Well I'm sure we want them all to be mobile to differing amounts at differing temperatures ;). I think I've seen enough bottles with API SN on to not be too worried. It's in a lawn mower also so there's probably even a little more leeway!
Hi All
Did my research but have managed to get a bit lost. I've just used some Mobile 3000 Super formula P in an API SL min application. I thought it was to spec but just checked my bottle and it has C2 specification.
Very confused I checked online which confirmed C2 on UK sites but API SN on...
