Hello guys/girl
I have an important question that I need to have answered
I own a 13y old Ducati ST4,for the unfamiliars, this is a 2 cylinder 4t 'L' shaped V-twin of 916 cc (large bore, small stroke i think)
I only have it for about 6 months now, so only drove it during winter time.
At the end of the winter I gave it a large service during which I off course changed the oil.
after consideration I used 5w50 instead of the prescribed 10w40.
at first thing were oke, but after a while i noticed it starting to have problems with maintaining low rpm's and would sometimes stall at trafic lights at arrival.
this slowly increased over time in frequency and severity.
reasonably suddenly it stopped maintaining stationairy rpm (1250) at all..
and started to smoke.. blue.. and really fouwl irritating (eyes and lungs) smell
it runs well at rpm's higher than 1500..though.
anyway.. I feel like the 5w50 is to thin.. so it doesn't seal enough and therefore burns oil, leaks gasoline in the oil (thinning it further) and looses compression..
now my question is.. and this is the important part for me..
!!! Can this happen only by the difference of 10w40 and 5w50 !!! of is there an other cause!!! (or did this lead to another cause???)
