What is the concern? According to many on here, toyota designs their engines for 40wt oil usually, and it is reccomended in most other parts of the world.
Whether there is residue of some sort from oil burning, a leak that causes dropout of oil, etc. using a HDEO 15w40 will ensure top-notch cleanliness, its cheap and easy to buy in gallons, and will be far more stable under harder conditions than havoline...
Id get some delo 15w40 and use that instead.
