I started driving in 1960, well 1958 if you count the motor scooter. I used Pennzoil back then, you know the kind people used to say caused sludge. Any way I used either Pennzoil or castrol GTX for the next 40 years with absolutly no sludge what so ever. But I have always maintained my cars and trucks really well. I have used synthetic for the past 10 years.
Now I have always used synthetic in my 1995 Cub cadet. It has a Kohler engines and runs as good as it ever has.
Just my experience
This POS engine has gone over 200 hours (one season) w/o a change. I have even been cheap and changed the oil, but not the filter. The current fill of Delvac 1300 is holding up really good. I can prolly go 200+ hours on it. Trick is keeping the fins clean. The mower will fall apart, before the engine does. The floorboards are rusting pretty badly.
