| Guys, my apologies for beating the dead horse, but to dumb it down so I'm clear. "Premium required for optimum engine performance and fuel economy" = 93 (or 91) is best for car/engine/ECU design on this vehicle, but 87 will not cause engine damage (if I'm hearing Scotty right in the video) just might lose some HP and MPG efficiency. Thanks again to all for the help. | |||||

| Scotty has stated (many) times "the car's computer can compensate". The lone caveat being the car not having a high performance or high compression engine. Or as is in this case, premium is not required, got it. | |||||

| Thank you for the reply. As I said I'm totally willing to use premium, and I agree that reality is the cost of ownership for a luxury car will be higher, I'm comfortable with that. I'm curious as to the validity from a mechanical standpoint. Frankly, I was surprised to see so much varying opinion on both sides of the question. | |||||

| Don't just focus on individual words. What is the entire paragraph? It usually says something like "premium fuel required to achieve maximum performance. In other words, you lose a couple of horsepower with regular gasoline. Your Lexus will be fine. All modern N.American cars with naturally aspirated engines have ignition retard lookup tables in the computer for various octane levels that it can switch to. If your engine has forced induction then you can pay attention to fuel. Scotty says the same over and over and he's been a mechanic a long time. | |||||

| owner's manual The knock might have been occasional when the car was new (you didn't provided mileage), but after 11 years it's probably not in top shape anymore. An "italian tune-up" might help get rid of some carbon deposits, or a professional cleaning if you really feel like it (but that might end up costing more than using the premium fuel). | |||||
