bumpstop325 0 Report post Posted May 7, 2005 (edited) Ok, this happened to me the other day. When i filled up at Shell in palmy, i must of got a bad dose of 91 octane. After this, i was driving and the car started backfiring hard out, when i put any load on the engine. It was just wasnt drivable but when i went to take off. The car just dies or goes very slowly. Starting of the egine takes a few more seconds to turn over if at all. Another sign. To get the water out of you tank, you can do two things. One, drain the fuel tank completely and wasted gas, or Two, buy a bottle of METHS (the purple stuff) and stick it into your fuel tank. With a fuel tank you can put up to 3L of meths without affecting the engine. I'm not 100% on how it works. I have been told that the meths bonds to the water, making it a more flammable mixture than just water and fuel. This took me a few days to find the problem but at the end i only spent $4.35 fixing the problem. Edited May 7, 2005 by bumpstop325 Quote Share this post Link to post Share on other sites
Tommy 0 Report post Posted May 7, 2005 You run your car on 91? I only put in 96, runs way better. My old dx used to spit tacks wen I put 91 in her. Quote Share this post Link to post Share on other sites
stolen 0 Report post Posted May 7, 2005 yeah this happened to me too... i was under the impression that it was cos of the 91 i put in it. This was just when i got my car... same symptoms plus start in the morning and it just dies and i floored the accelerator and it sounded like one of those rotary cars..... took 3 fills of 96 and it was all good after that...guess the bad fuel finally went off.... :finger: Quote Share this post Link to post Share on other sites

my_e36 43 Report post Posted May 7, 2005 For some reason, when I use 98, I actually got WORSE milage compare to 96. I don't know if it's just me or what. This happen to my e36, Civic, Accord and CRV. (yes, I am an ex-Honda freak) Quote Share this post Link to post Share on other sites
Guest Andrew Report post Posted May 8, 2005 For some reason, when I use 98, I actually got WORSE milage compare to 96. I don't know if it's just me or what. This happen to my e36, Civic, Accord and CRV. (yes, I am an ex-Honda freak) probably cause it doesn't burn and runs rich. I get awesome economy on 96 - 91 is horrible economy.

kiwi535 538 Report post Posted May 8, 2005 yes i have heard this meths trick too..the alcohol actually absorbs the water somehow and it is "burnt" along with the petrol/alcohol mixture Quote Share this post Link to post Share on other sites
bumpstop325 0 Report post Posted May 8, 2005 all the guys at work were shocked that i just shoved meths in my car and just drove off, like i normally do . Because wheni got into work some of theguys saw me push my car into the work carpark. cause it stalled in the middle of the driveway and couldnt get my car started again.

m325i 709 Report post Posted May 8, 2005 Wish I could get 98, it kills me. Dirty 96 Shell only. 98 is noticable better than 96, with some placebo Quote Share this post Link to post Share on other sites
petone 0 Report post Posted May 8, 2005 i don't think 98 is worth the extra over 96, my car doens't like 91 at all either. Quote Share this post Link to post Share on other sites

Carl 3 Report post Posted May 8, 2005 (edited) Who here actually runs on 91??? When I first go the car I ran 91 since my previous cars used it and I wasn't sure. Wasn't till I ran my first trip north to Hamiltron that on one tank it only got from Welly to Putararu, that wasn't even 500kms...the next trip using 96 it got to Hamiltron no probs, 550kms+ I'm now getting 12km/l on trips having the manual and tall diff Edited May 8, 2005 by ///Carl Quote Share this post Link to post Share on other sites
MattA 164 Report post Posted May 8, 2005 I don't think I've ever put 91 in a car... I 98 mostly does make a difference although it coud do with a good tune up (no motronic) cheers Matt Quote Share this post Link to post Share on other sites
CaM 0 Report post Posted May 8, 2005 98 rules mega in high comp cars, I noticed huge differences in "performance" jap cars more than anything else, due to them being tuned for jdm 100octane.... Laurel was better on 96 marginally, but driving it to work I just ran it on 91... worked out cheaper by a small margin, plus I hardly drove it most of the time so yeah......

Tommy 0 Report post Posted May 9, 2005 Most of the mobil's and a few BP's stock it in welly. Mobil does that synergy system e.g 91= synergy 1000 98= synergy 8000 Quote Share this post Link to post Share on other sites
rxsumo 33 Report post Posted May 13, 2005 Silly Question , but did you ring the Shell Technical line, and report the problem? These guys keep a check on the petrol going into the service stations, and will respond to an issue. might get you meths dollars back Quote Share this post Link to post Share on other sites
Dnz 0 Report post Posted May 13, 2005 I tried 98 for a while, but really it just costs more. Its prob wasted on my car.. But i think there might be a degree of placebo in the sale of it.. Anyway, for you guys looking for it - BP sells it as 'BP Ultimate' - i think they list them on their website.. Quote Share this post Link to post Share on other sites
