early 95 with stick and only one o2 sensor. Only 1 o2 sensor wire too. I'm not sure if the car needs proprietary equipment since it's not odbc II (translated where to take the car or what Motronic test equipment I should ask the shop to prove they have before I waste my time with the unqualified.)
The test results (done 3 months ago)
We've updated the equipment, and averages for the 2.4L are based on oil run ~6,000 miles. With that change, iron (from steel) is higher than expected for a short oil run like this, but it's not something to worry about. Iron has been stable so far, so this level may more or less be the norm for your Volvo and the use it sees. Sodium could show coolant in the oil. It's just not enough to be sure at this point. The viscosity is a little low, but neither that nor the 0.8% fuel is problematic. Check back on iron and sodium - we'll know more about sodium next time.
