506.01 is worth the extra cost

03_01_TDI · Jan 16, 2005

I am looking at the 30 weight oil to improve the fuel economy. But am unsure if the $$$$$$ 506.01 is worth the extra cost.

6qt Motul 506.01 with shipping is $75.00 plus filter

6qts Mobil 1 505.00 from local store $30.00 plus oem filter-38.00 per 10k miles or $76.00 per 20k miles.

So as long as I can get 20k oil changes vs 10k oil changes the 506.01 is worth it. Plus if the 506.01 oil improves the fuel economy then I'd come out on the positive side. I could even pay for oil anaylis

Amsoil has some 5w30 and 0w30 oils that are about 5.00 per qt less. which would might be perfect for non-pd cars.

IMO no - not for an ALH (pre-PD) engine. There are so many stories of people driving mega miles with good 505.00 synthetics and extended drain intervals that I don't think the cost of 506.01 is justifyable in a non-PD.

in a PD, maybe. on paper 506.01 looks amazing - probably superior to virually every other oil. but only time and testing will tell if it's reduces wear and increases fuel economy enough to justify it over 505.01. 505.01 is very good oil too.

jddaigle · Jan 17, 2005

I'd say it's only worth it if it allows for 20,000mi drain intervals. And I'm not about to test that in my PD until I see some solid evidence that running 506.01 with 20k intervals doesn't result in unacceptable cam wear.

This of course assumes that you don't have a car with a flexible service interval sensor in the sump that will tell you when it's time to change the oil. Since my car has no such sensor I'll err on the side of caution & stick with 505.01 every 10k.

Amsoil has some 5w30 and 0w30 oils that are about 5.00 per qt less. which would might be perfect for non-pd cars.

I would be very cautious and not confuse this issue. The 506.01 is specifically designed for extended drain intervals. Most other oils are not.

The 506.01 is a unique animal.

d2305 · Jan 17, 2005

I wonder just how unique the 506.01 in as compaired to say Mobil 1 0W30. I noticed that the 506.01 had boron and molybdnum which the 505.01 dosn't have.

03_01_TDI · Jan 18, 2005

The math adds up. So next oil change I'll do the switch to 506.01. I'll do the oil testing at 10k and 20k and report back.

Where do you guys dream this stuff up

Mobil 1 0W30 is not even approved for use in street vehicles nor does it carry a single API rating. It's not intended for anything but "racing applications".

How could this product EVER be considered for use in a PD, which is the only thing being discussed in this thread, let alone ANY TDi or diesel engine, d2305?

dieseldorf · Jan 18, 2005

Also, the 506.01 carries a ACEA B5 rating:

A5/B5 Stable, stay-in-grade oil intended for use at extended drain intervals in high performance gasoline and car + light van diesel engines designed to be capable of using low-friction, low-viscosity oils with a High temperature/High shear (HT/HS) rate viscosity of 2.9 to 3.5 mPa.

These oils may be unsuitable for use in some engines. Consult owner manual or handbook if in doubt.

d2305 · Jan 18, 2005

I'm just not convinced that 506.01 is that unique as compared to other synthetic extended drain oils, and not worth $15/L. I could be wrong, and time will tell. API ratings have nothing to do with PDs either. "Mobil 1 Racing 0W-30 is a proprietary blend of high-performance synthetic basestocks fortified with SuperSyn anti-wear technology. This advanced protection is engineered to deliver maximum horsepower.

Has boosted levels of anti-wear protection -- well beyond those of ordinary automotive oils -- to help protect engines even during grueling racing applications.
Maximizes power output by reducing internal friction.
Has outstanding shear stability and a robust additive package to help reduce oil breakdown and help extend engine life, even under the most extreme conditions.
Compared to conventional racing oils and higher-viscosity synthetic motor oils, it provides faster flow to critical engine parts at low temperatures
Delivers exceptional high-temperature protection, even at temperatures up to 400 degrees F (204 C)" Sounds like it may keep a PD engine together, but it not approved by VW. Neither is 506.01 in North America.

dieseldorf · Jan 18, 2005

Why are you mentioning Mobil1 0W30? Where does it fit in to the big picture?

d2305 · Jan 18, 2005

I think that 506.01 costs too much, and not worth the extra money. However, I would use it, or Mobil 1 0W30, if I lived where it gets below 0*F.

dieseldorf · Jan 18, 2005

that's cool, I guess it's all relative. Do you have a PD?

d2305 · Jan 18, 2005

Yes, an 04 NB 15k. I'm thinking about changing the oil now as I have Motul 505.01 in it, and as we know it's just a blend. It's cold here 50* now.

dieseldorf · Jan 18, 2005

So you're going to use a non-compliant oil in your PD? It's fine if you like, I'm just trying to keep track.

dieseldorf · Jan 18, 2005

Re: 506.01 is worth the extra cost ?

Mobil 1 does have another 0W30 oil (meets B5 criteria) that's intended for use in street cars....not the product that you're quoting above. It may be fairly new. I've never seen it in a retail outlet.

tammytroot · Jan 18, 2005

Re: 506.01 is worth the extra cost ?

I have been using 506.01 for about two years. My VW handbook does not state 10k,20k or 30k as the life of the oil. What it does say is that this oil must be as PART of the VW Long Life Service which will be determined by a sensor in the car but adds the rider that service intervals should not exceed 2 years or 30k miles

dieseldorf · Jan 18, 2005

...that service intervals should not exceed 2 years or 30k miles

You're making complete sense!

I'm just not convinced that 506.01 is that unique as compared to other synthetic extended drain oils, and not worth $15/L.

All you have to do is look at the market for VW-approved oils in Europe, and the laws of supply and demand in a free market perfectly illustrate that there IS something unique about the 506.01 formulation. If you do a search, you'll find the list of VW-approved 506.01 oils (or just wait 15 minutes and dieseldorf will post it

).

There are MANY manufacturers, and the market for 506.01 oil in europe is significant. There are lots of PDs on the road over there. If the 506.01 wasn't really worth $15/L, at least some of these companies would be selling it for less. There's no global 506.01 pricing conspiracy when there are so many manufacturers involved.

Wow, make that 4 minutes.

Dieseldorf, you are slowing down in your old age!

dieseldorf · Jan 20, 2005

...could be or more likely the newbies are taking their toll

d2305 · Jan 20, 2005

Could be that there are few blenders of the oil, and others put their name on the jug.

Pelican18TQA4 · Jan 21, 2005

So where might one find a 506.01 oil in the U.S.??

dieseldorf · Jan 21, 2005

I thought someone said IMPEX is offering the Motul version (call Jerry X106 for all the details) or Scott at SabreChem for the ELF product line.

03_01_TDI · Jan 21, 2005

The math is simple. 10k oil changes or 20k+ oil changes PLUS IMPROVED mpg.

I just love it when "old" guys are stuck in this "must change oil every 3k miles". In germany it has been common for many years to have 6k-10k oil changes. This 506.01 oil has been TESTED, proven, and made by numerous companies.

My only real concern is that we have the high sulfer fuel in the US verse low sulfer fuel. But I've got a lead on some diesel for 1.35 a gallon and then I can afford to buy some b100 and make my own b20.

tammytroot · Jan 22, 2005

Purchased a litre of Castrol SLX Longlife II this morning for my Golf

PD TDi. It cost £9.50 (exVAT). The guy behind the VW parts counter said VW were about to bring out their own 506.01 (still made by Castrol) but he recons it will be half the price.

506.01 is worth the extra cost
