Alright, a few buddies of mine have been arguing over this, and I've been dragged into it...

So 'GXLguy', he has the stock OMP hooked up, and he add's about 8 ounces of Marvel Mystery Oil to his tank every time he fills up from empty. 'Streetport-dude' keeps telling me how it's giving 'GXLs' engine too much oil, decreasing 'GXLs' hp and what not.

So 'GXLguy' is saying it's good and all because his OMP's worn with it's 175K miles and it's more like a safety precaution. And the MMO's breaking down carbon.

And I searched a little about this, but I can't find much; 'Streetport-dude' rev's to around 2K then shuts the engine off, because he say's its good. And 'GXLguy' say's it's making it more prone to flooding. Help here too?

Any idea's guys? Thank's in advance.

**and if your gonna post reply's and be an *******, just don't post please **

 

revving before shut off is about as stupid as it gets, and i put about 8 oz of premix per every fill up.

 

and is your stock OMP still intact and working or is it removed?

 

removed, blocked off, gone

 

any other takers? and 'GXLguys' saying it give him better fuel economy and cleans the fuel injectors as well... fact or crap?

 

Dont use mmo, use tcw3 2 stroke oil.

Also, revving the engine to 3k before shutting it off helps prevent flooding if you have very low compression or leaking injectors.

 

It wont do anything to fuel economy. its combustable oil... how does that improve gas milage. it will make your cat burn out faster, lowering fuel economy.

 

because.... ?

 

i don't know if its any better than two stroke oil but he's most likey not hurting anything by adding the oil.

Revving the engine to prevent flooding isn't doing anything about the reason why the car floods. maybe he has leaky injectors and a bad hot start assist thing or something that can be fixed.

I'd say GXLguy is winning so far.

 

Because TCW3 is designed for this purpose.

Read up about premixing on the forum.

 

I've wondered this myself. I have the stock mechanical OMP on my T2 and I'm thinking of throwing in some premix just for extra protection, and I wonder what brand and how much it should be.

 

as for the revivng thing, it may help with flooding (i dont know, no issue there) but i do know that revving your car up heats up major motor components, then suddenly starves them of oil when you cut the power off.

 

The premixing is fully legit. While the S4 Oil Metering Pump is bulletproof in design, the O-rings that keep it all sealed up are plain-jane and fail over time like any other gasket on any other car. It's just how it works. So while the pump may be funcitioning properly, it's leaking a fair bit of oil out all over the motor and ground and not going into your engine. Premixing is a safety net of sorts against such a condition, as it helps to keep good lubrication up. Also, MMO breaks down carbon and cleans out your fuel system quite well in my personal experience with the stuff.

As for revving up the motor and immediately killing the ignition, here's my take on that, be it correct or not.

This is a fuel injected motor. When you prod the throttle, the ECU tells the injectors to spit more fuel into the motor (Air is involved, obviously) to increase power through revolutions per minute. So if you stab the gas, more fuel is injected and the motor begins to rev...but cutting the ignition kills the ECU controlling that fuel and kills the spark that's supposed to be burning that extra fuel.
Ergo, you've just injected a ton of fuel into the motor and then only burned some of it off, but leave an excess because you killed the spark.

Furthermore, revving before shut down on a low compression motor, I'm still against that because it makes little sense to me. Someone correct me on that if I'm wrong, by all means.

 

so GXLguy's came forward...

 

it doesnt starve it of oil, it's still spinning the oil pump.

For the premix oil, use anything labelled TCW3. For people who still have a functioning OMP, run 200:1, which is approximately .5ounces per gallon.

For those with no OMP its reccomended to do 100:1.

Don't worry if you dont get the EXACT amount, youll be ok.

 

The comment about MMO versus 2-stroke...

If you've still got your OMP, I'd premix the MMO...if you don't have an OMP anymore, or yours is NOT functioning, MMO is perfectly alright. I know a few people that strictly premixed with MMO on higher horsepower motors with no OMP and were fine. However, MMO was NOT intended for premixing, but it does a cracking job of it anyway.

Amazing ****.

 

My engine flooded like crazy on my 1st 2nd gen. I revved it to 3k before shutting it off and it would start up everytime after that.

 

of course you'd prefer MMO; you're GXLguy ************
and dont start post raping...

 

Wrong. Read my post again, then come back and see if you'd post that again having known better.

 

what??

 

GXL man should test his OMP to see if it IS failing or still in good shape and rebuild if it's needed. Instructions are in the FSM. If both are working then he's probably fouling up his plugs (could be making him lose power and lowering MPG).

Now does he rev to 2K and shuts it off at 2K? Or does he let the rpms die down and turn it off as the rpms decrease? Either way I don't see why it would be better than turning it off normally. My first guess is that the injectors are leaky. Maybe he turns it off to kill the fuel pump as the injectors lose the fuel during deceleration.

Either way, rather than talking about it they should start diagnosing and fixing.

 

ok then 'GXLguy'...

He rev's to 2K or a little over, and kills it. So the rpm's die down with the engine off.

 

He revs it up and shuts it off as he's revving. Now, if he was revving it and letting it fall back down to idle speed and THEN shutting it off, it wouldn't make a bit of difference except that he just wasted some gas for no reason at all.

The guy in question "Streetport guy"... I met him. He strikes me as the guy who has a great car with a done up motor that he knows absolutely nothing about. And it's true, I'm sorry to say.

As for my fouling up plugs and decreasing economy..
Plugs seem to be alright last time I pulled them out. And my fuel economy has averaged slightly higher with no significant change in my driving style, as un-scientific as the whole thing may be.

All in all, I've no idea why Bretticans started this whole thread to begin with.
Streetport guy has been calling him constantly and always is talking about me and asking Brett if he's talked to me because he KNOWS he is wrong about several things that he in all his newbie-ness is doing that I very gently corrected him on. We've all been there, *I've* been there with a lot of what he's doing wrong.

His driving style is apalling. He has absolutely no idea what the **** he's doing and he's all about drifting. He thinks he's drifting when he's not, and his terminology is VERY Fast and the Furious.

So, to sum it up and to end this thread...

Bretticans wanted everyone's opinion on my premixing, and he's really not gotten anywhere. I've told him all that you have posted collectively and he just didn't take my word for it. I don't blame him for wanting more opinions...that's actually a good thing.
Streetport guy needs to get over himself and face the fact that I *do* know more than him, and that I'm not trying to offend him when I gently correct his errors. I even told him that when I met him, and he said it's all good.

So the fact that this thread even exists is comical to me.

/thread

 

alright guys, thanks for the opinions. I just dont want this to start offending 'streeport-dude' and starting anything, so I'm outta this. </thread>!

 

You're all asses.
