During the fall I switched over to Pennzoil Long Life 0W30 blend HDEO. I just changed the oil on the car, and now I am on the second interval of Pennzoil Long Life 0W30. So far I am very pleased with it's cold weather performance.
Now my question is, would this oil be a good choice to run year round? It has a vicosity of 11.8 cSt @ 100C, which is considerbly thicker than the Pennzoil 10W30 dino (10.5 cSt)that I used to run in the summer. It also has a HTHS of 3.45 which is better than that of 10W30 dino (3.2). Plus, since this oil has 45-55% PAO, it should hold up considerbly better than a dino or other lesser blends. I don't really see any disadvantage to running this oil year round, and it will certainly simplify the logistics for my oil purchases.
The oil is going into my daily driver/run around car, a '85 Olds with a 307 Olds V8 (similar clearance specs to a small block Chevy). It gets a lot of city use, a mix of short and medium trips (although usually several throughout the day). The car usually gets one or two good highway trips per oil change interval. I should note that I am not willing to step up to a full synthetic with this car. I also intend to drive it until the wheels fall off.
I can get this blend at a very good price, which is part of the reason why I use it. Additionally, winters in this area can go below -35C, so I think the 0W30 is a necessity during the winter months. Summers here typically don't see hotter temps than 35C.
So any thoughts on the above? Does anyone have a better suggestion as to what oil to use during the summer months?
