regen # 10 today @ 95.4 Hrs. I have not tried any on road diesel yet because I discovered that all of the filling stations around here are using anywhere from 5 to 20 percent biodiesel blend. With the particular engine in my tractor (V3800-CR) Kubota corp. recommends not running any biodiesel over 5 percent. The pumps just say between 5 and 20 percent so you can't be sure. I went to Kubota's web site and read what Kubota says you need to do if you are going to run a biodiesel blend. No Thanks, I will stay with the off road. My supplier told me they do not use any biodiesel in their off road fuel.
Here is a little of what they have to say
Maintenance Requirements when using Biodiesel fuel B6 thru B20:
1.Replace the fuel hoses with new Kubota approved hoses at one half (1/2) the suggested replacement intervals as listed in the Operator's Manual. For Example: If the suggested interval is 100 hours to replace fuel hoses, then replace at 50 hours.
2.Replace the fuel filters with new Kubota approved filters at one half (1/2) the suggested replacement interval as listed in the Operator's Manual.
3.When using Biodiesel for the first time in your Kubota equipment, replace the engine oil with new Kubota approved oil and filter and follow the service requirements listed in the Operator's Manual.
Here is a link to the page on Kubota's website.
https://www.kubota.com/service/BioDiesel.aspx Be sure to click on both tabs on this page and read the whole article. This is getting more confusing now. Especially if the Govt. mandates the blending of Biodiesel in all Diesel fuel to include off road diesel. If they label it all showing between 5 and 20 percent and your tractor is not supposed to be ran with anything over 5 percent how are we going to be able to tell which percentage the fuel actually contains? The government knows they can screw some stuff up! Namely everything they get involved with.
