Maxlife vs Durablend vs WB cold flow ??

[lucerne06]

just wondering if a mistake on the valvoline website spec sheets...it says that maxlife(syn blend)in 5-20, 5-30,10-30 all have the same -42 cold flow pour point, while the durablend is -36 (5-20), -36 (5-30), -33( 10-30) and the WB is -36, -36, -33 as well... is this correct, and why would maxlife a "Thicker Oil" have a lower pour point then the durablend if it is correct??

It's probably because Maxlife has a higher percentage of a more robust synthetic base oil in the blend. I don't know if it still does, but the synthetic base oil in the Maxlife blend use to be PAO.

I have all three oil's and just wondering what I should put in for the winter in PA. going into a 2002 1.8L toyota and a 1997 1.6L toyota

Personally, I'd look at the cold-cranking specs as your decider.

In that regard, Durablend wins, hands-down:

Maxlife 5w30: 5800cp @-30C;

Durablend 5w30: 4800cp @-30C;

Valvoline 5w30 conventional: 5500cp @-30C

Pour-point isn't really a good indicator of how well an oil will perform.

I was forced to go to a Valvoline quick change two winters ago, and went with WB because of price. I wasnt going to pay $60-$70 for a Max Life change. It was the middle of Feb in ohio, the Blazer was parked outside. No problems reguarding cold starts with WB.
