I intend to do a 15K mile run on my GR86

Valvoline doesn’t recommend extended drains with any of their oils.

While that is true, they do somewhat imply it by having an oil named “Extended Protection”

Sounds like a solid warranty case to me.

I totally agree. Somehow they consider Extended Protection = upper limit zddp and a slug of moly. Extra Protection would be a bit more clear

Back when EP first came out Valvoline had a Q&A. Everyone was asking about extended drain. Valvoline has always been up front in saying they do not believe in extended intervals. Their guarantee fine print says 5k mile intervals.

why?

On my GR86. 4 Quarts Valvoline 5W-30 EP and 1 qt. Mobil 1 20W-50 V-Twin Oil. I will do a UOA every 5KI miles.
The Mobil 1 seems to do a good job.

I thought you posted that you were going to run dealer 0w20 with 2 quarts of the lucas 20w50 motorcycle oil?


You have some fascination with mixing.
