Hi. I just bought a C50 and the head mechanic said I should put in premium. My manual says I can use regular grade. What do you use? Suggestions.
Thanks.

 

I"ve tried both octane's and i havent noticed any difference in anything, I use 87 octane and am fine with it.

 

I run 87 octane

I have a C-90T (2008)[sm=groupwave.gif]. Bought it in Aug 08 and I have tried both reg and premium. I feel I get better performance with premium, even though it runs very well on reg.[sm=insomnia.gif] I have about 2000 on it to date and I really love it. Almost as much as my wife.

Now I am looking for travel packs.

Gotta go, see you there.[sm=smiley35.gif][sm=devilangel.gif]
