Not true about moly in DT40. These UOA reports from my Cayenne where I used DT40 and nothing else show over 400 ppm of Moly. (Last 2 are DT40. First one is what was in the car when I bought it).

 

See the DT40 UOA I posted. DT40 has lots of Moly. Mobil 1 has hardly any of any. I've had Mobil 1 break down to a much thinner viscosity in as little as 3,000 miles so unless that's your change interval, use something else.

 

 

That's the old formulation of DT40 (I notice your report was from 2011). The current version is what I posted, and after 5000 miles of use.

 

Do you mean the Mobil1 5W50? The DT40 was sampled in 2019. I haven't heard of any new formulas of DT40.

 

Yep, my fault. Thought that UOA was for the DT40, but I didn't look at it carefully. 2019 is the current formulation. I think it changed 4 years ago or so.

 

I only put that comment there in jest. The advertising world is full of endorsements of products never used by the endorsers.

Seafoam seems to be universally well thought of. I use it in my 2 cycle and 4 cycle lawn implements. Do you ever recommend using it in the flat 6 fuel, for injector maintenance, i.e. lubrication? Especially the DFI injectors?

As seductive as moly additives are, it seems like both you and Charles have both advised against adding them.

Or all additives verboten?

 

Thank you
Can you please refer me to a Sea Foam model that fits my 9A1 997.2 engine.
I was debating whether to purchase the original Porsche fuel additive.
Thanks

 

BTW, I checked now and according to the Owners Manual Book of Porsche 997.2, it is stated (several times) that Porsche does not recommend the use of fuel or oil additives.
That's true for 997.2, I do not know about the other Porsche engines.

 

Of course, I can't speak for Jake or the team at Flat 6 Innovations, but I don't think Jake is recommending adding Seafoam as a regular "additive" to fuel; but instead, to remedy a fuel system problem. For example, I first met Jake at a Cars and Coffee event. I had taken the "new to me" 996 coupe. He asked me to start it up. I started the car and he put his hand on the top of the driver's side window. He then looked at me and said, "you have a clogged fuel injector". He told me to look at the window that was shaking. He then told me to run two cans of Seafoam on a low tank. I followed his directions and the car smoothed out. He later tested the car for rough running and fuel trim and it passed with flying colors. After that, he recommended that I run only Shell V Power in my car instead of other brands. That was three years ago and I don't run any other fuel other than Shell if I can help it.

I have found an oil and additive I like and use: Liquimoly Leichtlauf 5W-40 and Ceratech. Why? I dunno. What makes it good? I dunno. Is it bad? I dunno. Can I engage in an argument about it? No.

Comment of the year! Love your forthrightness, Bruce. ha!

 

Oh, so I neglected to say why I do it!!! So, here ya go: It entertains me.

OK so I can't help but wonder about a few things. Sometimes car manufacturers have emissions and environmental regulations to think about. So Porsche might just be trying to adhere to a green stance when they say they don't recommend oil additives or fuel additives since those may adversely affect the environment.

My thoughts on motor oil have to do with cost. What if Mobil1 or Liquimoly or Motul or whoever you use could make a super oil but they don't because it would cost $25 a quart? They are in business to make money and the name of the game is money, so they have to be able to sell whatever they make. Cost to consumer MUST be a consideration in addition to all the others. Liquimoly makes additives! They are an oil company that makes additives. If they thought adding aftermarket additives was a bad idea they wouldn't make them. I put it to you, that the additives work, but cost a lot, so they let the consumer decide on the relative level of protection based on their willingness to pay. I would really love to know if my 9A1 engine that is noticeably smoother running on Ceratec would be putting out less power than it would without.

 

I never care what Porsche does, or says. Never have, never will. I don't even pay attention to those things, as it makes no difference in my world.
Find an API parting on any additive that you can buy. You won't.

Do whatever makes you feel good, just know that in the world where we have advanced knowledge, and the abilities to evaluate the behavior changes/ impacts that additives make, that none of us use them. I can't think of a single peer that doesn't think they are a liquid band aid, or sugar pill. I have broken the hearts of multiple oil additive suppliers over the years by sharing unarguable, direct results. One just last month sent us a bunch of free stuff to try. I tried it, and got a weird dyno result, where the plots were all jittery as soon as it was used. I knew what caused this, so I asked the head honcho (who kept bothering me for results) for a "VOA" of the oil. He messaged back and asked what that was! I then told him, (virgin oil analysis) and things have since become radio silent. I decided to get my own VOA, and UOA, so I'll tell him what he has in a few days. Whatever it is, it sucks.
