Hi Guy's,
I've been looking to change my oil to Motul or AMSOIL. After calling around the GTA to try to find one of these I have found Motul in a european shop just down the street as well as Don Valley VW.
the dealer is pushing Motul specific 505.01 as is is the stuff they use normally.
Now my question is, is anyone out there using the 505.01 in their 1.8T?
The shop down the street has Motul 8100, which from what I tell and have been told it the 8100 doesn't meet the spec as well as the specific 505.01.
the Dealer price is cheaper too but that is not what's important for me.
Any info whould be great.
Thanks in advance.

505.01 oil is specifically for the TDI PD engines.
VW Canada sent me a TSB stating that I have to use 502.00 oil in the Passat 1.8T to avoid sludge build-up.
Motul 8100 X-cess 5W-40 and 8100 Ester E-Tech 0W-40 meet VW 502.00 specs.
Here's what the Motul site says about the 505.01:
Motul 505.01 5W-40
Specially designed for cars powered by Volkswagen Turbo Diesel engine (unit injector).
Suitable for all types of VW gasoline (except VW 502.00) or Diesel engines, using leaded or unleaded gasoline and Diesel fuel.

505.01 is not synthetic oil. It was designed for new PD TDI engines.
you need 502.00 for your 1.8T.
Bring your car to my shop. I carry most synthetic oils that match your needs.

The 505.01 specification is synthetic. As an example, Volkswagen part number G 052 167 02 is marketed as 505.01 and it also exceeds 502.00 standards.
Have a look at the list of approved oils (link below) as published by Volkswagen. There are a number of oils that meet both 505.01 and 502.00 standards.

I use olive oil in my rides. Extra virgin of course. Nothing but the best.

Once upon a time a van came into my friends shop because it just quit running...

Long story short. Don't top up your oil with vegetable oil....

Not really. Castrol txt 505.01 is a hydra-crack oil and not a full synthetic. If you want a full synthetic thats VW approved, its time to run VW506.01. I am pretty sure alot of VW505.01 are still based upon Group III oils. Only a GroupIV PAO oil is considered a truely full synthetic..

School me on synthetics a little here. Castrol's website says that TXT 505.01 is made from synthetic base stock. I thought that meant that it was a full synthetic - maybe I'm wrong.

Other than AMSOIL European Car formula I have not seen a 505.01 that is a group IV or V. AMSOIL is not on VW approved list.
Lubromoly says it on the bottle that 505.01 is semi synthetic which means hydrocracked group 3. ELF DID and Motul 505.01 are both group 3. As you said 506.01 is a mixture of group IV and V with 10%-20% Group III as addetive carrier depending on the brand.

Castrol considers group III as synthetic.

Re: (Don R)

505.00 rating is for diesel TDI . for your 1.8T you should look for 502.00 Most 505.00 meet 502.00 rating.
1.8T are known to build up sludge. Look for at least a group IV 5w40 synthetic and avoid all group III oils.
My personal prefrence is AMSOIL 5W40, Motul 8100 5W40 and Lubromoly 5W40.

I used to use Motul 300V unitl it was harder to get, thus more expensive then I tried Castrol Syntec 5W-50 and now M1 5W-50 with great results. The following results are on a daily driven 350whp 1.8T built motor .

Can you explain the mileage the car?
you have one test done at 18K then another one at 75K and third one at 23K?

The 75K miles was tested on Motul 300V on stock internals equipped with a GT28R at the time. Prior to that I was using Motul 8100 5W-40 which I also liked http://****************.com/smile/emthup.gif
The 18K was on Castrol Syntec 5W-50 Built motor equipped with a GT2871R Setup.
The 23K was my last test Mobil 1 5W-50 built motor equipped with a GT3076R setup.
I just changed my oil recently and forgot to get a sample for testing

Re: (Don R)

Rebuilt engine tend to show higher Iron content. The reduction in Iron on the second UOA is to be expected. In fact there should have been a larger reduction taking in to consideration that you only put 5K on the oil.
V300 is great oil probably the best oil money can buy for "racing" V300 wont have any advantage over 8100 on a street car.
Try AMSOIL European car formula or Lubromoly 10W60 for your next oil change and see if the results are any different. If you are not racing your car you can extend your oil changes to 10,000KM. As long as you are using a group IV or V oil 10K wont a problem at all.
Keep an eye on TBN after 10K OCI and you should be fine.
You are on the right track. Keep on sampling the oil at least once a year. There are too many people who spend big $ on modification but skimp over motor oil.

Thanks for the input http://****************.com/smile/emthup.gif I don't race the car just a fun machine to do some R&D on

Would the 60W oil be a little heavy? I'm sure oil pressure would increase and too much of that would be detrimental to the turbo...just a thought

The reason I suggested 10W60 is that you liked Motul V300 which is a race spec oil. 10W60 can save your engine on the track but wont provide much of protection on street.

My Volkswagen dealer (Volkswagen Richmond Hill) uses Motul oil as their standard everyday oil for all oil changes. Motul makes different varieties of oils that meet all the VW 50x.xx specifications.
Attached is a PDF attached containing a list of all oils (from all manufacturers) that meet VW 50x.xx specifications. Also a picture of my car in the dealership last week - there is something in that picture that suggests my VW dealer likes Motul lubricants, but I can't quite put my finger on it...
