Odd thing happened on the way home last night. Oil Service notification came on but the oil trip was only registering 2500 miles. Service book lists two services, first one at 590 and a second one at 1528 miles. I bought it at roughly 2400 miles and its got just over 4000 miles now. Manual says oil service warnings are spaced at 600, 2400 and 3000 thereafter. So it appears mine has gone off either 500 miles early or 100 miles late? Confused.
