Took my SS 1LE to the track for a lapping day, again. Spun out once but didn't have much drama otherwise as I get to know the car better. I also found that I had a much better time in Sport 2 than Sport 1 in PTM mode(VMango will probably have an idea what I am talking about). The less intrusive nannies turned out to be helpful.
My friend helped me sketch out some lines on the track map and I just had to forget it. I love contact lenses, but they can be a pain to put in, especially when I am in a hurry.
I will also need lessons to drive my car better, just has to do some research to see if lead-follow format + radio is as effective as in-car instruction...
Changed the oil on the duramax diesel on Monday. I don’t use it much, only around 2200 km all last year and I changed the oil last May. After driving daily all week I rechecked the oil today, not bad for a diesel!

I have no idea about what type of oils go into diesels. Are there a bunch of different grades and weights? Is there traditional and synthetic? How long of intervals usually between changes?
I think a lot of modern diesels are pretty picky about oil. Has to be an oil that is formulated for diesels. But there are plenty to choose from
In case of newer GM diesel, they spec their engines to use Dexos 2(not to be confused with Dexos 1 Gen 2), which can be tricky to find depending on the viscosity. Dexos 2 also is specced for 2019+ Corvettes and V8 Camaros.
