Another engine oil thread ... What do you use?

[Jeff_oddo]

Just changed my oil yesterday.. switched to Pennzoil Ultra Platium 5W20.

pennzoil Ultra 5-20 is rated at 86,035 PSI shear protection. Good shear protection rating.

Quacker state Ultimate durability 5-20 is rated at 121,396 psi shear protection "incredible protection rating.

Well uoas come back better then qsud by quite a bit with pennzoil ultra. That link youve passed around the past few days isnt the best way to pick out oil. If you venture over to bitog youd find that out. Dont misunderstand qsud isnt crap but its definitely not better then a handful of other offerings available. Its a nice improvement over any motorcraft oil though.

Not sure how one can argue that an objective analysis of shear testing in at controlled environment with oil at the temp like it would be in the motor is not relivent. The ability for an oils film to prevent metal to metal contact is it's number one job.

Most of the name brands manufactures do the same shear testing with there oil compared to other, but don't produce a PSI rating, but rather a wear scare measurement. They don't even heat the oil to represent its actual ability at operating temps of 230 F. The engineered test above goes on to test all these oil at even more extreme temps of 275 F like in racing, were many oils start to loose there ability to prevent shear.

I would believe this study over anyone here saying that brand X has always run great in there motor and higher viscosity always offers better protection becuase it's used in race cars. Furthmore what is the alternative to independent testing data. Are we to believe the snake oil claims of many the major brands that have name regontion and unlimited $$ for advertising market propaganda. No wonder everyone has an opinion on oil we are all led by the noise with myth and misinformation.

Not saying that all top name brand oils are bad here, just that they don't all offer the best protection for $$ spent. And some offer way below what they advertise.

If qsud offered the best protection its uoas would be putting amsoil etc uoas to shame. His blog has been argued to death there. Most post have shown his test to be a poor way to pick oil. There are others that have a very similar field of experience that has even said to not pick your oil based off that blog.

I'm interested in what is the background of (bitog) Bob I'm the oil guy forums is this independent ormis it sponsored. Also when you say his blog has been argued been argued to death and most have shown it to be a poor way of testing. Who are you referring to when you say "most"? Are they experts in the field or people like you and me. Just curious, I'm not saying g I know everything and my mind is not closed here.

It is a full of people, greenhorns, field experts, veteran oil guys that may not have gone to school but have decades of experience. I would venture to say you and i are not quite on the same field as far as oil knowledge but i am most certainly not a person in the oil field. Tons of independent people getting uoas, cutting open new filters and used for examination for pleate count, overall construction, checks for tears in the media based on duration used etc. Any type of oils is debated as well as filters. There is a lot of know it alls there that know little. Youll find out quickly whos someone with knowledge and who isnt. Just as any forum there is more that arent knowledgeable vs the people that are. But the uoa numbers and other testing results are there, it just takes the know how of how to know what uoa results are good and whats really not. :cheers:

Also a lot of these guys get enjoyment from testing their oil regularly or multiple times during a 7500-25k oil change. Youll find those pro synthetic and those pro dino oil.

Alright thanks Mustang-guy, I've done some research on Bobistheoilguy.com forum and it seems like you said, it's a mix. Bob Winter's AKA (Bob I'm the oil guy) was a distributor for Schaeffer's Specialized lubricants who started the website in 2002 sold to Tony Riek who has since passed away and the website is now owned by his wife. My question is where is the expertise and unbiased knowledge coming from on this site now. Seems to me it's mostly people like me and you, but then also some in the oil industry who have something to gain by selling and promoting their products and data. The website clearly isn't free of unbiased influence from major sponsors like Amsoil, who has been a sponsor since early 2000's, and who's oil is highly promoted on the site.

I guess we may see things differently in all this, but in my opinion I'll take the empirical data from an mechanical Engineer who's testing is not affiliated to the oil market and its big money and advertising propaganda. Read for yourself here on this link provided from an AMSoil sponsor why they endorse and contribute to the Bobimtheoilguy.com website/forums. Even AMSoil warns to beware of miss information on that forum.

The point can also be made that UOAS or Oil analysis testing like Blackstone or others isn't the end all be all in proving or disproving an oils ability to protect against engine wear.

