Penzoil synthetic

quote Steve A W:

I tried the synthetic blend a few years ago.
It stank ❗ ❗
It smelled worse than the cat box when the kids were supposed
to care for it.

What brand was that Steve?

A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.

A discussion from S&F, note Jay Smith Racing comments throughout, he repairs a lot of service engines and sees the innards. Seems the Pennzoil semi syn XLF or their Premium Plus are favorites and Jay recommends them:

Of course oil discussions are filled with a lot of IMO like best beer discussions. I use the Penn XLF in my Merc and Yamato 7000+ rev outboards no issues with oil.

Jamestown Distributors sells full synthetic on-line. The brand is Sierra around $12 a quart available in quarts and gallons.

It was Pennzoil synthetic blend.

Thanks Steve. If I do try it I’ll only be getting a Quart.

Thanks Jim for the heads up.
I run 3 oz. per gallon in most of my motors which is around 42 to 1.
At $ 40.00 gallon I’d be looking at about a $1.00 per gallon for the oil.
I’ve got enough Pennzoil left for the next two years. Time for me to
investigate suppliers and give it some thought.

I use Mercury Quicksilver Full Synthetic PWC 2-Stroke oil states right on the jug, " Can be used in Oil-injected OR Pre-mix applications.

I buy it at Walmart

Internet search shows Walmart price is $28.56 a gallon.
Not much more than the Pennzoil was at Menards.
Looks like that has moved to the top of my list
when I need some. If they still have it by then.

Below the Mercury PWC 2 stroke 2T oil synthetic ingredients according to the MSDS from the Brunswick Co archives (link below). Lots of +/- in those % specs hard to know what you get ❓ Looks like they use Group III base stock and "if refined enough" it qualifies for a synthetic ❗ Based on the Wall Mart price it is definitely blended for cost control. Group III base oils are sometimes considered full synthetic, but are still classified as highest-top-level mineral-base stocks according to the API. Lots of outboard and auto oils on the market use Group III and blend in other stuff and they get to claim full synthetic to compete in the lower cost category. Not really the same as a pure Group IV PAO base stock synthetic oil. The PWC oil looks like a blend of Group III and IV stock and probably mostly III with a lot of +/- in the brew. Maybe like the cognac difference between Remy Martin XO and Remy Martin Louis XIII, no real comparison once XIII is tasted ❗

Component Name(s) %
Highly-refined petroleum lubricant oils 30 – 60
Distillates (petroleum), hydrotreated light 10 – 30
1-Decene homopolymer, hydrogenated 10 – 30
Polybutene Synthetic 10 – 30
Ester Proprietary 10 – 30
Ingredients Proprietary 1 – 5

Specifics here scan down for PWC 2-STROKE FULL SYNTHETIC (8M0058907 – 8M0058908)

Wasn’t aware of all the products Brunswick makes until this link popped up.

So you are saying it is really a synthetic blend and NOT a full synthetic?

Guess I had better do my research to determine if one product is in fact full synthetic instead of "claimed" full synthetic.

Thanks for the heads up

No it is not a synthetic blend.

From Wikipedia (not that they are the last word 🙄 but convenient at time)

https://en.wikipedia.org/wiki/Synthetic_oil

"Semi-synthetic oils (also called "synthetic blends") are a mixture of mineral oil and synthetic oil, with no more than 30% synthetic oil, which are engineered to have many of the benefits of full synthetic oil without the cost. Lubricants that have synthetic base stocks even lower than 30% but with high-performance additives consisting of esters can also be considered synthetic lubricants. In general, the ratio of the synthetic base stock is used to define commodity codes among the customs declarations of tax purposes."

Boy there is a lot of behind the scene juggling, not 😮

Based on API standards for highest refining of Group III base stock that can be called a full synthetic for marketing and that is what the Mercury PWC oil is relying on. That does not make it a real Group IV base stock synthetic oil but they are allowed to call it full synthetic.

It is not easy finding out what is in the brew of these oils. The MSDS reveal some of it but in a lot of cases they state proprietary. As you can see in the ingredients I posted for Mercury PWC oil there is a lot of +/- stated to keep the real brew secret.

Not an Amsoil user but they claim Group IV PAO base stock in their oil and that supposedly makes it superior ❓ Also no MSDS on their products that I can find, disappointing , top Secret again ❗ As for car and outboard oils I like the stuff made by the oil makers and marketed under their name. Mercury, Yamaha, OMC, etc have the oil companies make their oil based on what they want in it from their testing, etc. Not saying that’s bad they are good oils I just prefer the ones directly from the refiners.

Like I said in my 1st post it is hard to know what you are getting in the can 🙁 , maybe they even put GMO’s in there ❓ 😆
