How about synthetic in a TZ25?

[wny770]

I bought a woods SS52 for my TZ25 and want to use it this winter to blow snow. Is synthetic a good idea for an engine with only 85 hours on it? I thought maybe the synthetic would be a good idea for the colder weather. Any suggetions as to what weight or brand to use? It seldom gets colder that 5 or 10 below here. The "usual" winter lows are in the single to teens... Thanks!

No problem with switching to synthetic. As for viscosity what does it call for? If it calls for something like a 10W/30 then you could go with synthetic 10W/30 or 5W/30 for better cold flow properties. If it's a diesel that spec's a 15W/40 then you can use 15W/40 or the other popular synthetic diesel oil viscosity is 5W/40. The lower first number is the winter/cold viscosity, the lower the number the better the cold flow properties.

Rule of thumb as I understand it is that 1 hour equals 40 miles in an automobile. So 85 hours is 3400 miles. The recommended time to switch to synthetics is about 5000-6000 miles. I switched my 1999 JD Scotts 2554 over at 6.5 hours. So as you can see I can't even follow simple recommendations. The Scotts now has over 350 hours on it, runs great, no smoke, gets good fuel comsumption. A compression test this past August on both cylinders was 185psi, and 190psi. I use Mobil 1, 15w-50 in the Kohler Command twin cylinder engine. I think you will be happy with switching over, and I'm sure you have enough hours. You may want to use a 5w-40 Mobil diesel synthetic offered at Walmarts, due to you low temps in the winter. That is what I am switching my TC48 to.

Recommended by whom?

The manual says 10W30, so thats what I'll use. I'll let her drain overnight and fill with synthetic. Thanks.

I switched to synthetic but went to 5W-30 and you will notice the cold weather starting difference.
I believe you could have put synthetic in it when brand new and had no problems. A newly rebuilt engine may want to use regular oil for a breakin period.
