I get bad gas mileage in eco mode. The car is slow and u use more gas trying to get up to speed. I get about 47 mpg in normal or sport mode. 43 in eco. Sport mode feels like RWD and still uses the electric motor.
Direct injection is always an issue. Intake valves get gunked up and chokes the engine. The IS250 has direct injection the IS350 has direct and port injection. Oil catch cans are very useful even for non turbo cars
I was looking around a lexus parts site and the engine costs about $2000 so they are almost paying for a new engine, and the rest is labor.
Thanks for sharing now I know why my brakes are loud
No it's my first hybrid. I peeked under the hood and saw inverter coolant, engine coolant, and brake fluid. Don't want expensive repairs. Figure I just drain and fill with toyota fluids plus brake bleed and spark plugs
