I have a 2500HD 6.6l gas engine and will be using this filter UPF63R. Do y’all have any info on this filter? It appears to be a more robust filter than the PF63. Who manufactures it?
Hello,
I’m torn between Mobile 1 100% syn. and Castroil Edge SAE 5W-30. I’m sure they are both great oils but what is y’all’s opinion on the two. I will be pulling a travel trailer that weighs about 8000 pounds some of the time. Thanks in advance.
