 Oil Viscosity

I just bought a used Kubota G1900S mower. The oil fill cap says to use 10W30 oil. I can not find any 10W30 oil that is approved for diesel engines. My local Kubota dealer says to use 15W40 oil. What gives? I hate to use oil that is heavier than recommended by the manufacturer.

15W40 is fine unless you are planning to use this tractor in sub zero temps. 15W40 is good for temps from about 0 f to about 120 f. 10W30 is good for about -4 f to 85 f. 15W40 is a good all-around (all climate) viscosity.

Mobil 1 has a 10w30 rated for diesels.

Most any agricultural equipment dealer will have it. You need to look for a CD,CF or CG rating.

My NH dealer has 30 weight in 0, 5 and 10 flavours and of course 15w-40.

I think of 15w40 as summer oil and was surprised at Billy's comment. I check my Ford 1710 manual and the chart for 15w40 indeed goes to 0F.

There are some advantages to using lighter oils in cold weather. The starter spins the engine faster which makes it a little easier starting and MAYBE lighter oils get to engine surfaces faster in very cold weather. I use lighter multi-grades year around because it can get very cold here and I can avoid operating the tractor during the few really hot days we get during the summer. The main advantage of 15W40 is for many-hour heavy-draft operations during very hot weather.

Some manufacturer specs were written before synthetics and lighter multi-grades were common so I think it's fair to say that the manual may not be the last or best word except for warranty purposes of course. Some specs may not have been updated since all the ratings Art mentioned were defined.

I would think a person would choose a viscosity for the expected temperature between oil changes. There are very few compact tractor owners who will change oil more than once a year. That being the case, you need to choose a multi viscosity oil for 'your' climate.

It is that very once a year oil change that takes me into the synthetic concept. It is the one oil that covers all the bases. It flows at -50F and is stable at +400F.
Billy, check out Shell Rotella Synthetic at Wally World for that upcoming oil change.

Thanks Mark, I believe I will. I use Rotella 15W40 now so I might as well give their synthetic a try.

If you followed the other post I have picked up about 10% milage using the 5W40 Rotella Synthetic. This is the first time I have had a noticable difference when switching to synthetic.
We did not have an easy supply for the synthetic locally until recently so just switched my truck. The temperatures are such here that the 15W40 can be used.

I did read your post, Peters. That's what got me to seriously thinking about trying a synthetic.

Thanks
Billy
