I change my oil about twice a year. I drive about 12,000 miles a year, you do the math. I use Castroil 5w30 from Walmart. Haven't been able to bring myself to use the Supertech oil yet, but I may in the future.

I went from mobil 1 to oreillys synthetic, the orielly brand has to be the cleanest oil out of the bottle that I have ever seen.

I'm oldschool, oil & filter change every 3K, oil still looks very clean when its changed. Last week the valve covers from my 219K Burb were taken off to powder coat and the inside of the cylinder head is as clean as a new crate engine.

Here you are, everything you wanted to know about the OLM:

ZDP depletion and GM oil life monitor - Bob Is The Oil Guy

I run Mobil 1 and a good filter regularly to 10k and it's around 40-50%. I do have faith in it's accuracy.
