I reckon that your ignition is more to blame for your problems than premix. Come back and let us know once you upgraded the coils and and wires.

 

Premix does not cause MAF issues or oil overflow...those are problems with overfilling your oil and oil getting sucked into your intake as a result.

Oil and fuel systems are totally separate.

 

Yes, I may have overfilled the oil. I doubted myself and pointed the blame to the premix since it coincidentally occurs at the same time the first few fill ups and premixes I did altogether.

 

On my 'to do list' this weekend It's been more than 37,000 miles since the coils have been checked.

 

Gas is the major contributor to carbon buildup, oil actually keeps the internals a bit cleaner if it burns right. At least where it matters

Don't focus too much on idemitsu or this or that brand, read a couple of motocross forums and see what leaves their engines clean.
I had a bad experience, like many others, with castrol's TTS line. It cocked my 2stroke engine up in less than 20hrs of use. Other lubricants left it way cleaner

 

So lots of talk on premix here (i use idemitsu btw), but very little regarding the actual benefits of adding FP+ to any premix. What is the general consensus on this stuff? Pretty damn expensive stuff too heh.

edit: Meh figured id skip the bickering in this thread and ordered a few bottles of saber pro w/ a bottle of fp+ to try for myself

 

You still not understanding.

Exactly.

I suggest reading this entire thread all over again.

I read up on that stuff but I don't really see the point of using it. A good 2 stroke will burn and clean well. The FP+'s working ingredients would be rendered useless in the presence of the 2 stroke I would think. I have read that newer gas stations use plastic tanks and filters which supposedly cleans up the gas pretty well. So considering fuel is the major cause of carbon build up, I try and only use the new Shell station by my house. I have also read that there really is no better fuel system cleaner than Techron.

 

Thanks for the tips. I use the shell station close to my place and only use their V-Power gas (when i visit home I am forced to use Mobil 93). Since I ordered it I guess i will just drop an ounce per tank for good measure, we will see what happens i guess. Looks like some people stated that their exhaust is less sooty on their tail pipes so if i see any difference i might continue using it. Doesn't hurt i guess.

 

I have only heard good things about it from guys who use it on Piston motors but they are not premixing their gas with anything else so it's not a fair comparison. I would get a glass container and mix gas, Idemitsu, and FP+ and see how it all mixes together.

 

^^ Yea i will give it a shot. I will actually be using it with the amsoil but either way, probably be a good idea to test with my own eyes before blindly dumping it all in and hoping it mixes well :-p

 

I just feel that there is no point in mixing with funny/unknown stuff. Idemitsu works fine, I will stick with that only.

 

I stopped using FP+ after two users I know needed new engines. In and of itself that doesn't really prove anything because so many people have needed new engines, maybe as high as 25%. It sounds good in theory, ie, the whole idea of converting carbon to a graphite lubricant, but there's no real long-term evidence proving it works any better than 2-stroke and doesn't cause any potential harm. I'd rather just use clean 2-stroke in a Sohn adapter and add it as premix as well.

 

I use FP+ periodically. I go for a month with premix, then I do one tankful with 3oz of FP+ alone. I figure a cleaner will detract from the premix and premix may make the cleaner less effective. Hopefully I am guessing intelligently!

I will say I soaked a few different plug in straight cleaners for 24 hours and none of them otook anything off the plugs. I realize cumbustion adds a different dynamic, but I had them in straight cleaner. My cumbustion chamber only gets a small amount of cleaner spread over 4-5 days. I am not sold on cleaners - but do run top tier fuel in my wife's car and cleaners periodically in both.

The price of FP+ is actually low compared to Amsoil Performance Improver or Techron (the products I used before. And since I have the FP+ at home, I use it more regularly.

New question. I bought my car used and it had been decarboned 3 times in the 20K the PO had it (each time due to flooding). Do you think it would be good to do periodic heavy cleanings? I am at 35k now with new coils and wires. Plugs have 5k on them adn the car is running good, but only 183 hp.

 

I just ordered a bottle of FP Plus and a bottle of their LC20 for the oil. If you read up on BITOG, a website dedicated to automotive oils and additives, the products have really good results backed by oil analysis. It should be delivered next week and I'll keep you guys up to date on how it works on my 06 RX-8.

 

You cannot compare what works in a piston engine to a rotary (for the most part anyway). What ever you introduce in to the combustion cycle is being mixed with dirty engine oil (unless you run a SOHN) so...............

 

Well, I'm on page 71 right now... So it could be in the last 50 pages, but I am wondering something.

Has anybody done a used oil analysis before and after? When I thought about it, it sounded like a really good idea, but then when I really let it roll around in my head, it might not be as sound as I originally thought. Since all the oil in the combustion chamber is burned, premix or not probably wouldn't show up in a UOA.

What do you guys think? Would it even be a valid test to do? I imagine if you could keep as much the same between two oil changes, it would be an interesting thing to try either way...

 

Two separate systems. If the two are mixing at high levels then you have bigger problems than needing premix.

 

Yeah, that's what I was thinking. It seemed like a good idea at first (I was thinking more of a piston engine when the idea popped in my head), but after a second I figured it wouldn't matter.

Still, I might give it a try some day....

 

Noted on both accounts

 

Not sure if this will help anyone, or if there was any point in doing this, but I just wanted to see for myself exactly what it all looks like and how it all pours out:

This pic may explain a few things ....

Good work .

 

Looks bad, but explain what you are thinking?

With the Amsoil being darker, is it just hiding the same effect?

I decided a while back not to mix cleaner and lube. I use cleaner once in a while with no premix for that tank.

 

Yea sorry about the amsoil pic ...if anyone has a better idea for that one let me know...just too dark

 

In person does the Amsoil have the same "crackled" appearance?

 

The flash on with a piece of white paper behind might reflect more light through the amsoil one.
