Hi guys. In a quandy here, Hope you can help bail me out.
I started my oil change on my 2005 TDI (BEW engine code) yesterday evening and all was going great until I went to refill the crank case. I ordered two five liter jugs of what I thought was liqui moly 505.1 approved oil. Turns out it was the synthetic premium 505.0 approved.
Anyway, I can t find the liqui moly diesel high tech 5/40 505.1 approved oil locally but I did find the Liqui Moly 5/40 Top Tec 4100 505.1 approved oil.
The approval ratings are correct for the Top Tec 4100 so what is the difference between the two?
Thanks for any and all help.

The high tech is the diesel labeled stuff. It says 505.1 approved.

I will try and take a picture of the jug showing approval ratings.

Diesel High Tech is 505.01.

Synthoil High Tech (which you have) is 505.00 only.

Your immediate problem is finding it locally to finish your change. Use the Top Tec.

Or go to any Theisens or Tractor supply or Fleet and Farm and pick up some Mobil Delvac 1 ESP 5w40. Not 505.01 but alota PD owners run it. Its great oil. Atleast once a year Pepboys has it on sale and with Mobil rebates its like $9 a gallon. I run it.

I can be a bit dislexic at times. Ill rephrase my question.
I bought the premium synthetic 505.00 oil thinking it was in fact the High Tech 505.1 PD approved oil. Just before refilling my crank case I noticed my mistake.
Unfortunately I could not find the stuff I normally use (Diesel High Tech 5/40 505.1 approved oil).
The parts house has the Top Tec 4100 which states it is 505.1 approved for the PD engine.
So my question is what is the difference between the Diesel High Tech 5-40 505.1 and the Top Tec 4100 505.1 approved oil?

Top Tec is a full Group III synthetic.

High Tech is a Group III synthetic / mineral blend (semi-synthetic).

So the full synthetic is best for the heat produced by the turbo but mineral is better for lubrication right? Or do I have that backwards?
Either way would the semi syn blend be better as compared to the Top Tec 4100?

The additives used in the formulation are the keys to the different specs (505.00 vs 505.01), specifically around wear, ash content, etc.

Synthetic is more about heat, cold flow, etc. The purpose for Blends is more about pricing (lower), with some of the benefits of synthetic.

Personally, I'd use the Top Tec. I use Top Tec 4200 (507.00) in mine.

Bobistheoilguy.com is an excellent resource for all things oil. I'm not an expert, but you'll find several folks on there who are.

My mistake. I was asking the difference between the
Diesel High Tech 5-40 (505.1 approval) and the Top Tec 4100.
From what I can tell they are both semi synthetic.

No, the Liqui Moly product site shows them as different, and listed as such.

Diesel High Tech = Semi Synthetic (Blend)

Top Tec 4100 = Synthetic Technology (Hydrocracked Group III Synthetic)

Hi Folks, my question is related but a bit peripheral. Does it matter if different brand oils are used in the life of a newer (2010) TDI as long as all the oil used meets the VW 507 standard? i've got a 2010 Jetta TDI bought in Oct 2014 certified pre-owned. All prior service done at the dealer where i bought the car. When my first oil change came up i went with Liqui Moly Top Tec 4200, which meets the required VW 507.00 standard. i looked & found multiple versions of Castrol Edge but NOT the one that meets the standard. So i went with the Liqui Moly but paid a pretty high price at a parts store where i do well for parts otherwise. With the receipt of my VW monopoly money i'm going back to the dealer to validate the $$ cards & will have the 80K service done. Their occasional advertised specials for oil changes state that they use the Castrol VW 507.00 approved oil. i could buy the necessary Liqui Moly (which i now find cheaper at ID Parts) & have them use that if it makes a difference but since they did service on the car from new, it's likely it's had the Castrol most of its life so it's already had one change in the oil used. The Castrol is markedly more expensive than the Liqui Moly Top Tec 4200 & i have no idea if either one is better than the other. i'm guessing that as long as the oil meets the 507 standard, it should be Ok but i'm definitely not a mechanic nor a chem engineer. i just wonder what any of you think--am i just being nuts? Thanks.

Doesn't matter at all.

It may not matter but for what its worth when I ran the castrol around 7-8k the engine became noticecably louder. Since using the top tec 4200 I do not notice the increased noise towards the end of the 10k interval.

The consensus from the "oil people" I respect on this forum is that the requirements to be considered a 507.00 oil are so strict that one brand is as good as the next. They are all pretty pricey compared to other oils, but that appears to go hand in hand with the low-SAPS (sintered ash) levels that make them healthy for your DPF. It's encouraging that some brands are coming down in price. Liqui Moly is a very respected German brand, I wouldn't hesitate to use it.
