I have a 2017 Isuzu d-max, 3.0L diesel engine, with oem intervals saying that i change coolant (using genuine Isuzu coolant) every 2 years regardless of distance.
One of the recommended fluids in the manual, Havoline XLC, specifies that it could be used for 5 years of 150k miles/250k kilometers.
I'm torn whether I should adhere to the 2 years interval or I stick to what Havoline claims. Any advice appreciated, thanks.
