Since the day I bought my ex with only 65k on it I have used Mobile 1 Full synthetic with the fram filter that will last 7500 miles. but I change my oil between 5-7k depending on how much I'm on the highway. I now have 104k on it in 2 yrs and it still runs like a clock.
I've been running Royal Purple full synthetic 10w-30 in my 5.0 for almost 10,000 miles with no problems. In a few weeks I'll be doing my 3rd oil change with Royal Purple. Great oil!
I am currently running Amsoil Signature Series 0w30 (Dead Link Removed ) in my 4.0 SOHC. Prior to that I used Amsoil Series 2000 0w30 (Dead Link Removed ).
aldive, I am very interested in this Amsoil By-Pass system. Getting 30MPG in an Explorer is awesome. But I have a couple questions about it. It looks easy, but really, how difficult is it to install and take care of? Would this work on my Explorer? And, why aren't more people doing this? haha
As far as taking care of it, there is nothing special required. Simply change the filters at what "you" feel as an appropriate interval. I also periodically check all the hoses and fittings for leaks or abrasion. Also, I pull samples to send to Blackstone Labs ( Dead Link Removed ) for UOA.
Beats the hell out of me. I presume many people have been brainwashed into the archaic 3k OCI and the fear of the unknown ( the science of a UOA ). I am in no doubt many think it costs too much too.
I am amazed that so many still use conventional oil. To each his/her own.
To answer your question, I really don't know why. However, I assure you I will never have a vehicle without a bypass system and quality synthetic oil.
Thank you aldive. I'm going to look into this deeper before I decide anything. But definately, I am going to keep this high up on my list on things to do. If there is anything else you would like to let me know about this, feel free to tell me.
Theoretically, it is possible to increase mileage by some unmeasurable amount due to the oil's reduction friction by having less particulate matter in the flow.
I use bypass oil filtration because its the best way to filter oil and you can greatly extend the OCI safely.
Hmm. Well I'll still have to think about it. Right now it's sort of a tie between this or the exhaust.
But aldive, I used your advice on your "Quest for 30 MPG" on not driving the X like a race car, but just nice and easy. And I have to say it I noticed an increase in the use of gas.
