0W 30 - Assist in Extreme Weather Start Up

[Tommyboy]

While at the snowmobile show this past October I spoke with a rep at the Yamaha booth regarding their inline heater which I intended to purchase and some of the -37, - 40c start up issues I had this year ( yes I have the new fuel pump relay). It was suggested to switch from 0W 40 to 0W 30, this slight difference in viscosity can be the difference in turning over the engine. Anybody heard of this before ???

It helps we do it in diesel engine for the cold but this is more to help with building pressure. Do you cover the sled when u are done riding.

Do you mean switch from 0W 30 to 0W 40 right? Isn't the 0W 40 good to like 60 below? I currently run Yamalube 0W 40.

if you have a problem starting at -40 below you dont have enough cranking amps in your battery to turn it over fast enough. when I know its going to be very cold out I bring my battery inside for the night, if not first thing in the morning. havent had any problems starting in -25 to -35 degree weather since I started doing that. 0w-40 good till past -40. its cranking amps that suffer

I'm no oil expert but the first number in 0w30 and 0w40 is the same, "0" which refers to the viscosity when the oil is cold. So I can't see any difference there. Like already said, you need more cca

Sometimes those Reps are full of BS. They just belch out information that is given to them. I heard a Polaris rep one time tell a guy not to use Ethanol fuel in his sled because it Jells up. I stopped dead in my tracks and looked at the Rep with my head cocked to the side . Shook my head and walked away. Sometimes these guys should just wear the shirt and not open their mouth.

0 weight is 0 weight. The 30 or 40 is what it will be when the oil is hot. Remember the old days when in the summer we ran 10w30 and in the winter we ran 5w30 , that was for easier starting in cold weather. Most new cars and trucks today are in the 5w20 range mostly to due with emissions and fuel economy. I think I am running Mobil 1 European formula 0w30 or 0w40. Don't remember off hand but the sled starts in - 25c easy. Don't ride when it is any colder then that unless we are on a road trip and we will make the most of it.

We typically tour northern ontario and don't have that luxury, appreciate the feedback.

Hey thanks, makes sense. Saskatchewan eh, that's cold. That poor Polaris rider needs all the good advice he can get. Cheers
