Re: [MBZ] compression ratio 300SL
Harry - OK I don't buy that the MAS will be affected for the reason you gave, but I'm not sure why the cats would be affected by a lower octane either. Neither grade has any lead, and the only other thing that I've heard that would poison the cats is too much hydrocarbon. Why would the computer retarding the timing a bit, per the knock sensors, cause that? Or is there something I'm missing. Please edumicate me.

Re: [MBZ] compression ratio 300SL
Prior to 1972 ALL Mercedes gasoline engines delivered to the US required
91 octane, between '72 and '85 87 octane fuel was fine (for US delivered
cars). Starting in 1986 all models except the '86 190E 2.3 required 91
octane ('87 and later 190E 2.3 required 91 octane too) and that is true
thru 2000 (I expect the 21st century engines require 91 too, but I don't
have official papers that say so!

Re: [MBZ] compression ratio 300SL
Hi Marshall,
I bet you do have the papers that say so...I would guess that if you
compare compression ratios, those years with lower octane ratings should
have correspondingly lower compression ratios.
Just speculation but sounds very logical, at least to me.

Re: [MBZ] compression ratio 300SL
Compression ratio is the biggest factor in octane requirement..Higher compression = more chance of preignition and dictates use of higher octane fuel Ask any performance engine builder if an engine with higher than 10:1 compression will require high octane to keep preignition to a minimum. Timing is the next most relevant factor.

Re: [MBZ] compression ratio 300SL
Detonation occurs in the combustion chamber, opposite the spark plug. As the flame front burns across the chamber, heat pressure builds up until the remaining gas explodes. With higher compression, you already have more stored heat in the charge, making detonation more likely. Higher octane gas burns slower than lower octane gas, reducing the pressure heat. This allows you to run higher compression. Timing can also help because reducing spark advance delays when the spark starts puts the piston further down (lower pressure) when the flame front is moving across the head. Compression ratio is important but head design is just as important. Chrylser's Hemi engine runs higher compression because of its domed combustion chamber centered spark plug. The design has a very short flame front because it travels from the center out. A wedge design can't come close because the flame has to travel from one side to the other (twice the distance), giving more time for detonation.
