 | RON vs Octane 
 Can someone clarify?
 
 I have just purchased a 2010 GLK350 which says it requires 91 RON!
 Now according to my research, 91 RON is equivalent to 87 Octane which is regular in N America.
 
 When calling MB Canada, the unhelpful gentleman explained that all MB in Canada require premium and would not explain any further.
 
 I know it can run on 87 but do I void my warranty or cause any damage?
 
 Just to be clear, I will put in whatever is required but if I can spend less why would I not?
 
 Can someone clarify this for me?