I am interested if you can point me in the direction or explain how you compared uoas from (QSUD) Quaker State Ultimate Durability to AMSoil and is this comparison 5w20 for both? You insinuate that if QSUD really was better in regards to shear protection it would have better results in the Oil analysis. So does this mean that the oil analysis you speak of is from the same motor with the same weight oil run under the same conditions?

 

[hegel]

I just ordered 4 gallons of Amsoil XL 5w20 and two oil filters. Normally I run Mobile 1 but I have a friend with a commercial amsoil account and was able to get the amsoil cheaper. Went with the XL instead of the signature purely because of the cost. the XL still has excellent properties and honestly I wouldn't push it to the 25k OCI that the signature is rated for anyways.

 

[randotheking]

I still have a bunch of Mobil1 full synthetic 5w-20 left over from my 2013 3.7L, so I guess I'll be putting that in my 5.0

I found the Rat Blog oil tests pretty interesting and it's definitely good information. But these tests are done in a short period of time, not the equivalent of daily driving over 5000-10000 miles. This is where oil samples would be a better indicator of actual oil performance.

Bob is the Oil Guy certainly has many enthusiasts without engineering backgrounds, but there are a LOT of "oil geeks" on there with those credentials and some of the rocket scientist type. Some of their discussions can be pretty intense.

One of the things that is great about BITOG is all of the oil sample data posted. While maybe not as lab scientific as the Rat, this is real world data in actual service. There are samples from all kinds of duty in there. From racer types, to the 3000 miles change guys, to the once a year (or longer) folks.

I posted an oil sample from 19000+ miles on a SUV I had for the Amsoil SS stuff. It performed great by all measures and probably could have ran for much longer. Point being, the Rat tests are a great tool to have but certainly not the definitive answer on how an oil will perform in the real world.

His testing shows how a fresh oil will perform under a small moment in time or temp spikes. How will that same oil perform over miles and time? Will the additive package hold up? Will the viscosity remain relatively unchanged or provide wear protection as it ages? Will it burn off and evaporate or will it not?

When I owned my own Class 8 tractor, I bought it used. It was running on fresh oil that was likely a standard fill. I ran it for about 20k then changed it out, along with the transmission oil and differentials to Amsoil all around. I ran with loads that were regularly at 75000+ GVWR in southeastern US temperatures of 90+. This simple swap not only improved my MPG from 6.5 to over 7, but also reduced my operating temperatures. I had one steep hill that I crossed daily that would always spike my engine temp and kick my fans on with dino oil, but with Amsoil the temp needle didn't even move. I ran 50k on the engine oil, and the only thing out of wack was soot levels which could have been controlled with a bypass filter system or if I had changed out the spin on filter more regularly. The rest of the oil sample came back with minimal deterioration and likely could have been ran for much longer if I had better filtration.

Those are a couple of pretty extreme examples of how oil can perform in the real world and why I trust Amsoil. I have a sample coming up in the spring when I'll change it after a year with the Signature Series. It should have about 10k on the oil by that time. I plan on trying the Pennzoil Ultra at that time since it's easier to obtain and cheaper now that I've let my Amsoil membership go. It'll be another year before we see that sample, but it'll be something to compare to.

Amsoil is a good for sure and many others out there with big name recognition. Oil sample testing data is a great tool as well no doubt, but comparing an Oils sample data against each other would only be fair and conclusive if they all run in the same motor under the same conditions correct.

540ratblog also has done long term testing on those oils to show that over time and use they still provide the same level of shear protection.

Just did my first oil change using Pennzoil Ultra Platinum and the the OEM Motorcraft filter. Noticed right away the engine was a bit quieter and smoother.

 

[Coyote Red]

I've researched this subject and have come to the conclusion that Pennzoil "made from natural gas" 5w30 8qts. with a 1/2 qt. Lucas oil stabilizer is the best route for my wallet. I use the Ford "Racing" oil filter for the increased capacity and "bypass feature". Upon my last change the 8 qts. wasn't full so I added Lucas to top it off. Works for me, I did the research. Best bang for the buck!
