I have a '93 Tercel with about 125K miles. It had 89K when I bought it back in '02. The engine used a little oil when I bought it (I had to add about 1/2 qt every 750-1000 miles or so), but I believe the consumption has gotten worse. Now it'll go through 1/2 qt about every tank full of gas. It doesn't leak so I know it's burning the oil. The weird thing is that the engine still runs very well, has plenty of power, and still pulls over 40 MPG on the highway. In other words, the engine doesn't act like it's burning oil as badly as it is. Usually when an engine shows signs of wear to where it's burning oil this badly, you usually notice a definite drop in power and/or fuel economy. That's just not my case. I've always used good oil (Havoline) and filters (PureOnes), with frequent change intervals (about every 4K-5K). I guess my questions are these: How much longer before this sucker starts looking like a misqusito fogger going down the highway, and is there anything I can do differently to slow down this wearing out process? Also, I was hoping to get 200K out of this car. Is that no longer a feesable goal?
