About 2 Stroke oils

The best local oil is on clearance due to the EPA.
Mobil 1 2t for $1.00 a quart.

That's the stuff I use. (Mobil 1 MX2T or Racing 2T) How is the EPA responsible for Mobil discontinuing the oil? There seems to be plenty of other "high performance" synthetic two stroke oils out there, so why did they target Mobil 1?

I am pretty well stocked with the Mobil 1, so I won't need any for a couple of years. Wish I could find someone selling the stuff on clearance for a buck! (I paid 6-7 bucks a quart)
 
tc-w3 ooutboard oil is meant to run in a much cooler-running engine (all outboards are water-cooled) so, the oil isn't as thick or lubricating as air-cooled engine oil. And if you put that oil in a very hot-running ht engine at the same mixture, and run it for long periods of time, you might have an engine failure.


EXACTLY. You'll lots of piston scuffing and eventual loss of power and if you are lucky, eventual engine failure if you don't realize you have lost lots of power and your engine isn't running as reliably.
 
Pablo,
I noticed you fouled a plug (as posted in BITOG). Have you considered lowering your castor content? 50/50 is much too much castor; all you need a touch 10-20% to do its magic. I haven't fouled a plug yet but suspect i will now that I'm running 100% castor. I don't mind fouled plugs, a minor inconvenience.

Not so much castor which was running fine - but stale premix with castor. I knew I was chancing it. My tank was nearly dry, so I dumped in some month old stuff. It immediately ran like khrap. Then it fouled the plug. Moral of the story: Ethanol fuel is bad enough, but mixed with castor oil and aged a month is no good. So now I'm back to 100% Dominator mixed fresh, at 30:1. Engine is running great.

Thanks for your reply.
It says on the back of the container suitable for watercooled and air cooled.
 
Thanks everyone for your replies. I mainly wanted to educate myself to see if there is any differance and what it is. If I'm not 100% sure I'll just take it back. Just that it was a synthetic oil and very cheap. I might just keep it for my lawn mower and whipper snipper.
Anyway here is what Valvoline said.
Hi Gilbert,
Was your bicycle store purchased, or home built?
If store purchased, it should have a handbook, describing the oil to use.
If home built, I would presume that you have used a garden type motor, ie whipper snipper etc.
The outboard two stroke can be used in garden design motors, as long as using std unleaded fuel, and maintaining a 25:1 ratio.
regards,
Michael
 
has anyone used lucas semi-senthetic 2 stroke oil...
i am tempted to use this oil, becuase this is the only good 2 stroke oil availabe at local stores??
 
HI,

FWIW I used to use the 2 stroke oil they sell at Lowes called Pro Mix for all my 2 stroke equipment and HT engines.....then I decided to try the stuff they sell at Wal Mart in the blue gallon Jugs....like yours it says for Outboard motors but this one also mentions and air cooled engines....It seems "thinner" than the Lowes oil and calls for 2 more ounces to be added per gallon of gasoline than the Lowes oil....I haven't had any problems so far BUT I have been putting in just a little more oil "just in case"....I may try running less oil in the future but the oil was so much cheaper than what I was using I figure an extra ounce or 2 per gallon is not all that much...Doesn't seem to smoke or run any hotter than usual....

Andrew
