[quote=Suze;194362]Dunerunner - I think your costs weren't really "maintenance", other than the filer and oil, were they?[quote]
Oil and filter every 3000 mi. adds up.

I did the initial change at 500 mi. and another at 1000 mi., then oil and filter every 3000 mi thereafter. I had to buy tools to do the work and that adds to the cost initially.
