Still wondering which oil filter to use? Filter Comparison Chart within
Not the end-all be-all information, but it was intereseting none the less.
Full Article: http://www.gmtruckcentral.com/articl...lterstudy.html Click on this link for the full grades all filters received. http://www.gmtruckcentral.com/articl...gradesheet.htm Of note, in this test the best filters were (there is a slight weight for price too): 1. Fram Xtended Guard 2. Mobile 1 3. Royal Purple 4. Aimsoil (tie overall score with below) 4. K&N (tie overall score with above) Worst were: 1. Shell 2. AC Delco 3. STP 4. Proline 5. Fram High Mileage (it filters better than lower tier Fram, but is built poorly and costs more) |
Links should work now
Sorry about that :) |

The PF-48 OR the UPF-48R ???? |
The Mobil 1 filter is not a C6 Corvette filter, neither is the AC Delco filter.
|
I use the UPF48R. It's not expensive and I talked my dealer into ordering a case so they could sell me one. :D
http://static.summitracing.com/globa...ACF-UPF48R.jpg Info on this filter here. |
This is just a reference to how the particular filters are constructed and the quality found within them. I would assume that would be carried across the particular brands filter lineup.

Then the info is not exactly correct I would think. The PF-48 and the UPF-48R ARE different in their construction. The latter is a HEAVIER constructed filter..... As well, it has been stated here on this forum that there is only one or two companies that make ALL the filters we find on store shelves. Their manufactured to specs according to whose name is going on the filter. this thread has had multiple runs here on this forum. so, cutting through the chase so to speak, PF-48 started out on C6Z and changed in '10's owner manual. Now, the UPF-48R is listed in my owners manual where the earlier version was before. It's constructed heavier because the ZR1's oil pump creates enough pressure to burst the earlier PF-48. So GM now calls for the UPF-48R for BOTH Z06 AND ZR1. (not that Z06 has the same pump as ZR-it does NOT) But, the Z06 CAN still use the early one. |
Thank you for posting this test.
I wonder how many are going to bawl because their favorite ox is getting gored? Kinda like the air filter tests where the cherished aftermarket air filter admirers squawk in protest when their performance filter fairs poorly! :D |
For the most part,we have always used Wix filters.

A commercial contractor once gave me that tip and it was an excellent one. I try not to assume anymore. |

The fact that they aren't specifically for the C6 is somewhat irrelevant in regards to the information it's trying to get across. Like I said, it certainly is the end-all be-all report...it's just a tool to help make more informed decisions. |
Here is a different oil filter study with some different opinions.

I do not think price should factor into the grade.
I do not care how much the best filter costs....as long as it is the best. |
