VW longlife oil confusion??????
Discussion
Hiya guys,
Basically the missus got the golf TDi serviced from an independent garage and the engine went noticably louder. The mechanic claimed that the engine has high mileage (114k) so needs thicker oil so replaced it. This made it quieter but still louder than before the change. Now this has really been getting on my tits! So I had a look at the service booklet and the car has previously been serviced by the dealers using longlife engine oil. Now after a bit of research I am a little confused as some people are saying you have to continue to use the longlife and some saying you dont? Any help here would be appreciated. As I dont want to pay £50 for the oil if it doesnt solve the noise issue. As I have read on other websites that the TDi PD engines can be slightly louder than other diesels. Am i just being anal? Just dont want the engine getting wrecked!!

Its a 2005 1.9 TDi PD!
You need to exactly what is recomended they can have serious issues otherwise!!! If you go to a good motor factors, or a oil co like millars they will sell you a bulk 20liter pack of the right oil for it....

If its on a variable service interval I would put VW Longlife III oil in it. This is what we use for most VAG in the workshop as it will cover most. The only time I would not use it is if the car is old (pre 2000) or the oil is listed as not suitable for the car. To be honest it's going to be difficult to say if fitting the correct oil is going to make the engine quieter but at your mileage I would want the correct grade of oil for the car.
I have been servicing mine myself from 92,000 miles. I am on fixed intervals and have always used the Platinum oil from the dealers, think its quantum 5-40 but will check. If it were on variable serviceing it would need the longlife which I think is thinner.
I'll have a look in the garage and let you know.
Its now on 218,000 miles with no trouble, increase in noise, or turbo issues. Not had any engine work outside the DMF and Timing Belt.
Checked
The Fixed service 10,000 mile oil is Quantum 5-40, the variable is Quantum 5-30.
There is alot of opinion about on what is best for the car, some say the variable is fine, some hate the concept of 25k between oil services. The one I went with is once the car gets to the 6 figure milages its better on the fixed servicing, each to there own though. I would warn though, be selective what you put in it, the PD engine has a reputation for being fussy and ASDA Smartprice would not be a wise choice.

Just to reiterate - whatever you do, it MUST have the correct PD oil in it (VW type 501 or better) or it will wreck the cam lobes and pump tips in short order.
I know that this is an old thread but DO NOT use VW 501 oil in a PD engine unless you want to damage the engine. You need either 505.01 (5w40 - fixed service interval) or 507 (5w30 - variable service interval).Defcon5 said:
How exactly does it damage it?
The PD engines have very high point contact forces on the cam lobes and followers. The oil film is under a lot of stress here, and will break down if the incorrect oil grade is used. If that happens, you have metal to metal contact, and the lobes and followers will quickly be ground away to nothing.More information and some pictures here.

However I would NOT run ANY engine on a longlife scheme,@, been there done that etc, it's just not worth it I would even go so far as to say 10,000 miles is really pushing the oils in these engines for the reasons stated and illustrated by Defcom5 above.

However, I have recently treated my high mileage petrol engined 4 cylinder turbo, in line with their recommendations, with the above product and the reduction in noise was quite noticeable, I look to noise being one major indicator of friction and possible wear.
I am NOT connected with the product/company at all apart from being a very surprised and happy customer.
@ lease vehicles obviously are a different case...
O/T-Incidentally I have used a similar product, miltec, from the US, on my semi-automatic weapons. Once again the difference once treated was immediate and dramatic and could be felt by manually operating the weapons mechanisms however, in this case, a hair drier was needed to heat the components lol.
