No, they will perform equally well in your PD. T6 is one of the best API 5w40s you can find.VWBeamer said:I checked the cam and lifters before buying. They "appear good".
Think TDT is better?
Because of price and quality, I have been using T6 in all our non-TDI cars.Bob_Fout said:No, they will perform equally well in your PD. T6 is one of the best API 5w40s you can find.

LOL!!!!!Drivbiwire said:Never mind the 5K oil changes you're gonna be changing the cam and lifters, wrong oil!
Damage is done, start saving for the repairs, cost is approx $2K worth of damage.
After you make the repairs, start using the Mobil 1 Turbo Diesel truck 5w40, to date I can say that it has shown the best wear rates even when compared to the VW approved oils ie VW 505.01 which your engine requires.
Here is the damage you will have under you valve cover:
Yep, me to, I've got a buddy that bought a Jetta 2006 PD and he hasn't used the right oil in it yet. I would also hate to guess how many different oils he has used in that thing. He's got almost 200K on it now and the cam and lifters are fine.Blue02JettaTDI said:LOL!!!!!
Use what you want, Ive seen cams from PD motors using 15w-40 dino oil that look new with 170k on them.
Way to fail.Blue02JettaTDI said:I do 5-6k oil changes. Theyre cheap and easy to do.
And three times the wear rates on a car that cannot afford them.Blue02JettaTDI said:I do 5-6k oil changes. Theyre cheap and easy to do.
Detergents and dispersents in the context of oils should not be completely lumped in together especially with long drain oils.danham said:Politics, sex, motor oil: the three topics most likely to yield nonsense and bad advice on the Interwebs? [g]
Just a quick comment: "detergent" oil does not, contrary to popular belief, contain dishwashing soap or the equivalent [g]. It does not "wash" anything. Instead it holds dirt particles in suspension, which is why it gets darker in color faster than non-detergent oil (if you can even find such a thing these days), which lets the particles settle out.

Certainly this procedure has increased the chances. Is it an absolute certainty? Absolutely NOT !! I think you might put your mind to rest or buck up for the inevitable by asking a guru to put the good eye on your particular vehicle (pop the valve cover and inspect the camshaft etc.) If you dont have any issues, motor on!! Then for sure switch to M1 TDT 5w40. If you have issues then you can proactivately plan what to do and ....when.VWBeamer said:I jut a 2004 Tdi, the previous owner did a 5K miles OCI using Rotella synthetic oil.
Car has 77K on it now, think all the detergent has harmed the motor?
Can somebody tell me why its of any benefit to change an oil early, and don't tell me because it looks dirty either.turbocharged798 said:I am sorry, but I do not buy the fact that changing an oil in a PD every 5K is going to cause a worn out cam. Will you be wasting oil? Probably. Will it result in slightly higher engine wear? Maybe. Will it cause extreme engine damage? I say impossible.
Well no, it is just what ACTUALLY HURTS is not statistically significant enough to cause repair. This is of course what the qwikie lubes depend on. I agree it is (more than) wasteful. Again ANY lubrication used in the PD engine or any other for that matter will not take a hit in many successful lawsuits !!Dimitri16V said:5K oil changes won't hurt anything. it's just wasteful , that's all.
the PD fiasco seems to have few variables.. questionable engine design , mediocre ( 505.01 ) oils and incorrectly manufactured parts.
there are all to blame
Never said that it was a good idea to change it every 5K as there clearly is no benefit. I was just pointing out that changing at every 5K will NOT (IMO) cause engine damage.Can somebody tell me why its of any benefit to change an oil early, and don't tell me because it looks dirty either.
I brag on someone then fuss. I guess it is ok in some cases. There are times when I need to be fussed at and hopefully it does some good.Drivbiwire said:Can somebody tell me why its of any benefit to change an oil early, and don't tell me because it looks dirty either.
Give me actual data based on oxidation, wear metal content and size, soot content and %, TBN, viscosity break down...Name one reason to change an oil earlier than 10K.
I can say this with ULSD even 10K is a waste of time since the TBN reserve easily accomodates a 15-20K interval without risk of acid formation.
Below and FWIW are actual wear metals (20ppm fe) in a 10K sample showing the particle size to be less than 1 micron in size. The particles are aligned due to a magnetic field on a glass plate. This size range of wear metal is too small to cause any abnormal wear in any motor and harmlessly circulates inside the motor due to dispersents that prevent them from conglomerating.
So again show me one data point that indicates why an oil needs changing.
