Personally I will stick with that combo as well, but I must admit it is disappointing when you see the oil you use raise prices more then all of the competitors in %. Redline gallons are up 30%, imo this is excessive compared to what other companies are doing. Now, I don't have all of the info, but imo I don't appreciate that one bit. 49 to now 65, and we havnt even seen the raises from marches yearly numbers, so we will literally see what gallons end up on, maybe another 30%? It is what it is, but that doesnt mean we have to like it.

we will know when it changes on redline's website currently 65.62 for gallons. Whatever the increase ends up, we will know the %.

Im considering an experiment -

Using a few spreadsheets posted over in BITOG, Im comparing various physical and measured properties of RL to other oils. Mostly "computed VI %", HTHS and HTFS (which isn't an official stat but is calculated)

Obviously the actual additives in the oil is important, but what is interesting are the ones that come close to RL in those physical properties. Most of them are...Euro oils. Mobil 1 ESP, Pennzoil Euro L, Castrol A3/B4. One technical exception is Rotella Multi Vehicle, but its listed as a "gas or diesel" use oil, so it may very well essentially be a Euro oil.

If my Hemi starts to hate Kirkland, or I run out of it eventually, I may give one of the above a try.

Yes, funny how the euro oils are now mostly "thick" oils. Seams like america is irrational and euro is more reasonable on oil viscosities, how did that happen? nono, don't answer please, just say'n

Used motor oil cold flow, I do wish there were more of these out there. It does show the 0w30 kept it's cold flow advantage over 5w30 even at the end of the interval?

Is that in Portuguese?

I seriously doubt amsoil is out of the filter market, try emailing them. They have way more invested and surrounding filtration then most companies. Supply line issues murph would be my guess.

Fram is in the middle of changing over the Ultra to non-wire-backed media. I can't find a Fram Ultra 7317 ("larger" filter for my G37) anywhere.

I can find the Endurance, which looks eerily like the SRT filter for our trucks (scalloped center tube, cant see the media).

Wonder if Amsoil is shaking up some of their filters too.

I wasn't sure where to put this and I suspect the answer lies somewhere. I am going to be lazy and just ask outright. I see some synthetic oils where the same oil is available in two guises. For instance a "Full Synthetic" and a "Full Synthetic, Dexos 1". Both in the same weight as well. An example would be Quaker State Full synthetic in 5W-30.
Reason I ask: Throughout the years it seems that the oil formulations began to change to accommodate manufactures requirements. May it be to prolong the life of components like catalytic converters or perhaps an attempt to meet mileage goals and / EPA requirements. Lately there is the GDI and gas turbocharging requirements. My thoughts have been that this was not always a good thing for us the consumer. Especially if you are someone as I who tends to keep and run old iron. I also own a 1988 truck powered by a Carbureted SBC engine.
I now own what I am quite sure will be my last purchase for a truck. My Pentastar powered RAM is neither direct injected or turbocharged. I thought I had settled on an oil that I was happy with but it is no longer produced. So I am on the hunt again. I don't think my driving habits maintenance schedules and the Pentastar warrant going the expense of boutique brand oils. Because of my cynicism in regards to the evolution of motor oils I question if for my particular engine, driving style and **** maintenance practices, I should use the latest formulations that are designed to deal with conditions that I don't have to deal with.
If you made it through all that, what I am asking is just what has been deleted or add to the same oil when they slap a Dexos 1/ Gen2 label on it?
Just like more or bigger is not always best for everyone perhaps in Motor Oils newer may also not be best for everyone.
Thanks folks, Stay safe.

Dexos is a good thing in many ways, the most important is uniformity in the additives plus some stay in grade features to the viscosity. It is on most oils, but when you pair that with mercedes, VW, and porsche specs you do know you have a quality oil. Plus, as far as CAFE goals, it is as easy as changing viscosity and going thicker to squash that bug. Unless you use 0 winter rated oils, you can assure yourself a decent quality oil by using that dexos, this spec has forced manu's who spec it to have good oil, and even forced oils to use less additives if they previously used more. If you want heavy additives, use an additive or boutique oil. But, that engine doesnt have the same challenges as the hemi, you might consider kirkland 5w30 (or super tech, havoline, or other cheap dexos oils) and because it is so inexpensive you can shorten your interval up, now that is a good strategy? Dexos makes a shorter interval and a cheaper oil really look like a great strategy.

Not sure of the shorter interval and cheaper oil is a good one for the HEMI though. Someone told me that if I went with Castrol Edge 5w30 or 0W40 and used shorter intervals of 5000kms I should be fine. I'm not too convinced considering what happened with Castrol Magnatec.

I have always been a fan of shorter intervals if it was cost effective and a decent oil was used. When I was running my other truck regularly and there were never temperature extremes ( I only drive it during warm weather months ) I would use Rotella 15W-40. I have had very good results using the Rotella even in a BMW motorcycle.
I have been considering the Quaker State and just noticed in another thread the excellent UOA posted with that oil. A high mileage interval at that!
Quaker State is a rather strange road for me to travel as I swore many years ago I would not use it. It would definitely result in an initial start up "clatter" in a 1965 Mustang I owned. I swear, drain it out and put in another oil and the start up noise would go away! It is strange how we formulate beliefs and make our decisions sometimes. Soooo, I went to find some Quaker State Full synthetic which gets some good reviews and upon VOA appears very similar to the Rotella Gas truck that I was using. I believe it was once called Quaker State Ultimate durability and is now simply called Quaker State Full synthetic. HOWEVER, I found two different Quaker State Pure synthetic oils available. One without Dexos1 and one obviously labeled Dexos1.
If something that is GOOD for my non- DI, Non-Turbo charged engine was removed to meet the Dexos1 requirement I would consider the non Dexos oil.
I understand that I more than likely can run the Dexos rated oil and probably be fine. Just nit picking I guess. And, the other is available. Both are the same price by the way.

Like everything I do I tend to use the exceeds part of the meets or exceeds spec. But the merc spec oil is cheaper then the 5-20 signature oil.I’ve been using the 0-40 and 5-40 on a merc diesel and my 2.0 t Audi for 10+ years image.jpg

It's gotten to the point where you could write a college thesis on engine oil selection on an annual basis.

This is ridiculous for mass market consumer products. I know because I used to work in this field.

It's clear to me government is regulating ICE engines out of production with insufficient replacement and infrastructure. And I'm not culturally anti-government as an ideology.

God help us.
