First oil sample
I have had the truck just over a year. 107k on it. I change the oil just every 5k. Took a sample and sent it to Blackstone. 15-40 MotorCraft oil.
Everything came back good except high potassium 43 averages are 9. they sited antifreeze but probably not because all other were well within range. They said it's probably EGR compounds. But only see this in new engines some times in older engine. Not to worry. So what do you think?????
I tried to post the report but could not find a way to link it.
Thanks
