Well, my new 22RE engine in my 89 4Runner now has about 500 miles on it. It got three quick oil changes due to some early oil pressure issues, so I'm planning to make a highway adventure this weekend of about 700 miles and then changing the oil. I am currently running 5w30 Mobil 5000 and am considering switching to 5w30 Mobil 7500 next on the way to Royal Purple when I switch to synthetic.
Royal Purple recommneds at least 2,000 miles before switching, does it matter when I switch to blend?
