Hey everyone


Just wanted to ask a quick question, ive had this issue for a few days now and i'll start off now with what's going on

so the other day i had NO GAS and my dumb self thought it would be a good idea to put some pre mixed gas (oil and gas, 50:1 ratio to be exact) into my tank. I ride dirtbikes and snowmobiles so i had a bit left over.
I decided to put like 25L in of it in my tank, my gas gauge went from 1 quarter to 3. started the car, and it drove just as normal as it should, but anytime i went WOT with preformnce shift it would shudder and lag and struggle to ring out almost like it was WAY to rich and choking on the oil, I thought maybe it's mis firing but no check engine light came on and the car ran great aside from the WOT lag. coolant temps where good and no power loss, (I got pretty good gas millage too) well a few days later i got it down to half and went to the station and filled it up with my normal gas (91 non ethanol) and the shudder was still there but not as bad. I also thought maybe the cat was getting clogged from all the oil but it started up so quick (and still does) and it has no power loss.

Now part of me thinks i'm getting KR and it's computer is retarding it but would it be so bad that it would cause the car to struggle like that? (this has never happened before) the temp stays at 80C while driving and WOT and has never seen anywhere close to 100C


I know i know i should not have put that in and i realize that now.... What could this be? I just went out and did some small pulls and it was struggling to get going, before when it had a full tank of it it was like cutting out and really bad at WOT.


brand new plugs so it can't be a gap issue?

what do you guys think?
 


i'll be checking it when i remove it as i'm putting a new dp in, and the fuel filter? You don't think the oil would pass right by it?
 


I've put transmission fluid in the gas tank before to clean the fuel system, didn't harm the filter lol.

By the time the fuel mixed with the gas in the tank already and the added fuel it going to be like 70:1 and have should have basically zero effect on how the vehicle runs. Hell I've ran a car with diesel mixed in the tank after someone didn't know what they were doing and it still ran fine.
 
I wish it's was a troll, like I said before could this be KR? It's never been this bad.

I think there is still some oil left in it. It's getting better, I'm thinking by the time I fill it up again it will be gone but I'm not 100% sure
 
I also forgot to mention, this two stroke oil likes to separate at cold temperatures. When I took the car out in the morning and warmed it up it didn't lag like it does when I'm driving it six hours later, maybe I'm crazy i dont know.
 
Oil significantly reduces octane level. But I'm still convinced that no one in their right mind would see that their car is running like crap and then continue beating on it.
