I drive a 2021 Acura TLX Type S that has 10,000 miles on it. I put premium gas in it because the manual recommends at least 91 octane but says it will run just fine on 87. Do you recommend I continue putting premium in the tank or am I wasting money?
It will produce more power and get slightly better gas mileage with premium fuel, but if your owner's manual says it's OK to use regular you can try it, or mid-grade, and see how much of a difference it makes.
am I wasting money?
That's up to you. Try it and see if you notice any difference and decide if it's worth it. Chances are it's not.
What’s the exact wording in the manual?
I have a 2014 Lexus GS 350 all-wheel drive . the manual you're only supposed to use premium gas but I always use regular and it didn't make any major difference in performance or gas mileage
