Hey I just wanted to pick anyone's brain regarding oil consumption on the 1nz-fe engine (echo, xa,xb,etc). I just want to hear people's opinions and thoughts regarding this, and how applicable it would be to our Echo. I do understand, barring any leaks, etc, oil consumption is normal, but every car and car make is different, etc., etc.
I have a 2001 Toyota Echo (Auto
) with 218,000 miles. Car isn't as quick as it used to be when she was at 160,000 miles, but she keeps up with traffic, passes cars on hills, and averages about 34-36MPG going 65-75MPH. I used to do the oil changes every 4000 (over 3,000 but under 5,000) miles with 5w-30 conventional oil. Car runs smooth and is reliable (I do have a fuel delivery issue on cold start/under 1/2 tank), which I'm aware of/living with, and will fix on of these days/years--pretty sure it's the fuel pump/pressure regulator, but that's another day).
Anyhow, when I change the oil, I always put enough oil right to the full of the hash mark on the cheap plastic yellow toyota dipstick. I always put oil in the oil filter prior to installing it At 3,000 miles, the dipstick now shows it around halfway between middle and bottom of hashmark--so its under halfway, but more than way at the bottom start of the hash,if that makes any sense. I had about 3/4 of a quart in the trunk so I dumped it in, and it shows little more than 1/2 way. So roughly 1qt (maybe 1.2qt) per 3,000 miles of consumption.
I do tend to drive it a little hard, it's basically a beater car now, but I was hoping to see if the car will last until 300k, which would be awesome.
So what I'm wondering is if I shouldn't worry about the oil consumption, and just keep tabs on the oil level? The actual cause could be anything from leaks (which I'm pretty sure I don't have), to worn rings, valve guides and seals. And, while I would be confident in tacking such an endevour, realistically I don't want to and just let the beater car, beat. So, should I worry? Appreciate any thoughts and opinions. Thank you.
