'09 YARIS . It reads about 3/16 of an inch over the FULL mark . Could this harm the YARIS engine ? Would this be about 1/4 of a quart over ? Should I dump it soon after the 1,000 mile break in period stated in owners manual ? Or sooner ? There's 426 miles for now , more to come . Have noticed that all the TOYOTAs we've bought are always overfull from the factory . Calls for 3 and 1/2 quarts with filter . Have been driving it everyday for an average of 90 miles at different speeds for break in , as printed in manual . THANKS
