The C46540 manual that I have specifies on page 9 to use the 5W-30, 10W-30 and 30W above 70 fegrees F just like the C46535 manual on page 11.
Champion's website is where I found the recommendation for using the 20W, 30W, 40W and 50W oils.
That's why I decided to ask Champion's tech-line for their latest thoughts on the oil grades.
