Strange, I think it has B200K engine. I thought that it came only from '86, which should be more economical, am I right?
One more question, does this engine accepts fully synthetical oil, whic I want to use for fuel economy?

Fully synthetic 15w40 is recommended by Volvo for all 300's now - Read this in an update from Volvo themselves.

I am going to use ELF EVOLUTION SXR 5W30, where I can find Volvo recommendations?

How do I find which gasoline is most sutable for my car. I read that in '85 there was versions for leaded petrol. I think it would be OK to use 98E.

I recently have read that actually this modification not as godd as I thought, If I knew it earlyer maybe I would not buy it:

„This low friction design was used in 85-88 and was a "failure" from Volvo. Thousands of engines broke down prematurely and Volvo had to cover plenty of warranty on prematurely broken engines.“
