Second use of 20w50 in the 4Runner, this is 20w50 Valvoline Motorcycle oil more of what I bought at 17 cents per quart, this time and actually the previous time too the insolubles are fairly high, not really sure why, I have one more 20w50 test I'll post next. Oil was in use for 3,052 miles total vehicle miles 263052 at the time of the sample.
