2 cycle oil in motor cars?

[TexasPlumber]

ok so whats the advantages using two cycle oil in gas? and what amounts? and will it help with this new crappy ethanol fuel?

 

[skyactiv]

It'll help out if you have a Mazda with a rotary engine. The "new" crappy ethanol fuel has been around a minute.

Some people are claiming benefits to using 2-cycle oil in 4-stroke fuel such as cleaning of the fuel system and combustion chamber, upper cylinder lubrication, improved fuel economy, better driveability, smoother idle, and a few others.

Most people doing this will use 1oz of 2-cycle oil in 5-7 gallons of gasoline (1:640 to 1:896 ratio).

I've known folks who did it on older cars as an upper cylinder lubricant/lead substitute.

I've never seen much value in it for that personally-it probably does about as much good as adding MMO.

2 stroke oil has detergents to keep low carbon deposits when MIXED RIGHT. Lubrication, yes it does. I poured a quart in a tank, does wonders.

too much can cause deposits.. esp in engines not designed for it.

I don't think I would do this on an emissions compliant vehicle. Long term use will likely lead to catalytic convertor issues. If you want to use an additive I'd pick the appropriate one.

Just my $0.02

i add marvel to all my small engine gas, but i keep plenty of the 2 cycle on hand. i could just as easily use that and save a trip. i think that kinda thing might be good for those little carburetors but thats just a guess

come to think of it, when I was a kid i only had one gas can. 2 cycle 40-1 went in the push mower, weed eater, and go carts. it all ran ok if i recall

How old? They were likely all 2-strokes

MMO does no good in anything. IMO, it’s snake oil.

na man they were all 3.5 hp briggs. the kind that you dont care if they smoke a little haha

im really thinking of adding a bottle to my 5 gallon gas cans that i use for the mower and generator.

Well that’s a surprise.

Well that’s a surprise.

i was just thinking it may help the gas keep a little longer or help protect the carb components from corrosion from that ethanol. i do keep alot of gas on hand in case of emergencies so prolonging the life is of interest.

Just No. You should mention the exact engine you're having problems with that you hope to solve with this cockameme idea, then given enough details, someone will know the solution to your problem.

It does not somehow cancel out the detriments of ethanol blend fuel, but again depends on the engine, the "problems" may not exist.

What I'm getting from your replies is that you didn't notice an immediate problem, but if you put oil in gas for engines that don't need it, you get carbon deposit buildup and if you put in oil that has additives not meant for 2 cycle, again extra buildup.

These kinds of things were worked out a long time ago. That's why 2 cycle oil is 2 cycle oil and why 4 cycle manufacturers don't tell you to put oil in your gas.

A properly working engine made within the ethanol gas era has no problems with it, as long as you don't let old gas sit in the fuel system long enough to foul and built up goo and varnish. Keep running fresh gas through it or drain the gas out for extended storage.

im not having problems with anything.

^ But you are. You are experiencing increased buildup rate, just haven't had to do a cleaning or repair yet due to it.

how is that? i dont add the oil to my gas unless needed. im just thinking about it. besides, this fuel would mainly be for a portable generator. they dont get ran often but i need it to run when i need it

Before you do anything else, do a BITOG forum search on "TCW3" and read. There is already a mountain of information about this topic here in the forum.

That's the function of a fuel stabilizer product specifically formulated for the purpose.
