This was the 3rd oil change on this truck. 5k, 15k and 24k miles. I sent the 15k mile oil change off to be tested and it came back pretty rough. Blackstone recommended a 7k OCI but I just couldn't find the time to do plus I was really hoping that the 15k was a good washout and the metals had reduced, which is what happened.
The 5k oil change was a 'free' oil change at the dealership, which they supposedly put in bulk 0w20 oil. The second and third oil changes were by me using Mobil 1 0W20 extended performance and Toyota cartridge filters (what a PITA!)
I will probably run this oil 11k as recommended and to get it to an even 35k for easier remembering of OCI. I'm very pleased, this is on par with my Hondas.
