anyone hear ever used maxima maxum4 ultra 5w-50? any test done? any problems?
bike is a 2001 aprilia sl1000 falco(a slightly more comfortable mille rsv-same engine,for those that don't know)
it still has what i consider low miles and i live in south florida.the manual recommends api sg in 15w-50.
a little history:the bike came from the dealer with agip 10w-40.as soon as i got it,i changed the oil to motul 300v factory line 15w-50.i instantly notice the engine got "tighter" and "quieter" and felt a very slight performance drop.(of course)
my interest in this particular oil(maxima)is to restore the awesome "looser" feeling but still have a stronger film strength and ht/hs than a 10w-40 and better cooling than a 15w-50(no heat problems though).
eventually,i'll switch to 15w-50 down the road with much higher mileage.
here's what i know(or think i know)about the ultra4.it's ester based(polyol blended)with about 16% pao for seal swell(according to the guy at maxima)and is packed with an exceptional addative package.in particular,it's zinc and phosphorous seems higher than even the better motorcycle specific oils out there.(this part was proven from an independent study)(they have a extra4 which seems to have even more)
so,anybody out ther use this?
by the way,while most aprilia owners stick with 15w-50,lots of them use 10w-40 with no apparent negative effects.also,this may be a v-twin,but it's NOT an air-cooled one,like a harley.it's a twin built by rotax(with aprilias' input)with which they won WSB.
all opinions are welcome.
