Cold flow Hav dino vs. PP

[MustbetheTG]

Anyone have the cold flow properties of Hav dino on hand??
How does this compare to the new PP for winter use?

The most recent PP specs are:
Platinum 5W-30 Group III (PDS dated July 2006):
MRV, at -35 degC: 14,800
CCS, at -30 degC: 5150
Pour Point, degC: -39

Havoline 5W-30 SM/GF-4 (PDS dated Sept 2006):
10.8 cSt at 100°C
64.8 cSt at 40°C
CCS at -30°C 5,700 cP
MRV not listed
Pour Point -36°C(-33°F)

Do you think there is much difference between the two to justify the extra money for PP for the purposes of extra protection for subzero starts??

Close call...but I think the PP would flow a little better below zero. It may also hold it advantage for a longer amount of time, but I'm guessing. Stick a quart of each in your home freezer and perform your own pour test.

You'd have to decide if it was worth it to you.

How about running each oil maybe...4k miles then freezer test?
Rickey.

IMO i wouldn't take the chance,run the PP

Worried about cold flow that much - then use 5W-20 Havoline in the winter.... perhaps a 50-50 mix with 5W-30 would help also.

Well, I bought the PP and put it to the freezer test against the Hav and the results......a close call, but if it was a photo finish, I think the Hav would have it. I thought both oils were pretty thick for being just below freezing. Which flow stats are best to compare? MRV? I'll have to take a sample of each when I change the oil and retest....

Really???, wow.

Don't need the freezer, just leave the oil bottle outside, it's 22 degree F right now in upstate New York.

It's 22*F in south Georgia right now.

To the OP I would just use the Havoline.

My freezer gets down to around 0°F. I believe most get down to at least 10°F.

I would assume synthetic would flow better than any dino.
