I have run Pennzoil Ultra in my '13 since it had 1000 miles-when I drained the factory fill oil. I had a very slight valve noise from day one with 37 miles on it. After I changed the oil using the Pennzoil Ultra and a Delco oil filter, it has been whisper quiet ever since. I now have 7500 miles on the odometer. My truck seems very content with it.

IMO when it comes to brands any synthetic is great, but what makes a big difference is a quality filter.

Agreed. A good filter makes the world of difference. I run WIX filters in everything. I run Valvoline or AMSOIL, depends on the toy.. Usually full syn. In my special toys I run AMSOIL full synthetic and full syn filter. AMSOIL full syn filter and oil will actually clean out some of the gunk on an engine with alot of miles. I'm a dealer of AMSOIL as well if you would like to try them I can get you dealer cost.

 

And not to start a fued or be rude, but Penzoil is junk in my opinion. I have also had 3 engine mechanics tell me they see more sludge from Penzoil than anything else. BUT, that can be affected by the user as well.

A test was conducted a couple of years ago, third party, regarding film strength of various oil brands, with some interesting observations. The discussion goes into great detail why even the film strength would be important, and how it is but one aspect of what an oil has to do. Might make for a good read for some folks here. Might even cause some folks to rethink what they are using. You be the judge.

 

Wes, see which one came in first! For the sake of full disclosure, I use none of the oil brands that got tested (sigh). Really wish they had thrown the one I use in there so I could see the results.

So many factors that can effect a vehicles oil. Pretty much for the most part, most out there change their oil at or around 5k miles. Most off the shelf oil will serve well.

 

Schaeffer is a good oil, just wish it was easy to purchase at a local auto parts store. One would think for as long as it has been around it would be easy accessible.

 

For the most part the one that puts out the most money on marketing sells the most product. Just a simple fact of life. Hence why Mobil 1 is so popular. They advertise like crazy. Nothing wrong with Mobil 1.

 

I have noticed that Royal Purple has stepped up their marketing. I have seen their name in some of the latest movies that are out, one being the latest Die Hard movie and World War Z, a display of Royal Purple motor oil in the middle of a grocery store.

Dang! Well I'll put my foot where my mouth is. Honestly its all lube. And we all pay too much for it anyhow. I'll keep my supersticious thoughts about Penzoil and run my red white and blue AMSOIL and Valvoline!! lol

Yeah, I really have no bias either way. I use Schaeffer oil based on reputation and quality, but also because I can get it at wholesale price and delivered free. One of the perks of a commercial account and buying a lot of product. If I was buying like most folks, for a personal vehicle or two, not really sure which brand I would buy. More than likely Amsoil, because I already use a couple of their products for niche applications.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      Gas Prices

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.
