Just a general question... What would cause a vehicles oil to smell like gas?
My mom has a Colorado and her Oil light came on today. Once home, she let the truck cool down and then checked the oil, the level is fine but it stinks like gas bad. It has just under 7,000 miles and the oil was changed just 2 months ago using Mobile 1. She made an appointment with the dealership but the earliest they can get her in is next Wednesday. They told her it was "no big deal." She's calling another dealership to get a second opinion. In the mean time I was just wondering what some of you mechanically inclined people thought.
It could be a blowby caused by bad piston rings and/or overly rich fuel mixture.

yea blow by or overly rich would be the only thing i could think of. chances are they will just look it over and end up rebuilding the motor. just a defect when mass producing a vehicle.

Ya warranty and free rental, so thats all good. She'll probably just end up trading it in when all is said and done cause she wants a Magnum.
could be a leaky injector, the left over pressure in the lines when you shut it off can leak out the injectors when the cars off and it happens the gas can go right past the rings and wash the oil off the cylider wall. As others have said blown rings could be the problem, try starting it up and take the oil filler cap off and cover it with a piece of paper, if the rings are messed up you will feel air coming out the oil filler and with the paper there you will be able to see it flutter around, dipstick tube works as well. are there any misfires or codes stored? Try what i said above if theres no blow by coming out its more the likely an injector problem, overly rich wouldn't really do it because if its so rich that gas is draining out into the oil then you would have a misfire for sure.
But if they say don't worry about it then @!#$ it, they told you its fine to drive your covered if anythign happens to it from driving to much, blow the @!#$ up and go for a new engine, thats what a warranty is for hahahah
Did you\she break in the engine? When did you switch to the synthetic? if you did it before the engine was fully borken in you might not have given the rings a chance to seat properly, thus causing the blowby everyone is diagnosing..
there is no break in on new engines
oh and since there is gonna be someone that argues over it...
new engines have NO break that you need to do, with the rings used in todays engine you start the engine run it at a high idle untill its at full operating temp then just let it sit at normal idle for a minuets and that is it, all of which is done long before you get to it. The outer surface of the rings is made with a really weak metal so they take the shape of walls almost instantly, as that wears down the real ring metal wears in as the weak section wears away, the is no break in on the engine. The break in period is more or less a break in period on the trans, and differential, and things liek that. Also synthetic has nothign to do with it, synthetic oil comes stock in alot of cars nowdays, you can't run sythetic to early.
The engine break is like a tune up, the term is still used but so outdated it doesn't even aplly anymore, a tune up is tuneing up the car, tuning how it runs, thanks to computers the car tunes itself up multiple times per second, but people still take there car in for "tune ups" all the times....
Sorry darkstar, but I completely disagree. Your rings will not be fully matched to the walls in less then a 100 miles. Now, theres not a whole lot you have to do really to break the motor in "Safely", but it won't reach full wear-in until 100-1000 miles, depending on the RPM range the motor sees....
And to the poster... it could also be a headgasket problem. Check your coolant level/color to see if it seems off... if ur coolant is low, then its like 99% that its the HG.... if its not... well it could still be either.

Maybe Im just pissed, pissed that my freinds are spineless, What else would you
call abandoment some night, when you're in a fight, and they could make things right?
Spineless. I miss some of my old friends, the ones who you could count on,
bet a huge amount on, the fact that they'd always have your back... Its like a kick in
the sack, just knowing, you've got nothing to fall back on. @!#$ this, Im done.
i agree w/ darkstars......being he is a tech and i am an ase cetified tech......there is alot of differences between the days of old and now
Ditto on the "no break-in needed".
I don't know what kind of oil it came with from the factory but it was changed at like 500 miles over to mobile 1.
They just changed the oil, we'll see what happens.

Not going to argue here, but...
Some car manufacturers will disagree with ya there man. GM requires break-ins so does Fords, Hondas, Kias, especially Mercedes' AMGs<<(For 500 miles with window sticker and all). Some require as little as 250miles of extreme easy driving to as high as 1000 miles.
Sizzy, from the looks of it that this may be the culprit of your problem: not a proper break-in was done. Have you thrown a Check Engine light as the fuel mixture (may be) to rich?

