Damn, that seemed quite quick.
Do you happen to know what to do to it/keep an eye on the keep the engine in running condition? My mechanic said it may not be a good idea going too mental with fuel/injector etc cleaning products as the car may not like being that clean again (if it hadn't had it done for a while).
Bought some new spark plugs, oil, filter and a couple other things from Toyota the other day, even though most of that may have already been done recently.
