First, I know this topic has been discussed ad nauseum but I'm not sure I've read anything similar to what is said in an email exchange I had with Pennzoil. The content may apply to RX-8 as what is stated is that Pennzoil Ultra burns cleaner than other oils.


Second, I no longer own an RX-8 (yes I loved the car and did not like parting with it).


Finally, the only edit I made to this email exchange was my name was removed. Otherwise it's identical.

So read on if interested.

// From Pennzoil

Dear XXXXX,

correct, only the 5W-30 for your HTO-06 specs.

To answer your other questions; in the engine the seal that keeps the
oil out of the combustion chamber is the piston ring. However, in
the in the lubrication some tiny amount always get across as the ring
goes up and down the cylinder wall. Thus, the combustion process
will burn off the oil and exhaust it out of the vehicle.

Our Pennzoil Ultra is designed to burn Clean; not like other oils out
there. Thus, if it burns clean (hopefully you are using good quality
gasoline), then it would not leave residue in your "crowns". By
working closely with the cleanser in the gasoline, then your engine
should be clean and remain clean.

Regards,
Technical Service, sn

// TO PENNZOIL

First let me say I know that Pennzoil ultra is amongst the top tier
oils
available, if not the top oil available. I use it in my Acura RDX
(HTO-06)
and Mazdaspeed 3.

It is however becoming difficult to find at Walmart and is
exceedingly
expensive at Pep Boys.

I have a couple of technical questions.

The Pennzoil Ultra line of oils promote its ability to keep engines
factory
clean, especially on the pistons.

1. How does oil "clean" or keep clean piston tops/crowns (since oil
isn't
pumped into the combustion chamber)? Is this done via oil vapors
that reach
there through the PCV?
2. Related to question 1, does Pennzoil Ultra help with carbon
deposits created
on the valves of direct injected engines in a way similar to how it
helps keep
piston crowns clean?


I have one criticism. While I'm a big fan of Pennzoil products and
use them
almost exclusively, the website is in a very poor state. For
example, the RDX
oil recommendation is 5W-20 and mentions nothing about HTO-06
although Pennzoil
does print compliance with that spec on both Platinum and Ultra
bottles.

To be sure the manufacturer recommends HTO-06 compliant oils and
those only
come in 5w-30.

Thanks in advance for your answers.

 

WTF?!?!?
Gotta say ... very ingenious way to spam the forum

Reported

 

The Pennzoil name is owned by Shell Oil. I don't think they need to spam our little forum.
digitalSniperX1 himself has a track record on this forum and not as a spammer.
Now, an email message from a company is going to come from the marketing department and will sound like spam.

 

Right, I will buy that.

Still doesn't explain the "out from left field, wtf is this thread about" problem.

I'm not even sure what the point is?

 

Lil strange there op

 

There was no attempt to sell anything here...my apologies for not being clear.

There are many discussions on this board about carbon accumulation in this engine which results in lost performance and sometimes results in engine failure.

There is also the seemingly ongoing synthetic vs. conventional (oil) debate.

Having said that, this company (Pennzoil), claims its formulation burns cleaner than all other oils and is a synthetic.

And burning oil in the rx8 rotary would almost certainly be a source for carbon accumulation.

If that's no longer an issue or topic of discussion on these boards, then the mods should kindly delete this post.

Otherwise owners may wish to look into it a little more.

 

Sniper,

Great info from your OP

Thanks for sharing your email correspondence with Penzoil (& kudos to Penzoil for anwering somebody's "random" email)

Now, to pacify the "Forum enforcers" you can change the original thread title to something like "Oil info: got an email response from Penzoil themselves"

 

Thanks WDR....I apologize for the somewhat obtuse thread title.

If I have the privilege to change the title then if anyone cares to do so, tell me what button to press and I'll change it to "Pennzoil claims its Ultra burns clean" or something similar.

 

You don't have that ability, but I do.

 

Thanks fella. Not sure it's of any practical use for an RX-8 since it's not widely known how much oil burning contributes to the carbon accumulation.

 

What?
It's not widely known.... Seriously are you retarded?

For the luv of all that's holy you could have posted this in a number of threads already discussing oil but yet you don't.

Then you say " Not sure it's of any practical use for an RX-8 since it's not widely known how much oil burning contributes to the carbon"

Really ... ******* **** **** **** REALLY ?????????????????????
NO ******* none of us have heard of carbon ....

I don't give a ratts ******* *** what the ******* mods think ... I ******* hate you .... I'm watching all your posts moron.

 

This thread is getting hilarious...lol

 

+1 for unintended hilarious thread

EDIT:
On a side note, I'm saying wcs is drunk. It IS about beer:30 . . .

 

 

normally youd get a warning or at most a 3day ban for that. but since you dont care have a week off

You may find it funny. I find it sad. It's stuff like this that really wrecks what is otherwise a great site.

 

Even if it was spam... it would just turn into another oil thread that concludes with no answer and everyone buys a completely different oil for their own reasons. This would be the worst forum to try and advertise for oil.

 

I have never liked Penzoils products. I have opened up piston engines that used their non synthetic products and there was sludge all over the place. I realize that the synthetic is not an apples to apples comparison, but I am still hesitant to use their products. Perhaps some of you have had better luck with these products and would care to share that information/experience?

 

I've opened up engines with pretty much every oil, and found lots of sludge. I've also opened up engines with pretty much every oil, and found very little sludge.

There are about a dozen (or more) much more significantly contributing factors than the label on the bottle.

 

I actually like Penzoil products.

& I think its awesome that they answered Digitalsniper's email.

I do find it kind of suspect that their synthetic 4-stroke would burn as clean as they claim (otherwise it would actually be a 2-stroke oil) But if it does burn cleaner than oters...

I also like Castrol GTX
& most Motorcycle (Hondalube/pro-oils or Yamalube in particular)

 

DigitalSniper, Pennzoil is just trying to sell you on their product.

As far as your original questions to us... The oil in piston engines does not enter the combustion chamber as a vapor. It does not get there through pcv either. It makes its way up there via the crankcase, up the cylinder wall from below as it is thrown around by the crankshaft and piston rods. It then finds its way beyond the piston rings because they are not continuous, solid rings; there is a small gap that allows the rings to be compressed when installing the pistons. They then expand after installing to provide a reasonable seal.

Basically, their shape looks more like a "C" than an "O", if that helps you to visualize how oil can get past the piston rings.

 

i got a 96 chrysler lhs with 250,000 ml. iam the 2nd owner, all i use is pinnzoil high mileage. i just replaced cam, & crank seal, timeing belt, water pump & oil pump. that oil pan was as clean as u could ask for. in my rx-8 i use pinnzoil 5-20 ( for winter ), no complantes here.

 

Well said. Except a "C" may be a little misleading. A "C" has a large gap (like 30% of the circle), whereas a piston ring has a very small gap. One of the tips when assembling an engine is to make sure the gaps in the piston rings (each piston usually has three rings) are offset from each other.

 

 

Wow, the funniest thing about this thread is the Chrysler LHS with 250k on it. If true, someone should call Guinness.
