Cub Questions

Oil is not so critical: SAE30, SAE40, 10W30, 10W40, detergent, non-detergent. It's all good. As long as it's a good quality oil, not some cat's #1 in a bottle, you can't go wrong. Non-detergent oils are all but extinct; every oil has some detergent in it. I personally use Shell Rotella T SAE30 because that is what is available and handy.

Wiring diagram is in the manual.

Some would argue for multi-viscosity oils, but that's just a preference. Myself I use straight 30 in my tractors.

Only thing I'd toss at you, is consider getting a non-detergent oil (it's available, but you may have to ask for it) if you've got an older engine that may have significant crud built up in it. You don't want that stuff breaking loose on you.

If you're confident the engine was maintained well and has been run reasonably regularly and should therefore be reasonably clean inside, I'd recommend a regular detergent oil in straight 30.

This time I put in Delvac 1300. I chose it because its a diesel oil and should have more detergents, its also a 15w40 oil and should leak less. The downside is that in cold weather I'm always careful to make an easy slow warm up so that thick oil gets moved around. I would not use this as a winter oil unless I was using a real good block heater or two.

So the Delvac 1300 stayed in until fall, this tractor doesn't get alot of use so that was maybe 32 total hours of use on that oil. Now we're back on the change it in the fall pattern using Delvac 1300 which I bought 5 gallons of.

At some point I'm going to switch to Mobil 1 15w50 and do some oil analysis. I suspect I could go 2 years on an oil change with that oil but I'm not sure. The big reason for using that oil is because I use it in almost all my other stuff (diesel car and 2 motorcycles) so I could save not inconsiderable money by buying a drum of it. Plus its nice to have exactly what you need hanging around when you need it.
