- Kubota L39 TLB (With SSUQA: Skid Steer Universal Quick Attach)
After reading about Mobil 5w40 Turbo Diesel Fully Synthetic Engine Oil on this forum and further online research I decided to give it a try in my Kubota L39 TLB. My shop where I store my tractor was heated until the snow and ice sheared off my shop heater exhaust stack (again).
Nightly freezing temperatures that are quite often below 0 degrees F in the winter was a concern as most engine wear is during startups until the oil flows freely. While my shop was heated I originally was using Delo 400 Multigrade 15W-40 Oil that I've used in my 7.3L Turbo Powerstroke since it was new but after I lost my shop heater I decided to use Mobil 10W-30 CF API Rated Fully Synthetic Engine Oil in my L39.
A few days ago I drained the Mobil 10W-30 CF API Rated Fully Synthetic Engine Oil and refilled with the Mobil 1 Turbo Diesel Truck 5W-40 Fully Synthetic Engine Oil. As I was pouring the 5W-40 Engine Oil into the funnel at 5 degrees F shop air temperature I was amazed at how it flowed like water on a hot day! The first start was very smooth and very quiet and my cold engine appeared to actually idle faster and quieter than when the engine was warm with the 10W-30 Oil
This spring, when it arrives, I'm going to run my shop's overhead forced air propane heater exhaust stack out the back wall instead of through the roof. I say when spring finally arrives as I've had 6" of snow fall on the 15th of June.
I keep my battery charged using a Battery Tender and I treat my fuel with Stanadyne Performance Formula. My L39 has a block heater which I use for really cold starts.
