Totally agree. I use GM Filters as a personal preference. I don't see why the Fram filter wouldn't be sufficient. In fact, I used Fram a number of times on the Wave personally, no problems. In fact, if I don't get a GM filter, I get a Fram.Originally Posted by AveoRob
The only reasons I see for using synthetic oils is the longer service interval and environmental concerns (mpg, disposal, etc...), which these days is not a terrible idea. You can reduce waste by 50% or more.
