On my 74 2.0L, I have MPS (Part#: 280 100 043). I am not having an existing problem with my MPS, but with today's gasoline (ethanol blends, etc..) should an MPS be recalibrated for optimum operation? I typically fill up with Chevron 91 premium.
Of course, if it's not broke then don't fix it... |

You're probably OK. Running 91 octane fuel is most likely a waste of money unless you're running pretty high compression. The correct version of your last sentence is "If it ain't broke, fix it 'till it is". 914 guys follow that one a lot.

(IMG:style_emoticons/default/unsure.gif) (IMG:style_emoticons/default/unsure.gif) (IMG:style_emoticons/default/unsure.gif) Haha! Just kidding. What's everybody running on their stock FI systems? Mid-grade 89? Or 87? Back when I had a BMW E36 M3, I once calculated that running the 91 premium fuel for a year costs about $400/year extra (assuming aroudn 15K miles/year.) I suppose that's $400/year I could be putting towards an eventual engine rebuild. |
