Just looking for some help on choosing an oil. Here are the stats. 1.5 Liter Toyota engine (same as Echo) 108 hp. 5 speed manual 4 qt sump There is a little blue light that is on when the engine is cold, and I told wife not to take engine over 3000 rpm when on. It turns off in about 3 to 5 miles with temps in the upper 80's. Located in Peoria, IL (Highs in summer up to high 90's low in winter down to teens or slightly below) Going to change to a Dino at 500 miles to flush out gunk. Then change again at 1500 miles to a synthetic. Should have the 500 miles by this weekend, and the 1500 miles well before winter. Wife drives car to work and back twice a day mostly highway (18 miles one way). Scion (Toyota) suggests 5W-30 I am thinking of going with Havoline 10W-30 for the first change at 500mi up to 1500mi. Then using GC 0W-30 for 5000 to 7000 mile intervals thereafter. I know this doesn't go in this forum, but planning on using Purolator Pure one, or Bosch filters...any suggestions on these as well? Thanks for the help!
