firstsubi Posted July 21, 2011 Share Posted July 21, 2011 Was just reading about people putting two stroke oil in the gas for their car ( 1 oz per 5 gallons) and was wondering if anyone here has done it or know someone that does? And what are your thoughts on it.. Quote Link to comment Share on other sites More sharing options...

skishop69 Posted July 21, 2011 Share Posted July 21, 2011 It acts as a ring lubricant and 'prolongs' the ring and cylinder wall life. Of course, since the Subies design has the rings practically swimming in oil, it won't really accomplish anything. Quote Link to comment Share on other sites More sharing options...
firstsubi Posted July 21, 2011 Author Share Posted July 21, 2011 yea there was a 50 some page thread on another web site i was reading. They were making it sound amazing, better running car better mpg cleaner entire system from fuel tank to cylinder walls. Quote Link to comment Share on other sites More sharing options...
81EA81 Posted July 21, 2011 Share Posted July 21, 2011 I did it on an old Trail 90 with worn rings, If its not a lot of oil it shouldn't harm it Quote Link to comment Share on other sites More sharing options...
heartless Posted July 22, 2011 Share Posted July 22, 2011 actually, had someone recommend this for the lawnmowers for long term storage (over winter) supposedly keeps the fuel "fresh" longer creating fewer problems with varnishing in the small passages of the carb. I have not tried it on the mowers yet, or anything else for that matter. like i said, was recommended for the mowers - no one said anything about using it in cars to me.

Idasho Posted July 22, 2011 Share Posted July 22, 2011 Adding oil to the fuel effectively lowers the octane. So you will probably need to back the timing off a bit to avoid pinging. Quote Link to comment Share on other sites More sharing options...
Subarule Posted July 22, 2011 Share Posted July 22, 2011 How would this be better than running Marvel Mystery Oil all the time in the gas tank? MMO is inexpensive, readily available & has been in use for engines since 1923. Quote Link to comment Share on other sites More sharing options...
firstsubi Posted July 22, 2011 Author Share Posted July 22, 2011 the thread was talking about switching from using lucas gas treatment to 2 stroke marine oil. Its cheaper then the lucas and they said it works the same. Quote Link to comment Share on other sites More sharing options...
el_freddo Posted July 22, 2011 Share Posted July 22, 2011 I've heard of the older diesels doing this to bring the new diesel fuels we have over here more inline with what the engine was designed for in the first place. With all of these new electronic injected diesel engines on the market the fuel has changed to meet demand with no regard for the older style engines that still needs something that's less refined. Apparently the 2 stoke oil added in does the trick... Cheers Bennie Quote Link to comment Share on other sites More sharing options...
Ricearu Posted July 22, 2011 Share Posted July 22, 2011 rotary guys use a higher ratio. it saves the apex seals and face seals. my friend had an 84 rx-7 and he used 1oz per gallon. it smelled AND sounded like a leaf blower Quote Link to comment Share on other sites More sharing options...
Subarule Posted July 22, 2011 Share Posted July 22, 2011 the thread was talking about switching from using lucas gas treatment to 2 stroke marine oil. Its cheaper then the lucas and they said it works the same. I know it was but I'm wondering what's the difference between using 2-stroke and MMO. Do they affect different engines parts? The MMO is a gas treatment also. Sorry, did not mean to hijack the thread, just wondering if there is something better than MMO I should be using, like the marine oil.

Ginger48 Posted July 22, 2011 Share Posted July 22, 2011 Do a Google search on Marvel Mystery Oil and MSDS. It's just lubricating oil and mineral spirits (paint thinner) Quote Link to comment Share on other sites More sharing options...
bratman2 Posted July 23, 2011 Share Posted July 23, 2011 One oz. per 5 gals. is not enough to adjust timing over. Older gas had lead for a lubricant. Modern gas is fairly dry and would probably do better with a small trace of oil in it. I been using a little Mystery oil in my Brat for years. Also drop an oz. per tankful in my Suzuki Bandit. Two stroke oil might be a cheaper alternative. Seems like I remember reading something on the motorcycle forum several years back about a TC3 two stroke oil as being the best. Don't quote me as it was a long time ago and I had thought abouit trying it but never did. Quote Link to comment Share on other sites More sharing options...
coxy Posted August 10, 2011 Share Posted August 10, 2011 There is merit in the idea for some applications,though I don't believe it would apply to a Subaru. I have used it for a few years on Honda CRF 250 MX bikes where the extra lubrication extends piston and ring life and it helps greatly with keeping the Titanium valves alive longer. Honda recomend replacing the Piston every 15 hours running time,with the addition of a small amount of premix 2T oil pistons are still measuring up to spec at 50 hours using Motul 800 synthetic two stroke oil. Valve wear is greatly reduced as these run a ti nitride coating and as soon as it goes south valve clearances change hourly,this definately extends valve life.
