared to that. It's not even enough to fry potatoes . Most of the waste heat comes from the combustion process, and not from friction.
The oil temperature in gasoline engines without an oil cooler often exceeds 110°C when running at full throttle.
I would recommend a good synthetic oil. Avoid oils that only cost 5 euros per canister.

I mean 2 tuning chips, because the Motronic of the 110 HP TDI contains 2 8-bit EEPROMs! Thanks for the information! The oil temperature can be displayed using the MFA! Regarding the oil: I suspect that currently, normal 10W40 oil is doing its job in the oil pan! Maybe from ATU, straight from the barrel! Who knows! I recently acquired this TDI and I don't know anything about the oil! However, since I don't know how long the oil has been in there, I'm going to change it anyway! I was interested in what oil I should use for that. Someone told me something about 10W60! However, I have no idea about engine oils and their properties! I could also go for 5W40! Or, if someone wants to spend a lot of money, they can buy oil from racing, where a 5-liter bottle costs over 50 euros! When you're at the auto parts stores and look at the oil shelf, it's not unthinkable that you might even find oil from space research there! Who can possibly know which of the 20-30 oil types is best suited for their engine!And then there's a whole range of oil additives, where some are better than others! My concern is that chip tuning puts more strain on the engine, exposing it to greater wear and tear, which could ultimately significantly shorten the engine's lifespan, depending on how it's driven. I want to compensate for this somewhat with better oil and/or an additive. For example, I made my old TD's life easier with Slick50! It's hard to judge, but I've generally had good experiences with it. I can't say how it affects the oil temperature, but I can imagine that this measure could also contribute to lowering it.

I am open to further suggestions!

Thank you very much!

Hi,

You mean 150°C in the oil pan, right? But it depends on the viscosity index, otherwise the oil film will tear.

Best regards, Rainer.

I'm very satisfied with the 10W-60 Castrol oil and I can only really...
report on it well (the lifter tick disappears very quickly).
Oil consumption, etc.). It originally had 0W oil --> then it started making a bit of noise.
consumes more oil. It's also supposedly not very good for the turbocharger bearings.
It's probably too thin.

Greetings, H-P.

Thank you! I'll probably try it out with that then! Is your TDI also chipped?

Regards, MR...

I used to have a module from KW-Systems installed for a while (approximately 20,000 km).
and I've now removed it. The constant jolting was incredibly unpleasant.
'point to. Also, I had the problem that it would sometimes...'
Trip canceled!

It doesn't belong here, but I just wanted to answer your question.

So, with the 10W from Castrol, I don't think you can go wrong with our TDI engines, especially since my sales representative always gives me 5 liters. he he.

Greetings, H-P.

The type of oil you need depends on the year your TDI was manufactured.
'If you have a car with fixed inspection intervals, such as 15,000 / 30,000 km, you can use engine oil that meets the VW specification 505 00, as indicated on the containers.'
'If the car is newer and the inspections are based on your driving style, the type of oil required will be different; I believe it's 503 00, but it's specified in the owner's manual. Oil that meets this standard is very expensive, and I wouldn't use anything else to avoid voiding the warranty.'

hi,
"I use Mobil 1 in my T4 (Transporter/Van). It's a 0W oil, which I've heard is best for the turbo. I don't have any problems with oil consumption, and I occasionally top it up by about an eighth of a liter, but I consider that perfectly normal."
Regarding the oil temperature, I can only smile. On the track with the G60, it easily reaches 150-160°C, but I just let it be. So far, everything is fine (using Castrol RS).

Hello Brobble,
Stupid question... how do you get the oil temperature onto your MFA? I have a '98 Passat and I can't figure it out.

Thank you and best regards.
Werner.

Your Passat is a newer model and doesn't really have much in common with the technology in the Golf3, Passat 35i, or Corrado! Unfortunately, I don't know if your MFA (Multi-Function Display) can display that information! I just keep pressing the 'Mode' button on the windshield washer lever until I get to the oil temperature display.

Regards, MR...

PS: There are no stupid questions, only stupid answers!

Hello Brobble.
I've also been using Slick 50 in my Passat TDI (1994 model) since I bought it in 1996.
I'll probably get another one soon, because my experiences have been consistently positive.
You can assume that this Teflon substance actually reduces the friction coefficient within the engine.
I noticed a quieter engine and lower fuel consumption in my Passat. Even during long, full-throttle drives, I don't exceed 95 degrees Celsius, if you can believe the gauge... (despite the chip from KW).
Ah yes: This year, with a Kamei roof box and fully loaded, I drove to Denmark and achieved 5.8 liters per 100km.

The most significant effect I observed was in my 1303, which had a 2.0-liter Porsche (914) engine. After using Slick50, the four carburetors had to be completely re-tuned because the idle speed increased from 900 to 1300 RPM.
In addition, Herbie consumes just a little over 10 liters on the road at a constant speed of 140 (travel speed }), while all other comparable engines consume 12-15 liters.
I am very confident in this additive...
There are also recently developed ceramic additives that are supposed to do the same thing, but I don't have any experience with them.

Best regards.
Sure, here is the translation of the text from German to English:

Hi, where can I find 'Slick 50'? Can it also be used in engines with common rail injection systems (PumpeDüse)?

Best regards,

Hello,

I used Slick 50 in my old 2E engine (GTI, 115 hp, 2.0L) for the exact reason of reducing oil temperature. However, it didn't do anything. It didn't lower the oil temperature when driving at full throttle (in fact, it was a few degrees higher), and it didn't affect fuel consumption.
In my opinion, a problem with the Slick50 available in Germany is that it's based on relatively cheap, conventional mineral oil (Slick 50 is essentially just a PTFE additive, or Teflon). This significantly diminishes the beneficial properties of the full synthetic motor oil being used.
In the US, there was once a product called Slick50 that was based on full synthetic oil (I believe it was even stated on the packaging that the base oil was Quaker State 5W-30). It was also only available as a bundle with 4 liters of Quaker State oil.

I also had a chip installed back then (from Kerscher, approximately +8 horsepower).
The oil temperature would consistently reach around 145-150° during extended periods of full throttle.

I switched from the usual 10W-40 semi-synthetic oil to a full-synthetic 5W-40 because full-synthetic oils are more stable at high temperatures. However, after a long period of full throttle driving, the oil pressure at idle was well below 1 bar. I then switched to Castrol RS 10W-60, and lo and behold, the oil pressure was always above 1 bar at high oil temperatures when idling, and I haven't exceeded 140°C since.

Now I have a Golf IV with 115 horsepower and a PD engine, which means I can only use oil that meets the 505.01 specification (which is only available as 5W-40). However, even after a long drive at full throttle, the maximum oil temperature is still a perfectly acceptable 120°C.

For a standard TDI engine without a PD (Pump Düse) injector system, using a full synthetic oil that meets the VW 505.00 specification is a good choice. I would recommend a 5W-40 viscosity. Based on my experience, Valvoline's 5W-40 full synthetic oil is the most affordable option (and is also available at ATU).
You don't need to worry about the oil temperature up to 130°C; VW states that oil temperatures up to 150°C are considered 'normal.'

Slick50 in the PD? Absolutely not.
