This is in my Jaguar S-Type 3.0 V6 with 96K on the ODO. The car sat in a garage for almost 2 years. I began driving it again but put very few miles on it. Only 2500 miles since the last oil change (Oct 2010). This car has 6qt oil fill and does not consume any oil. The oil is a synth blend. Upon inspection the oil appears clean, like maple syrup. Engine runs smoothly. I'm wondering whether there is any reason to change the oil now. Typically I don't change oil until it has at least 4-5K miles on it. On my other car I've been doing 8K intervals with full synthetic. So change the oil now or wait another 3 years to get to 5K?
