Just went out to the garage and checked the oil(car has been parked since last night) and the dip stick was bone dry! Tried it 3 times and only got a bit of oil on the very tip of it. OLM says I'm at 38%. When I bought the car in August it had 40K and now has 45K. Per the dealer's little window sticker, they did an oil change in July(likely when they got the car in their inventory). So this is a bit concerning. My LS which has 129K on it and has 5K change intervals has never used any oil. There were a few times I was even over the 5K mark and it was still full. Same with my Infiniti, although it had shorter intervals(3075 miles).
So now I'm wondering, do I go ahead and change the oil or top it off and wait until the OLM says change it? If I'm going to have to use synthetic(which the car recommends) and pay the higher price, I'd like to enjoy the benefits of longer oil change intervals. Looking at the service history on my vehicle, both the recall for premature timing chain wear has been done as well as the actual timing chain was replaced.
