Benford's Law
Hi. I'm a new member to this board and I wanted to share a few details about the Corolla my dad gave
me. It's a '99 VE with 207,000 miles (1ZZFE engine, I think). Yes, I searched the boards about the oil burning problem and this old dark green beauty uses up about 1 qt. of Valvoline 5W/30 every 600-700 miles of 60mph avg highway driving (slow and careful driver).
I understand the rings and seals problem that is common with this kind of car but it still gets great gas mileage (38-40 mpg at 60 mph) and it still runs like a great peppy new car in spite of its expensive oil-drinking habit.
The oil has been changed every 3,000 miles since new and it won't even use any oil AT ALL until about 1,000-1,500 miles into the oil change cycle. The consumption slowly gets worse and worse until the 3,000-mile mark where I pretty much have to store a Saudi Arabian oil field's worth of supplies in my trunk to make it last through the homestretch.
I still love this old car and I would like to drive it as long as possible just to see how many miles I can rack up on the odometer.
Should I worry about the oxygen sensor/emissions? I'm not a mechanic so I don't know what to do here. I never see smoke coming out of the car.
Would switching to Valvoline 5W/30 Max Life harm the engine that has been used to regular Valvoline for so long? Is it really worth the price difference?
And, as a final speculative question....How many miles of life are possibly left on this one? It still runs great as long as I keep nursing it (I judiciously try to keep the oil level above halfway between the MIN/MAX marks at all times).
You guys have been really great at answering other Corolla owners' concerns so I thought I'd throw in my two cents. Thanks for any readings and postings.
