Synthetic Oil...

[tblazin78]

I have switched to Penzoil Platinum Full Synthetic. I have used it for the last two oil changes, and now I am hearing that this oil has parafin in it which could potentially harm my engine. Is this true, and if so, what should I do?

[ssilicon]

Use Mobil1 or Amsoil and forget about it.

[rubberman]

i use Mobil Clean 5000. You can go 5000 miles between changes. its not syn. oil tho

[rbarrios]

5000 hehe...... few of us here are going 10.5K and 14,000 miles between changes- on Dino oil.....:eek:

[rubberman]

yeah i know. i'm afraid to go that far. i stick with 5000 miles. Also i havent checked out the oil filter (since i just got the TB) but is there a larger filter you can use? like on some GM cars it takes the PF47 filter but i use the PF52 filter which is the same filter but its a longer can. just curious

Is this true, and if so, what should I do?If it meets GM's certification requirements, it should not harm ur engine.

Pennzoil is the nastiest sh*t around. I wouldnt put it in a lawnmower. Use mobil 1 or royal purple.

Per the recommendation of several oil gurus, I use only Motorcrafts semi-syn 5w-30 available at wal-mart (cheapest) or AutoZone. I then use a Purolator oil filter or and AC-Delco, whichever is on sale :D

Ive used this regimen since about 65,000 miles (bought the 'Voy with 64,000 on it) and my oil analysis that I had performed by Blackstone Labs this year was very optimistic for my oil choice! Little/no wear on my 102,000 mile 4.2L I6 :cool:

I agree with that stuff being crappy. I would change it with mobil 1 or amsoil. I use amsoil and just love it and i know its actually doing its job.

[oneredry]

mobile 1, I swear by it.

Myth: Pennzoil or Quaker State is made from paraffin's wax and causes sludge.
Truth: Many folks equate paraffin wax as the stuff candles are made of. Nothing could be further from the truth. Every oil (at least Group III basestocks, including Mobil 1)...synthetics and conventionals use a paraffins group product in the manufacturing process. Every one of them! Back in the day oil sludged up because of the inefficiencies of PCV systems and oxidation. Study up. Oxidation/leaky air filtration systems/inoperative PCV systems/fuel dilution cause any oil to sludge....oil doesn't cause sludge.

and no, this didn't come from pennzoil nor a pennzoil affiliation. just someone thats done a lot of research on oils

Funny how some people have bad luck and some people have good luck with products. I've used Pennzoil since '77 on two motorhomes and six other vehicles, including my '06 EXT. About 800,000 miles worth. I've used their synthetic for about three years. For the money it's the best you can buy. And, like the man said, if the label conforms with GM's requirement there's nothing to worry about. Pennzoil has been around a long time.

Note that I expressed my opinions without using any ****

No. Paraffin based oil has nothing to do with paraffin wax nor sludge. In fact, of the two types of petroleum base oil, paraffinic or napthenic, the paraffinic (or paraffin) based oil will oxidize at a much slower rate. Oxidation creates sludge.

Most oil base stock is a mixture of paraffin and napthenic oils. Paraffin oils are better because of their resistance to oxidation and higher viscosity index...napthenic oils are more plentiful. Napthenic crude yields more fuel than paraffinic crude, and most crude oils are a mixture of both napthenic and paraffinic oils, so the big oil companies end up with napthenic base oils. The best petroleum base oil is 100% paraffin base.

As for our fellow members on this thread that are flaming Penzoil (Platinum?) synth, just curious on what basis these conclusions have been drawn??

[edjunior]

Heh. Sounds like some of the dumb things my brother has a habit of saying. Spouting off his "beliefs" or opinions before backing them up with fact. I've used Pennzoil in numerous cars in the past and never had a problem with it. I just recently switched to Royal Purple (haven't made the switch in the TB yet...still too new!) in my truck, and nary a problem with that either. My "belief" is, no matter what oil you use, if you follow the recommendations of the car manufacturer, and the oil manufacturer, i.e., change when recommended, and do your other routine maintenance, the type or brand of oil will make little difference in the long run. Some oils may "require" you to change it more often, others less often. But the key is changing it when you're supposed to, and maintaining the engine overall.

[Bigchief]

Anyone ever tried or use Castrol Syntec? And if so what kind of performance are you getting? I'm definately going to use a Mobil1 filter but I've been trying to research which oil people are using and the types of performance they are seeing. Anyone using the Mobil1 filter???

Thanks
Bigchief

[jonathan]

Royal purple all the way ! Best oil out there. You can't go wrong with the oil. In my SS for the last 47000kms. Just keeps getting faster.

The selling point a looooong time ago for Pennzoil (made from Pennsylvania crude) was the high paraffin content. It was a higher quality lubricant because of the high paraffin content. Probably so too for Quaker State oil (Pennsylvania, right?) I don't know if these two brands use Pennsylvania crude exclusively today. I just switched to synthetic in my 2007 TB. It is better for cold weather starts and does not degrade as fast as dino oil, so I feel better about going 5000+ miles between oil changes. Probably dino oil would give just as good service for 5-6000 mile oil changes but I feel better with synthetic.

Paraffin is a common name for a group of alkane hydrocarbons with the general formula CnH2n+2, where n is the number of carbon atoms. The simplest paraffin molecule is that of methane, CH4, a gas at room temperature. Heavier members of the series, such as that of octane C8H18, appear as liquids at room temperature. The solid forms of paraffin, called paraffin wax, are from the heaviest molecules from C20 to C40. Paraffin wax was identified by Carl Reichenbach in 1830.[1]

Paraffin, or paraffin hydrocarbon, is also the technical name for an alkane in general, but in most cases it refers specifically to a linear, or normal alkane — whereas branched, or isoalkanes are also called isoparaffins. It is distinct from the fuel known in Britain as paraffin oil or just paraffin, which is called kerosene in American English. Usage of the term varies in other countries, leading to confusion about which substance is being referred to.

[Jozuah]

on another note , if the oil,either dino or full synthetic, is certified by the API and has a service rating to match your driving/usage, then its ok to use the oil in your engine. some people may PREFER to use one over the other, but the fact remains, the API certifies oils based on class and service.

That being said, would i EVER run the oil thats on the "automotive section" shelf at your local 7-11 called "10w-30",,,, no, although if its got the API donut it would be "ok" to use.

Again its all personal preference when it comes to safety of our engines.

[TrailBlazer LS]

If you change your oil the way you should you should not have any problems with any oil that meets GM requirments. I don't use Penzoil because I perfer Q state full synthetic. But it probably would not make any differance:m2:.

Mark.

I've used Castrol Syntec in my last 2 oil changes and I find great. I also use an AC Delco filter.
