Hi,

Ive just been made aware that my 2003 octavia 1.9tdi 110bhp ASV engine is not a PD engine! I bought the car with 100,000 miles and is now 170,000 miles. For every 10,000 miles I have been changing the oil and using Millers VW spec semi-synthetic xfe-pd 5/40 as it conformed to 505.01. As my engine is not pd, my question is have I comprimised my engine and what oil/grade/code should I use?

Many thanks, Andy

I don't think so...oils for PD engines are stronger.Contrarily,a PD engine with a non-PD oil would be a problem.

I'm no expert but if you've done 70k miles on the wrong oil and not had any problems i would say its fine! Although i would start usign the correct oil. Arent you meant to change the oil every 6k miles anyway on these diesels?

Every 10k on all Skodas using fixed servicing.

PD oil will be just fine, and if I were you I'd continue using it as you have used it for that amount of time.

Thanks for the replies. Ive never had an issue with the engine so far, its always started and ive never had to top it up between changes. It may be a case of better the devil you know so might keep using it. The only thing ive noticed recently was that my coolant temp takes a while to get to 90c. Outside temp ave 0-5c. Had cambelt/pump/thermostat changed but still the same. When at around 70c and I blow hot air in cabin, the temp needle starts going down. This never happened before, it would always gradually rise to 90c. Saying that, once its at 90 it doesnt budge

When at around 70c and I blow hot air in cabin, the temp needle starts going down.

That's because you're re-routing hot coolant through the heater matrix which will lower the overall temperature of the coolant. It's probably just taking longer to get to 90 because of how cold it is outside at the moment. As long as it gets to 90 eventually and stays there there's nothing wrong with it.

My engine takes 5 minutes on the motorway at the moment to get up to 90oC and thats with a partially blocked up front grill.

what did you use to block it?

Diesel and cold! My work van takes about an hour to heat up lol

You've used a higher quality oil ( and slight more expensive) than you really needed to - no problem . I would continue to use it.
