As Standard fuel was only used in all Grey Holden engines. But when the big Falcon came out they had high compression engines of 8.8:1 back in 1961 but you could opt for the 144 Low comp so you would not get stung at the fuel pump ! Holden's did not get 8.8:1 until late 1963 EH. But i do remember the MK III Zodiac did perform well for back in them days. A HQ 173 6 CYL low compression was 8.3:1 and this was running on Standard 87 octane. |

No octane checks in those days unless someone complained. Thoughtfully, Lucas provided a knurled nut at the base of the distributor to retard the timing for such an eventuality (all those Eastern Bloc countries using Russian surplus pumped from drums left over after the War)! Some of the tin-pot towns in the outback still had manual pumps where the petrol was pumped into a sight glass from underground, then released into the tank by gravity by the attendant wielding a lever graduated into whole gallons only. This by-guess-or-by-God method meant I always had to keep my jerry can partly empty for overflow, lol. I owned both the Mark II Lowline Zephyr 7.8:1 high-comp automatic new and traded it on the replacement - the XK Falcon auto 8.7 to 1 high-comp with the clear sticker on the base of the windscreen reminding you to use 'premium' fuel (obviously a US sticker as Aussies called it 'Super') - some years later (belonged to a little old lady, so low miles). Each went as good as the other. |
