Best ESP For Audi 505 Spec 3.0T's ?

[edyvw]

My '14, '17 and '18 Audis absolutely did come with that spec, even if it's an old spec. I think it still does. I'm not saying that there are not better oils today....This is from an Audi site.

Audi Q5 Oil Specifications​

Audi provides detailed specifications for the lubricants to be used in its vehicles. Using the proper oil in your Audi Q5 is vital for optimal operation. It's best to use a fully synthetic motor oil in your Audi Q5. This means that the oil doesn't contain mineral oil, which can damage the engine.

Audi specifies several viscosity grades for the Q5: 0W-30, 0W-40, 5W-30, and 5W-40, which meet the VW 502.00, VW 505.00, or VW 505.01 requirements. The first digit followed by a W indicates the performance of the oil in winter conditions, while the subsequent number indicates the oil viscosity, with lower numbers denoting thinner oil:

• Oil type: Fully Synthetic.
• Viscosity grades: 0W-30, 0W-40, 5W-30, and 5W-40.
• Specifications: VW 502.00, VW 505.00, and VW 505.01.

The oil must adhere to VW 502.00, VW 505.00, or VW 505.01 specifications. These stringent standards ensure that the oil meets Audi's performance and protection requirements for its engines and that your vehicle remains under warranty.

Well, as I said, VW is known to recommend approvals that don’t make any sense, like in this case 505.01 which is approval specific to PD engines.
Since your car is out of warranty, above mentioned X4 is good as it is VW511.00 approved, which is W40 version of VW504.00.

I have owned 2 3.0T's. The first one was previously abused and overheated the first day I drove it, burned oil like crazy. The second came came off a lease from a doctor, low miles and so clean.

One thing you need know about these engines is that they are powerful, and run HOT.

VW502/505 is the standard, keep it. I put VW504 M1 ESP 5w30 in the abused engine, as an experiment, and it burned oil much quicker than any VW502.

I have a recent oil analysis I will try to upload. Motul xcess gen2 5w40 SN. I did a double change to rid whatever mixture was in before, and start fresh. The oil tech didn't think it was necessary, but he was surprised how dirty the fresh oil was when it came out minutes later. This was talked about by Lake Speed jr. and I now believe is very important.

Don't bounce around from one oil to the next, mixing standards and formulas could increase wear actually. I was guilty of that, we all are. Find one you're confident in, and stick with it, stick with the standard SN or SP, and change it often.

M1 ESP X4 0w40 looks like premium stuff, but lot of API SP have very similar properties, they share the same additive packs. I wouldn't stress over getting the most expensive one on the market

These engines have been around for a while, owners have gone 200-300k miles with the old 5w40 SN formula no problems. Especially tuned, like a stage 2 single pulley, they all recommend 5w40. But if you really want to know what's going on, get a few oil kits. See exactly what your engine is saying.

I had some fuel dilution, hopefully it was due to the very cold winter starts and short trips, we will see on the next report. But as far as wear metals go, there isn't much room for improvement, the Motul 5w40 is doing it's job and I plan on going a little bit further with it this time.

If you're not tuned, grab any Euro 5w40 and call it a day.

Besides always wanting the "best" oil, it all started with a magazine report that the '17 Q5 3.0 was reported to have "major engine problems". So now it was more important to have the best oil and shorter OCIs. I really don't need the "0" but the ESP X4 comes that way. At first I always used the Castrol 5-40 (?) that was recommended by Audi and the car even came with a brochure stating that it was refined an extra step, it looked like golden honey. Then, on this forum I read that some did not think that it was that special and that there were better oils. After Audi discontinued their relationship with Castrol the new, black bottle VW oil was not as well know at the time, hence my search for the Holy Grail of oils. I don't know much about the differences that make one spec required for certain model years and engines so that leaves me to try and get better educated options here. I bought the 0-40 X4 due to some comments here and my own limited research (I use the ESP 507 in my TDI) on it, hope it doesn't cause any damage. Ideally a heavier oil would benefit the car in the hot summer weather but I'm not sure of that either, I remember when researching the old Castrol GC, which I still have, that it was better at hot weather protection than some of the 5W oils. Thanks

Oh you won't hurt your engine, that's the best oil around. I missed the part where you said you could get a deal on it, go for it. I wish I could even find it on the shelves. cheers.

ESP X4 is great oil.
It won't cause any damage. It has the newest VW approval, VW511.00, which is designed specifically for RS6 and some Porsche engines.
Your engine basically needs HTHS higher than 3.5cP. The grade is really irrelevant in European engines. VW uses grades as average folks understand grades better. Using HTHS would be a bit complicated. A minimum HTHS of 3.5 comes in 0W30, 5W30, 0W40, and 5W40 (and usually max out at 4cP in those grades with approvals).
You could easily use ESP 0/5W30 in that engine as VW504.00/507.00 has a minimum HTHS of 3.5. Lower HTHS also means less heat and less rsistance=better performance.

Can you order it online or at a store? My AZ had to get it in from a warehouse.

The 5/30 was my first choice, as I said before I don't really need a "0" and I'm a little concerned about it in the very hot weather. I might end up using one in the very hot and the other in the very cold.

There is no concern about that whatsoever. Lots of confusion about winter ratings, what they mean and what they do not mean.

For the most part grade is irrelevant here as edyvw has already noted.

I would not seek out and pay extra for 511 00 when 504 00 is perfectly acceptable and available at Walmart for a very good price.

X4 is just plain better than the 5W-30. 3.8 HTHS and used in Porsche Cup cars.

There should not be concern.
0W or 5W is just pumpability of oil at -30 (5W) or -35(0W). How they perform (HTHS) at 150c is different matter. Many 0W oils are more stout (for the lack of better word) than 5W oils. You mentioned Castrol 5W40. In Cadtrol line up it is positioned below 0W30/40. It is all about base stocks (in Castrol case 0W30/40 have up to 50% PAO, while 5W40 is just Group III).
Second, your cooling system is responsible to maintain proper internal temperature. As I mention often, ambient heat is not an issue as much as altitude. That is because at altitude cooling system just can’t transfer heat as efficiently bcs. Air density. So, as long as your cooling system maintains operating temperature, everything is fine, whether that is 100 degrees or 20 degrees. Difference will be in amount of time oil needs to reach operating temperature. That is where 0/5W30 are better. In cold weather if engine needs bit more time to reach operating temperature or cannot reach one, those oils will have bit lower viscosity and with that better flow. The golden rule of lubrication is: “as thin as possible, as thick as necessary.”