Im with Goodwrench being Im Mr. Goodwrench too...
Heres what I would do.....drain out 3 quarts and blow the @!#$ up, if a hole doesnt happen in the side of the block, then put the proper oil back in it....
My buddy had a lifter noise in his Silverado, he was just going to have new lifters put in it, but I recommended that, he blew it up, covered it under warrantly, and I got payed hella good time for putting in the new motor.
i had a crack in the intake on my ranchero, that caused gas to drip into the oil
i miss her
Sorry.....

liek I said the engine itself is not what needs to broken in, there is no break in the engine itself, on the vehicle as a whole yes
My mom doesn't drive fast at all, she's not peddle heavy in the least and she hardly does any highway driving. I doubt that truck has gone over 70. Like I said the factory oil was drained after 500 miles and it was clean.
I dunno, that just doesn't make sense.
Well thanks guys, we'll see what happens.
ASE Certified doesn't mean much. Not crackin on yall... but what the general public doesn't know is theres ASE certifications for everything... AC,drivability, electronics, auto trans, manual trans, dealer specific.... and on and on and on....
I just went to UTI, where I was taught by a peanut gallery of instructors with so many ASE certifications between them. My personal favorite instructor (Dr. Watson) is in the ASE Hall of fame twice, ASE Buick tech of the year 3 time, Chevy twice, and pontiac once... this dude is the god of all things car.... and he disagrees with you, and I believe him, sorry.
I suppose I should rephase exactly what I mean... There is not any break in that you can do to your engine(way you should treat it to make it better), but that engine is NOT broken in when you drive it off the lot. 0% chance. Maybe you should look up oil consumption numbers from the first 1000 miles compared to the 2nd 1000.... thats all I have to say on the matter.

anther UTI know it all hahah First of all certifications don't mean much of anything, I'm ASE certified, EPA certified, liek 17 audi certifications, a few more from VW... I've worked for BMW, VW, and an independant shop... does that me the god of all cars?
dude wiat till you get out in the real world, you realize how little you know form UTI and how much you have "learned" that doesn't aply to anything or just plan wrong. No instructor at UTI is a god of all cars, in truth most of them were average techs that got injured or techs that couldn't make it. Anyone with skill who gets out of working on cars gets out of the field or moves UP in posistion.
If the car is built right to begin with there shouldn't be ANY oil consumption on a new car, compression tests will raise slightly higher after a 1000 miles or so but not enough to warrant a change in driving style, wether you drive it liek a grandma or not the engine is not gonna "break in" any differently. The have cars with sollar powered sunroofs that run fans to ventalate the hot air out of cars while they sit in the sun, variable valve timing, variable valve lift, messagers in the seats, adaptive cruise control that will slow the car down on its own when it gets to close to another, suspension/shocks thats are adjusted 100+ times a second with the use of magnatism, transmisions with 2 input shift thats starts enganging a gear while its still coming out of a gear so there is never a momentary loss in power during a shift..... all this technology, why is it so far fetched that they can come up with a set of metal rings that breaks in quickly?
LOL.... First off, don't prejudge me just because I brought up the name UTI. I dominated that school without trying. 4.0 and a perfect on EVERY lab final. I would neveer ever go there again, or suggest that anyone ever does. Its designed so idiots can pass. Also, I am well aware that alot of the instructors there are complete idiots. I scored higher on the fake ASE tests then 4 of the instructors did. (they made them take the test with the class, boy they felt like idiots) Trust me, if you met this particular person, I think you would respect him. Your certifications make you the god of VW/AUDI cars in my opinion... and Dr. Watson is a god of GM cars. nuff said.

Funny, you just @!#$ agreed with me. I said that they way you drive it doesn't effect the overall outcome of the motor, but it doesn't reach its final "broken in" status for 1000 miles or so. What the @!#$ are we arguing about?

That is all. Go about your business now.
