2008 ISL 425 Cold weather starting

Planning trip out of Michigan mid January, I'd guess the ambient temps to be 20 ish then.

I have left the MH full of fuel with full bottle of Howe's additive in 150 gallon tank, took the MH on a run to be sure new fuel is through the ISL and through the Onan generator before shutting it down last month

Motorhome is parked in an outdoor storage lot, no 120V power to use.

I do not have a 120V plug in block heater but do have an Oasis system with block heating option

What's the opinions on:

A, cycle the igniton key a few times and start the engine.

B, hauling out a small gas generator plug in the MH run it overnight plugged into the shore cord and run the Oasis that will pull 8 - 10 amps and use the Oasis block heater, also will keep the house batteries charged

C, run the Onan diesel generator overnight and Oasis block heater

D, set the AGS to come one when the house batteries reach 12.0VDC use only house batteries and the Oasis overnight

I'm assuming it will take 8 - 10 hours to warm up the block from 20 degrees F. for an easy engine start

Thanks for your opinions

Rich

All options would work if there were no problems. I would opt for C... turn block heat on as well as interior furnace. Since you have 2 elect heat elements, you good get by with that rather than using the Diesel option, you use both if you are not sure. This would also keep batts topped off for the beginning of your trip (Im not a fan of using the alternator to charge a large bank of house batts).

20F temperature is not that low, for starting your DP without heating the engine. I have not yet used my block heater and I live close to Niagara Falls. I have started my DP below -5F without any problems. I keep my batteries in good shape and charged. The warm up is shorter if you use your block heater. I would use a block heater if the temperatures were below -22F for a couple of days.
I think it is much a matter of choice and comfort you have in your equipment. Myself I work in the construction field were we often don't use block heaters. We do a lot of preventative maintenance to ensure the equipment starts every time. One great item to use before the temperature gets cold is fuel conditioner.

Living in northern Mich all my life, in Jan the temps can hit -20. Let your conscience be your guide on what procedure you use.

If you have a light weight conventional oil or synthetic oil in the crank case you should be fine but it would still be easier on the engine if you'd turn the block heater on for a couple hours.
It kind of hurts when I see big diesels trying to fire up in brutally cold weather, stuff can break when it's cold.

With many years of cold diesel starting experience, I can first say that each engine seems different. One will start, the next identical engine will not. Such is life.

Your list, my replies:

A. No need to multi-cycle usually. Engine has grid heaters in the intake, so a couple of cycles may be needed. Just realize that each cycle drains more from the batteries leaving less for the starter motor.

B. Would work, but seems like a PITA to me.

C. If the engine would not start, likely the Onan generator won't either. But a couple of start cycles may do the trick.

D. I once had an auto-start that also sensed temperature (of the engine) and would start, warm up, then shut down the engine.

My thought: I'd go with A. My rig (ISC) seems to start right up in the cold, and run smoothly at that.

Thanks everyone, this is my first winter with the ISL and don't want to hurt her!

Oil is 10W-40W in both motors, manual chart shows good for well below what I expect the temps to be at start up in the 20's here in GRR

I plan on a practice run around Christmas, starting with A, and down the list as needed

Run the generator for 30 minutes to allow the batteries to warm up and be sure to press the aux start button to help when starting the engine. Leave the generator running during the process to provide as much DC power as possible.

2008 ISL 425 Cold weather starting

As mentioned no glow plugs in the ISL so double cycling the key only reheats engine air grid heaters). I start the hydrohot (oasis) diesel burner on good house batteries and circulate engine preheat (engine antifreeze loop) for about two hours. I have taken engine temp from 5F to 70F in two hours (coolant temp readout on my Silverleaf system, reads ECM data)

I just returned from a trip to Memphis and the temps were 'only' in the 20's, but other than making sure nothing 'extra' was on and/or plugged in when starting, ours fired right up.

Now both my engine and genny have glow plugs so they did take longer than normal time to warm up... but I just started the genny first, let it run for 10 minutes or so to stabilize and generate power, then used the battery boost to help the glow plugs pre-heat the engine before starting it (probably didn't need to, but I did)

John, are you sure your engine has glow plugs??? Just curious. My Cummins has a grid heater.
