Well About a few days ago, I thought I would give it a shot. Figured what the hell lots of people have been using it, i'll give it a try. Went to Walmart and got a can of yellow penzoil 2 stroke oil. I filled the gas tank with 92 half way and then added about 4 ounces into the tank and then filled the rest of the tank up, as to get a good mixture. I then let it sit for a few days. After the few days, upon start up as expected a lot of black smoke came tumbling out the exhaust.

Took it for a about 20 miles or so, mostly highway driving and then a little bit of city driving. Well the car was okay on the highway. In the city it ended up running like crap, it couldn't even hold idle, trying to die off. I had to hold the pedal in just to keep it alive. And when I tried starting it up again it seemed to be more of a hassle, almost flood like similarities.

Now before this, the car would idle perfectly a little under a grand, and vacuum was about 12 inches, and drove fine on the highway. The 2 stroke engine oil was the only change since.

What do you guys think, normal and I need to give it time? Or my car just flat out don't like it?

 

If that 2 stroke oil is castor, it will separate in cold weather. When I was racing 2 strokes, I usually resorted to a 50/50 mix of Redline (synthetic) and Blendzall (castor) to keep the oil mixed in with the gas.

I fouled my plugs several times with Amsoil racing synthetic pre-mix....had to push start the car....not good

before that I ran the car for several years pre-mixing "Quicksilver" bean oil intended for outboard 2 stroke engines and never had a problem....just alot of deposits and dropping vacuum....cleaned up with MMO

I've since given up on pre-mix entirely....hope my OMP doesn't take a dump

 

I use the pettit Protek-R every third tank or so. I don't notice any difference in smoke out the tail pipe when I use Protek and without. I don't like the 2 stroke oil.

 

I premix my car only on race days; for daily driving I don't.

That said I put 4oz of Penzoil synthetic 2 stroke oil in a full tank of fuel on race weekends and have absolutely zero problems. No smoke, no sputter, no plug fouling, no nothing. You can't even tell it's in there.

 

why would you pre-mix two stroke with a functional OMP???

WHY!!!

*edit* directed towards daily drivers

The thought behind it is that the OMP doesn't provide enough lubrication for racing/hard driving applications.

Pettit recommends it and they've been racing FD's for years. I trust them.

I, like Damon, only premix at the track.

 

Uh oh....here we go again

 

ive been mixing 1oz to 1 gallon of fuel....no smoke at all.....runs and idles fine....

I have no OMP

 

DAYEM!! 18oz. on a fill up?? or you don't ever fill up?

isn't the ratio something like 100:1 (fuel:oil)

 

i was told 1oz to 1 gallon....its only driven on the weekends...so I only do like 10ozs

is this wrong????

 

Thanks for the info guys, well I'm guessing it's another one of those issues, where the fd rotary is its own individual and reacts differently from its brethren fd. The black smoke only lasted a couple of seconds so I didn't take it seriously. I'm not trying to dog the process, just that my experience thus far hasn't been swell. I mean I could be wrong and maybe the idle is something else, but I haven't changed anything since premixing, so that is my only conclusion. Perhaps I fouled the plugs doing this, and only one rotors kickn' but if that was the case I doubt I would have been able to highway/freeway drive.

 

Yea, or it is the Pennzoil.

No problems with Protek-R, or Royal Purple TCW III synthetic 2 stroke. I run 4-8 oz./tank.

 

Well I actually can't wait to run it out of the system now. I'll definetly have to try something else and fix it till its broken, or just leave it alone.

 

Since that's exactly the same setup as I, did you notice any change in the vacuum? I'm curious to know what's the reasoning behind just on race weekends?

 

 

maybe you should dump a bottle of MMO in the next time you fill up. . . like when youre at half a tank or so.

Because we have these things in our engines called apex seals. They suck, go out and lead to fragged turbos. Extra lubrication for them should reduce wear and help them last longer. This is considered a good thing by most people.

 

Exactly, same reason alot of outboard 2 cycle motor owners pre-mix they dont trust the OMP, especially if its an older model.

 

I notice no difference whatsover in vacuum or any other observed performance.

Just a little insurance. On race weekends the engine is constantly singing at high rpm so I add a little premix to the fuel in order to make me feel good. My engine is stock except for a downpipe and catback.

 

 

Yay...learned something new!

 

I premix also and never had issues with premixing any kind of oil, I used 10W30, 2 stroke and many other kinds of oil, didn't change my idle, fouled my plugs nor felt any difference, sometimes I would put more that I should and the car would smoke even when warm and didn't fell no difference.

How many miles on your engine? How many miles on your plugs? Do you regularly run fuel injector cleaners? I have over 80k on my engine and I have premixed with various types of 2-cycle oils and have had no problems at all.

 

Well in order to give you the miles you'll first need to put a diaper on otherwise you'd be liable to **** your pants. lol
