Hi to All

I have been having the Fabia vRS serviced at the prescribed intervals and the oil used is Quantum PD. The oils seems to keep everything running quietly for the frst 3500 miles then the engine gets progressively noisier until next service when it quietens down with the new oil. I guess that the car spend a disproportionate amount of its life at low speed low gear use which may make for early oil breakdown. I really dont want to start changing oil every 3500 miles. What do you use in your Fabia vRS and does it work over the 10,000 miles service interval or do you notice the car gets quieter underbonnet after a service?

Also, anyone know what the toughest PD 5W40 oil ot there is? By that I mean the one best suited to prolonged drain intervals.

You could try Castrol EDGE 5w-40 Turbo Diesel engine oil.

It's Fully Synthetic and will stay in grade with no drop in 'performance' over 10k miles.

I use in my car at the moment, having flushed the factory fill out of the car at 2800 - together with little iron pieces not trapped by the filter, which incidentally looked like it had been kicked around the factory before it was put in the engine.

Factory fill is Fuchs Titan Supersyn Plus 5w-40 for the PD engine. Talk to Guy at www.opieoils.co.uk for your requirements and free postage on orders over

i change the oil every 2.5k , and the oil+filter every 5k , but i get the oil for free at work and the filter costs me a fiver , the last lot of oil was only in for about 2k miles due to having been thrashed to the Ring and back

Hi Zebra

I have spoken to Simon and Guy about this and they reommend changing every 5K or so even with the best oils. I am trying to glean some opinions on other fully synthetic oils out there that they dont sell. The Edge stuff I ran as topup in the cars first 10' date='000 miles and it seemed pretty good. I will get onto Castrol on Tuesday to find out a bit more about it, namely what family of synthetics it comprises of.

Of what they do sell, the Fuchs Titan and Motul VW Specific look good. Thinking back to the first service, there was (if I remember correctly) very little change in engine sound before and after service, so if it was filled with Titan Supersyn PD, then it may be the best choice.

Anyone else tried any of the others, Q8, Fuchs, Motul or Castrol Edge?

Surely there should be no difference in quality of oils made to VAG specification 505.01 for TDI PD engines regardless of the manufacturer.

I use Millers PD oil in my Polo 1.4TDI PD now and notice no difference to when the car was in warranty and being serviced and refilled with oil supplied by the main dealers.

I forgot one important difference the price of Millers oil is about half the price of the VW main dealers

I too use Millers PD oil in my Furby VRs and change it, along with the filter, at 5k intervals, the oil cost me £30 and the filter £7 from the dealers. I havn't noticed any difference in sound before or after the oil change.

There is a difference in quality. There is a difference between meeting the spec and exceeding the spec. If your car is standard then any 505.01 spec oil should meet your requirements for the full service interval. If your car is modified or subjected to demanding conditions then a full synthetic would be preferable. This will degrade more slowly, stay in grade longer and be better able to protect the engine effectively.

Hi

There are really very big differences in oil durability. An oil is specified to meet a minimum requirement which it may do comfortably or just scrape through. Next there is the aspect of how well the oil stays within spec. Cheaper basic oils are prone to heat breakdown and shear breakdown, so over the course of the oils service, it becomes less and less effective. There is also fuel dilution and water dilution resistnace and corrosion inhibiting actions, as well as particulate dispersal and detergency to consider.

The best oils do all of this far far better than the worst. For my driving school car, the amount of time the engine is running against the miles it covers are quite high, so the oil gets a tough time. With the original factory fill, there was little change in engine sound over the service interval and no perceptible quietening after service, showing the oil had maintained a fair degree of its effectiveness. On the Quantum PD stuff, there was noticable increase in engine noise at 3500 miles on two fills and a service or oil change quietens the engine substantially, so I assume this oil is less effective than the factory fill.

What I would really like is a PD version of the Motul 300V I am running in the MR2 at the moment. A fully ester composed synthetic, the engine runs silken smooth at any temperature, has no rattle or loosness when hot and is immediately visibly very much cleaner inside than on the Magnatec that it was originally serviced with.
