Re: Running a ZE on 87 octane?
isnt a motor blowing up using lower grade gas a little exagerating?
My car always gets Sonoco 94Octane, 92-93 worse case if im really, really, really stuck
I always found high-octane lastested a bit longer, a gave the engine a little more kick. Never tried less than 92 with my ZE, and i never wil
I wanna put a sticker to replace my "Unleaded Fuel Only" with "High-Octane Unleaded Fuel Only" sticker

Re: Running a ZE on 87 octane?
Actually, if you re-read that owner's manual you will see it states 91 octane for the K8.Originally posted by UoMDeacon:
I've always used 87 in my V6, and have never experienced knocking. The manual states 87 is fine.

Looks like 87 to me for the 1.8L V6

Re: Running a ZE on 87 octane?
interesting.....on page 3-2 of my manual it also says 91.
(sorry no scanner)
"Your Mazda will perform best with regular unleaded fuel having a research octane number (antiknock index) of at least 91 [(R+M)/2 method, 87]

Re: Running a ZE on 87 octane?
This is a method of measurement issue. Lots of countries use RON (Research Octane Number) measurement, and the recommendation in my (K8D) Owner's Manual is 90 RON. This is the same as about 86 (R+M)/2, which is the measurement system in N. America. So 87 is fine in the US.
By the same token, I think a KLZE in the UK (if I could get one
) would need 98 RON (about 93 to 94 on the(R+M)/2 scale).

Re: Running a ZE on 87 octane?
Yeah, 87 works, but you get considerably more ping than 91.
The K8 still uses 9.1:1 compression, which is moderate, 91 would still be best.
My manual definately states 91, but it's weird there are some discrepancies between the years or models.

Re: Running a ZE on 87 octane?
Aiden,
Could you check whether your manual says 91 RON. If so, I expect that's 87 at your pump.
However, if it says 91 (R+M)/2, it would be strange.
For the avoidance of doubt (as they say
) here's a link which makes things clear Octane Ratings
and one for if you get REALLY interested Octane Measurements

I use 91. 87 wrecks the plugs and sounds really bad going up hills, I've found.
