Hi all. I just purchased a brand new Kubota GR2010 lawn tractor powered by a 20 horsepower twin cylinder Kohler (pressure lube with a spin on filter). Although this tractor is brand new, it is a 2008 model, so my guess is that the factory fill oil has been sitting in the sump at the dealer for a year or more.
The Kubota manual states that the initial oil change should take place at the 50 hour mark. I am having trouble with this due to the fact that this oil is already a year old. On the other hand, this tractor only has a grand total of 3 hours on it.
I should state that cost is not deterring me from doing the initial oil change early. If I had my way, I would have done it already but I thought I would ask the experts here first.
So, I have purchased a brand-new NAPA Gold filter for this engine, and have available the following oils if I proceed with this early oil change:
1. 10W-40 Amsoil Motorcycle Oil (synthetic)
2. 10W-40 Mobil 1 4T Racing Motorcycle Oil (synthetic)
3. 10W-30 (30) Amsoil Small Engine Oil (synthetic)
My plan was to change the oil right away using the NAPA Gold filter and one of the above oils. Then, I was going to do it again at the factory-recommended 50 hour mark with another new filter.
So, my question is: Should I proceed with this early change? Is this engine too new to run synthetic? (Mobil 1 says no, but I am not convinced)
Again, this isn't a cost question. I just want to make sure that I break this engine in properly. If it costs an extra 30 bucks to do it in an optimal manner, then I am happy. I just don't want to introduce synthetic too early if you guys figure I shouldn't.
I thank you for your suggestions in advance!
