Idiot gas mix

[gasman24]

I was getting my boat ready! You know all this **** we do that we really don't need to do, but we do cuz we are fired up about going. I have a Merc 25Jet 2 stroke 98! This motor has extremely low hours and for two years starts like a champ and throws my little 1448 Modified around great. I made a pretty rich mix (a little heavy on the oil) I always do. But this time I saw I had a jug of Marvels Mystery oil And though why not. I added about 3 onces of mystery oil to 4 gallons of two stroke marine mix for my outboard. After I ran the boat for a little and used the fuel already in the lines I noticed the motor running rough. The more it ran the worse it got. Then I actually had to run the motor will the full choke to get it to run right and get me back in. Has this happened before to any body? Is 3 ounces to much for this mix. Do you recommend using Marvels in a two Stroke? When I got home I pulled the plugs they were a little hot looking but not at all fowled. The fuel filter had a bunch of debree in it, but nothing I could see causing a blockage. I think the mix was the problem. I have always heard to much just smokes more, but this didn't smoke to much just did not like the new gas. Looking for help

Hi,

I would not use it in my engines. It is a high detergent oil that may have phosphorous in to do the cleaning. If it does it will wear your bearings and piston skirts out. This is "not a fact", just an assumption of mine. I have seen oils turn to a gel like material when mixed too. This may account for your rough running or it was just the freak timming of the whole thing.

Re: Idiot gas mix

agreed, do not continue to use this, and i would almost pul the exaust cover off and check out your pistons and maybe even do a compression test hopefully you didnt do any damage :S

Re: Idiot gas mix

Additional oil actually LEANS the fuel mixture, raising combustion temps.

I wouldn't risk an engine on a 'What If?' idea.

Ya think there was any reasoning for OEM's dictating the use of TCW-3 rated oil?

Save the Marvel Oil to lube up your air tools, it works great.

Re: Idiot gas mix

Thank you for all the replies I guess it is a unanimous decision Marvels is no good for 2 cycle engines. I am going to make a new mix using the correct amount and go from there. The motor ran fine with me manually working the choke so I really don't think it is an engine problem. More of a fuel or carb issue now. Just so I have it right, you guys mix 50-1 perfectly and thats that. SO many guys have told me go heavy the worst thing that can happen is smoke. I geuss they where blowing smoke!

Re: Idiot gas mix

Just to update. Threw the old gas in my truck and re mixed a new 6 gallons exactly 50-1 . Added the right amount of stabl and it fired right up and ran great. This motor is the real deal just doesn't like Marvels Mystery. Lessoned learned thanks
