All was quiet for the Saab during the month of December but I noticed that as the weather got colder, I was having a harder and harder time cranking up the Saab. As I moved into late December and January, on really cold days, I was having to use a battery charger or jumpstart the Saab to get it going. Also, January was time to do my first oil change with the Saab.
In hanging out on the Saab forums, I learned that the major issue with the early Saab 9-5s is a problem with the engines seizing up due to a combination of a flawed design in the PCV breather along with Saab/GM's oil service interval for oil changes being every 10K miles along recommending dino oil. Combining all three creates a situation where the oil actually cooks in the bottom of the oil pan, then the solid/semi-solid parts start clogging up the oil drain. Eventually it clogs up enough that it starves the engine for oil, causing the engine to seize. Pretty much the automotive equivalent of a heart attack from clogged arteries.
Based on my new knowledge, I learn that by simply getting a PCV update, changing the oil every 5K, and using 0w-40 full synth, the issue of engine seizure with the early Saabs virtually disappears. By January, it's been 5K in miles since the P.O. changed the oil. I make sure to do the oil change with the recommended oil. Of course, I do the oil change myself.
A week later, the weather is cold enough that I know it's time for a battery change. Through the bizarre nature of 21st century shopping, it's actually cheaper for me to buy a battery online from Auto Zone and then go pick it up. It was going to be about $20.00 more if I simply walked in and purchased it from the store. Weird. I purchase the battery online, drive out to the store and let them install it.
