Is there really any benefit to mixing syn/dino in the winter months? For example: 4 quart sump, mix 2 quarts mobil 1 and 2 quarts mobil drive clean 5000. If 5w30 viscosity oil is used would it really matter?

No.
Just use the 5w30 conventional and be happy!
I've operated in 20 below with 10w30 conventional (before 5w30 came out) and other than waiting 2-3 mins before taking off and keeping the RPMs low (which I do when it's 90 degrees until the engine warms up fully) your good to go.
I've never had a problem starting or operating in lower temps with normal oils. And everyone of my engines go the distance with ease.
Take care, Bill

Probably won't help a lot. But if you get to the boarderline pumping of 5w30, the 5w30 syn will do better than the conventional 5w30. And Personally I am uncomfortable with even 10w30 Synthetic in Pa. I used it in the past and it started at -10F. But I just don't like it.
So who asked ya Flux?
Not what he said, anyway. Your version, "I dunno,
but it didn't seem to hurt" is wrong. He said, "I've done it many times (mix PAO and dino usually of the same brand) and I don't know if it helped anything but it didn't seem to hurt either."
YOURS was the "wonderful" addition to the original post; an insult to another user (that would be PBM) with about 80 times your post count and a year and change longer on the board. Grand contribution yourself, there, Flux..
I'm no mod, but have a heart..

Greetings. I'm new to the site. I'm a mechanical engineer and ASE Master & L1 working at Shell/Pennzoil/Quaker State R&D in Houston.
Just switching to synthetic does NOT necessarily mean you get better low temperature performance - but it usually works out that way. You can mix them together, when we do, we call it a synthetic blend. It may give slightly better high and low temperature performance compared to a conventional oil - but it really depends on how your two original oils are formulated.

Well according to Mobil's calculation mixing-in 50% synthetic should equal Mobil 10000.... since Mobil 7500 is approximently 25% synthetic.
Go for it. Sounds like a nice blend.
Ferndog - Do you have a recipe for a blend I can mix at home? I use oil that's approved for a GM with the Oil Life Monitor so any homemade blend has to be that good too. THANKS
FD...
You are about to be hit with a million questions, after opening that door. Glad to have you on the board. Now go suggest to your group that you market your oils with a list of the components used plainly displayed on the back of the label, just like nearly every other marketed item has. Here's an example:
GrpV components 75%
GrpIV components 15%
Unobtainium good stuff you need in GrpI carrier oil because it wont dissolve or will fall out of every thing else 10%
Thanks!
And again...
Yeah, but these are questions and answers that rise to the level of State Secrets.. Besides, who else but us would ever care? Their job is to build brand recognition and loyalty with the knaves, and THAT does not include sharing the formulas out with the paying customers..
Pennzoil Johnny says I can mix the old EOP PP with the new GroupIII, so that's good enough for me!

I think we did that with Tariq Aziz when we told him to get out of Kuwait. Sent him back to his "group".
Welcome, Fern, we'll be happy to have yo, I'm sure..
I've never tried it, but my personal guess is that it wouldn't cause any harm (assuming the oil formulas don't clash, and you use a decent viscosity for the desired purpose). And it would probably start up better than going pure dino in the winter (but probably not as well as going full synthetic in the winter).
However, there is also another type of "mixing" to consider, and that is mixing the viscosity of the oil. While I'm still fully synthetic in my cars, I have been experimenting with mixing in thinner viscosity oil for the winter. For example, instead of going pure 5w30, I've started adding about 1 qt of M1 0w20 to my oil mix. So far it seems to be working fairly well, with the small amount of thinner oil making a noticeable difference when the car is very cold. At the same time, I'm not thinning the oil so much that I should have problems on those few occasions when I really take a long trip in the winter (and where therefore, the oil fully gets up to it's hot viscosity)...
I just got back to the site after a few days away and I see that Flux gave my original post a little tickle and that toocrazy defended me.(thanks toocrazy). Let me clarify what I meant. Awhile back someone (from PA I think) posted that they had mixed dino and synthetic and that it actually caused hard cold weather starting. They felt that there was
possibly a clash of additives or base oils. I have mixed several different dinos and synthetics in varying percentages and have never had that experience. What does this mean? I don't know but thats what I meant by "it didn't seem to hurt either".
