That's excessive, but won't hurt anything other than your pocketbook.

and the environment... and US dependence on foreign oil.... which are two big reasons why the yaris was a smart/cool car in the first place.

The yaris isn't a truck/suv... its not a heavy duty vehicle that has to work hard. buildup should not be a problem unless the driver uses only the worst gas possible, never revs the engine past 3k, and goes longer than 5k with dino oil before changes. Even then... it'd probably take longer than 50k miles for significant buildup to occur. Treatment before 75,000 miles is ridiculous I think.

Im not going to lie. I'm known for being fairly hard on my cars. I like to have fun. But I also take care in that aspect and keep up with my maint. Toyota suggests 5k. In 5k my car could see 2-3 autoX and various types of cruises. Plus, ive been told that my wheels are tough on the motor. I've already seen them sabotage my MPGs. I tested it with a 2 week span of no more than 45mph and slow revs and shifts. I netted at best 32mpg instead of the 41 stock.

Thats not the argument though. I have always changed my oil at 3k. Even with synthetics. But they were all turbo cars and high hp ones. My legacy also gets 3k oil changes every 3-4 months with regular old 5-30. I just dont see how a 3k service is a bad thing.
