Just got the wife a 2015 limited with 23k on it. I have driven it a few times and we took it on our first little road trip. I noticed it is a slightly louder engine from the start. When we got back I cranked it up the other morning and it sounded like a rod was starting to knock. Pop the hood and start listening and there is definitely noise coming from the valve train (diesel like as it has been described).
I check the oil and what the hell, it is at least a quart low
We literally bought it from Carmax a week ago and I swear the oil was fine when I did my inspection of the vehicle. The oil looked like it was conventional with some miles on it but still clean so I had just planned to change it to synth at the 3k mile mark.
Anyways, it took at least a quart, bottom mark to top maybe more as I was pouring from a 5qt. container and couldn't see the marks. It may have made it ever so slightly quieter but it for sure seemed to smooth it out and make it sound less like solid tappets.
I was honestly a little scared we bought someones junk engine or it had been damaged from oil starvation, but now that everyone says it is normal I feel better. I haven't started really studying the 1GR yet so good to know it has rollers.
I am a little pissed about it being at least a quart low. Anyone else notice when you add oil it seems to get on one side of the stick up towards the full mark? Maybe they thought it was full or they just shorted it a quart, the oil was changed by carmax about 1k miles before we bought it.. so much for their supposedly impressive inspection checklist. Trust but verify.
Apparently when you are adding oil it somehow gets on the one side of the dipstick. Unless you pay close attn it looked like it could have been full unless you look at both sides while filling it.
