I went Castrol Syntec 5W-50. Update & Weird Oil

[HangerHarley]

Turns out my Engine MAY have been Low on Oil too. Only 3 drained out! :Hide:

We thought my engine was dead. The two mechanics (we stayed there late) said it looked like "Milkshake." I explained to them that the MoS2 made it look Olive color. It did look slightly like Nesquik, though. (And the one mechanic said he thought he "Saw the water sitting on top of the Oil." I dove my Finger in there.. No Water. Also we took old Filter off, he said, "Yeah its that (censored) you put in there.)

Whoooaaaa, what a Scare!

3 quarts out.. 5 Quarts in.

Some Brake Parts Cleaner i put in the Throttle Body made it run like (censored) for 3 minutes or so, some Starts and Dies.

Oil pressure behavior is still the same, however im sure Flow is better. Castrol Syntec 5W-50 is supposed to have a HTHS of 4.1 or 4.2.

Im sure my Engine welcomed its lubrication back.

On a side note, even though only three quarts drained into the Drain Pan, the Dipstick seemed to be indicating a level full at cold. It drained out kinda slow, too. The weird Olive color, with two distinct different colorations in the pan. Weird looking Oil..

Yes, i wish i had my Camera. :doh: however, no water was found, so we concluded it was the Moly, as only i was familiar with the color.

What possibly happened?

I just got the OC, so ill keep the Board posted on the consumption, and feel.

Car runs better warmed up too.

Water sitting on top of oil?

I'm speechless.

What vehicle is this on? Do you have links to the threads with the background info

Oh, sorry. I, stil uh: since im Camera-less.

1994 Probe, 2.L DOHC ECM-chipped beater, pretty reliable, had some Consumption, and been neglected and beat on prior to me.

170,000 miles soon to be 171,000 miles.

I put Moly and 16 oz MMO in. Not at same time, of course, but MMO 000 miles after 1/2 can Moly hot Engine, 500 miles later the other half Moly, Hot Engine.

SOMETHING made the Dipstick reading False?

Only Castrol Syntec 5W-50 went in to this OC. And a Bosch filter. Seemed better choice than Motorcraft, or Fram. (Autozone Special.)

Nothing else.

And im telling you, we confirmed it was the Moly additive because the oil DID look slightly milkshakey, however it had a Swirl in it as if it were a Caramel Chocolate sucker candy, those ones that have a caramel swirl in Vanilla candy.. Thats how it looked. It looked -weird.- It was also Low. By 2 Quarts.

Where did it Go? Did it Disappear? IS IT STILL IN THERE? (No, New Oil has right level)

Wow, that was a scare. However, no Water was in fact in there. It was that "Moly" additive.

No more Mos2 for me. Nuh-uh. Its still in there.. Good additive, BAD Drained Oil Cosmetics.

Made it look a Caramel-Olive.

And who knows how long it was 2 Quarts Low, Dipstick sayin it Wasnt?

Thats a new one to me.

Syntec was chosen because:

1) Its actually a Group 3, and close to Synthetic without Being Synthetic. ("Once you go Synthetic, you can never go back." I too believe this.)
2) 5W - year-round Cold Lubrication.
3) -50 - year-round Cushion and anti-consumption.

Oil pressure Gauge be [censored]! Though my mechanic WILL put in an Ammeter, and maybe new Gauge.

This Probe is making me want to ... take up Mechanic class.

So you had an oil additive in your engine before you switched to the Syntec? I`d never ever ever put any additive in an engine,only motor oil.

Do the simple water in oil test. Heat a piece of metal so it is hot enough to boil off water in oil, but not hot enough to ignite oil. Drop a drop of the oil from your engine on it. If water is in the oil it will boil off.

An IR thermometer is a good tool to use to measure the metal temperature if you have one. You could also test it with oil that has some water in it, and also with good oil.

I would have flushed it with cheap oil before a fill of Syntec.

I do hope the Syntec does its Flushing.

Perhaps the Moly made something Gunky.

FWIW, when i explained about the additive, the notions of Milkshakey color (it was) and Water in the Oil (first thought) went away.

Moly really IS that same Color. As to the multi color, the Oil came out somewhat thick, slow, and not the ame amount as went in. It was Low level. So something happened, and it always looked OK on the Dipstick..

There have been posts about running a car with Low Oil, however how would having Three in a 5-quart Sump fare?

I agree with audi, however being the deed is already done you have a nice oil in there now to clean withOUT needing any more additives. I think you should now read back over the thread once more about the Mos2.... it should make sense now.

About "Taking up space on Resident Surfaces?"

Im more impressed about how it made the Oil disappear.

Seems I am all set with Moly.

My gf use to run her Probe so dry,that *no* oil would register on the dipstick. A quart every two weeks had to be added to that car almost. It smoked really bad and was burning a ton of oil. It was amazing how smooth it ran when I put M1 15W50 in it.

 

[rclint]

I'm not so sure the oil disappeared I would be worried about having a glob somewhere hindering the oil from draining out, but I would guess your engine consumed a quart or so of oil... I'm not sure where that thread ended up in the end, however Mos2 well I'm guessing the money you spent on the additive also poured out when you drained the oil (you may still have around 1 quart left in the engine ?) anyway with the combination of the oil, and not a lot of pressure, and what surface area inside the engine is available already being coated with engine oil the moly didn't have much to bond with....

Ahhhhhhhhhhhhh, I see now.

So it possibly "Globbed" up somewhere, eh.

I can hope the Oil carries it from the Pan to the rest of the engine, over several OCIs, yes?

Is that generally how Engines go after a Moly app?

Sounds like i made me some Moly Sludge. To be fair, it Did come out nice and thick. Our first impression was Milkshake Water Oil, akin to HG issue. Closer examination held up my insistence i added a can of weird Black Green Olive Color Moly.. and i did.

My Pan has Moly Balls?

Will it circulate, this Globule Moly Sludge that may in fact be living on the Oil Pan? And coat Engine parts?

No more Moly for me. I do credit it with my Engine starting up nice, though.

Shall i watch for the Oil darkening Quickly to a weird Moly Olive color?

I believe i see more of your point now..................

 

[rclint]

I posted in your other thread, worse case scenario is you have a moly plug of some sort somewhere, which I doubt, just odd the loss of oil after drain yet dipstick reading correct.. However also a nice mistake here would be you made a mistake measuring the amount drained, maybe the thick oil caused you to measure wrong etc... after thinking I doubt you have any problem at all.. still it's something to think about in the future with any additive.

2006 toyota camry v6. Put 5.0 quart castrol syntec... I check the oil level... dipstick show the oil level is over full mark line..

so I think synthetic lubricated better..
