Hi everyone I race a 1970s Honda CB350, and am trying to find an ideal oil for my situation
The engine is a overhead cam design, rocker to valve tip, and is notorious for eating cam lobes / rockers should you stray from a good oil / breakin procedure
It runs anywhere from 220*-310* oil temps
Raced for about 30minutes at a time
Usually ambient temps range from 60*f-100*f
my go to oils are:
Rotella t4 15w40 for break in with a dash of ZDDP lucas addative
Amsoil Metric 10w40 for regular race duty
I have also tried mobil 1 4t ( good results? cant really say any wear occured from it, shifting seemed typical )
I am eyeing some other alternatives to amsoil as its hard to find in a pinch, and cost prohibitive to change the oil as much as I would like to
I like to change the oil every 2 race weekends ( a total of 6 days of race duty ) and I run an inline spin on filter ( usually KN )
Any thoughts on alternatives? what you think the "best" choice would be for my application?
Im looking at the full syn valvoline 4t oil, but have no experience with it so im weary, also looking into motul 300v, maxima extra 4
Redline is considered the gold standard by vintage racers but boy oh boy is it expensive.
Also, if anyone could specify a target oil temp for starting operation, and a cutoff point or turn the **** bike off its too hot id be curious to know what that is,
Thanks for any advice you may have to offer! Im overwhelmed with choice!
