Lets see here. Today I did the break in oil change. Changed it to straight pennzoil 30wt and a longer pureone oil filter. Before anybody says anything about the straight 30wt kohler does have it in the manual for above 50 degrees. Straight grade oils are superior to multi weight oils. They do not have the viscosity modifiers that multi weight oils use and the heat and shear resistance is higher on straight grade oils. The next oil change it will get amsoil ACD 30wt. My machinist/engine builder is very well known and only does machine work and builds engines for only a select few. When you are that good you can pick and choose who you do work for and my cousin is friends with him so I have the in with him. Anyway he told me to run straight 40wt in my new 385 stroker I just built because of the reasons I mentioned above. So I figured I would give the straight 30wt a try in this efi kohler and see how it does. Also today I some how punctured the sidewall on a rear tire. 14 freaking hours and the tire is "technically" no good. But I filled it up with slime and stuck a plug down in it and it is holding fine so far. It is not the first time I have done this and it has worked before. If it decides to start leaking again I will have to try patching the tire or just suck it up and replace it. Ok with that said I got a chance to cut two bi weekly lawns today that were every bit of 10"+ deep and these are treated and VERY thick. We HATE these lawns and we used to do them every week but money got tight for these people. Anyway I cut them at 3.5" and it cut very clean and only left a little debris in a couple spots. Buzzed back across those spots and it vanished and the lawns looked like they are cut weekly. The XF1 deck would have required cutting at 4" and then raising the deck to 4.5" and going back across to clean them up. I am absolutely thrilled with this updated deck!
