Engine Oil Supplement with Zinc Treatment (p/n 4401) | Products | Bar's Products - Premium Automotive Chemicals


I got a bottle from Oreillie's Auto Parts. I have been using mobil 1 5W-40 for the past 2 oil changes. Once I put 1 quart in with the mobil 1 5W-40 TBD oil, I noticed, with out doubt, a change in the operation of the engine. Turbo, spools off the line much faster, and start ups are faster.

I have gone ~3,000 miles on this new additive. I noticed effects right away, but I wanted to validate what I was noticing with mileage.

My previous oil changes have been 8,000miles using the bypass oil filter with great test results. This(3rd) oil I will be going 10,000 miles with a test.

I am happy, and will keep using it. It is ~10 for 1 quart.

 

One bottle per oil change? The manufacture recommends 1 bottle per 5quarts. I actually almost tried this a month or so ago.

 

Yea, I did read the back. I did not want to spend $30. So I just used one.

I plan on using 1 Q every oil change. It is a nice $10 to spend on the engine.

 

Wait I just fully read your op. You say you put it in the tank??? Fuel tank, cause that stuff should go in the oil. I'm confuzzled on this one.

 

OH DANG! that was a big mistake. It goes in the oil, not the fuel!

I am fixing that right now...

 

I took it as going in the oil. If you had put it in the fuel and were at 3000 miles on one "tank", I would be beating cheeks to the parts store!

 

ZDDP, while being a VERY effective anti-wear agent, is also a very NASTY NOx catalyst poison.

It does some very nice things in high-contact-pressure environments (gear trains, non-roller rockers, etc), but oil manufacturers had to remove it when the EPA mandated NOx catalysts in the exhausts.

If any of you remember the "motorcycle-specific" motorcycle engine oils from the mid-to-late '90's, they still had high ZDDP levels (as did diesel oils), while ZDDP was almost entirely removed from automotive oils. Motorcycle wet clutches and siamesed gearboxes LOVE ZDDP.

Engines went to roller valvetrains not because they were more efficient (even though they are), but because the lack of ZDDP in new-formula oils meant that the older (cheaper) non-roller valvetrains would self-destruct well before the warranty was up.

Those of us who don't have NOx catalysts can add it to the oil and gain benefit, without having to worry about clogging up a NOx Cat.

Be careful to look at the stuff before adding it; if it's a suspension (i.e. you can see particles/flakes in it) the filter will trap all of it long before it gets to where it does any good. The particle size would have to be less than 5-microns to make it through the filter, and you can't see that small.

Bumping old thread. Anyone use Rislone oil treatment? Thoughts? Results? Do you think it would help a partially clogged/clogging oil cooler? Thanks.

 

Oil coolers typically clog on the coolant side, so no it won't help.

 

I used it a few times. I really couldnt tell any difference in the motor. But the problem with your clogged oil cooler is in the coolant side. Not the oil side. The only thing that fixes a plugged oil cooler is a replacement with a Ford oil cooler. DO NOT BUY A DORMAN they come a diffenet gasket that is falling apart and pluging up your oil system . That causes no starts, kills your ipr valve and alot of cleaning.

 

Right. Had a brain-fart there. I knew that. Thanks!

 

I tried a bottle of "synthetic" ZDDP a couple years ago. I think it was Rislone break-in addative hoping to have some good effect on stiction. It didn't do anything I could notice and the exhaust smelt terrible. Did an early oil change to get it out of there.

 

It wont help with the oil cooler. different problem. this just adds lubrication to the oil.

 

For those worried about extra Zinc in the oil, Hyperlube makes a Zinc substitute. It's not cheap but seems to work very well. I've heard of no negatives so far and it's been out for over 6 years now.
