2009 Lexus ES 350
If regular (87 octane) gas is used in a car that recommends premium gas, can the engine be damaged. I've read that the horespower can be slightly diminished and I've also read that the gas miliage can be affected as well, but I haven't read anything about damage to the engine. Thanks.
