I have a 73 2.0L basically stock with hydraulic lifters and a mild cam. I am curious about what type of fuel (octane rating) you guys run. It runs ok on the 87 but I saw a sticker that says 91 recommended so I have been running 92 octane but cant really tell a difference.
I am also looking for oil recommendations type and weight, as well as transmission fluid recommendations. I want to use my car for light auto-cross and it is a semi daily driver. Thanks! |

Deja vu... I was just at Pelican. (IMG:style_emoticons/default/tongue.gif)
The sticker says 91 RON, which is not the same as American 91 octane. These things run fine on regular! If you get pinging and you are not running a high compression engine, then the engine needs tuning (starting with timing). Premium fuel is a waste of money on a stockish/mildly built engine. For oil, I run 20w-50 Castrol. It's been serving me fine for >140,000 miles. If you want something more special, use Brad Penn oil. In the tranny, use 80w90 GL5 (NOT GL4) or Swepco 201. |
