Ha I know how that goes! Four years and if we weren't deployed or in the field it was loooonnnng days of sitting in the shop till 5-er-I mean "1700" and trying not to fall asleep...Nd4SpdSe wrote:Of course not, I'm in the military!Daninski wrote:Like you have anything better to do.
has anyone tried this dry gas stuff? im going to see how it does as is then ill try some "tricks" with the new o2s, im just curious on everyones opinions on what octane gas i should use?I had gutted the cat in my 91 Jeep Wrangler. Some one suggested I put Dry Gas (water remover/anit-freeze)in the tank. I put 3 bottles in the tank and it passed better than it did the first time with the cat, when it was new. I had my old emmision test to prove it. I have a friend that worked at a different emmision place, I showed him the test and told me he had never seen numbers so low.
good to know. ill be sure to run 91+ from now on... any negative effects i should look out for with this 89 octane? assuming my knock sensor is working properly, the ecu should retard timing and prevent damage if pinging occurs? the car actually has 1/2 tank of 91 and half a tank of 89 so we'll call it 90 and it should be ok (fingers crossed)Nd4SpdSe wrote:Mazda manuals apparently list using 91-equalavent octane gas (Jap uses a different rating than here in North America). It' a high-compression motor. I never ran anything lower than 91, I tried to run 94 religiously.
The higher the octane level, the more the fuel resists igniting when compressed. The higher the compression, the higher octane fuel is required so that it doesn't pre-detonate under the compression cycle, causing pinging or worse, detonation.
It'll retard the timing to prevent damage (really should only be a major issue when pushed hard) but if your ECU had to retard the timing, you'll fail your e-test since it's not combusting properly.mikeinaus wrote:any negative effects i should look out for with this 89 octane? assuming my knock sensor is working properly, the ecu should retard timing and prevent damage if pinging occurs?
Japan uses a RON octane rating system, while North America uses AKI, which is (RON+MON)/2)._-Night-Shade-_ wrote:91 in Japan is 87 in North America so don't let the manuals fool you. I've been running 87 since my swap without any issues so don't waste your money!
). I find using high octane fuel on the hwy greatly increases the mileage I get so I think the cost is off set by increased mileage. Igor you spend too much time p*ss assing around town to know any better. 
That has to be some kind of retort record. I barely just posted that and you came back all most immediately.
