Good question.Changing the oil and filter every year does seem excessive. We would never use that low mileage intervals with our cars/trucks. Also, the synthetic oil is of the highest quality. I have changed oil and filter every year since 2010, but not for this season. I will now change every 2 years.

 

Every year for me, About 2500-3000 miles. For what it cost to me it's good insurance. Factory recommends also..

 

I change mine every 2,000 miles as the manual suggests to be sure my Cat Care won't be denied. Not that huge of a job on the TZ1, and gets it inside the shop mid season for a good once over including grease, ski alignment, and track adjustment.

 

I feel exactly the way all of you feel...... mixed bag of thoughts. Thanks for your replys, Ray:wacko:

 

every year on mine

 

Once a year and that's in fall. I do it even it sled goes 100 miles. Oil will "gather" moisture during the summer months, so why risk leaving it in? Like AP said, cheap insurance.

 

This has always been my frame of mind..... I do own a motorcycle and boat as well. I wouldn't give an oil change a second thought to them due to condensation from cold storage. Never took into consideration that oil would condensate in the summer. Thanks, Ray

 

What about keeping the acidic oil in the crankcase all summer?

 

I perform all my maintenance in the spring. I store both my sleds on lifts and run them at least once every two weeks. Idle up to temp, run track forward/reverse. Why? Mainly to help keep the drive bearings from sitting idle/drying out along with distributing oil throughout engine. Right or wrong, it's worked for me. Both sleds have over 5000 miles on them. So far, so good. Ray
