Hi,

I've searched previous threads regarding preference over either 505.01 or 507 oil, and so far, I have been unable to find a definitive answer!..

I have a Fabia 1.4 PD TDI, on a variable service plan (10,000 miles/once a year).The car does not have a DPF, and therefore the manual suggests using 5w/40 oil with 505.01 specification. However, the car has recently been serviced by a Skoda dealer and filled with 5w/30 507.

Is this because 507 is now accepted as a betterment over the 505.01? I could understand this being so, however, what worries me is the differences in the oil grades - 5w/30 opposed to the reccomended 5w/40. I am aware that the cam lobes on the PD engines are suspected to high levels of wear, and thus am worried that the engines requires the thicker 5w/40.

What spec does everyone else use?

Thanks,

Hello storm blue 2. Welcome to the site and nice choice of car. I had one for 5 years with no problems ever, and so nice to drive once you get the hang of the 3 cylinder motor. Very potent and very economical.

Where the oil is concerned, don't worry. 507 is fine in your PD, but there is a preference even at most dealers for the 505.01 in a car with no dpf. Someone may have incorrectly thought you had a dpf or had a car on variable servicing. Or they may just put 507 in all their engines now as some do if it's diesel. Yours incidentally is on, or should be on fixed servicing and from your post above, it is. I can tell you that the same engine in the 1422cc PD Greenline with dpf, and the 1.9PD with dpf both run fine on the 507 grade oil so it's perfectly acceptable. I would next time go for the 505.01 if it were mine as I like the sound of a 5-40 better than a 5-30. But both give the same protection level and both have the extreme pressure agents in them to prevent cam wear. It really is only in the upper heat range in a blistering summer that it would conceivably make any very slight derogatory difference to the amount of protection a 507 would afford over a 505.01 and then only if you were driving it flat out all the time at very high revs pulling a house behind you all day and everyday. Even then it would still really be ok and no harm would come to anything. In this country 507 is ok all year round in your PD. Just enjoy your car, it's one of the best and very tough I promise you!

PS. There is a myth the PD engines wear out their cams, and yes...I've replaced a cam in a 1.9pd engine that had been run on the wrong oil. If it is serviced correctly and the right oil used (either 505.01 or 507) that just doesn't happen. It tends to happen on second hand cars where people service it themselves and use the wrong fully synthetic oil without the high pressure agents in it. Use the wrong oil and the cams become plasticine in just a few months. Most PD's can cover between 300,000 to 400,000 miles without any problems. I've seen the 1422cc PD without dpf with 289,000 miles on the clock and it was a sweet engine still.

Thanks for the reply Estate Man.. And yes it is on Fixed Servicing, my error! I too would prefer to run it with the 505.01, due to it being a thicker oil. It may also help reduce noise, not that the noise of the 3 cylinder is half as its made out to be anyway!

When using the search functions on sites such as Halfords & Eurocar Parts ect, they all suggest 5w/30. I know you should stick to the manufacturers reccomendation in the handbook, however I thought that prehaps now 507 is also considered acceptable for cars on the fixed service & without dpf.

I may call the dealer for peace of mind. Prehaps I'm just being paranoid after owning a Peugeot for 2 years. Reliability was non existent!

We use 50501 for fixed servicing because its not long life and doesn't or shouldn't last two year or twenty thousand without going bad. 507 we use for variable servicing and or dpf. Basically because the oil is made specifically for longer servicing. However long life servicing suits motorway miles better than pottering around the town. 5/40 PD would be fine if your servicing very year.
