Hey, im looking into getting a fd in the coming weeks and previously i thought i had always heard that your supposed to check oil levels every 3 fill-ups or so to top it off, but recently i have been seeing people saying you should add 2 stroke oil in when you fill to help with apex seals and such? Anyone know anything about this?

 

Welcome to the forum. Please read up, you'll find this covered EXTENSIVELY; almost every other thread is a discussion on this. The action is called "premixing", just like you would 2-stroke lawn equipment. If you have a stock car with a working OMP, don't bother. If you abuse the car and are making more power than stock, it would be worth considering premixing full-time. Just don't be one of these half-in-half-out people. There is no real benefit to using premix and the OMP in conjunction.

 

as daniel said, this topic has been beat to death in every aspect.... ratios, brands, frequency, with or without omp, ect..... all the information you could need is here on the forum

 

Just take BEANO...(there'll be no gas!).

Sorry man..had to answer like that..heh,heh...Like danglin a carrot!

Seriously though,Pre-mixing is an extensively covered topic..like oil choice.
A perfectly good stock set up doesn't require it.A stripped down version of the car may or does require a secondary way of internal lubrication.It depends on IF the engine now has no way to get lubricated internally.

If you are "hearing" about Premixing then you may be Listening to a lot of Bullshit.
If you READ about it,then you can establish what it IS and IF you actually require it.
For that..I'd be taking some time to look into it and see for yourself IF it is what you need or what you do not need to bother with.
Ideally it is a great protection factor against internal failure..but then again it can be just a added cost that you do not need to incur.

 

Thank you all for the replies, I'll look into it more now, I'm new to rotors and harden heard about it until today and was unsure if it was a "thing", I'll look into the other pages you guys talked about now, if I end up getting a car that will require some work above, above-and-beyond hahaha

I plan on doing it for a fail safe but to each his own.

 

^Fail-safe for what?

 

Fail safe against non-clogged fuel filters perhaps.

 

Anyone know if theres a way to improve the oil metering pump to inject more oil? Or to inject twostroke oil so its not using potentially dirty engine oil? The price of gas here in bc is pretty high and adding twostroke oil on top of that makes this car pretty expensive

 

You've got to pay to play. Premise is worth that added Insurance to me

 

Yeah i hear you, would just be nice if there was another way. Any specific type of two stroke oil? And do you know if it affects the fuel filter? Im doing a rebuild right now and would appreciate it if this engine lasted a while, so im doing all the engine safety / detonation prevention i can find

 

theres an adapter out there that makes it so the omp pulls oil from an external reservoir instead of the oil pan. no idea who makes it or where to get it but i know it exists... and now you do too.

 

I'm not sure where you're going with this. If premixing 2 cycle oil makes the car expensive, why are you asking about a way to inject it?

Anyway, I'm not certain on the FC's if their OMP can be modified. On the FD, as I understand it, the OMP is controlled by the ECU. Bigger brains than mine could probably increase it's output but it's also probably not worth the trouble.

You can add a RA adaptor which will inject 2 cycle oil from a reservoir you will have to install and plumb...and keep full.
Oil Metering Pump Adapters

 

I keep it simple and stupid. Remove gas cap, add fuel and then add two stroke oil.

 

^Apparently you're not keeping it simple enough. Add 2 cycle and then add fuel.

 

Educate me what am I doing wrong.

 

He's getting at you should pour the oil in first for a better mix.

 

Yes you are correct to be more specific I add 5 ounces of oil for every 10 gallons of fuel. Oil first gas second.

 

Even pouring it in first doesn't make a very good mix.

I've been premixing my FC for 11 years. For no other reason than my custom intake manifold made using the metering oil pump a bit of a pain in the butt so I took the easy way out.

And I'm betting there aren't a lot of people who have been premixing for as long, on the same setup, and been willing to make observations.

At some point I'll be realising a big writeup on why premix works, and why it sucks, and stuff that will bite you in the butt if you premix under certain driving conditions.

My opinion has not changed in the, meh 18 or so years I've been playing rotary: Unless you have a reason to premix, then DON'T. Leave the working metering oil pump system alone.

Unless you have built a 500HP monster, or are at the track, don't premix.

 

Like non-synthetic vs. synthetic, what's the best hard seals, what's the best tire, what's the beer, and what playmate had the better ***... it will always be a subject for debate.

 

Yes. For sure and this boys and girls is bow threads are born. Lol
