Combining moly & teflon...

[gotek]

I previously owned 2 different '83 Datsun 280ZX cars with manual transmissions...pretty much identical.

Both cars got around 24 MPG overall (+ or - 1 MPG) on a consistant basis.

With the second Z, I got around an 8-10% increase in mpg by using a combination of teflon, molybdenum disufide, & fuel line magnets in the engine & manual trans/diff....an increase of at least 2 mpg.

The car was stock as far as intake/exhaust/engine timing etc.

I was using regular dino engine oil & gear oil...but with the added moly in the trans/diff. This product was called Gear Moly and WAS sold by JCWhitney (Pacific Lubricants)

In the engine I alternated between adding Engine Moly (same source) and a teflon product at each 3K oil change.

This engine did use some oil...around 2500 miles per quart.

As far as the fuel line magnets (Radio Shack)...well who knows.

I previously posted this on a list and got the usual poo-poo...but these are the facts.


Questions:

Is there a source for a moly additive that isn't too expensive...can't find any near the previous price.

Can I use powdered moly mixed in with gear oil? This can be bought for a reasonable price.

Is there an additive (Tuffoil?) that combines moly & teflon?

I wouldnt touch teflon with a 10 foot pole, Schaeffers makes a nice moly additive.

Isn't there actually relatively little moly in Schaeffers?

yes, but its a good additive, has other useful additived in it do a search on it to get the details. if you just want a ton of moly get torco's mpz, its packed with moly. Oh, also I think valvoline engine protector or something to that effect has a decent amount of moly.... cant remember the details on that one though

Moly, as used by Red Line, Schaeffers and lots of blenders nowadays is a soluble form, not a solid. In an engine, I wouldn't use any solid.

Moly additive #132 has only a modest amount of moly but also uses antimony is an similar way. Probably not be the most cost effective way to go, it may be the way to make the most of a case of rather ordinary oil you already own. I have 1 pint. Not sure what I'm gonna use it for.

For use in a tranny or rear end?

I might be tempted to use a solid like moly disulphide or even teflon ... unless it was a really touchy (late model) synchromesh box or a limited slip diff. You never know the effect that stuff is gonna have on synchronizers or clutches.

Looking to add some extra EP additives to gear oils, you could pump a couple squirts of moly-laden grease in there. Bob suggested that once, for my roto-tiller.

However, I'd simply use a premium blended gear oil like one of the Red Line gear oils (Shockproof is loaded with moly) or Scheaffer's #267 synthetic blend in any car I'd own. Use the proper viscosity (not too thick) and your fuel mileage should be the best possible.

The only reason I would add Teflon to a gear box is to quiet it down, since Teflon has NO other use than that (it can deaden noises a bit).

I would never add it to engine oil.

As far as moly disulfide powder (MoS2), how much would you use, what particle size would you purchase, etc?

As Bror said, purchase something like #267 from Schaeffer's for the diffy (plenty of MoS2), Redline MTL or MT90 for the manual Tranny.

Any one of the synthetic or partial-synthetic (Blend) engine oils from site sponsors should work in your engine.

Relative to my first post:

* car had high mileage and the engine, trans, diff had looser than OEM tolerances.

* neither the moly or the teflon products caused oiling problems with the engine (that I know of)...with the oil & filter changed each 3K miles

* base oils were inexpensive dino oils, not synthetics

* so within this context...the mileage gains were legit

* car died from a failed upper radiator hose...overheated

QUESTION: Could the same results be found by using only full synthetics?

And what mileage did they really get before adding all this stuff? Fuel line magnets, no science to support benefits.

As far as synthetics, you might have gone a bit farther without engine damage, depending on viscosity of base oil.

They both averaged 24 MPG...usually very close to that for most tankfuls.

As far as the fuel line magnets...I only mention this to be honest about the mods involved. 1 pair were an "official" set of magnets installed on the rubber fuel line...two other pairs were put on steel lines and were not set up with the south poles facing. I've never heard of what I would consider reliable reports of MPG gains with magnets.

I doubt if synthetics would have saved an overheated engine...head warped?

The question about synthetics vs this mix of additives is probably one I'd have to prove for myself...but something I've always wondered about.

This was back in my throw it in and see what happens days.

It's possible that the cushioning effects of the moly-teflon mix reduced vibration...besides lubricating?

Generally and from what little I know...I'd like to combine moly and the newer ester-based lubes like Lubegard. At least in a manual trans and diff.
