Is it because it's a new, clean engine? It has 48 hours on it. Or is the filter really helping keep the oil that much cleaner?
BTW, I broke it in for 5 hours on the JD green oil and JD filter it came with. Then went straight to T6 and Purolator filters. 0 oil consumption so far.
Jaymus,
I'm always amazed as well that my JD LT155's Kohler CV15 oil comes out looking darn-near like new at the end of the season. It has about 360 hours on it, and I've changed it once a season since new. It's about 10 years old now. I suppose the full pressure lube with filter has a lot to do with that. And, I don't come near the suggested 100hr change interval, either.
It gives me the feeling that these engines are light-years ahead of the old L-head splash-lubed engines of the past, and should last a LONG time with proper care.
