agree, not agree, doesnīt matter because we didnīt made engines lifes longer because of pre-heating or something else magical treatment in the last 10 years.
2005 i had an RB WS7II, it ran like crazy for about 50 liters with 1 x maintenance.
no preheating, run-in made by me in the winter with zero skills about anything, bad tuned often.
best engine, lived long.
every brand/manufacturer has tolerances, 2 possibilities:
1) you got a good engine
2) you got a (more) bad one, which even at OS happens
3) nothin you do will change that
once i understood this, i stopped buying 500 dollar engines, because itīs no guarantee something will be better or holding up longer.
thereīs 2 reason for preheatin:
fresh engines start made easier because of that pinch...
used engine warm-up time safer when youīre in a hurry at big races or something
