Can I put 87 in my Lexus IS 250?
Lexus IS250 Owners’ Manual wrote: Premium unleaded gasoline with an octane rating of 91 (Research Octane Number 96) or higher required for optimum engine performance. If 91 octane cannot be obtained, you may use unleaded gasoline with an octane rating as low as 87 (Research Octane Number 91).
First, using too low of a grade of gas can lead to engine knocking, which can cause long-term damage to your engine. And second, using regular gas when you should use premium could void your warranty, meaning you would have to pay for any costly repairs out of your own pocket.
