mjhpadi Posted December 28, 2011 Report Share Posted December 28, 2011 I have managed to discover that Royal Purple oil filters are manufactured by Champion Labs. These filters seem to be equal or above quality to K&N and Mobil One to mention other filters. So far it appears that these filters rank in the very good category but that is only from the limited info I have been able to find on them. Also it seems that they are only found at Pep Boys as the national chain store routinely carrying these filters. Still not a lot of firsthand info about Royal Purple oil or likes and dislikes about it. I am trying to find as much info as possible, as I am considering using these on the SHO. So any firsthand knowledge anyone can add is a plus. Link to comment Share on other sites More sharing options...
Showgun Posted December 28, 2011 Report Share Posted December 28, 2011 Thanks for doing the legwork Mark -- I've ordered some Mobil 1 filters for now since they're available thru a local auto parts store (PartSource) -- but let me know what you find out about the RP filters especially the price. Mobil 1 no doubt are good but they are pricey up here at just under $17/ tax in. Nobody I've talked to so far knows about RP yet but I'll still keep looking. If I learn anything I'll be sure and post here. Cheers, Colin Link to comment Share on other sites More sharing options...
mjhpadi Posted December 28, 2011 Author Report Share Posted December 28, 2011 Thanks C., I've found that on-line (Summit) has the cheapest price I have found at $12.96 but they want $6.95 shipping on the filters. Last time I bought Mobil One filters for the Explorer I got them at $8.00...but I bought 12, since at that time I was also using them on the Lincoln. So the RP filters seem to be more expensive then the Mobil One, but I am continuing my search...going to see if any of the local stores are willing to give a discount if purchased by case lots. The Royal Purple come 6 in a case...if I can find a good price I might make the switch. Since I know I can get Mobil One at a discount. Will keep posted on my findings.

smokingozzy Posted December 31, 2011 Report Share Posted December 31, 2011 I have used RP 5w-30 in my Lightning truck for about 6 or 7 years now with no problems. I usually change it somewhere btw 3,000 and 5,000 miles. I have not had any engine related problems (knock on wood) so far! My truck runs 11.80s with a small shot of N2O. I usually use motorcraft or K&N oil filters. I definatly will put it in my MKS when the free oil changes run out from the dealer!!! Link to comment Share on other sites More sharing options...
