I called it the wrong oil because it stopped the pipe in a short time.
A bit hard to see but if you look close it’s about 95% stopped up.
Several big pieces of crappy spooge build up fell out when I took the pipe off.
A guy asked me to look at his engine because he said the power was low.
Told me it was 8 stroking…. Went beyond 4 stroking. Too much pedal assist to get up to speed.
I’m hoping to clean it all up and put him on full synthetic.
