( funny sincemy friends bikes and mine all call for high api ratings and since all api ratings supercede each other) And all the new API requirements all the other oil companies like motul are meeting for motorcycles are actually making there product worse since they dont have zddp - and will not protect your bike at high rpm. (funny .. because Rotella meets SN and diesel engines to my knowledge diesel engines loove zddp- also funny since my motorcycles effeccient driving light doesnt even turn off till 9000 rpm and is built to tolerate high rpms on a super regular basis) ... that wasnt even the complete email the whole thing to type again would insult my intelligence and i dont really want to go there. I've been dealing with these guys for so long and i've never had a problem. my money will support another american business from now on. not only not factual, but aggressive marketing. something tells me before big oil companies took over them things were diffrent.
To this i say - why on earth did you upgrade your automotive line of oils then?
...not listening anymore.
I will give it to them though - thats aggressive marketing. this is the good ole way of marketing in the west. something tells me before big oil took over them things were diffrent.
I humbly submit my resignation from Redline products
Regardless of redline and API certficiation, I'll try to explain what they are saying, as it makes sense to me.
API is indeed a car engine rating. Some motorcycles without shared sumps might actually call for an API spec, but others will likely ask for a JASO spec which is indeed a motorcycle spec (or rather wet clutch/shared sump spec). Rotella is exempt from the SN spec limitation on phospor as it's main spec is for a diesel engine. That's just how the spec is set up. the first API spec listed is the one that's followwed, and the others are only partly followed where they don't clash with the first.
I'd be interested to see the rest of the mail though. I have no relationship or contact with Red line, btw
