Isuzu 42 Diesel Engine β Service Time (Basic)
We log all our engine hours in a book with a running total, I know I have a gauge for this, but in a book I can note down anything else that happens and it reminds me when I need to do a service. At or about 250 hours we change all the filters, I would rather be early that late with this as it is an old engine and while currently working fine, I want to keep it that way.
