I read somewhere that newer eldos can use regular fuel as opposed to premium. Does anyone know what year that began? Also, I read somewhere that northstart engines that are made for premium fuel can use regualr without adverse effects. Thank you.

The year was 2000. Yes according to resident expert "BBobinski", no damage shouls occur. Maybe a slight decrease in performance, if you always drive flat out.
In 2000 they lowered the compression ratio to alow regular fuel. The pre 2000's "recommend" premium but the Northstar has a very effective knock sensor and will run quite well on regular. It will sense a spark knock long before you hear it and retards the timing appropriately. In theory you will loose some performance but I have switched to 87 over 2 years ago and have noticed no degredation in performance or fuel milage. If I were going to race it I would use 93.

With the price of gas up, my dad apparently is putting 87 in mom's '99. I drove it the other day to change the oil and it pinged like crazy. Gas card was in the console so I topped it off with 93. :D
:coolgleam i've swicthed to mid grade with a little ping and it performs better than the lower emission refomulated fuel's here in texas.
A lot of you people suggest using 87 octane. TRIED IT---DON'T LIKE IT----for the extra $3 or $4 per tankfull I will go with the 93 Octane. Personally, I think my Eldo runs 100% better with a good brand name premium fuel. To each his own, I guess.
