I have a triumph 1700 Tbird and i want to start using 10w-40 synth. But bike oil is so expensive i thought i'd inquire about this very inexpensive oil (especially for a full synth) because it seems like a lot of people like it. But the full synth rotella only comes in 5w-40 and i wonder about the 5w cold stat and wonder if thats something to worry about. I live in a warm climate and don't ride in anything but pretty warm weather, 60 and above. But when cold starting i wonder about 5w....could it actually be BETTER in my climate since it would circulate better on cold starts? Or would the viscosity be too un-protective and over ride the benefit of flow on cold starts? So that question and also your thoughts in general on this oil.
