Quick question for all the "mixers" out there. Can you please tell me why you guys are mixing different brands and grades of oil. Are some of you chemists out there or are you just experimenting. What are the benifits OF mixing and what is the best "HOME BREW"
Question for all

I'm mixing one quart of RedLine with 3 quarts of either Group III oils or Full synthetic. I like the Idea of a higher level of Esters (RedLine is ester based) Also the level of Moly is much higher (Although I really am not sure of the benefits of higher levels of moly)
Ugly is probably right here

I am not a chemist or tribologist, myself, therefore I don't mix.
My theory is....use it only straight, unless you want to use LC or MolaBrew as prescribed by the real experts.
I see no advantage to amateur mixing. It's a hobby and generally causes no harm unless you go too far afield.

Thats what I thought , a bunch of weirdosquote:

That's a very good idea. Would that give you something like a 10W-35 if mixed evenly?
Palut, given that mixing is not a linear equation, I can only take a guess at what viscosity the final product is. Someone has an online calculator that figures this out. I did a UOA about a year ago with that mix in my car.
I guess the "Ford Motor Company" has it all wrong then.quote:

Although I would never make a mix like this, I can see that it would make a good high 30 weight oil, something like 15w30 or so, with the ester content, PAO content moly content, etc. yet is shear stable and has somewhat of a diesel-level additive package. Could have its benefits.
Personally, if I wanted this stuff, Id probably get redline 10w30 with the CI-4 diesel spec...

I'll mix to get rid of odd stocks ...and I'll do it to cut some 15w40 HEDOs to more acceptable viscs for one of my older cars.
I even add to my "odd stocks" on occasion. The local Advance Auto had a close out shelf. I got three quarts of Pennzoil full synthetic (all they had) for $0.99 ..and they had 3 gallons of Rumila 30 weight also for $0.99 a gallon.
How can you pass that up???

I suspect mixing of oils goes on a lot more than any of us oil freaks imagine. Just think of all the less technically inclined people who stop at a service/fuel station, find they're a quart low, and buy and add whatever is available at the moment. I believe that's why oil companies go to great lengths to ensure the compatibilities of their engine oils with a great variety of others.
Does mixing oils improve it's performance? Well, I don't think I've seen a UOA here that was statistically significantly worst. On the other hand, I don't think I've seen one significantly better either.

Well..considering that Syn blends are little more than adding some Group III or PAO to the base oil I think some thinking on what to mix will give some improvements. The GF-4 oils in some cases received an improvement by merely adding some Group III or PAO to the existing base. And adding the RedLine will improve the quality of the base oil. It would be hard to argue against that fact. I have previously mixed Mobil 10w30 and 15W-50 to cut down oil consumption.
Also I have a track record on 4 vehicle which I will be using the Redline mix. I think I'll be able to prove there is an improvement.
Just to clarify my post, I was thinking strictly about synthetics. I've been using predominantly synthetics for so long, that's usually my first frame of reference. I would imagine adding the right synthetic to the right dino would improve the dino significantly.

I was reading an earlier post where TallPaul was mixing
1 qt Valvoline All Climate 20w50
1 qt Shell Rotella 15w40
1 qt NAPA straight 40
1 qt Mobil 10w30
1 qt Redline 5w20
What kind of junk is this, is he looking to distroy his motor???

A lot of people mix oils simply because they've got lots of different oils in their oil collection that they want to get rid of, but don't have enough of any one brand to make up a complete oil change.
Some of it is definitely curiosity too, I think mixing is safe as long as you don't try to push the interval too far. It's definitely neat to see different UOAs on the mixed oils.

I like the idea of mixing a company's conventional dino oil with their HDEO. For example, mixing Chevron/Havoline 5w30 with Chevron Delo 400 15w40. It bumps the viscosity, adds a more robust add-pack, and is useable all year long. By themselves, those Delo's get quite thick in winter time.
Zollskin you seem really interested in making a "home brew", have you ever done it before? And if so what would you use?
