Vehicle is a 2004 Volvo VNL semi truck with the D12 engine. Holds 7 gallons of oil.
I noticed my oil level going up as the miles racked on and thought maybe it could be coolant getting in but the test results seem to suggest a leaking fuel injector. What do you guys think?
Engine has 1,370,000 miles and was overhauled slightly by the previous owner @ around 1 million miles. Not sure what was done but looks like I may need some injector caps replaced...
