Am I just dim or is there no forum search facility? This must have been discussed many times.
Anyway what grade oil do people reckon for 3.0Tdi engine life?
And Semi or Full (always an emotive subject)
Thanks
 
5w40 fully synth Castrol :icon thumright:

Search should be top right I think, it's not the best though so I usually Google what I want with Audi-Sport in it for example "Audi-Sport b7 3.0tdi oil".
 
Thanks for the reply, I did find the search and agree it's not a very precise tool.

I'm glad you say 5w40 because ECP & GSF both give 5w30 or even 0w30 which makes my toes curl.
I'm buying into the conspiracy theory that lower visc. oils are all about hitting efficiency targets with disregard to engine life.
 
The main things you have to be concerned with when it comes to oil is the VW specs they meet (especially with diesels, mine in particular has some annoying 501.01 or something like that when I could only find oil I wanted without the .01), some people here (one person in particular comes to mind who I'm supprised hasn't voiced his opinion yet) think that the higher the VW spec the better the oil but I'm with you in that the viscosity is important which is why I would run a 0w40 but unfortunately the majority of 0w's don't meet the specs for the car which is why I go 5w40.
 
I emailed the visc. question to OpieOils, they replied:

"Unless it's heavily modified, so the oil runs hotter than standard, then there is no benefit in the thicker oil. Thicker oil will flow slower and reduce protection, so I would stick with the 5w-30, unless modified."

The VAG spec(s) that I'm being offered by Opie/GSF/ECP are 504.00 & 507.00 It looks like 507 is the low SAPS version but current oils meet both.
Where would I check those specs? Handbook?

Simply not entirely true , the cross over between grades is a gnats whisker and between the two Castrol Edge 30 & 40 is just that so they can be thought of as a thin 40 and thick 30 .
 
Grades in my handbook are not quite what the online sellers are specifying.
Handbook for short servicing gives 505.00/505.01/507.00 The 507 is the only one listed for DPF cars, which mine isn't.
When I search 505.00 on eBay I'm getting more hits for 5w40 than 5w30, on 20l drums at least.
There's a Triple QX fully synth 5w40 to 505.00 in 20lts

Speak of the devil :playful:

:blahblah1:

Basically @piglet14 either 5w40 or 5w30 is fine, I prefer 40 due to the higher heat rating but so long as either meets the specs VW specifies either is fine. I also use Castrol... well because Castrol :playful: Quantum is a cheaper version of oil which VW/Audi uses if you like.
 
Are you intimating that VAG oil is re-badged Quantum?
So does the visc. really come down to type of driving, ie. hard/high speed =40, shorter less demanding =30 ??
 
Quantum is what VW, Audi and the majority of VAG service places etc use, you can basically go to a VW/Audi place to get the oil and that's most likely what you'll get. No idea on the current ties but I know it used to be made by the same guys who made Castrol so everyone used to say it was a cheaper version of the same.

Basically the way the numbers work is you want the lowest first and highest second that you can get... well that's my opinion anyway, theirs more to it than that just make sure it meets the specs really and it'll be golden :icon thumright:
 
5w40 Vag spec for me. 140k on my engine so a slightly thicker oil benefits it.

I normally use fuchs titan supersyn

I wouldn't even call it slightly thicker , bigger difference when cold when you don't need it to be thicker and a clear circulation and mpg basher despite being the same 5W .

The 5W30 also has the benefit of being higher quality due to it's basestocks and additive package.

505.01 Vs 507.00...

They are same when cold. both 5W
The higher number is when hot. 40 being thicker than 30.

The oil viscosity has nothing to with quality.

First point incorrect , second totally correct , hence a 30 grade can be higher quality .

5W40 Castrol Edge 505.01
40°C , 75 centiStokes
100°C , 13 centiStokes


5W30 Castrol Edge 507.00
40°C , 66 centiStokes
100°C , 11.6 centiStokes


If cold info was available there would be an even greater difference , so 5W isn't what you think it is , like a grade , it has a range !

The grade is qualified at 100°C hense the difference is so small .
 
So basically the 5w40 is slightly thicker cold (not that it matters) and hot making it great for 3.0 tdi or any other high mileage or tuned engine.
:racer:

5w is the cold rating so can't be much if anything in it, like I say I'd have 0w if I could find a 0w40 oil that was a decent brand and met the specs of my car.
 
That's it Jake contrary to logic or belief there is a significant difference even at 40C .

There's no cold data sheet info but the difference would be greater than 9 centiStokes at 40 at cold .


1.4 or 1 centiStoke at 100C with some as a 507.00 are often 12 isn't thick enough to make a difference you need to go at least 14 for a 40 grade or use a 5W40 ester racing marketed oil to benefit from any prolonged high temp running such as track or Autobhan , or oil consumption issue .
 
Specs are going backwards as only 505.00 and non PD .

505.01 better ,
507.00 best .
 
505.01 Long service interval(I think)
507.00 Low SAPS
Better, best? Or just different criteria.

And is 0w40 'Fuel economy' at the expense of wear protection, deposit build up and seal degradation?
 
505.00 old non PD diesel spec , probably Group 3 oil basestock , group 3 is really a severely hydrocracked mineral oil .


505.01 as above but a PD spec now due to extra ZDDP anti wear additive to protect PD camshaft narrow lobes .
Group 3 + extra ZDDP .


507.00 , PD , LongLife by way of extra additive package concentration
( more detergents and dispersants ) low Saps C3 by reducing ZDDP it's the phosphorus in particular that leaves the ash and to compensate for loss of anti wear higher basestock groups 4 and 5 ( proper synthetics ) are also in the mix , top group 5 is ester and used in the expensive ester racing marketed oils all together the blend gives a more complete oil able to fulfil better oil performance perameters.
Reduced ZDDP , Groups 3 , 4 & 5 + extra additive package concentration .


505.00 Vs 505.01 Vs 507.00

2018 06 22 174643



504.00 507.00 can be thought of as a universal 5W30 oil , petrol , diesel , fixed , LongLife , non PD , PD , common rail it will do it all and better than other manufacturer specs .
 
May as well use the better oil which has come along since the handbook was printed. Diesels neither produce the same heat nor high revs as a tuned, high-revving petrol engine
 
So it is.
So then are all 507 spec. oils created equal?
Not really a brand name type of person, I shop at Aldi and dress only in Primark.
Vtech £54/20l
Quantum 20l cube £90
Castrol edge 20l £157
 
Yes a spec is a spec regardless of manufacturer .

The only packaging difference is if VW approval was sought and gained at great cost for submitting .

A marketing choice as approval will command a higher price .

The lowest price approved 507.00 is VW's own Quantum LongLife III made by Fuchs .
 
Finally got round to buying some.
Bewildered by online choice ranging from questionable quality/source to overpriced brand marketing, I actually physically travelled to TPS (only because I was passing)
Came out with a 20l cube (wine bladder) of 507 Quantum for £65 inc. Half the price of the brand names and if it came out of TPS it should be right.

Oil is always a hot topic on any forum and so it should be...

Will be doing my first oil change on my non-dpf BKN engine this weekend and I've picked up 10 Litres of Quantum LL3 at a price of £44.95 delivered :)

With a new Bosch Oil filter that's an oil change all in for circa £50, with around 2 Litres left for top ups on both my A4 and the TFSI Q3.

Happy :)
 
Easy to overfill I found, next time I'll stop short at 7.5l and add until it's right on the dip stick.
 
Carried out this morning satisfactorily :) Filled to 7.5L and ran the engine until warm, it then took the extra 0.5L.

I found the drained oil to be extremely thin, but not sure what was used in the last service! :smirk:
