My 25k mile Blackstone Report

I drained the factory fill at around 4k miles then did the free oil change at 10k. Did it myself at 15, 20 and 25k. This is the 25k report. Only reason I use Havoline is it comes in the recommended weight and the convenient 6 quart container. My commute is only 3 miles and carpool for the kids also adds some cold starts and short trips. Not concerned about if the oil will hold up but curious how long it could.

Based on my usage it's nice to see despite the short trips the oil could be good for 7k miles. The OCD in me wants to stick with 5k because it's easy to remember but the lazy person wouldn't mind extending it to 7k. Either way it's nice to have the data and peace of mind.

Previous truck, 2011 Titan I was able to use 7k OCI based on Blackstone's data under similar use.

 

Curious on the turnaround time to get yours back?

Recenty sent one in on mine and awaiting the results.

 

Almost a month. I forgot to log the tracking number when I dropped off my sample at USPS and I also used a very old pre paid envelope so I wasn't positive if it would even make it there.
