I generally get the mobile one when on sale at advance auto. It comes with either a k&n, bosch or mobil 1 filter. Depending on the sale. You save around $40 if you catch the sale!
I don't think we have sales here! Our local store did turn into an Advance Auto though so maybe I'll keep my eyes open extra wide the next week or two just in case.
I have used Mobil 1 in my Jeep and my 63 Ford Falcon primarly since I owned them. I have tried Royal Purple in the Jeep and Motorcraft in the Ford. But for the most part Mobile 1... And really I am going to use it for now on.
As for Filters.. On a filter test site the Mobile 1 and K&N Oil Filters are nearly identicle. They flow well but they dont filter well.. This is really a mute point if you change oil when you should. If I remember right Fram did better in filtering than those 2..But from what I can read the Wix is one of the best you can buy and really a fraction of what K&N and Mobil 1 cost. I got my last one at O'Riley's but other places sale them, in Hawaii the Don Quote sales them (like a K-Mart type store)..It was less than $10 for the Wix and was like $15 for the Mobil 1 / K&N..
Plenty of threads on using Amsoil but I think running an oil beyond the recommend oil change of what the owners manual says is asking for trouble. Use whatever oil you want, just follow the MX schedule of the Owners Manual.
I have the K&N filter in right now but I haven't done any oil changes or analyses so I don't have any opinion other than Mr. Darcy is running great so nothing detrimental!
what is your projected oil change interval with mobile 1?
the filters are good and made for mobile by champion labs.
My plan for the interval is to start at 4,000 miles but rather than a change do an analysis and then if the quality is still good retest every 1,000 miles until I get to the mileage recommended by the "guarantee" that mobil 1 has, which I honestly can't come up with right now. Been a long day :yawn:
I use mobil 1 from walmart. usually $23 for 5 quart jug. Not sure if that's the EP or not. Then I go to NAPA and get the NAPA gold filter which is WIX.
I used Amsoil for a while a couple years ago. The first thing I noticed when I switched to mobile1 is that I heard a lot more top end noise on startup. With amsoil I heard practically no noise at all. Just the regular ticking these 3.7s usually have.
edit: I'm thinking not the EP. well, better be more awake next time I go.
I really appreciate this information on the oil comparisons! Unfortunately, I have done the research and I can't find any way to get Amsoil so it's either the best Mobil 1 I can find or one of the generic brands they carry down here.
When it comes down to it, no matter how much help and research goes into a decision, it all comes down to what is being shipped in. I am completely at the mercy of my isolation so we'll just see what happens!
