New Saab owner, question about spark plugs, oil.

[linas]

So we bought it a 2006 9-5 linear 2.0 T automatic.





Power was boosted to 154kw in 2009. So the question is what spark plugs this car need? NGK BCPR6ES-11 or NGK PFR6H-10?
Another is about oil. We are planning to use 5w30 with GM-LL-A-025 spec. Following that spec do I need to find correct ACEA spec or any from A1 to B5 will be fine?

That looks rather nice

Might sound obvious but for my 9-5 Aero I follow the spec in the owner's handbook. It should tell you exactly which plugs and oil spec to use for the 2.0T and I see no need to deviate from that.

Thank you

The problem is, that I dont know how engine power was boosted. From what I red, my understanding is that if 2.0T engine was boosted (tuning kit
M01-) you need to put different spark plugs. So this is dilemma.

So I found out that my Saab was tunned by Hirsch performance. I send them my car's VIN code and they advised to use NGK BCPR6ES-11 spark plugs.

OK, the standard plugs.

And what about the oil? Why would you change from 0W-30 to 5W-30? (Genuine question! )

1. I looked at service history and 5w30 was used more often.
2. It is easier to find 5w30 with GM-LL-A-025 spec and ACEA A3/B4. I'm gonna try Synpower VALVOLINE 5W/30

Well it looks great. Enjoy it!

5W-30 should be fine, as long as it meets or exceeds the GM or A3/B3 specification.

Great looking 9-5, good combination with that color and 5-spoke Aero wheels.
