What have you done to your Silverado ZR2 this week? 🛠️

[AXE]

Today I changed the oil and filter on Big Blue. The truck is currently at 10,000 miles and this is its second oil change. The previous oil change was at 5,000 miles.
Each time I have changed it, the oil is very dark and has a gassey smell to it. But there is no metal in the oil.
Each oil change I put Mobil 1 0w-20 high mileage oil in it and a K&N HP-2012 oil filter.
If there is anything you guys would do differently please let me know.

Yeah, I wouldn't us High Mileage motor oil for a vehicle with less than 75k miles or at all. You should be using 0W20 Dexos approved oil.

Also if your concerned about contamination and wear you should be sending in an oil sample to a lab for analysis. You can see my thread on the oil sample for more information.

If you have contamination, it's time for warranty work at your dealer.

I've used K&N filters in my bikes and have cut them open. They are fine too use. That but on the end is the best.
