The filter is the size it is likely for clearance issues.
Any longer than stock and it will hang below most other parts of the undercarrage and likely get smacked by items like speed bumps and such

Stress?
I don't think "stress" has anything to do with oil filtering capacity. As far as "stress" goes, I know I put a helluva lot more "stress" on my Vette engine than I ever put on my truck engine.

Please re-read my post. The clerk said that the smaller size was for quicker oil pressure increase at start up. It has nothing to do with clearance. The oil filter is nowhere near the lowest part of the car's undercarriage. I was just wondering whether the trade off for quicker oil pressure was worht the decrease in oil filter capacity. Can you tell me what the size of the "stock" one is?

I have been changing oil filters on all makes of cars for over 30 years. Worked in a garage through high school and some of college and changed my own on many cars. The size of the filter has to do with clearance. And larger is not always better. I can't say the clerk didn't know what he was talking about, but in all my experience, I have never heard that a smaller filter is quicker up to pressure. Why would it be? They are always full when the car is sitting. In any case, Chevy says the small one is fine, I think they know how to engineer an oil filter.

The filter on my Nissan Murano is 2 1/2 inches in diameter and 2 1/2 inches long, I HAVE SEEN BIGGER OIL FILTERS ON LAWN TRACTORS !

Thanks, Mick. Just because you're a GM engineer, doesn't mean you're a genius.
OK, after all this discussion, I admit, a small filter will work just fine. HOWEVER, I think a BIGGER filter will filter BETTER! Assuming there are no clearance problems. Before installing, I will ask Clarance to check my clearance. I might even ask Victor to check my vector. Roger? Huh?

Oil Filter Capacity
I only have a degree in Diesel Mechanics and Heavy Equipment Technology and I have never heard that "pressures up quicker" crap-ola
The counter "genius" was really digging for that snappy come back! It might only count on the initial filling of the filter after the oil change. I do also agree with the battery/computer location thing too. Is that the ONLY place they could have located those two items? I would usually not give to much creedence to what a parts counter "clerk" advises on specific car models or manufacturers and the associated parts that attach to said vehicles.

Oil Filters have always amazed me.
I fail to understand why there are so many different sizes and different threads. There seems to be no connection with filtering ability and engine/vehicle size.
Why don't the Manufacturers specify 2 or 3 different sizes and use them in all applications? Think how simple this would be. A, B, C for diameter and add 1,2,3 for length ( or some other designation). Nine total fits all???
Surely the dozen or so of the same apparent size could be standardized to do this. If you look at the back pages of a Filter Manual there are pages of sizes differing by 1/4" or just the Thread size.

Oil Filter (update)
To all who said that size matters (clearance issue), you were right. I apologize. I was wrong. I was under my Vette the other day while my muffler man was finishing up my exhaust, and I was able to see just how low the filter is. Anything longer than the "shorty" stock filter would be snapped off at the first speed bump! And my car hasn't been lowered! Thanks to everyone who posted. It has been a learning experience.
