2 cycle oil? Synthetic or non synthetic?

I want to try premixing along with the OMP and I want to see if there is any benefits to doing so but when I was in advanced auto the other day I noticed that there was 2 cycle oil as a partial synthetic and full synthetic. I understand there is a taboo for running synthetic in your rotary because it gets burned off. So what about 2 cycle oil? Is it in the same boat or is it ok to use in the gas?

Or is there a non synthetic 2 cycle oil to be used that can be acquired fairly easily?

Mixed feeling on the subject but in general use what ever is readily available and reasonably priced it all works but why use synthetic . Don't over do it or you will notice it being a tad lazy . There are many topics on this a search will most likely turn up more info than can be digested

There are probably hundreds of threads on this subject. Infact I replied to one not long ago. Do not premix with OMP thats just overkill. It doesnt matter synthetic or not for premix just good quality stuff.

Castrol Snowmobile 2 stroke stuff works good.
Petitt and Idemitsu are probably the best premixes available.

Or I would recommend Amsoil anything. Amsoil defenitely has to be one of the highest quality oils around and they have all those good additives like Zinc and Phosphorus.

Don't give out bad advice. It isn't overkill, its a great way to further assist in *properly* lubricating the engine.

I would say its a matter of opinion and preferance.

If you're not driving hard on the car alot then I would say its really not that neeeded, and if you do use pre mix and use the omp 1 oz per gallon would definitely be too much considering that's what's used when you have the omp deleted.

I'd say .5 per gallon or .25 per gallon.

If you can get your hands on in straight B100 (biodiesel) is, IMHO, the best 2 stroke oil ever. It even mixes with alcohol.

As to amounts, I'd say if you're keeping the OMP stick to wthdidusay82's recommendation, it's been covered a lot.

If you're ditching the OMP, I've been fine on the B100 with the standard recommended 1oz per gallon.

There are no documented benefits to using premix with the OMP. If you have a race car, then delete the OMP and run exclusively on premix.

Early blends of synthetic oil did not burn properly in rotary engines. Most oil made after the mid-80s will work now, although some burn a little better than others.

My convertible has been running for over 200,000 miles and 25 years with just the OMP. Therefore, I would contend that the engine is 'properly' lubricated as-is, and additional premixing is a complete waste of time and money. Not all race mods are practical for street cars. Don't give out bad advice.

maybe i'm missing something.. B100 is a fuel thinner and not a 2 stroke additive.

Oh, I'm *sure*..

While the factory oil injection system is adequate, it is not perfect. You are basically saying "Hey ! I've been alive and well without ever taking a multi-vitamin, I get more than enough from food !" Yes, you get by just fine, but your body could run better.


So don't get snappy.

Redline 2 stroke oil has always been my top pick. Read up on it if you want.

Using your own analogy, what Aviator said was, "Hey, I've lived for 150 years without taking a vitamin" and you're response is, "Meh, could be better".

So, how much "better" than 200k + miles on the OMP would be enough?

how many licks does it take to get to the center of a tootsie pop? the world may never know!

that was in comparison of premix versus the factory OMP. in most cases either/or work just fine.

the main issue with the OMP is you're injecting carbon laden oil into the engine as a lubricant, if you change your oil often and keep it clean it seems to work as well as premixing does. if you don't, i notice it adds additional wear to the center of the housing.

I guess the question now would be how big of a window you have before the oil is beyond worth using and when should it ideally be changed and when are you beyond that window.

3-5k?

5-7k?

4-6k?

x to y ?

etc.

depends, motor to motor. tolerances and tuning cause more or less carbon to deposit in the oil.

Red Line Synthetic Oil - Two-Stroke Oils
You don't need to get fancy on 2 stroke. Any TCW3 will suffice.
Even Walmart brand...yes it is TCW3.
I've used all brands for years (TCW3) and my housings showed no wear.

OMP is fine...just change your oil. I've broken down an FD motor using OMP all it's life 90,000 and housings were like new (changed oil every 5months).

People who drive cars and don't change oil should be shot or forced to drive a Yugo.

Oil is cheap.
It shouldn't be thought too hard whether you should or should not.
I change mine every 5 months no matter what.

In my old NA I tried to change every 3000 miles which was probably sooner than it really needed, later on the mileage between oil changes got higher when I was broke.

I've gone as high as 8000 miles on a piston engine on conventional Dino oil, maybe around 5-7k Max in my old NA rx7.

I always use castrol gtx

Yes, multi-vitamins are a scam, and you are much better off eating balanced meals.

I run Motul synthetic 2 stroke oil for my premix. No ill effects, no smoke and extra peace of mind.

Actually sugar, multi-vitamins are only a scam to those that are ignorant to the world of pharmacueticals and general medicine. Try some pharmacy school and get your doctorate like my mother did, then come back here and tell me I'm wrong. Jackass.
