But if you ride like that, you should change oil more often? or is the oil change every 4K interval ok?
Keep in mind I'm talking from the vantage point of larger displacement engines, I'm a V8 5.7 liter guy.
Occasional runs around redline are not going to effect your oil quality. But if you find yourself around red line all the time, down shifting hard and using engine breaking often you will want to use better grade oils and increase the frequency to 2500/3000 miles. This isn't really do to oil break down as much as blow by. At higher RPMs and during engine breaking you see a lot more blow by of exhaust gasses in and oil out on the V8 engines. At the very least make it a habit of checking your oil levels every time you fill your tank. My GTO will use @ 1/4 quart (out of 6) of oil if I drive her 'normally' for me. If I have a chance to get to a track and/or get up north to a couple of my favorite twisties I have used as much as 1/2 to 1 quart between changes.
This is real world exp from a V8 but I wouldn't be surprised to see the same on a smaller i4. I don't' beat the FZ that hard and put less than 1000 miles a month on her. I don't have enough history to say how she reacts.
