My comment is based on the convertibles being intermixed in production with the coupes. there wasn't a pile of roller L98s that got plugged into only rag tops. Rollers were more of a hard break in production than a running change.

I tried to find zink rich oil in CZ but I was unsuccessful. So I ordered ZDDPlus additive from US:
http://www.ebay.com/itm/3-ZDDPlus-ZD...-HfB1g&vxp=mtr

I will use it probably with Mobil 1 EPS Formula 5w-30 (the only 5w-30 Mobil 1 oil available in CZ)

Or do you recommend other like Castrol EDGE?

In Mobil 1 guide there alteady has 900 PPM zinc level

How much zinc should I add to it?

Thank you.

I'd think there's better choices for the oil. You mentioned buying here in the US and shipping yourself so if it was from the OWNER and not a broker reach out and see what he used.

What 10W-30 oils are available in CZ?

The previous owner used Mobil 1 full synthetic 5W-30.

10W-30 almost nothing, I found just Petro-Canada Supreme online, but I might be able to order VALVOLINE® FULL SYNTHETIC at local oil shop.

in general oils, that are normally available are:
Castrol, Liqui Moly, Mobil 1, Valvoline, Total

Fully synthetic oils designed for VW, Audi and Skoda PD (Pumpe Deuse) diesel engines have good anti wear additives.
That particular range of engines had issues with wear on the diesel injection pumps if the incorrect oils were used. With the corect oil, they are almost bullet proof. The spec is VW 505.01. The latest spec low SAPS oil is 507.00. These are what I use.
