Mudge Posted March 13, 2003 Share #13 Posted March 13, 2003 I actually run 87 octane in CA.I burn about 15 gallons a week, so I save about $3.00 a week. That is about $150 a year, not a big deal.Some people insist carb cars should run minimum on 89 or even 91. Link to comment Share on other sites More sharing options...
tttz Posted March 13, 2003 Share #14 Posted March 13, 2003 When i used 87 octane my stock 240 z would keep running for up to 30 seconds after i turned it off. I think that is called "dieseling". please correct me if i'm wrong. I read on this site somewhere that higher octane could fix the problem, so i switched to 91 and now it is fine. I haven't noticed any performance increases, but it is nice to have the engine stop when i want to get out of the car. Do you think i could switch back to 87 and not have the dieseling problem?i have heard that 89 octane is a mixture of 91 and 87. i have no idea if it is true or not.-Ty Link to comment Share on other sites More sharing options...
Mudge Posted March 14, 2003 Share #15 Posted March 14, 2003 Dieseling is correct, it can occur from leaky carbs and mine does it with any fuel I use. I have dual DGVs. Link to comment Share on other sites More sharing options...
Stryder Posted March 14, 2003 Share #16 Posted March 14, 2003 When I first got my Z it was dieseling. I think it was Mike that told me to lower my idle, it was at 900!, I droped it to 800 and it diesels no more. Link to comment Share on other sites More sharing options...

Leeroy Posted March 14, 2003 Share #19 Posted March 14, 2003 I rarely post just for the sake of it (hence my small amount of posts), but that was a classy reply Bambi!! Link to comment Share on other sites More sharing options...
