Best or not i don't know but... I use & have used for years
I'm not keen on the new box it comes in now though

As above, 507.00

That's the long life spec isn't it?
As long as you're using one of the two PD spec oils 505/507 (I think), you'll be fine regardless of brand. What's actually far more important is how regularly you change the oil, I've always changed at 5k miles.

5W40 505.01 is the correct PD spec as is the later 5W30 507.00 LongLife spec .

Now if an oil is a PD spec and a LongLife spec it must be of a..... quality.

That's the point, 507 is 'better' in the sense it's long life oil, but tbh the whole long life oil is questionable. You wouldn't keep washing dishes in used dirty water no matter how good the dish soap would you? The 507 long life oil is meant for 10-20k mile changes which is far to long. Focus on changing regularly, it's more important than picking 507 over 505

That's fair, I've always changed at 5k intervals so 505 is ideal, that being said the price difference can often be small now days.

Now you can use 507.00 for 5k intervals .

But you'll have a job to beat my 1.9 AVF 507.00 servicing .

Not quite , use the higher quality 507.00 , higher anti wear , higher this and that for an annual 10K / 1 year , that's the chicken dinner .
I’ve heard that 5w30 is too thin for the 1.9 pd engines… because od the camshafts… i change my oil every 8-10k kilometers so thats about 6000 miles

There's nothing on car forums like oil folk law that just falsely gets repeated by the next .

Grade is too crude a measurement and comprises of roughly 4 centiStoke units so over the two grades there are 8 units , all measured at 100°C , in Castrol's production the two VW specifications were separated by just one centiStoke so the 5W30 507.00 was a thick 30 and 5W40 505.01 a thin 40 .

If the goal posts were moved by just half a centiStoke the two oils would come under one grade .

Also viscosity doesn't dictate oil film strength , it's the ingredients namely the oil basestock groups and additive package concentration .

I always used to Quantum platinum in my mk4 golf pd 130 & then went with the longlife 3 in the b6, only as thats what was previously used.
As Gazwould I'd just make sure it's changed regularly with the correct spec, even though i used longlife oil i do change it annually which probably equated to 8-10k miles in the past but now is more like 3k! but for the difference in price between the platinum (505.01) and the longlife (507 00) may as well go with the higher spec in my mind

So in the end would you reccomend me 5w30 or 40? Price doesn’t matter to me i just want the best for my car.
