Or... you may have seen it from a 1st Gen reference.
Prior to Toyota installing the "Maintenance Required" idiot light, the change intervals for many (all?) vehicles was 5000 for severe service and 7500 for normal service.
That was the case for my '03 Tundra and my wife's '00 Echo.
The Echo got a facelift and a new dash in '03, and the 7500 mile option was dropped.
I suspect if a 1st-Gen Tacoma owner actually reads their owner's manual, it will allow for up to 7500 on the '95 to at least '00 models. If the "Maintenance Required" light was added for the '01 facelift, then the 7500 mile interval would have been removed.
The GM, BMW, Mercedes, and other "oil life monitors" actually have a bit of intelligence behind them. Some actually take a reading of the capacitance of the oil. The GM monitor in my '06 Silverado took into account driving conditions, RPM, temperature, etc... it would trigger anywhere from 8000 to 12000.
The Toyota system is just a timer. 4500 miles it flashes, 5000 miles it's on. Unfortunately, even though WE may be able to make an intelligent decision on whether or not we can go longer, our factory warranty and extended warranties do not give us that option.
