Oil Analysis - Oil Technical
We're not particularly concerned with the well being of our tractor's tired L-head Four (or it wouldn't get the used oil from our other vehicles) since it's not an expensive or hard-to-fix motor. Oil analysis makes sense when there's more money at stake, which includes most any diesel engine. Even our lowly Blazer's 6.2 Detroit gets a sample taken at each oil change. At about $10 a year, that is a very inexpensive early warning system. View Related Article
