About ready to get the tiller Troy built Super Bronco out for the spring and need to change the oil.
I'm debating between a Synthetic and Rotella which would you reccomend?

I run Rotella in all my garden equipment and my wood splitter too. I change everything at the beginning of the season since most have the hours or are near the hours to be changed, and I probably still would even if a had used synthetic. I don't see that the money spent on synthetic would be worth it. Just my opinion and way of doing it. Gary

With the low number of hours most of us put on our personal tractors I would think l that a good brand of oil would work just fine. On several of the golf courses I worked at we used 15W49 AMS Oil in all four cycle gas and diesel engines since most pieces of equipment would get over 400 hours a year and several in the 500 to 750 hours area.

I would never recommend cheap oil in any engine that spends most of its life running at wide open throttle since the oil in an air cooled engine is used not only to lubricate the moving parts but also to aid in reducing the temperature of the metal by convecting the heat to the cooler air swept areas.

That's an easy one. Use synthetic Rotella.
They have a "T-5" oil that is a synthetic blend then their "T-6" is a full synthetic 5w-40.

Yep. Synthetic oil is a really a must for air cooled engines. The difference in 20 degrees could mean oil that has broken down, or still up to the task of lubricating and preventing sludge.

I run 30w non-detergent in all my motors without oil filters. With no filter, detergent oil will pick up the crud in the oil & keep circulating in the engine. I use 20w inwinter in snow blower. I tried
10w30 once & when I drained it hot to change it, it was so thin it looked like diesel fuel. That's MHO
& I'm sure a lot will disagree but I get long life from my air-cooled motors.

15/40 Rotella or other brand of good diesel oil. 5w/40 in the winter. All my equipment does stay in a warm shop.
I change it quit often on the non filtered engines to remove the dirt from the crankcase.
