OldsmoBeast Posted January 5, 2003 Report Share Posted January 5, 2003 I changed my oil about 2 weeks ago and i used Mobil 1 synthetic for the first time. Recently, i've noticed that (among other issues) my oil looks clean but smells DEFINATELY of gasoline.....what could this be?! Thanks Quote Link to comment Share on other sites More sharing options...
toastemcutlass Posted January 6, 2003 Report Share Posted January 6, 2003 Hey saw your problem and was wondering if one the car runs fine and two how many miles and if you have used synthetic before. If the car is not running right its possible that the car for what ever reason is running way to rich, I incounterd that problem with a 4.3 liter blazer turned out the fuel presser regulator went nuts . good luck Quote Link to comment Share on other sites More sharing options...
ctx46 Posted January 6, 2003 Report Share Posted January 6, 2003 you might have a leaky injector, of some sensors are messing with the ecm to make the fuel tables way to rich.... and SES lights? Quote Link to comment Share on other sites More sharing options...
OldsmoBeast Posted January 6, 2003 Author Report Share Posted January 6, 2003 could be.....hmm...it never gave me a light but when i checked it threw a code 33, MAP sensor high voltage, in my car's case.....but i just don't know. I've nver used synthetic in my car before. Quote Link to comment Share on other sites More sharing options...
OldsmoBeast Posted January 6, 2003 Author Report Share Posted January 6, 2003 as far as miles......it's 121,500 KMs.....so prolly around 73,000M? Quote Link to comment Share on other sites More sharing options...
toastemcutlass Posted January 6, 2003 Report Share Posted January 6, 2003 In my car I use a synthetic blend cus I heard that after the motor has a cetain amount of miles it can start making things leak. try pulling out the dip stick out and take a lighter to it if it starts fire right away it is gas and you probably got a problem but it might be normal, castor smelled like fish in my old car so it might be normal, like i said i'm reaching for straws Quote Link to comment Share on other sites More sharing options...

Brian P Posted January 6, 2003 Report Share Posted January 6, 2003 put a lighter tro it? what???? where did you hear this from? Quote Link to comment Share on other sites More sharing options...
ismellrealbad Posted January 6, 2003 Report Share Posted January 6, 2003 i dont know where he heard that from...its not the smartest thing to do, but i guess it would accomplish the goal :? Quote Link to comment Share on other sites More sharing options...
OldsmoBeast Posted January 6, 2003 Author Report Share Posted January 6, 2003 doesn't oil burn too? i assume synthetic wouldn't then? Quote Link to comment Share on other sites More sharing options...
RedZMonte Posted January 6, 2003 Report Share Posted January 6, 2003 doesn't oil burn too? i assume synthetic wouldn't then? NO, don't burn it.. it will go boom. you probibly have a leaky injector seal or a bad o2 sensor. something eather leaking or causing you to run VERY VERY rich. look near the injectors to see if one is leaking and pooling fuel anywhere on the lower intake manifold. then change your O2 sensor and make sure your not running VERY VERY rich. any codes?

OldsmoBeast Posted January 7, 2003 Author Report Share Posted January 7, 2003 like i said above......only code was 33, then i had to disconnect my neg. batt cable cuz i was doing some work and it reset the code, so the only code was a MAP sensor code, now its gone Quote Link to comment Share on other sites More sharing options...
toastemcutlass Posted January 7, 2003 Report Share Posted January 7, 2003 havent you ever played with fire. a little bit of gas on a dip stick will just burn not "go boom" and yes oil burns but at a much higher temp than gas if you hold the lighter up and it does not start on fire right away then its not gas. The map sensor will do that if its mest up, the map sensor tells the computer how much air is going into the engine so if the sensor is faulty it may do that. not sure why the light is not on.

TGPilot Posted January 7, 2003 Report Share Posted January 7, 2003 Not to sound like a total dork...but synthetic oil does not burn. It was designed during WWII to run in piston driven aircraft. If an airplane was shot and it leaked oil it would merely smoke and never have the volitility to burn and allow the pilot to try to get away or bail if he so desired. Regular petrolium based oils burn very easy without much heat required. Sythetic oil is just that...synthetic. Webster's definition of synthetic "produced artificially by chemical means", "not genuine". Petrolium based oil is refined crude oil....just like your gasoline...flammable. Is your oil very thin?? Do you have good oil pressure when you first change your oil and then it gets low after only a couple of days?? I would put a lighter to my oil dipstick as well (not the dipstick tube). It will only tell you if you have a severe problem though. I would look to see if you lose pressure on your fuel rail first. That could be tied to other problems in your fuel system...but it would be a start... 8) Quote Link to comment Share on other sites More sharing options...
toastemcutlass Posted January 7, 2003 Report Share Posted January 7, 2003 hey I said to the dip stick. but I didn't know that about synthetic cus I don't use it, but is good to know. I know its hard to admit but does the car burn oil ( not the normal but where you see smoke). If so the chemicals in the synthetic may have acted differently to the o2 sensors. I work at the emission place by my house and a lot of cars with leaking head gaskets have that problem which causes them to fail on hydrocarbons or unburned fuel. well just a thought Quote Link to comment Share on other sites More sharing options...
TGPilot Posted January 7, 2003 Report Share Posted January 7, 2003 Good possibility...I am not a chemical scientist by any means...just did a report on synthetic oil for my Auto-Mechanics class back in '89. Now I am feeling old!!! Quote Link to comment Share on other sites More sharing options...
OldsmoBeast Posted January 7, 2003 Author Report Share Posted January 7, 2003 thanks for all the help guys. i think i'll prolly look more at my car on the weekend.....stupid schoolwork's been holding me down!
