Oh Dear here we go again. How to Start to unravel the above post.The Coltri Icon MCH-6 manual says...
1. CHECK the oil every 5 hours.
2. CHANGE the oil every 50 hours or annually.
50 hours at about 3 fills per hour is about 150 fills per oil change. The sump holds .6 liters of oil. Filtertechs sells oil for $26 per quart... Which translates to about $16 per oil change. $16 divided by 150 fills is about 11 cents per fill.
One quick answer would be If you do take SurfLungs advise here just be aware that
SurfLung is advising you use Filtertech cheaper Seco Lube 500 oil at $26
While Coltri supply their own oil the Coltri ST 755 at $45
Now you can take SurfLungs advise above or you can read the Coltri manual
And if you do it states quite clearly:
WARNING: Maintenance and repairs must only be carried out using original spare parts.
AEROTECNICA COLTRI SpA cannot be held liable for any damages caused by failure to observe this rule.
You just can't have it both ways. Iain
