Thank you for that. I printed it off to have on hand when I take it in next. The truck is a 1989 Ford F-150 I purchased from the original owner. I do not remember the techs name as it was almost a year ago I got my oil changed. I normally do most of the maintenance on my vehicles, but when they were willing to do the work and provide supplies for almost half of what I can purchase the supplies for, I jumped on it.
