What gas I should USE??? Lexus 1992, ES300?

Hey, I heard that some vehicles have better MPG when they actually use higher grade of fuel, well I’m not sure what gas I should use. My car manual does not state anything about it, and I also was wondering if 1992 engine in my Lexus can benefit from higher grade fuel, or its just wasting of money and I should stick with regular gas???

Thanks.

Answer:
I have used regular unleaded in all my Lexus models and have had no noticeable decrease in performance. Since your model does not specify a grade using regular will save you money. The higher grades of gasoline will not provide superior noticeable performance.

Answer:
87 octane is suggested by Lexus. You should use what the manufacturer advocates. If your automobile requires 87 octane but you use 85, it will retard the timing of the engine, resulting in diminished performance and economy. It isn’t necessary, however, to use higher octane gas than what’s recommended. Even though it won't harm the engine, any minimal increase in fuel economy will be offset by the higher price of fuel.

Answer:
regular should be fine in most case. If not, then you’ll need to move up a grade. How can you tell? Listen to your engine. if it begin to knock, then you would need to move up (or find different gas station)
