Re: [FWDLK] Octane

Hi Tony,

The good book says…the D-500 engine requires premium fuel.

That good book is your car’s owners manual, on page 19.

My personal experience is the MPG gets better, and performance also.

Just be careful with the additives. They might eat up your rubber parts, like fuel hose and glass bowl filter gasket.

Best regards, Jim

Hi All,

I have a 57 Dodge with the D-500 Hemi engine in it, and I’ve been using Unleaded Premium with a 93 octane rating. It runs just fine, but I’m wondering if I am spending extra $$ I don’t need to. Should it run equally well with lower octane? Considering I drive it about 200 miles a year at most, I guess it doesn’t really matter, but is higher octane really better for this engine?

A local station has begun carrying 110 octane, and some have suggested I even switch to that. Since I’ve never driven the car faster than 65 mph that I can remember, it’s not like I need any more power.

Thanks,

Tony Boatman
