LongLife: Yes or no?

Hi fellow DIY enthusiasts!

Yes, I have used the search function. The following is what I found:

Other advantages of LongLife service oil include: lower fuel consumption, higher thermal stability of the oil. better cleaning properties and reduced wear.

That sounds like a glowing review of the LL service.

My car's display now shows "Service in 1800 km" – which means it's been 18,000 km since the last oil change. That oil change was done during the head gasket repair. I cannot say whether the service interval was reset or not (I didn't check ).
I drove about 3000 km of those 18000 km with a caravan (which means extreme loads). Otherwise, the car is mainly used for driving in rural areas (approximately 50 km, no highways).

My question, however, goes in a different direction:
Is it worth switching back to a fixed interval for the next service, considering I've already driven 3000 km with the extended "LongLife" interval, or should I stick with the "WIV" (variable interval) system? With the fixed interval, I have to buy such expensive oil .


The 3000km message appeared after a 700km campervan trip... since then, I've driven another 2000km .

Hi!

You need to calculate whether it's worthwhile based on the prices at your car dealership. The oil will certainly be cheaper if it doesn't have to meet the LL standard.
In the combined mode, the system calculates the average of your driving style (roughly similar to the average fuel consumption displayed by the MFA2). If you drive the car aggressively between service intervals, that will be factored in more heavily than if it happens shortly before the next service.

The WoWa route seems to have been very demanding on the engine, and you were driving a bit more 'relaxed' afterwards, which is why the value is currently increasing again.

I don't think it's worth it, because the workload is the same, and the only thing that becomes cheaper is the oil.

Generally, LL oil represents a compromise between fatigue resistance and the ability to incorporate carbon black. Achieving this balance is challenging. We won't know for sure which is better until some time has passed and the first LL-TDIs have aged. Thinner oil is generally better because it's easier and faster to pump, allowing it to reach critical areas in the cylinder head more quickly.

Hi,

A good basis for making a decision about whether to use longlife oil or not can often be found here:

That's exactly what my question was aimed at.
What about potential long-term effects?

So, you also mean: don't worry about every penny and take advantage of the LL interval. Even if the advantage is only a few kilometers.

I know, but my primary concern wasn't the cost (as mentioned above).


My decision about whether or not to pursue LL (likely "LL.B." or a similar legal degree) was made a long time ago. I just wanted to put this out there for discussion and see what others think, without wanting my decision to be influenced by it.http://www.autoservicepraxis.de/wiv-rechner/start.php{MARKER}

Okay, 0W30 or 0W40 oils are also available without the Longlife specification. Each person has to decide for themselves whether or not to use Longlife oil. It's more critical with gasoline engines. We have a Golf 4 1.6 16V at the shop that has been using Longlife oil so far. The car now has 51,000 km on it, the engine oil is almost empty, and it smells strongly of gasoline. I would have already had an oil change done, but the boss says the service is only due at 60,000 km. Well, with my 1Z, I'm glad the question doesn't arise, since it doesn't have LL (Long Life) service.

Best regards, WarLord.

I found BP LL 2 - 0W-30 oil online for €8.90 including shipping.

The price isn't bad, but in my case, it's still too expensive. As a licensed driver (motorsport), I have the opportunity to buy oil directly from various manufacturers (including once a year for my private car). I recently paid €5.50 per liter for BP LL2 oil. Therefore, for me, the question of whether to use LL (low-saps) oil definitely isn't dependent on the oil price. Okay, I'm going to do an LL service.

Hi fellow mechanics,

Since it's been another year since the last service, I wanted to provide an update.
After another 24,000 km, the service computer still shows no warning signs... so it's definitely possible to achieve long service intervals.
For a high-mileage driver, doubling the normal service interval can definitely be a worthwhile investment.

Absolutely! / I completely agree! / Couldn't agree more!

My first long-life service was in April at 37,500 km, and since then I've driven another 24,000 km, but I haven't received any long-life service warnings yet. If it now triggers a service warning in 3,000 km, it would be my second one. Service is not due until 64,500 km.
I am very satisfied with this, as it represents a significant saving compared to service intervals of 15,000 miles.

The inspection costs:

135.85 € for the LL service.
56.76 € for oil purchased separately.
16.77 for an indoor air filter purchased independently.
5.80 € Waste oil disposal.
10.15 € for a VW oil filter and screw.
Total cost: €225.33

For comparison, the cost of a 15,000-mile service for my old Ford Focus and Mondeo diesel company cars was: €273.54.

Even though the supposedly possible 50,000 km mileage was far from being reached, I can't really complain about the VW LongLife service interval when comparing it to other options.

Best regards, Marcus.

Please refer to the oil analyses for further information.

Therefore, the permissible limits should not be extended as much as the manufacturer intends.
OR use a finer filter (and still change the oil).

'However, it's still worth it for me, as the oil consumption is negligible, and long-life oil still costs less on the open market than non-long-life oil from the dealership.'

I still feel uneasy about the idea of leaving the oil in the engine for up to 50,000 km. Just thinking about the amount of dirt that accumulates is enough to make me uncomfortable. I much prefer spending a Saturday in the garage every 15,000 km, regardless of the fact that I don't pay for the oil. It only costs me the filter and some small parts. Furthermore, after the change, I always felt that the engines were running better.

That's why I'm saying: if it's going to be that long, then use a fine filter.

The oil is still in good condition after the running time. There are still plenty of additives left, and even the dirt-carrying capacity is still 100%. The only thing that accumulates is dust and grime.

Only dust and lint accumulate endlessly...


Hmm, I seem to recall that my soot level was significantly lower... PD rulez!

Let's see if the silicon content can be reduced by changing the air filter more frequently... *it would be funny if it worked*.

Hello,

I'm planning to replace my LL factory-fill engine oil in August (around that time, the AI system will likely start prompting me for a service) and switch to fixed intervals using the 505.01 specification.

Now I have about three-quarters of a liter of LL 506.01 left over = the remaining amount from the free can that came with the purchase of the new car.

Is there anything wrong with adding a 505.01 oil additive during an oil change to shift the oil's viscosity slightly towards 0W for the winter and improve its long-term lubrication properties?

Or is it possible that the oil chemistry of specifications 505.01 and 506.01 is incompatible?

Hi Ulf,

Which oil with the 505 01 specification are you considering?

Regards,
Sure, here is the translation of the text from German to English:

the remaining, unused portion from the free can given when buying a new car

That means you only added 0.25 liters after driving approximately 14,000 kilometers?
"No bad value, I had already consumed about 1 liter at that point, and today, with almost 47,000 km total, I've used 1.75 liters..."

Generally, the mixability of 50501 / 50601 should not be a problem, as VW even officially allows, on a one-time basis, adding 0.5 liters of 50501 to a 50601 filling, without losing the LL (Longlife) property. I think the 3/4 liter size would also be suitable, especially for shorter operating times.
