Just a quick mention here, as I never hear mention of it on automotive forums, but for my older flat tappet engines where I need a good additive package containing ZDDP...... And even for our newer roller cam engines which were originally broken in with dino oil and tend to leak and burn oil if even a synthetic blend oil is used at regular oil changes...... Let alone a full synthetic...... For the past 10 years, I have been running Valvoline 4-stroke motorcycle oil in these engines with excellent results. Additive package is similar to same weight VR1, only not a synthetic base.
This stuff. Looks like they have it in blue bottles now. The ones I have stashed here are black bottles......
