this is awesome

 

sO THE GAS IN THE OIL IS A NON ISSUE..?

OH OK, GOOD TO KNOW CONSIDERING I TALKED TO MY FRIEND THAT BUILDS ENGINES FOR HIS OPINION. I WONT EVEN TELL YOU HIS REPLY BECAUSE ITS NO BIG DEAL TO YOU GUYS. ILL JUST TAKE HIS ADVICE AND GET IT RESOLVED.

THANKS GUYS

 

As NMX has pointed out, this whole issue of fuel dilution has been addressed elsewhere (https://www.evolutionm.net/forums/ev...l-problem.html) and all the above and more has been addressed including Papi's scepticism. I encourage all interested in this issue to visit this site for therein others are going or are waiting for test results of their oil to establish the actual %fuel dilution under Mitsu prescribed oil change cycles.

Now as far as Oil Doc being biased because he sells oil is unfair. He merely stated that 2% or higher (we have results from only two X's and both have exceeded this value) fuel in the engine oil is excessive. He has never said that Amsol oil, which he sells, should be used to correct the problem or the like. Clearly there will always be fuel in oil; it is the level or quantity that is of concern. So at this point, we should ask, what level of fuel dilution is acceptable? Do all the testing companys say 2% is too high? If the answer is yes, then we need to document the levels in our X to establish an average value (see original thread for suggested next steps).

Now to causes, which is jumping the gun for we may not have a problem here, rich A/F and rings have been suggested herein but they are just that, suggestions. In the thread alluded to above, another suggested cause was also provided, namely, injectors. Now the only NEW item raised in this thread is that from gsr0801 for he claims that one of his injectors was the cause for the fuel dilution. That said, he did not respond when queried about the source. If we have a fuel dilution problem and it is due to injectors, then this fix is a hell of a lot easier than say, rings.

To get to the bottom of this issue we need all your help; collect and have analyzed your oil (see recommendations in STI2EVO's original thread and, yes, it will cost you some but small $$) and post your results along with the mileage between oil changes. By so doing we can actually accomplish something instead of blowing a lot of hot air at an issue that may deserve attention.

Finally,I would like to suggest to the Moderator to merge this thread with that cited above so we do not go over the same ground again.

Later, Ken

Whoa, that's a loud post. I don't think anyone was trying to step on toes. It's just that car forums seem to make people a bit paranoid about their cars. Papi was just trying to bring some levity.

If your engine-building friend had good info, please share. I know I'd be appreciative.

 

Edit: MERGED!

 

Ok all, I am getting my oil changed in a couple days, and am sending off my results. I have been waiting till I had 2k miles on the current change, because I didn't want to have too little miles to give accurate results, but also didn't want to go to the full 3k if it's as bad as I am worried it is. When the results are in, we can multiply the number by 1.5 to give the estimated percentage of what the fuel dilution at 3k miles would've been. Will have results soon...

 

That's all im trying to do, there might be a problem. But people blow things out of proportion. Next thing you know someone is going jump of a bridge because their 35k car has fuel dilution problems.
To tell you the truth Sti2EvoX if you noticed i didn't post here for a while, thinking that the admins would merge the thread but i guess not.

 

Same here, oil smells like gasoline. And my oil was changed after the 2nd dealer flash.

 

Papi, I just brought this to the mod's attention, so this should get merged today hopefully.

 

This thread has been merged with a more recent one about the same topic, in case any of you guys notice a shift in the conversation. Thanks.

Ok, now that we're merged, let's get back on topic. I would ask anyone who has not voted in the poll already to please vote, because the more votes we have confirming this issue, the stronger case it will make with mitsu. Again, do NOT vote in the poll if you are tuned, as the issue here is caused by the overly rich air fuel ratios of the stock tune. Thanks all.

 

Are we sure about that? Or am I misunderstanding you? I thought there were a few theories about the dilution (AFR, injectors, rings, more?). It's always possible I'm just confused

I think it would be really nice to see results for tuned cars. Maybe people can post but not necessarily vote in the poll. If we see cars with tunes still exhibiting fuel dilution, then we can't blame the rich tune any more can we? On the other hand, if we get proof that a better/leaner tune fixes this, it will be good news for all.

 

If a car has been tuned, it will have no effect in a case with Mits. That is why he is asking for Non-Tuned

 

So where is this thread going? I'm wondering if it's even worth the hassle of all of this.. I have put less than 1k miles since my last oil change and my oil already smells of gas. Will Mitsu actually do anything or should we go ahead and start taking precautionary measures on our own? I seriously want an accessport to go ahead and clear up a lot of the issues that Mitsubishi should have fixed before the release of the car!!

For what it's worth, I've never had an issue with this, even when I was running on track un-tuned with a few bolt-ons.

Now that I have a tune, when I changed my oil last week I took a wiff of the oil and didnt smell any gas...just smelled like clean oil. Not much help, just showing that not everyone is affected by this.
