mobil super 5000 vs pyb

[BillyTheKid]

I am no oil expert here, but my vote goes to the new Mobil 5k. I have used both and am pleasantly surprised at how the Mobil did in my vehicles (nope, I am not a UOA guy) and the price cannot be beat at WM now. It is under $13 for 5 qt! The PYB did fine for me too in the past, but personally the Mobil ran quieter and was run longer, and it saves $3 or so per 5 qt. That is $3 extra to play lotto and dream in my pocket - LOL

As 2010 FX4 posted in his research, it has proven to be pretty stout stuff.

dnewtown3 and 2010FX4 are a breath of fresh air. Love the logic rare I agree with anyone on the internet but so far these guys are pretty clear and on the mark IMHO,seperates what you hear in a diner vs what is real and how to get to the truth.Hope it stays that way.

 

[nomochevys]

Im no oil expert either and have run both in a GM 4.3. I could not tell any difference. That said I feel like I could push the PYB a bit further based on what I have read on this board.

You know what? I just realized you are finding the same as Concumer Reports did re. NYC taxis, the difference between convential and syn. re. wear,

almost does not exist in these oci's .

I am not talking about stuff from 2003 I am talking in the last year. This oil gets great uoas where??/ Unless it is PP or Amsoil, Mobil etc you cannot ever find enough uoa's that would support "it gets good uoa's!!"Another example on how hard it is to get a conclusion from web sites on the internet.

I can only speak for myself, but part of the problem is that **most** run synthetics and therefore it is difficult to find any number of conventional UOAs. I believe that MS5K held up just as well as Pennzoil Ultra in my FX4 for 2.5x LESS than the cost of Pennzoil Ultra. I am 60% on the way to a 10K run of MS5K in my FX4 and will post that UOA when I reach the mark.

Here are 3 UOAs of MS5K versus Pennzoil Ultra: ---> MS5K versus PU UOAs (FX4)

Great thread with good info. I have a question though. In my 04 Ascender with the GM 4.2 Liter In-Line 6 I always run synthetic 5W-30 either Pennzoil Platinum or Napa Syn and go 5K between oil changes. Can I accomplish this with either MS5K and PYB? Have I been wasting my money on synthetic oil?

For a 5k OCI you probably have been wasting money. I would either switch to a quality conventional such as MS5K or PYB, or stretch the OCI to at least 7.5k miles. By running the synthetic 7.5k, you would have a minimal difference in oil cost over 15k miles and would have consumed 1/3 less oil.

I would go with PYB because I don't use anything by Mobil anymore. Lets be honest. Very few people actually keep their vehicles long enough to find out if one oil was better than another or even run one oil long enough to find out how it does long term.

Back in the early 90's when I bought a new S-10 4x4, I obsessed about what oil was the best and worried if I was using the best. This was before the internet and any info you got about oil was from broshures or from the manufacturer itself.

I chose Mobil 1 and used it religiously for about 7 years before I discovered oil analysis and learned that my favorite oil wasn't performing very well in my truck(98 Chevy 5.7L) that I had and still have today. This was a truck that I bought new and was religious on oil changes and maintenance. I ended up switching to a conventional oil and my oil analysis results improved and my engine was a lot quieter and used less oil. I also discovered the same thing with the 98 Grand Prix GT my ex-wife drove that we also bought new and took excellent care of.

I still have this truck today and only use a conventional oil in it. PYB currently but have used others in the past. Truck still runs like new and the engine is quiet.

I personally feel for me that synthetics are not cost effective and I have not seen any data that shows me that synthetics prevent enough wear to matter. My experience has also been that synthetics have not made my vehicles run better than a conventional. The only way I will run a synthetic is if I ever buy a vehicle that the manufacturer says I have to.

I am no where near an expert on oil and this is my own opinion from what I have read on the internet and videos I have seen. It seems the biggest difference between Synthetics and conventional's is at start up. Where a synthetic oil will flow to all parts of the engine in 5 seconds and a conventional will take 10 seconds. There is more wear on start up with conventional's. How much truth there is to this is up in the air. Just my thoughts.

i will say this : i agree with you but I like to use synthetic or @ the very least 50/50 in the winter for flow pumpability. otherwise I use conventional all year round. no need to go syn, i change often with quality dino and i like it that way; i would just be wasting $ otherwise, like you have said.

Synthetic may flow better on start up, but oil flow is not the only important factor on start up. The polarity of the base oils is also very important. A more polar base oil is going to adhere more and bond more to metals on critical engine components, so provided the highly polar base oils have good film strength, they will protect until the engine oil is flowing properly. As a result, some group II's may function better than some synthetics on start up.

That's too much to consider. You're saying dino might actually flow better at start up? I will ignorantly keep using syn during the winter and sleep better at night.

It's all about how you sleep at night end of question

That's Mobil TriSyn synthetic. It is a mix of GIII,IV and V. A pure PAO (G IV) not necessary be the best for better motor oil.

To me, its the capability of extended OCI's with the synthetics.

 

[crazyoildude]

no mobil 5000 anymore..

WM is getting up there in price you can tell which oil is selling less because the price went up by the amount of dust on the oil container
