have a new kubota Z726X with a 24 hp kawasaki FX801V ? on it. manual says to change oil and filter after first 8 hours use. also to take it easy on the machine during break in period. back in the day, waaay back, when rebuilding engines for autos, we immediately ran new engine at about 3000 rpm for maybe a minute then new oil and filter. then again for 10 minutes, then repeat. purpose was to get all the burrs etc off the moving parts ASAP and out of the engine via oil changes. and to drive the vehicle fast/slow, fast/slow for even wear on cylinders via piston flex. i have asked several people why this no longer applies to new cars, mowers etc and the answer is always well oil is better now, or engines just don't need that break in period anymore. i think thats BS and defies the laws of logic BUT am willing to admit i'm wrong. so.....do i change the oil and filter now (2 hours on mower) or wait till the 8 hours is up? thanks
