Lexus: Fuel type for GS 300?

I read in one article that the '94 GS 300 requires Premium fuel but all the
review I've read don't mention anything like that (they only say unleaded).
Is it only premium or can I use regular unleaded?

If your car has a knock sensor it will retard the timing if it detects
pinging. You won't have any damage but performance and mileage will suffer.

If your model does not have a knock sensor you WILL do damage over time as a
result of the pinging.

Thanks for the reply.
Even if the manufacturer recommends premium, will regular gas affect the
performance of the car, or can it be more serious?

It has a knock sensor so you will degrade performance.

How can I know if it has a knock sensor? I know nothing about cars, so would
it be part (if it IS a part) that's easily visible or would I need to know
something about cars to find out?

All modern cars have knock sensors that will adapt your engine to whatever
octane rated gas you use, at least for the octane range sold in USA. The
sensor will retard your timing slightly and, as a consequence, slightly
reduce your horsepower. I doubt you'll be able to notice the performance
difference.

It also might reduce our gas mileage slightly. But given the 20-cent per
gallon price premium for premium gas in my area, the trade-off is probably
worth it.

I've run regular in a 91-octane recommended Toyota for years with no
noticeable loss in performance or mileage. Occasionally, I've alternated
gas and couldn't tell the difference.
